So, how much do double glazed windows cost in 2023?

Well, let’s start off by looking at the buying / selling process to see what we can do in advance in order to give ourselves the best chance of getting a good deal on cost.

Company Sales Representatives

UPVC Windows CostIt’s likely that we can put Double Glazed Windows sales representatives into 2 simple categories

  1. Professional sales “closers”
  2. A person who comes to “measure up” and give you a quote

It’s obvious that both will want you to buy their product, but the “professional sales closer” is reputed to be more likely to take the time to link the features of the product to what he or she has found out about what you want or need. In that way a pro-closer can use emotion or logic (usually emotion) to persuade you to buy their product.

A person who comes just to measure-up & give you a price may appear to be the best person to deal with, but experience tells us that both will have the option to offer a better price if they truly want your business.

Whoever turns up, it’s not a good idea to sign any contract or give deposits based on what you see or hear on their 1st visit.

Get several prices from different sources, this will give you a broader picture of what the “average cost of double glazed windows” is for your installation, and can often work for you in negotiating a lower price.

If you show a company, that you feel you can do business with, a rival quote with a lower price for the same product, it can tempt them to try & match it to secure your order.

Product Specifications – the basics that you should expect, or need.

The next thing is to take a moment or two to consider what you really need to buy in terms of your new windows, because there are some things priced separately that can quietly push up the cost.

  • Single, double or triple glazing – single glazed is no good for external doors and triple glazing may sound great, but not be a value for money option for you.
  • Safety Glass – double glazed units can have tempered or laminated glass, at a cost.
  • Energy efficient glazing – apart from special coatings, such as “low-e” glass, you can have the centre of the glazed unit filled with an inert gas such as Argon – again at an extra cost.
  • Insulation gap for sealed glazed units – the gap between the 2 glass panes in a double glazed sealed unit can be varied, from 5mm up to around 21mm. Expect to pay extra for the wider gap.
  • Coloured or wood-grain finishes – Some colour or wood-grain finishes can add from 10% to 25% to the cost.
  • Opening sections – some installers make an extra charge for a window section to open.
  • Furniture – specialised handles & locks can be an “added extra” cost
  • Energy Efficiency – A++ are the highest rated, but may come with a “price-tag”
  • Local or National Installers – you may be more comfortable dealing with a “big-name”, but there are loads of reputable local companies with great products and low prices – check a few out.
  • Timing – if it’s a busy time of year for installers and their order books are full, you may find they don’t offer discounts at the time of your order – can you wait a bit longer to have your windows fitted?
  • Can you get a deal on triple glazing for the price of double glazing?

Construction Material

Timber Double Glazed Windows & DoorsWhat material do you want your windows to be made from?

The typical choices would be Wood, UPVC or Aluminium. As a rough guide, UPVC windows can be found in the market at up to 30% cheaper than wood or aluminium windows.

Design Options

Different double glazed window designs will have different price scales, the more “complex” the design the higher the price is likely to become.

  • Casement Windows – a typical side opening window, many low cost examples
  • Sash Windows – vertical opening sliding sashes, timber sash windows can be pricey.
  • French Windows – more popular as a door set. Matched pair of windows hinged at the sides open from the centre.
  • Tilt & Turn Windows – available in casement or sash style (even tilt & turn doors)
  • Bay Windows / Bow Windows – usually constructed as a curved set of casements, built to order.
  • Porchesnot quite a window, but a useful addition to your home

All of these designs can be found in either wood or uPVC.

2023 Double Glazing Cost for a 3 Bedroom House.

Fitting double glazing seems almost like a national pastime in the UK. But as with most home improvement of this type, there is a wide variation in price across the market.

So what does double glazing cost for a 3-bedroom house in 2023?

For situations where the whole window is being replaced (rather than fitting secondary double glazing), here is our quick guide.

Estimating the Costs of Double Glazing for your home in 2023.

The first thing to do is to establish how many windows you want or need to replace.

Not all 3 bedroom houses have the same number of windows. Not all 3 bedroom houses have the same style of windows. You may have Sash windows or even a bay window (or 2).

On the other hand, you could be talking about a 3-bedroom bungalow or even a 3 bedroom flat.

If we take a fairly standard property fitted with casement windows, then this is likely to be the cheapest to fit with double glazing. If you have Sashes or bays, then the cost will increase markedly.

Is triple glazing cost effective – find out more here.

Secondly, you should settle on the type of material you want the windows to be made from:

  • UPVC.
  • Aluminium or Aluminium clad.
  • Timber – softwood, hardwood or even engineered wood.

I think it’s fair to say that UPVC replacement windows are commonly accepted as being the lowest cost option (excluding softwood). Aluminium and hardwood windows are significantly costlier.

An average 3-bed semi property will likely have 3 to 4 windows at the front & back. Detached can add maybe 2 on the sides. For the purposes of this article we will assume 8 to 10 Casement or Sash windows being replaced.

Cost of Double GlazingThirdly, decide upon the energy rating for the windows (Window Energy Rating or WER)

The energy efficiency can be graded from “A++” to “G”. An energy rating of “C” would be the lowest recommended for general use (also building regulations).

Key features that impact the WER are:

  • Thickness of the double glazing unit (up to 28mm)
  • What is inside the air gap of the sealed unit (a gas like Argon or dehydrated air)
  • Type of glass – low emissivity coatings.
  • Frame construction (multi chambered)

The correct fitting is also essential to maintain integrity. Even the best rated windows will perform poorly if they are badly fitted.

In this case, finally, personalisation will affect the cost.

For UPVC & Aluminium windows, it can cost more to have coloured options and wood grain textured effect surface finishes.

Use of Leaded glass, frosted glass and patterned glass will all impact pricing structure. As will the number of opening windows – in many cases, window sections that open can attract a small extra charge.

If you want to use a different variation of frame styling, such as the flush design, then there is also going to be an impact on the pricing structure:

So, what is the cost of double glazing a 3-bed house 2023?

UPVC windows prices

Basing the estimate on fully fitted UPVC casement windows (WER B) you could expect to find prices in the region of between £250 to over £400 per window. If you do all the windows at once (8 to 10) then you can expect prices to range from £3,000 to £5,000.

Aluminium windows prices

Aluminium windows are costlier than UPVC. For a 3 bed semi you can expect to find prices in the region of from £5,500 to £6,500 for 9 to 10 units fitted.

Hardwood windows prices

Probably around the same price bracket as Aluminium. 8 to 10 hardwood casement windows would cost from £5,000 to £6,000.

Comparison Table
Number of units uPVC frames Aluminium frames Hardwood Timber frames
up to 4  £1,500 – £2,000 £2,300 – £2500 £2,000 – £2,500
up to 8  £3,500 – £4,000 £4,000 -£4,500 £4,000 -£5,000
up to 10  £4,000 – £4,500 £5,500 – £6,500 £5,500 – £6,000
up to 12  £4,500 – £6,000 £6,500 – £8,000 £6,000 – £7,000

If you have a bay window that needs replacing, then you can expect 3 section UPVC Bay window prices to be in the region of £1,100 to £1,500 depending on what you actually want.

We recommend that you get at least 3 or 4 written quotes from a selection of installers and then compare prices to find yourself the best value for money option.

1What are bifold doors & how do they work?

The “signature” feature of a bifold door is the way it opens to the sides and leaves almost a 100% clear exit or entryway. Once slid to the sides, the doors fold or stack neatly out of the way allowing total freedom of access with nothing to block the view.

The way the panels move, is to fold into each other in a zig-zag concertina manner, with the hinges allowing each door to fold into the next.

The doors can be fitted to move to left or right – or left & right. They can also be “Stacked” inside or outside the frame.

2Bifold Doors 2023 Price Guide

There are quite a few things to take into consideration when looking at average bifold doors prices.

Factors such as the material you choose for the frames is going to impact upon prices, as are the type of glazing, the amount of labour and even where you live can have some effect.

How much does it cost to install bifold doors?

Most bifold doors cost prices shown online are for supply only. In other words, the installation costs of the doors are not always included so you should take this into account.

