What makes Accoya different?

Accoya is a modified timber created by the acetylation process. This patented technology allows the timber to be weather resistant, resilient to rot and remain strong for years to come. The process removes the wood's ability to absorb water; preventing it from shrinking, swelling and decay.

This is a natural process which doesn’t add anything to the wood that isn’t already naturally occurring. This also means that no toxins are released into the environment. Accoya timber is always obtained from sustainable sources and is recyclable so is perfect for environmentally conscious customers.

Unbeatable performance

The impressive performance of Accoya matches or exceeds that of tropical hardwoods and it’s rigorously tested for quality. Naturally insulating and with a high strength to weight ratio, it makes the optimum window, door or conservatory frame.

Guaranteed for 50 years above ground and 25 in the ground or freshwater, it’s a timber that won’t let you down. Exceptionally strong and weather resistant, you won’t find a better timber species that ticks all the boxes.

Natural beauty with remarkable performance

The strength and durability of Accoya makes it ideal for coating and colour lasts two times longer than other timbers. This makes it perfect for homeowners who want to customise their new windows, doors or conservatories. The acetylation process doesn’t affect the natural aesthetic value of the timber; it will always give a perfect finish for every home.

Timber is a desirable material for many homeowner’s due to its natural beauty and traditional appearance. Period and country homes especially suit timber but Accoya products can complement any home.
