Engineered Wood For Windows & Doors

Easily Workable – Long lasting & Stable

Why use Synthetic, Composite or Engineered Wood for Windows & Doors?

The primary benefits of using engineered woods for the construction of windows, doors or even a conservatory are not only that the resource itself is renewable but also that the timber is very stable and designed to virtually eliminate rotting of the timber over time.

This means that you get a Box Sash Window Product that has an environmentally neutral stance but with better performance than one made from a typical expensive hardwood – often at a lower cost.

Engineered wood is also extremely “workable” because of the way the wood-grain is aligned during lamination – you don’t get knots or defects in this kind of timber!


  • Why Use Engineered Timber?
  • Alternating grains in bonded layers – reduction in shrinking, warping & expanding
  • Stronger, longer life span and improved appearance due to absence of defect.
  • Can be produced in bigger sections that would normally require a very big old tree to create
  • Wastage can be reduced by up to 1/4th by using LSL
  • Almost unlimited variations in size for manufacturing windows, doors or conservatories.
  • Cost effective – great appearance & finish
  • Same or better performance than hardwoods

So in effect you are using a material that has properties that are extremely beneficial for this type of home improvement.

You need a window or door that is going to last a long time, that requires low maintenance, that doesn’t expand & warp every time it rains or shrink & crack every time it goes through a period of dry warm weather.
