Engineered timber is composed of flawless cuts of solid European Redwood, which are then glued, compressed and laminated together in a pattern of alternating wood grains. Through this process, a single structural member can be manufactured with no imperfections or weak spots. Furthermore, the alternating-grain pattern ensures that Engineered Timber is always pulling against itself, preventing the warping and bowing associated with solid timber and resulting in a product that, if properly maintained, will last a lifetime.
As Engineered Timber is made from finger jointed sections of solid timber, there is no need to source an entirely flawless piece of wood. There is also 25% less waste when compared with solid timber, meaning that Engineered Timber is both more sustainable and more environmentally friendly.
Solid timber is burdened by imperfections, often leading to one of two possible results: either you will receive imperfect timber with knots and/or weak points, or the manufacturer will need to source large pieces of timber that are literally flawless throughout at a premium price.
Additionally, timber naturally expands and contracts, twisting in the direction of the grain. As solid timber has one consistent grain throughout the entire cut, the entire length will twist in the same direction which can lead to warping and bowing.
There is a common misconception that hardwood is a better material for windows and doors. The logic is that as hardwood is denser, it is sturdier, and therefore better than softwood.
However, with regards to wooden windows and doors, the joinery is only required to support the weight of itself and the Double Glazed Unit. To this extent, the density of the wood is mostly irrelevant. The key factors when considering the durability of this type of wooden product are whether it will warp, how it will withstand the elements and whether it can withstand water / moisture.
As mentioned above, our FSC Certified Engineered Timber is actually more resistant to warping than solid hardwood, and thanks to our multiple layers of Teknos micro-porous paints, they will resist the elements for a lifetime if properly maintained.
Oak – Hardwood
Oak is a traditional British grown hardwood, consistently used for hundreds of years in all types of construction – from ship hulls to building support columns. Although it’s known for its incredible strength and durability, using oak as your timber of choice for window frames is essentially an aesthetic decision. As we mentioned in the previous tab:

Siberian Pine – Softwood
Pine is an extremely popular softwood to use for window frames – perfect for those who want timber windows but don’t want to spend more than they absolutely need to. Cheaper than hardwoods, it is easily sourced from sustainable forests (all our timber is FSC certified) within Europe. For the reasons we outlined above, Softwood windows tend to last just as long as Hardwood windows
Accoya® – Softwood
Accoya® is a type of wood, but you won’t find it in the wild. It is modified timber in which various manufacturing processes enable it to resist rot and stay strong over the product’s lifetime.