However, the cost of installing bifold doors up to around 3.0 metres wide should be in the region of £550 to £650. For larger installations of 4.5 metres to 5.0 metres it may cost up to £900.

  • We recommend that the installation is done by a FENSA or CERTASS accredited professional.

Bifold door prices online generally assume that the new installation is being fitted into a ready-made opening. If this is not the case for you, then you need to budget for all the potential construction work that may be required.

There are a couple of other things to bear in mind if you are creating a new opening or enlarging an existing one.

Permitted development rights may cover you on this, but it is going to be prudent to confirm this with your contractor or Local Planning Department before knocking a hole in the wall!

If you live in a listed building, Area of Outstanding Natural Beauty or have any restrictions on your permitted development rights, then you will need permission from your local authority beforehand.

UPVC, Aluminium & Timber Bifold door features.

A set of bifolding doors will typically consist of anything from 2 to 7 side by side door panels (panes) joined together by vertical hinges.

To open them, once the locks are disengaged, you simply slide them to the sides of the opening – either to the left, right or even both. The panels themselves can be configured to stack inside or outside relative to the main frame.

Bifold door rollersThe doors are mounted into overhead and underfoot tracks via rollers. The weight of the panels can be taken either by the overhead or underfoot track and are referred to as either “top hung” or “bottom hung” doors.

Top hung doors offer the advantage of allowing the bottom tracks to be set lower threshold, or you could opt for flush fitting door thresholds.

Also, taking the weight of the doors on the overhead track has the effect of making the doors easier to move. Top tracks don’t fill up with dirt like floor level tracks and so keep running smoothly.

However, you do have to ensure that the overhead door structure is strong enough to take the weight beforehand. Poor fixing points could cause the door track to work loose.

Flush fitting bottom guide tracks make for super easy access for elderly, infirm or disabled persons – and there is nothing for the kids to trip over!

Opening, Closing & Quick Access Options

With a 2 panel set, you simply have the choice to open left or right and in or out stacking, but with more panels come more options.

With 3 or more panels you choose the “Lead Door”, in other words, the one that opens first. But you can also decide if you want all the doors to go in one direction or some to the left and others to the right.

For example:

  • 2 panel: Either left or right opening
  • 3 panel: All 3 folding right or left. 2 right & 1 left. 2 left & 1 right.
  • 4 panel: All 4 right or left. 2 fold right or left. 1 lead door with 3 fold left or right.
  • 5 panel: All 5 right or left. 2 or 3 fold right or left. 1 lead door with 4 fold left or right.
  • 6 panel: All 6 right or left. 5 fold left or right with 1 “lead” door. 3 fold left & 3 fold right.

Bifold Door ConfigurationsAs you can see, you have the flexibility to adapt the way the doors operate to meet your preferences.

One of the panels can also be set up to be used as what is known as the “Traffic Door”. The traffic door is one panel fitted to open like a regular door. The advantage of this is that if you just want to pop in and out, you don’t have to move all the doors to do so.

TOP TIP: An outward opening / stacking door does not drip water all over the interior floor when you open them after it’s been raining!

Aluminium, Timber & UPVC Bifold Doors have quite a few features in common.

These main features are designed to make the doors more attractive, functional, and secure. Not only making your home look great but also giving you peace of mind.

  • Slimline frame options
  • Low-level or flush fitted threshold tracks
  • Storm proof weather seals (BS 6375/1:2009 / certified to PAS23/24)
  • Internal glazing beads
  • Nylon or stainless steel rollers
  • 3 or 5 lever mortice lock
  • “D” pad handles operating shoot bolts & multi-point hook locks
  • Up to 28mm double glazed units
  • Low-e, energy saving glass
  • Tempered / Toughened / Laminated glazing
  • Triple glazing options
  • Internal / integrated window blind options
  • Multiple colour options / dual colour options
  • Concealed hinges, gear & finger guards for the hinges
  • Fold flat handles

Low level or flush fitting door thresholds are a great feature for any patio door. Many flush thresholds are used in conjunction with top hung bifold doors.

Having no bottom door threshold to step over (or trip over) makes access easy for everyone, especially for wheelchair users, young children, elderly or infirm persons.

Fold flat handles are a more recent addition to the feature range. The ability to flatten out the handles lets the doors stack closer together, therefore taking up less space.

Concealed hinges not only help with streamlining the overall look, concealing the hinges hides them from any intruder intent on attacking the hinges to get into your home.

Finger guards are a good idea where there are little hands around – or even accident prone adults. Rubber strips are included along the vertical edges of the doors so that, if a finger does get in the wrong place, the potential of serious injury is significantly reduced.

UPVC Bifold doors

UPVC is used extensively for double glazed windows and doors. It is a naturally good insulator and easy to find anywhere in the UK.

Having a lifespan of 15 years or more for good quality products, and a relatively lower cost than aluminium or hardwood windows & doors, it also offers good value for money.

Available in up to 12 colours plus wood-grain effect, you can be confident that you will be able to find something to suit your home.

Aluminium bifold doors

Because it’s a lightweight and strong metal, aluminium can take advantage of slimmer frames than UPVC. This gives aluminium bifold doors a sleek and contemporary look.

However, using aluminium frames will cost more than UPVC frames, but you can exptect 25 years or more for their lifespan.

Make sure you look for frames with built-in thermal breaks. The outside of the frame needs to be isolated thermally from the inside because aluminium is quite a good conductor of heat.

Most frames use RAL powder coat paints bonded onto the surface. They don’t fade, crack or peel and have about 150 or more colours to choose from.

If you want a different option, you can go for a hybrid aluminium clad timber frame.

Bi-fold patio doorsTimber bifold doors

Using wood for a door, for some folks, is the best option in their opinion. They like the look & touch of real timber.

Timber bifold doors come in a few options:

  • Hardwood: long lasting woods such as Oak or can be pricey. African hardwoods such as Idigbo can offer just as good an appearance at lower cost. Good hardwood doors that are looked after can last for decades.
  • Softwood such as Pine or Redwood are low cost options but need a lot of TLC to keep them in top shape.
  • Engineered timber: Made from a composite of different timbers, engineered wood does not have a grain like natural timber. This means it’s less prone to shrinking or swelling. Easily machined into any shape and larger spans, this material is ideal for bifold doors.

Bifold Door Glazing

With a bifold door having such a large proportion of glass, getting the best energy efficiency performance should be seriously considered. Safety and security are also prime considerations,

So, what can you do to make your bifold door safer and more energy efficient?

  • Use 28mm sealed double glazed units – the widest readily available.
  • Use gas filled double glazing – adding Argon gas to the sealed unit reduces heat transfer.
  • Opt for Low-e glass coatings – benefit from solar gain as it keeps more heat in and cold out.
  • Toughened or tempered glass – breaks into harmless “granules” to void danger from cuts.
  • Laminated glass is the top option – extremely difficult to break even with a great deal of force.
  • Maybe use a glass tinting film (like in a car window) – folks can’t see in, but you can see out.
  • Glass films also help keep glass in place if it breaks.
  • Mulit-point locks and dead bolts – these make the doors very secure.
  • Anti-lift tracks – ensure the panels cannot be lifted out of the frame accidentally or on purpose.
  • 3 or 5 lever mortice locks – pick proof, bump & snap proof for extra security.

If you are overly concerned about security in your location, you could go as far as fitting an internal grille. Somewhat annoying to open & close all the time, but one of the most security minded options.

In summary


Fitting a bifold door is not necessarily the cheapest option, but in our opinion is well worth the extra investment and will make a big improvement in your home lifestyle.

The super wide opening and clear uninterrupted view of the outside serve to blur the line between the interior and exterior of any home.

With contemporary bifold doors offering high levels of energy efficiency, security, lifespan and visual attractiveness, what could possibly be stopping you from joining the thousands of folks who have already fitted them?

5 things to know about Bifold Patio Doors – and a guide to what they cost.

black patio bi-fold doorsPatio doors are considered to be a key feature in homes, providing security and easy access while flooding the house with natural light and a great view. Patio doors refer to all kinds of doors that in general open up to patios, gardens or terrace areas and are predominantly seen at the back of a property.

