Accoya®

Here at Redwood Joinery, we are passionate advocates for Accoya®. As an officially Accoya® Certified Joinery Manufacturer since 2014, we have been crafting high-performance, bespoke timber windows and doors from our Somerset workshop for over a decade.

Why Choose Accoya® for Your Windows & Doors?

The simple answer is exceptional stability and unmatched durability. When we build with Accoya®, we know the finished product will perform flawlessly season after season, year after year, for decades.

Because Accoya® timber naturally resists movement, swelling, and shrinkage, applied finishes stay intact far longer without cracking or peeling—resulting in an incredibly low-maintenance finish. It is simply the ultimate timber choice for high-end external joinery, and if it wasn't the best on the market, we wouldn't use it.

So what's the secret?

Accoya is an ultra-high performance product, made from fast-growing and sustainable softwood, which is then treated by a natural process called acetylation. Put simply, this process changes the way that wood reacts with water, putting a stop to absorption. This removes the root cause of swelling, shrinking and warping, meaning that it performs like the finest hardwoods without any of the associated drawbacks.

Sustainability, Versatility and Durability

All Accoya comes from FSC certified forests, it is 100% non-toxic and 100% recyclable. It is thus environmentally friendly, but that would mean nothing if it wasn't also versatile and durable. It is easy to machine, it retains its strength and density, and it takes a finish beautifully. It is suitable for countless types of joinery, and it lasts and lasts.
