Accoya wood’s superior dimensional stability (resistance to swelling and shrinkage) exceeds all commonly used species, including Teak, Sapele and Iroko. Accoya wood has been tested over prolonged periods in all types of weathering conditions – above ground, below ground and even in water – and has been proven to withstand even the toughest of external environments.
Accoya wood’s durability (rot resistance) is Class 1, matching and far exceeding the performance of commonly used hardwoods for windows such as oak, iroko, sapele, utile and meranti..
Every batch of Accoya wood is tested after production to ensure that its durability can be guaranteed.

Naturally insulating, you can lock in the warmth and lock down the price of your energy bills. All whilst saving time, money and hassle on maintenance. In comparison to other standard wood types for joinery, Accoya thermal conductivity is:

Accoya wood has shown improved coating lifetime performance with many types of coatings, resulting in extended maintenance intervals. The light colour of Accoya wood allows for a wide range of colour finishes. Due to its stability, Accoya wood significantly prolongs the life of filmforming coatings greatly extending maintenance regimes and enabling windows to remain looking pristine for many years. Accoya® wood is easier to coat, less preparation and sanding is required.

It is more environmentally friendly to use sustainably sourced Accoya than uPVC, aluminium and unsustainably sourced hardwood. Boasting not just a lower carbon footprint, Accoya wooden windows and doors actually help remove CO2 over their life cycle.