Whilst, traditionally, patio doors were limited to French or sliding doors, the market has evolved to include bifold doors – sometimes called bi-fold, bi-folding or multi-folding doors.

Depending on the size of the opening, bifold patio doors can be the ideal addition to a home.

The aim of the following article is to help those who may not know much about them to gain a fuller appreciation of just how versatile & appealing Bifold patio doors are by reviewing:

  • Features & Benefits of Bifold Patio Doors.
  • How much do different types of Bifold Doors cost.

Features & Benefits of Bi-fold Patio Doors

  1. Available types of material for bi-folding doors

Your choice of material for domestic installations comes down to three types:

  • Timber – 3 main choices between hard, soft or reconstituted timber. Hardwood veneers over engineered wood frames can be found.
  • uPVC.
  • Aluminium – can also be aluminium clad over a timber frame.

Timber Bi-fold doors have the “natural look” and are primarily appreciated for this feature. Timber products come in softwood with hardwood veneers, Hardwoods and engineered wood. Keep in mind that low quality timber doors can warp, shrink, expand or flex.

Veneered timber bifold patio doors are built from softwood, but have a very thin layer of hardwood applied to the surfaces so that they look like hardwood and can be quite cost effective. Hardwood versions are a bit pricier, but after all, it’s hardwood.

Engineered wood is very stable and does not suffer the same levels of expansion and contraction as natural woods. It is also “green” as it is sustainable and fully recyclable. You can paint it or stain it to any colour you like.

uPVC Versions are the “mid-ground” in terms of cost, not as cheap as softwood, but not as costly as aluminium or some hardwood versions. They are very hard wearing, don’t take much looking after and you can have them in different colours.

Aluminium bifold doors are slim & sleek. The paint finish on them looks great and can even offer a surface finish that is “grained”. They are not cheap but they are very strong, lightweight and last a long time.

  1. How bifold doors function

Bifold doors are doors that slide open, where the moving panels fold together side by side and neatly stack up against the wall.

Bi-fold patio doorsWhile Bifolds can look like regular patio doors when shut, the folding of the doors to the sides creates large and dramatic openings. These doors have the ability to fit into openings in a manner that creates a living space that transitions seamlessly from the indoors to out. This breakdown of barriers between inside and outside expands the living space and caters to optimum utility.

However, in order for bi-folding doors to be completely effective, it’s better to fit them to larger openings. When it comes to small openings such as around 2 metres or less, bifold doors won’t provide any more excess access space than, say, French doors would provide.

In order to optimise the efficiency of bifolds, it is worthwhile to consider key elements such as the threshold transition, stacking of the doors (in/out – left/right), which way the doors will be hung (top or bottom) before you go ahead and order some.

  1. Thresholds

The key feature of a set of bi-fold doors for your patio is, as we outlined above, the way the doors complete fold to the sides and create big space to transition from inside the of your home to the outside.

The threshold of the door set is something that can make or break this continuity of space. A high raised threshold can be ugly and annoying. In some cases, it can even represent a hazard (tripping) or a barrier to infirm persons or wheelchair users.

So using a low level or flush threshold is an available solution.  Bifold doors move on top & bottom tracks, either by the top or the bottom track taking the weight. Top hung doors need a good get free quotes for upvc windowsoverhead structure to take the weight of the unit but because of this the threshold on the floor can easily be a flush version.

Very low level, flush or recessed thresholds need to be able to cope with bad weather. They need to be able to drain water effectively and be windproof.  Ensure the design on offer has been thoroughly tested for this and won’t let water or wind into your home when the doors are closed.

  1. Appearance

How Much do Bifold Patio Doors Cost?Modern Bifold doors are slimline and less conspicuous than regular doors. Their slim profile has the ability to maximise visibility without having to compromise on the strength of the door.

However, for set with very wide individual panes, you should be wary of low quality uPVC profiles that may flex or distort if they are too slim and not reinforced. In a case like that, aluminium would probably be a better material to use.

Security is well taken care of, but is also unobtrusive. Strong hinges and anti-jemmy / anti-lift tracking systems keep the doors in place, whilst shoot bolts and multi-point locks make sure the doors are secure once closed.

Safety is also a high priority, because any glazing that reaches the floor will always be tempered, toughened glass. The inherent difficulty of breaking a sealed double glazed unit also helps. For those who want to go one step further, you can opt for laminated glass panels.

  1. Options and Average Cost of Bifold Doors

Bifold patio doors are made up from individual glazed panels or “leaves” and the size of the opening that you are going to fit them to will determine the number of leaves in the door set.

Working best with 3 or more doors, you can opt to have one panel fitted as a traffic door. This panel will be able to open & close just like a normal door. Allowing entry or exit without having to slide the whole unit to get in and out.

How much does it cost to double glaze a house UK?

Or How much should I spend on replacement windows?

There are many good reasons why homeowners buy new windows and doors. A lot of the time it’s because they are a necessity to replace older failing units. But maybe it’s just to make your property look more desirable before putting it on the market.

Whatever the reason, doing a bit of prior research on double glazing prices is a prudent move. Having an understanding of the average prices in the current market can really help in getting you on the right track to a good deal.

the differences between Casement Windows or Tilt and Turn Windows?

So, just how much do new windows cost?

You can find new windows prices ranging from as little as £100 and running all the way up to over £1,500 for a single unit.
  • Average sized Casement window prices range from £250 to £500
  • Average sized Tilt & Turn window prices range from £400 to £605
  • Average sized Sash window prices range from £250 to £500

However, how much you should pay is going to depend greatly on a few key factors – not least of which is your own personal budget:

  1. The style of window (Sash / Casement / French etc.).
  2. The size of the window.
  3. The material used for the frames (Aluminium / UPVC / Timber).
  4. The energy efficiency of the windows (A-rated / B-rated etc.).
  5. The size of the order (multiple windows work out cheaper than single windows)

Here is a quick example of how much you might have to pay to double glaze a house can quickly go up, depending on what you are looking for: (See our article What is Double Glazing).

Type of window or frame material with average single window prices

  • Casement window in UPVC: £100 – £500 per window.
  • Sash window using any material: Will cost 35% to 50% more than casement windows.
  • Tilt & Turn or Tilt & Slide UPVC: Can cost up to 25% more than casement windows.
  • Aluminium frames: Up to 25% more than using UPVC frames.
  • Hardwood frames: 25% to 45% more than using UPVC frames

There are more features that can still make a small difference to the price, such as how many openers in the unit, but we feel these are the main things to think about first.

Here we hope to give you a better understanding of why prices vary so much in order to help you in comparing the average price of double glazing online.

What are the main window styles?

1Casement Windows

One of the most popular types of windows in the UK, seen in almost every style of house, a casement window swings open outwards on hinges mounted at the sides.

You can get different versions of casement windows that swing open from the top or bottom.

2Sash Windows

Most often seen in older or period style homes, however, more modern homes are using this style of late. This style is easily identified because it slides up & down vertically to open or close.

The window is basically in two sections, top & bottom. Most often the bottom section slides on the inner side of the frame, the top on the outer side. If only 1 sash moves it’s known a “single hung”, if both move it’s called “double hung”.

The moving sashes slide within the outer frame inside guide tracks. The weight of the frames is counterbalanced either by tension “springs” or counterweights hidden inside the main outer frame.

Sash windows are probably the costliest type of window due mainly to the more complex design and counterweight mechanisms that are built into the frames – you can expect them to cost around 50% more than an equivalent sized casement window.

3Tilt and Turn Windows

Another design that is easily recognised by the way it functions.

Swinging open like a casement window, but only inwards, the main window can also be set to “tilt” inwards which gives a very good amount of ventilation in a secure way.

Once again, the complex mechanism that need to be built into the frames to allow the windows to tilt or turn is reflected in the prices. On average, you can expect a tilt and turn unit to cost 25% more than an equivalent sized casement window.

Fitting cost for a single window can be as much as £150, depending on the size. However, if you are having multiple windows fitted at the same time in a single order, then you can expect the fitting costs to work out much cheaper per window.

