Buying Double Glazed Windows & Doors in Engineered Timber

The final choice of material from which your new or replacement double glazed windows & doors are made from can have an effect on a lot of things. So it’s probably worthwhile taking the time to find out a bit more about what is available to you.

As an obvious starting point, the initial purchase price is certainly one of the prime concerns for most buyers. Surely all of us want to get the best value for money, especially true when dealing with higher priced purchases such as home improvements of this type. A full set of windows & doors for a typical “semi” can cost a few thousand pounds – not the type of money you want to waste.

Putting aside the pros & cons of using Aluminium or UPVC, timber windows are still an option for many properties. Softwood windows & Softwood entrance doors get some poor reviews due to high maintenance needs and a relatively short lifespan if they are not looked after properly.

However, for one reason or another, such as you have existing wooden sash windows that need replacing in a building that requires timber to match the style, you may be required to use timber window or maybe it’s just that you personally want to use wood. If that is the case, how about looking into engineered timbers which are now used to construct very energy efficient, secure and good looking windows in the UK.

What are Engineered Timbers?

Windows & DoorsTypically, it is made out of a few layers of wood that get compressed, laminated and then glued together so that the “wood-grain” direction alternates. The stated advantage of this timber is the absence of knots that are found in solid wood. It can also easily be worked into many different shapes & sizes whilst maintaining excellent structural strength.


  • The alternating grains helps reduce shrinking & warping
  • The wood used is already “settled” which also reduces shrinking & warping
  • Easily Painted, Stained or Varnished
  • Less instance of defects within the wood itself (knots, splitting, warping)
  • Claimed to last longer due to the lower instances of defects
  • Parts of the window or door can be made using different strength grades for situations where additional stress resistance is required
  • Produced from sustainable sources
  • Manufacturers can use up to 25% less timber to make the same product, which helps on pricing
  • The choice of length, width or depth is almost unlimited
  • Long lifespan when pre-treated such as Accoya® Acetylated wood (which can last up to 50 years rot free. https://en.wikipedia.org/wiki/Acetylated_wood)

In short, engineered timbers have excellent properties that lend themselves very well to the manufacture of double glazed windows & doors, just as good or even better than UPVC in some instances.

In terms of design choice, there are plenty of suppliers for this type of product allowing homeowners to find a product that offers both a visual and environmental “upside”
