Engineered Timber vs Solid Timber
We receive a lot of phone-calls and emails, asking us why we offer Engineered Timber instead of more traditional solid timber.
There is a misconception that solid timber is superior to Engineered Timber, but we here at Core Sash Windows would like to take this opportunity to state some of the facts:
Solid timber (as in, a single, whole cut of timber) is burdened by the imperfections in the wood: knots and weak points. This gives two possible results, depending on the company providing the timber.
- The wood you receive WILL have imperfections in it. At best, these will simply be visible imperfections such as knots, whilst at worst these could be cracks or weak points in the wood. If it is the latter, over time these cracks or weak points will give in to the stress that windows are placed under (extreme temperature differences, expansion and contraction, withstanding the elements). This will noticeably reduce the service life of your windows.
- The manufacturer will need to source large pieces of timber that are literally flawless throughout. This is difficult, and as you can imagine, as you increase the size requirement of a single piece of timber (some windows can be up to 2.5metres in height!) then the abundance of appropriate flawless timber greatly decreases. This increases the cost to the consumer.
So, why use Engineered Timber?
Engineered Timber is formed of the flawless cuts from the solid timber glued and compressed together, so Engineered Timber consists entirely of the best parts of the solid timber.
Why is this an advantage?
- There are no imperfections or weak spots. Properly maintained, an Engineered Timber product will last a lifetime.
- As Engineered Timber is made from smaller pieces, there is no need to source one, whole, flawless piece of wood – this is much easier, and as a result, much cheaper for the consumer.
- The layers are glued and compressed together in alternating grains. Wood naturally expands and contracts; whole wood will twist all in the same direction and this can cause warping, whereas the layering effect ensures that Engineered Timber is always pulling against itself, thereby preventing this warping.
- There is also 25% less waste when compared with solid timber, meaning that Engineered Timber is both more sustainable, and more environmentally friendly.