4French Windows

French Windows are really just smaller versions of French Doors. They work in exactly the same way.

Consisting of a matched pair of casement windows fitted side by side in a single frame, swinging on side fitted hinges, they can either open in or out.

French windows are generally costlier when compared to the same sized casement window, in the region of 20% to 25% more per window.

How much does it cost to double glaze a house UK?

Although there are occasions when you need to replace a single window, many homeowners are considering doing the whole house at the same time.

In this case, you are surely going to want to know how much does it cost to double glaze a house?

Below you will find a set of price guides. But as we mentioned earlier, there are a lot of factors that can impact on the final cost, so please bear that in mind.

How much do new windows cost UK?

Prices are for guidance only, vary by supplier and availability – get a written quote for accurate prices.

For example, Using the guide above you can get a good idea of roughly how much is double glazing for a 3-bed house.

A standard sized 3-bed semi might have 3 windows at the front, one at the side and another 3 or 4 at the back. So you may need 8 windows in total which should cost somewhere between £3,500 to £4,500.

However, if you want to add a new front and back door, you should budget an extra £500 to £1,000 for the front and about £500 for the back door.

How does the material used in the frames impact the average cost of replacing your windows?

The choice of material for the window frames themselves is definitely going to impact on the cost of the job. So, deciding which way to go is seriously worth considering beforehand.

The cheapest new windows are going to be timber, usually pine. However, softwood window frames are notorious for needing very high levels of maintenance.

This need to be “well looked after” has both a significant monetary and time cost over the life of the window. If you don’t look after softwood windows, they can fail very quickly due to shrinkage, expansion, paint peeling, wood rot, fungus, insect attack etc. etc.

Hardwood or engineered timber windows last a lot longer and need far less “TLC”. However, the initial costs are higher – this can be viewed as being offset by an extended lifespan and way lower maintenance costs.

UPVC windows are very popular in the UK due to their relatively lower up-front cost, excellent energy efficiency and long lifespan. There are literally hundreds & hundreds of installers across the UK offering upvc double glazed windows and this competition also helps to keep the prices stable – depending on the size & style, you could get a replacement UPVC casement window for £100 to £150.

Aluminium windows had a rough start, with poor designs, problems with heat loss and a drab grey colour. However, things have changed a lot over the years. Modern aluminium double glazed windows are sleek and stylish as well as strong and energy efficient.

As a metal that conducts heat easily, aluminium double glazing has to feature what is known as an internal “thermal break”. This ensures that heat transfer (or cold) is effectively stopped from radiating from the inside of the window to the outside (and vice versa).

Aluminium windows are usually more expensive than UPVC or softwood, but roughly about the same cost as hardwood.

How much do replacement windows cost?

In terms of what is the cheapest double glazing, based on a casement window sized about 60cm x 100cm you can expect to pay:

  • White UPVC windows prices range from £250 to £500
  • Hardwood windows prices range from £700 to £900
  • Aluminium windows prices range from £450 to £600

How does energy efficiency effect the cost of double glazing?

Cost of Double GlazingNew or replacement windows are graded so that consumers can see how energy efficient they are.

Each unit should have a Window Energy Rating (WER) label that shows the effectiveness and has a rating.

The label is colour coded and also gives a ranking of A++ for the best, down to G for the worst.

To get a AA+ rating on your double glazing, your windows are likely to need 28mm thick gas filled glazing units that have Low-e solar coatings.

As you might have guessed by now, all these energy efficiency “tweaks” cost extra. In short, a B-rated window is going to cost less than an A++ rated window.

See more on ratings here: https://www.bfrc.org/ratings

How does personalisation effect the cost of double glazing?

Most online prices that you see will likely be based on having a basic or standard window fitted as part of a bigger contract. Sometimes the prices may also be for supply only.

That means that, if you want anything other than the standard B or C rated white window, you need to pay for “optional extras”

Coloured UPVC windows can cost anything from 10% to 20% more than plain white – as can adding a woodgrain effect finish.

Window makers usually add a small charge for each section of the window that you want to be able to open & close.

Higher quality window handles, and locks come with a cost.

Using patterned, leaded, coloured, or frosted glass can be charged for, as can upgrading to toughened or laminated glass.

To illustrate our point here is a simple comparison:

A white UPVC double glazed window with no cill, clear glass, fixed panes (non-opening) can be found from £117.00

However, an Oak wood grain finish UPVC window with a 150mm ×30mm cill, frosted glass, one opening window with silver handles can cost from £170 – that’s almost half as much again on top of the basic cost.

In short, the best thing to do (in fact the only sensible thing to do) is to get your home measured and surveyed by a reputable double glazing contractor. Once that is done you will get a written quotation based on the survey detailing the exact works to be done and how much it all will cost.

Final thoughts

Hopefully, our article has given you several ways to answer the original question, which was “How much should I pay for double glazed windows?”.

As you can now understand, the amount of choice you have when it comes to buying double glazed windows makes for a diverse range of prices.

However, one thing remains the same when you are going to install new double glazing. You are recommended to work with contractors or companies that are registered and accredited via a “Competent Person Scheme”.

There are a few simple reasons for this advice:

  1. New windows & doors are covered by UK building regulations and must be certified that they meet these standards. Accredited installers will issue you with a certificate of compliance. If an installer can’t do this, you personally will have to arrange for inspection & certification of the work. Costing you more time, inconvenience, and money.
  2. Installers who are members of Trade Associations that offer competence schemes are vetted for quality of work. Both upon application and annually thereafter.
  3. Working with members of trade associations like FENSA, CERTASS, GGF, DGCOS, can mean you get elements of increased consumer protection. This may not be available to you from non-members.

All the installers on our Nationwide panel who provide quotes for our visitors are members of one or more of the above recognised trade bodies.

Exterior French Patio Doors – styles & designs for your home

French patio doors or sliding glass patio doors – which one should you install in your house?

Much like everything else when it comes to home improvements, you need to consider a few things well beforehand when you are about to embark upon installing a new set of patio doors for your home.

Whether you are looking specifically at fitting French patio doors, or a sliding style of patio door, it’s going to be very useful to understand the key design difference between these two different types of patio doors and what sets them apart from each other.

When someone mentions the term “patio doors”, it’s probably fair to say that most people would conjure up a picture in their head of a sliding set of doors – not unexpected, as the sliding design is very popular.

However, French doors have been around for hundreds of years and offer a lot in terms of appearance and function. This is why they have also retained a high degree of popularity in homes all over the UK.

In this article, we will be looking into French patio doors specifically, what advantages they offer over sliding doors, what to look for when buying them, and also look at the costs involved with installing French patio doors.

Full Glass French Patio Doors With Side Panels

What are French Patio Doors?

 

Oak French Doors

Oak French Doors

In terms of function, French patio doors are traditionally a side hinged set of double doors which open inwards or outwards depending on your preferences.

For the typical installation, when you open the doors, you will have full access to the complete width of the frame opening into which the doors are installed.

There are slightly different French patio door designs that have a centre mullion, or post. It’s not very practical to have a centre mullion for a main entry / exit external door, as it’s going to get in the way.

I would have thought that the only reason to have a centre post, is if you want to fit the doors so that one can open in and the other can open out instead of having both the doors open in the same direction. It’s more often seen in a French window.

The design is such, that you can open one door at a time or both together. You have the choice as to which door you make as the primary (the one that opens first) or the secondary.

In terms of appearance, there is the classic use of small glass panes, set in a grid of 2×5 or 3×5, 2×6 or 3×6 or full length plain glass from top to bottom.

In our opinion, a French patio door is all about classic styling and should stay with its roots and feature the mullioned dividers and small glass panels.

The very fact that this design uses 2 adjacent swing doors does give the French patio door a drawback when it comes to using them in a wider opening.

A standard sized single swing door panel in the UK is around 760mm to 838mm (2ft 6ins to 2ft 9ins), so, even allowing for the outer frame (and maybe an extender or two) if your opening is over 2000mm then you are going to be looking at making up the space with side panels.

Sliding patio doors Vs French patio doors

Both of these designs have their advocates and detractors and their own particular pros & cons. Here’s what we think are the four main differences.

