Accoya wood has a range of great benefits that set it apart from many other types of timber. Here are a few of them:


An incredibly durable and long-lasting type of timber, Accoya wood has an estimated working lifespan of up to 60 years. If well looked after and maintained, this lifespan easily be exceeded. Easy to clean and maintain, Accoya timber is perfect for homeowners who don’t want the hassle that comes with maintaining other timber home improvement products.

Thermal performance

Timber provides great thermal insulation and retention. As an enhanced softwood, Accoya provides exceptional thermal performance and energy efficiency. Helping to keep heat in a home for longer, Accoya wood can contribute to reducing the energy consumption of your home and reducing the cost of your energy bills.


Thanks to the special treatment process that changes the cellular structure of the timber, Accoya wood has exceptional weatherproofing properties and even repels insects! The acetylation process changes the internal structure of the timber and fools insects into thinking that it isn’t wood. As a result they don’t eat it!