1Appearance

Appearance has to be a significant influencer on your decision. If you prefer a lot of clear space, then a sliding patio door design could be for you.

French patio doors have slightly thicker frames as a result of the door design, and combined with the classic mullioned style, you could argue that you are losing natural light.

The counter argument for classic French patio doors is that they have an elegance and sense of style, whereas full glass sliding doors are “bland & featureless”. You could also use full height clear glazed French doors without the mullions in order to gain more natural light.

2Function

composite French Doors

White Composite French Patio Doors

After form, in this case, comes function. A typical patio door for the average family house will consist of 2 panels and at this size and configuration French patio doors have a distinct advantage.

With a sliding patio door of 2 panels, you will only have half the width to go in or out because the doors are fixed within the frame.

French patio doors allow the full width to be used as they swing out of the way.

Even with a 3 panel sliding door, you will be limited to around 60% clear opening for the same reason.

An equivalent width set of French doors (even with side panels) can match that percentage.

Sliding doors have a small advantage when it comes to interfering with actual living space, they don’t take up any when they are opened because they just slide within the frame.

On the other hand, French doors can open in or out, so if you have a smaller room, you can just have the doors open outwards.

3Security

The safety of your family and security for your personal possessions are high priorities and, whilst addressed by both designs, French doors do have advantages over sliding doors in this area.

Unless you are going for a real high spec top of the range sliding door, there is always the thought in your mind that a burglar could lever the door off the tracks and get into your home. You can’t do that to a French door because it is hinged – even where the hinge butts on a swing door are visible to the outside, you can’t remove the pins.

With a big glass panel on a sliding door, theoretically an intruder could smash it and walk through the resulting gap. The mullions in a classic French door design inhibit this action.

To be fair, you can’t really “barge in” a closed sliding door, but theoretically, you could do so, if you applied sufficient force to an inward opening set of French doors. However, to mitigate this problem, French doors use multi-point locks with shoot bolts on the centre doors that engage at the top and bottom of the frames.

The other alternative is to have your doors open outwards and then the doors simply can’t be “kicked-in”

It’s also much easier to notice when a French door is open, how many times have you seen a video of someone walking into a closed glass sliding door?

4Energy efficiency

 

If you are searching for energy efficient doors to lower your cooling and heating bills, then both sliding or French patio are a great buy.

However, French doors have a much tighter seal than sliding patio doors as when the locks are engaged it pulls the door into the frame, a sliding door is reliant solely upon weather sealing strips.

Sliding doors are mostly glass, and glass doors tend to transfer more heat than the frame itself, so having more frame than glass, as with a classic French door design, inherently reduces the incidence of heat transfer.

What are French patio doors made from?

 

You have four main choices when it comes to construction material and those are

  • UPVC: A very durable material that is a good insulator, Cost effective as a material, it lasts a very long time and can be made in a range of colours and wood effect finishes.
  • Timber: Softwood French doors are really more suited for internal than external use. Hardwood doors are very good to look at and if you look after them, they can last a very long time indeed. Engineered wood is a good option, as it is less prone to warping or twisting and is not so susceptible to contraction or expansion when it dries out or gets saturated with water. Obviously you can paint them or stain them to the shade or colour of your choice.
  • Aluminium / Aluminium Clad: Aluminium exterior doors are at the top end of the range, in terms of styling and price. They look great, last a very long time and are strong. There are literally hundreds of colours available, including timber grain effect. Aluminium clad timber doors have an engineered timber internal body with an externally applied aluminium skin.
  • Composite: A combination of GRP (Glass reinforced polymers) UPVC edging and timber cores, composite doors occupy the high end price bracket alongside aluminium. However, the finished surfaces of composite French patio doors are amazing. Great looking doors that are also super strong and secure. The lifespan is reckoned to be over 25 years on average, so you will get value for money.

How Much Do French Patio Doors Cost?

The cost of French patio doors depends on the opening size you have. Typically, supply only French patio doors without side panels will have similar pricing to sliding glass patio doors – within £100 to £150.

The cost will fluctuate if you upgrade locking mechanisms, glazing energy ratings, colours or hardware such as door furniture.

How Much do Fitted French Patio Doors Cost?
 Door size in millimeters  Basic Specification  Average Fitted Price Guide
 2 doors 900 x 2100  white, upvc double glazed – C rated  £800 to £900
 2 doors 1000 x 2100  white, upvc double glazed – C rated £1,000 to £1,200
 2 doors 1200 x 2100  rosewood, upvc double glazed – B rated £1,200 to £1,400
How Much do Supply Only French Patio Doors cost?

 1800 to 1900mm wide  White uPVC  Starting from around £600

Our conclusions

 

As with most projects of this nature, your personal preferences are going to dictate which is the best solution for you.

Having said that, those preferences need to be reflected as much as possible in the door design and function.

In our opinion, based on the above, UPVC French doors can be arguably be more secure, have more individuality in terms of appearance and be potentially more energy efficient that sliding patio doors.

Certainly for medium sized openings they “tick all the boxes” for appearance, security, longevity, functionality and price.

However, it’s your choice that matters.

What is Double Glazing?

What is Double Glazing?One of the simplest ways of understanding what double glazing is & how it works is to think of a humble sandwich. In this example the “bread” will be made from panes of glass and the “filling” will be an air gap.

The gap is maintained by using spacer bars around the outer edge of the glass. The size of the air gap can be varied from 6 to 20 millimetres.

The wider the gap, the better the energy insulation and sound reduction properties.

Sometimes the gap is filled with a heavy inert gas such as Argon to improve insulation.

So there you have it – double glazing is a glass & air sandwich!

How Much Does Double Glazing Cost?

On average, the price of a double glazed casement window in white UPVC will be approximately £300. That would be based on a size of 1 metre x 1 metre.

If you want one a little larger at 1.2m x 1.2m the price will increase to approximately £350 to £400.

What are the main factors for double glazing prices?

There are, of course, a number of different factors influencing the eventual cost of double glazing for your property.

These factors will include the size and shape of the windows you choose, the style or design, the materials used in the construction of the frames and the number of windows you order.

You can also add 2 more things to the list. Because who you buy the windows from, and where you live in the country, can also make a difference to the cost of double glazing (here are some handy tips about buying)

If we look at the basic property types:

  • To replace the old windows with new double glazed windows in a flat, maisonette or apartment, the cost is going to vary between £1,500 and £2,800.
  • For a big 3/4 bed semi, or smaller detached house, a brand new set of units would require a higher budget of somewhere around between £5,000 and £8,000. This would be for 10 to 12 white uPVC windows.

In terms of the average guide prices above, these would be what you could expect from local or regional, double glazing installers. Local independent suppliers have built up quite a good reputation over recent years of being able to offer high spec products, well fitted installations with proper customer service in terms of aftercare.

One of the most often quoted advantages of “going local”, is that local replacement window companies can offer very good pricing compared to the “Nationals”. This is likely because they don’t have to carry so much overhead costs. Costs such as big advertising campaigns and hefty commissions to sales reps (which mostly get passed onto the consumer).

When you are about to invest your hard earned savings in (or even take out financing for) replacement double glazed windows, it’s the sensible thing to do as much as you can to get the best quality products at the most competitive prices.

As we mentioned beforehand, the average quoted price from local suppliers for 10-12 windows start at around £5,000. But, if you have 4 or 5 quotes from different companies, it’s entirely possible to leverage these quotes as a negotiating tool to try to get the work done at an even lower cost.

Having installers compete with each other over prices can very often result in getting more for your money (free upgrades such as low-e glazing or gas filled sealed units). If you play your cards right, you also stand a really good chance of a decent discount on the installation cost.

Double Glazing: What are the advantages & benefits?

Before you embark on what is most certainly quite an expensive home improvement (depending on the size of the project of course), it’s prudent to consider what you are going to gain over the long term and whether that will justify the investment.

The primary benefit that most often gets mentioned is the potential money saving that can be made by fitting energy efficient replacement windows. Modern double glazing helps retain more heat, keeps out more cold, eliminates cold draughts and fights condensation.

Being able to run the central heating less often and at a lower temperature will significantly reduce your heating costs. Given that your new double glazed windows could last for 20 to 25 years, the savings can very often amount to more than it cost to buy them in the first place.

Another important feature of new double glazed windows are the safety & security elements. Just having 2 panes of glass makes them harder to break accidentally, thereby lowering the risk of personal injury. Most units are fitted with internal window beads, meaning the glass cannot be removed from outside the property. Alongside this you also have multipoint locking systems that are highly secure.

You can’t put a price on peace of mind or the safety your family. Whilst possessions can be replaced, why put them at risk with insecure windows & doors?

Did you know that some insurance companies offer reductions on their home insurance policy premiums if modern double glazed windows & doors have been fitted? Certain conditions will apply, so check your policy schedule or contact your provider to find out more.

What are the different types of double glazing?

Replacement windows are a big market in the UK. There is a really wide range of different appearance and functionality amongst the products currently on offer.

Here we will take a quick look at the main features & benefits of the most popular designs. We will also cover some examples of average prices in the market from local and regional suppliers (prices may not include fitting or taxes).

Casement Windows: White UPVC

How Much do uPVC Casement Windows Cost?Mainly due to widespread competitive pricing matched with contemporary styling, UPVC Casement windows are one of Britains’ most popular designs.

Available in both fixed or opening versions, dependent on your requirements, they can be configured to open in or out.

The typical outward opening casement allows for plenty of fresh air to circulate. They can have movement limiters fitted, such as night latches, so that you can benefit from the fresh air without having to worry about an unwanted visitor (human or animal) getting access.

In terms of function, you can have them fitted to be hinged from either side (left or right), top or bottom. Top hung versions are usually called Awning casements. Bottom hung versions are called Hopper windows.

What are UPVC Casement Windows Prices?

(All Sizes in Millimeters Height by Width)

  • 500 x 500 (non-opening)      £150-£180
  • 1000 x 500 (non-opening)    £170-£210
  • 1000 x 1000 (non-opening)  £210-£250
  • 500 x 500 (single opener)     £260-£300
  • 1000 x 500 (single opener)   £270-£350
  • 1000 x 1000 (single opener) £300-£400

French Window: White UPVC

Cheap Double GlazingOne of the more stylish and classic variation on the casement design is the French window. This design, in effect, is 2 casements fitted side by side within a single frame.

The design can come with or without a centre mullion post (where the opening sections meet in the middle). The centre posts makes the windows more secure as the frames lock on to the post instead of each other. However, the centre post can obstruct the view and additionally, this version is costlier.

Once again, they can be set up to open in or out, with outward being the more favoured. With both sides open you will benefit, not only from a great view of the outside, but also plenty of fresh air.

In general, a French window will cost quite a bit more than a standard casement version.

  • 1000 x 1000 White UPVC French Window       £500 – £550
  • 1200 x 1200 White UPVC French Window        £550 – £600

Tilt and Turn Windows:

tilt and turn windowsThis design is one that can divide opinion, but is actually quite popular and unique. Tilt and Turn windows work in a way that allows them to open in 2 completely different directions:

  1. Moving frame opens inwards on side hinges.
  2. Moving frame tilts inwards on bottom hinges.

The opening function is controlled by a single handle, dependent on which way you turn it. Moving the handle in one direction operates the tilt function, move it in another direction and the turn function is released. You cannot tilt & turn a single window at the same time.

The tilt function allows the window to “lean” backwards into the room. The amount of tilt is limited for safety reasons. This function allows for great ventilation.

Using the turn function allows the window to be opened like a regular casement. The standard turn function only allows for the window to open inwards.

The fact that both the functions only allow for inward opening is what can put off some homeowners from going for this type of design.

Sash Windows

Double Glazing Prices 2017This design is often associated with older, pre-war properties, such as Georgian or Victorian. The vertical sliding Sash window is truly an all-time classic.

The design is characterised by having 2 sections, top & bottom. The opening function of the sash window design is to slide the moving section either down or up.

Where both sections can open, they are called “double hung”. Where only the bottom section can move, they are known as “single hung”.

The standard option is for a single hung version, where the bottom section slides upwards. Due to the counterbalance system, you can slide them up as much, or as little, as needed. Can also be considered as a good means of escape in an emergency.

With the double hung version, you can open both sections at the same time.

These are quite complex to manufacture, as there needs to be a counter- weight system built into the outer frames.

This complex construction translates into quite a considerable price increase when compared to a standard casement window. The higher price of sash windows has led many homeowners to go for a lower cost option, such as false sashes, when they need to be replaced.

What are UPVC Sash Windows Prices?

(All Sizes in Millimetres Height by Width)

  • 500 x 500 White UPVC Sash Window               £500 – £600
  • 1000 x 500 White UPVC Sash Window             £600 – £700
  • 1000 x 1000 White UPVC Sash Window           £650 – £750
  • 1200 x 1200 White UPVC Sash Window            £750 – £900

Bay & Bow Windows

Both of these designs are what are known in the industry as projection windows – in other words they protrude from the property.

The major difference between the 2 styles is that bow windows have a curved appearance, whilst bay windows make use of angled sides.

bay windows

Because both of these designs protrude from the main building, you may have to consider the extra costs of “roofing & flooring” the windows.

Of the 2 designs, bay windows are going to need a proper “roof & floor”. A bay window does not usually project out as much as a bay, and therefore need less work in this area.

Bays & Bows can be built from either casement of sash window elements. Both of these types of window cost significantly more than a regular design.

There are some nice variations on the theme such as Canted & Oriel bays.

canted and oriel bay windows
What are UPVC Bow & Bay Windows Prices?

It’s very difficult to give a price guide for a bow or bay window as they are usually bespoke items built specifically to order for a particular client. Given that each job is going to be different, it means that you can’t really give an “average cost”.

The actual cost of fitting a bay or bow window, will depend greatly upon the material used and the number of panels in the design. However, as a rough guide, here are some potential costs.

Bay Window Costs

  • 3 Panel UPVC Bay Window           £1,100 – £1,200
  • 4 Panel UPVC Bay Window           £1,500 – £1,700
  • 5 Panel UPVC Bay Window           £2,000 – £2,500

Bow Window Costs

  • 3 Panel UPVC Bow Window         £1,100 – £1,300
  • 4 Panel UPVC Bow Window         £1,500 – £1,800
  • 5 Panel UPVC Bow Window         £1,800 – £3,000

Which type of double glazed window is the best?

The answer is going to be heavily influenced by personal preference and, of course, your budget. But it’s also fair to say that some double glazed windows will clearly be better for the job at hand than others.

For example, if your property & the surrounding properties are fitted with Sash windows, then it’s going to make your home “stand out like a sore thumb” if you decide to install Tilt & turn. It may even damage the desirability and resale value if you did so.

But, as a matter of appearance, convenience, availability, price competitiveness, lifespan and security, UPVC casement windows represent a really good all-round solution for many homeowners.

window energy ratings

WER: Window Energy Rating Labels

The best performing double glazing, however, is surely going to have a high Window Energy Rating (WER) such as A++, combined with a long lasting secure frame.

The high energy efficiency is achieved by adding a metal oxide coating (Low-E glazing) to the outer side of the glass, so that it “bounces” the heat back into the house.

Filling the space between the twin panes of glass in the sealed unit with a heavy gas such as Argon also improves insulation.

Did you know (according to a which.co.uk survey), that almost 50% of people who bought replacement windows did so specifically to help reduce their energy bills?

If your budget does not extend to top of the range double glazing, and you opt for a cheaper version, you need to keep in mind that C-rated windows are the minimum requirement to meet the UK building regulations.

What are the main window and frame features?

The thickness of the double glazing itself is important. Most double glazed units are between 14 to 28 millimetres thick. The wider the “air gap”, the more energy efficient.

As mentioned beforehand, the energy efficiency can be improved by adding Argon gas. Using Low-E glass and “warm edge” spacers will also raise the performance levels.

Aluminium Window Frame

Aluminium Window Frame Showing Internal Chambers

Frames come in different materials, such as UPVC, timber and Aluminium. Each with their own particular USP (unique selling point).

UPVC holds the position of being most popular due to having lower prices than hardwood and Aluminium. It’s a lot easier to maintain than timber and, of course, does not rot or need painting like timber windows do.

Hardwood windows appeal to many because it’s a natural material that does have along lifespan when looked after. Engineered timber, a useful modern alternative to hardwood, is making its presence felt in the market. This is especially true for those property owners that feel plastic or metal windows are not suited.

The use of aluminium frames is also on the increase. One particular feature of using an aluminium frame is that it can be made a lot slimmer than UPVC or timber. Slimmer frames are possible due to the natural structural strength of aluminium – you get “more glass, less window frame”.

Should you buy triple glazing?

Triple Glazed Window m

UPVC Triple Glazed Window Cross Section.

Looking at a house from the street, you really won’t be able to tell whether it’s fitted with double or triple glazing. The difference, however, becomes very apparent once you have triple glazing installed.

Triple glazing in the UK is not a big market, mainly because the UK weather (although grey & miserable a lot of the time) is not that severe. As an example, unlike Scandinavian or Nordic countries where winters can be extremely cold.

However, there is no doubt that triple glazing has measurably better energy efficiency and better sound proofing than double glazing. It can be up to 18 degrees warmer than a single glazed room and between 2 to 7 degrees warmer than a double glazed room.

Triple glazing is especially beneficial if you live in a noisy neighbourhood. The sound from the outside is deadened by the extra layer of glass combined with the second “air-gap”. In this instance, the quality of life improvement may well justify the extra purchase costs.

However, you can make double glazed windows more soundproof by just having inner and outer panes of slightly different thicknesses.

In terms of price, you will have to pay a premium for triple glazed windows, they are costlier than double glazed. This extra cost may not be offset by increased savings on your energy bills.

Quick FAQ – 5 Common Double Glazing Questions & Answers

1Do I need planning permission to fit replacement double glazed windows?

In the majority of cases, you won’t need planning permission, but you will have to get the windows certified as meeting building regulations.

If you live in a listed, or historic building, an area of outstanding natural beauty or conservation area, you should consult with your local planning as you may need permission to make any changes.

If you use a CERTASS or FENSA registered installer, they will certify your windows meet UK building regulations for you. Otherwise you have to do it yourself.

2Which double glazing company is the cheapest?

Buying replacement windows based on the best value for money within your budget is a better way to go.

Buying on lowest price alone can sometimes lead to you ending up with more problems than you started with. Don’t forget, that the supplier will have been looking for the cheapest component to make the windows.

In general terms, a well-established local business with a good track record should be able to supply your windows at lower prices than a big National brand. It’s likely that it costs less for them to do business because they don’t spend so much on salesperson commissions or high profile advertising.

There’s going to be a lot of variation in prices because each job is different. The best way to find out is to get quotes from both local & regional companies to compare prices.

Here is a quick summary of some local UPVC windows prices in the market.

  • Flat 4 or 5 windows                                £1,500 – £2,900
  • Small house 8 or 9 windows                 £3,500 – £5.000
  • 4 bed semi 10 or 12 windows                £5,000 – £7,900
  • Detached house 15 to 18 windows       £7,500 – £12,000
3How do I know when to replace my old windows?

There are definitely going to be signs that your old windows need replacing, although some may not be too obvious at first glance.

Here are a few pointers

  • Loose or broken handles & hinges: Badly fitting windows due to faulty hinges can allow wind or water to get in. Broken locks can let intruders in.
  • Frame seals failed: Rubber gaskets that keep the unit water tight, can perish; as can silicone sealant around the frames: If you can’t get repairs, then it’s time to replace.
  • Glazed unit seal fail: If the sealed units are leaking it can cause condensation and let all your heat out. Seals can be repaired, but it’s sometimes much better to replace them.
  • Visual degradation: Timber frames can rot; old fashioned aluminium frame surfaces can become pitted & scarred, poor quality uPVC can go yellow. If your windows look a mess it will lower the value of your home.

Take some time out to do a thorough check of your existing installation. Some problems caught early on can save you a lot of money later.

4Is it worth paying extra for Argon gas?

I saw a quote from one installer that priced Argon gas at around £12 per square metre. As that is about the size of an average window, if you need 10 windows then, at this rate, the cost is going to be around £120 for the whole house.

What you get is a slight increase in overall energy efficiency. More effective gases are Krypton & Xenon, but they are also costlier than Argon.

The gas is expected to leak at a rate of around 1% per year, so even long term that’s not so bad. But badly made seals can allow the gas to escape much quicker.

An alternative, if you only have the budget for 1 “upgrade” is to use Low-e glass coatings. It offers more energy efficiency than Argon, and of course, it doesn’t leak!

5What type of guarantees do I get when I buy replacement windows?

It will be unusual if your supplier does not provide at least a 10-year guarantee on the windows themselves.

However, what exactly is covered will only be revealed by the policy schedule. Which you should read properly. Frames & sealed units may have separate terms & conditions attached. Moving parts should also be covered.

Warranties on the installation work should be part of the contract, although the terms of the warranty can vary from contractor to contractor.

One other element to consider is whether the company who fits your windows will be in business long enough to honour the warranty, should there be a need to claim.

Alongside this are deposit guarantees. Your supplier should provide an insurance backed deposit guarantee (IBG) that protects your money. Choosing to deal with a GGF, FENSA, CERTASS or DGCOS member should resolve this concern as all these trade bodies insist on, or provide an IBG for their members.

double glazed installerSummary

Firstly, don’t be in a rush to part with your money, take your time to think about what you want, come up with a budget then do your best to stick to your plan.

Work with certified or accredited companies, this will allow for better consumer protection and reduce the likelihood of ending up with a “cowboy builder”.

Get a professional to survey your home and come up with a recommendation and provide written quotes.  Getting everything in writing avoids potential misunderstandings.

Don’t just get 1 quote, get at least 3 or 4. That way you can easily spot who is over or under-priced. Remember, if the deal looks too good to be true, then it probably is.

5 key features to look for when buying UPVC Windows.

If you are seriously considering buying replacement UPVC windows, then being forearmed with some “insider” knowledge can probably help you avoid ending up with some “cheap double glazing”.

The differences between good or not-so-good UPVC windows can be easily spotted if you know what to look for. So here’s our super quick guide to put you “in the know”.

1.      Window Energy Ratings (WER)

Buying UPVC Windows WER labelYour first indication of the overall thermal effectiveness of the windows will be the colourful WER Label.

Running from A to G, the WER ranks the performance. Ratings of A++ will be the most energy efficient, a rating of G is the lowest.

Since 2010, in the UK, the lowest rating accepted to meet building regulations is “C” (unless there are exceptional circumstances).

It’s likely that A++ rated products will attract a premium cost. Therefore, it can be worth bearing in mind that (In most circumstances) “B” rated UPVC windows will be perfectly adequate.

2.      What guarantees are on offer and what do they cover?

The longer the guarantee, the more confidence the manufacturer has in their product. Look for at least 10 years. The guarantee should also cover discoloration of the UPVC as well as defective products.

If you are asked to make a deposit on order, then you should only do so if an “insurance backed warranty” is on offer. There are installers that will do the work without taking an initial deposit, but still take the time to scrutinise the deal thoroughly.

Do the double glazed sealed units carry a separate warranty? How are they covered in the event of defects or premature failure?

The installation work itself should also carry a warranty. Even the best windows will be rendered useless by a bad installation job. Clarify who is responsible for what.

3.      The UPVC window frames (profiles)

There are a few things to bear in mind when it comes to the UPVC window profiles.

  • Internal beading for the glass – that prevents glass removal from the outside.
  • Chambered profiles – the more chambers, the better the energy efficiency is a fair general rule to follow. They not only allow for better insulation; the chambers can also be used to house metal reinforcing.
  • Welded Joints – more likely to prevent gaps forming as the window expands & contracts slightly during hold or cold periods. Mechanical joints can allow gaps to form over time thereby potentially allowing water or draughts to penetrate.
  • Weather seals – two types to look for. 1st are the rubber seals around the glass. Look for gaps in the corners of the window frames. Sometimes these rubber seals get stretched during installation. Over time they will then shrink back and leave a gap in the corner. 2nd is the “brush” seals that sit on the inner facings (lips / edges) of the window frames. They prevent draughts and water penetration.

4.      Window Furniture

window locksWhat we mean by this is all the “bits & pieces” such as handles / locks etc. “Moving parts” themselves may have a separate clause under the warranty which limits coverage to around 2 years only, so check this out.

  • Handles – should be fixed securely and not wobble. Better if they are also lockable (Check the warranty for coverage of defects or failure). If you don’t ask about the handles, then you are likely to get a basic version fitted as standard.
  • Hinges – whatever design is incorporated; they should be robust and fixed securely and feature stainless steel screws. Zinc coated screws will degrade or rust. If your hinges deflect, deform or de-align, this can cause leaks or condensation problems. A quick test to spot zinc screws is to use a magnet, if it does not stick to the screws they are stainless steel.
  • Interlockers – these are small blocks which are angled and fitted in a few points around the inner frame (where the window casement meets the frame when closed). Their purpose is to help align the window as it closes and keep it pulled firmly closed. Make sure interlockers are fitted securely.
  • Multi-point locks – these are the most effective and secure.

5.      The Double Glazing

Once again there are a few things to look out for. As mentioned previously, check the level of coverage under warranty.

What are the spacers made from? Spacers are the internal strips along the edge of the sealed double glazed unit. Aluminium spacers conduct heat. “Warm Edge” spacers made from composites, rubber or plastics are more thermally efficient. Go for Warm Edge spacers.

Two popular glazing options, or extras, are gas filled units (using Argon can add around £10 to £15 per square metre of glass) and to fit low-emissivity glass. Commonly referred to as “Low-e” glass.

If you are going for Argon gas filled double glazing it is very important that the seals on glazing are high quality to avoid excess leakage. Also ensure that they don’t get damaged during installation or your gas can leak out. To expect 1% or 2% leakage per year is probably the best result you can hope for.

In terms of the overall thickness of the double glazing, currently 28mm is considered the best performing. However, the thermal performance difference between a 20mm or 24mm unit and a 28mm unit may not be hugely significant. Bear that in mind when it comes to pricing.

In summary

Double glazing is a very competitive market with hundreds, if not thousands of installers across the UK. So it’s not uncommon to see a marked difference in UPVC windows prices available. Some lower prices can be achieved by compromising on one or more features that we have outlined above.

“Buyer beware” is a phrase that many would say is the most prudent approach to buying UPVC windows. However, by “being aware” you can often negotiate a really good deal from many well reputed and competent installers.

A short buyers guide to the key features of Aluminium or UPVC Windows.

Modern residential aluminium double glazed windows are not yet as popular as their UPVC counterparts. However, they are gaining popularity due to the major improvements in performance and appearance over the last few years.

If you are at the point of replacing the windows & doors in your home, just to give you a little insight, here is our summary comparison of the top 3 key features of Aluminium Vs UPVC double glazed Windows.

#1 – Price

One of the major factors influencing buyers has surely got to be the cost of buying & installing the windows. Whilst the cost of install is broadly going to be equal, the same cannot be said about the cost of the windows themselves.

Aluminium windows are costlier to buy than the equivalent UPVC product. The rough price guide below will give you some indication of the difference for the same size of unit.

This difference, on its’ own, can be enough to put off some people with a tight budget from even considering them in the first place.

If price alone is not your sole criteria for deciding, then there are other things to consider.

#2 – Appearance

Aluminium is structurally strong. This allows for very slim profiles to be used in the construction of the frames. Whereas UPVC needs internal metal reinforcing to give it the structural integrity necessary.

Having to include reinforcing bars within the frames leads to them being thicker to accommodate the internal bars. In some cases, it makes UPVC windows look quite “chunky”.

With aluminium windows you get “more glass, less frame”. Which, in our opinion, looks much more appealing and attractive.

This structural strength benefit is even more apparent for larger windows. Aluminium can span widths where UPVC just can’t do it without a support of some kind.

Something else you may not have considered are the fixing screws. On an aluminium frame they are screwed into metal, with uPVC the screws are driven into “plastic”. Metal to metal screw fixing is surely a stronger and longer lasting combination (less handles or hinges working loose over time).

Both aluminium and UPVC windows have coloured options. UPVC has about a dozen or so colours that most suppliers will have in stock. On the other hand, aluminium has a virtually unlimited range of colors available, with some suppliers claiming you can have almost any colour you want.

coloured UPVC Flush Fitting Windows

This is down to the process used for each. Coloured UPVC has a foil skin applied under heat to produce colours, aluminum frames use powder coat paints.

Both materials have the option for wood grain effect surfaces.

#3 – Lifespan & Maintenance.

In terms of how long your windows will last (and look good), Aluminium windows are reckoned to last easily for 40 to 45 years, but even the best UPVC windows are estimated to last around 25 years.

However, there have been a lot of “cheap UPVC windows” on the market that have barely lasted 10 years. Discoloration, warped frames, fittings becoming loose being just some of the regular culprits.

All things being equal on terms of the product & installation quality, you should get at least an extra 15 years of use from Aluminium windows.

In terms of maintenance, both need a minimum. Unlike timber, neither of these material rust or rot like wood, and are impervious to insect attack (woodworm / woodlice etc). Just keep them clean and lightly oil the moving parts here & there.

Our conclusions about Aluminium or UPVC Windows

If low prices are your priorities, then go for UPVC windows, even the highest quality products should less expensive than aluminium.

If you have a wider set of criteria, such as longevity, appearance and value for money. Then aluminium windows must be a serious consideration for you.

What are Faux Sash Windows? https://www.doubleglazingpriceguide.org.uk/what-are-faux-sash-windows/ Thu, 12 Sep 2019 08:00:03 +0000 https://www.doubleglazingpriceguide.org.uk/?p=1211 By opting for “faux Sash windows” or false sashes, you can potentially lower the cost of replacing your old sash windows.

How to make Sash Windows using Casement Windows

Choosing a windows style for your home when you need replacements can sometimes be a bit stressful. Especially if you have classic sash windows already fitted and have a limited budget the replace them.

So how can you balance your budget and the need to fit one of the costlier types of window style? Is it possible to combine both the value for money of casement windows and the classic appearance of a Sash?

In short, the answer is yes. By opting for “faux Sash windows” or false sashes, you can potentially lower the cost of replacing your old sash windows.

So, how are Faux Sash windows different?

Firstly, a classic sash window is made from 2 glazed sections (top & bottom). These sashes open by sliding vertically up & down.

Where only the top section opens they are called “single hung”. If both top and bottom sections open, they are called “double hung”.

Faux or false versions have the classic sash visual appearance but open like a side hung or top hung (awning) casement window or a tilt & turn window.

What are Faux Sash Windows?

Of course, under close inspection,

it will become clear that they are not true sash windows. But to be fair, from street level, the only way you would probably notice the difference is when the windows are opened.

For example, of the styles in the image above, the top halves of the windows would usually be the opening section. They will swing outwards from hinges placed at the top of the frame like a casement window. You could elect to have both sections open, but that will increase the cost.

With a tilt & turn version, the whole glazed area can be set to be a single unit, with the crossbars merely decorative. In this way the complete window can tilt inwards for ventilation or swing open from the side. For both turn or tilt function, the window will open inwards.

In terms of decorative features, the faux sash can be built to include window horns, beveled frame edges etc. Integral structural “proper” window bars can be utilized, or you can make use of inserts within the double glazed sealed units to keep costs lower.

False sash windows are available in timber or UPVC. UPVC windows can be made available in a range of around 12 colours or wood-grain effect finishes.

Timber sash windows are available using softwood, hardwood or even “engineered” wood, such as Accoya (https://www.accoya.com/).

Final thoughts

The traditionalists amongst us will surely argue that there is no substitute for a well-made, classically styled timber box sash window. However, they are considerably costlier than average casement window.

In our humble opinion, Faux sash windows make a very decent and value for money alternative option.
