Accoya timber

accoya sustainable timber Imagine a consistently available solid wood that is sourced from fastgrowing sustainable forests, has zero toxicity and provides dimensional stability and durability that exceeds even the best tropical hardwoods.

Imagine a wood that can replace increasingly scare tropical hardwoods, toxic-treated woods and less sustainable materials in new and existing outdoor applications. Imagine a wood that will act as a better carbon sink during its extended life span and can be safely recycled at the end.

Such a wood exists. It is Accoya® wood, a remarkable ‘new wood species’ that allows you to use wood, without compromise.

Acetyl groups, which are simply comprised of oxygen, hydrogen and carbon, are already naturally present in all wood species – as well as in humans and other mammals. This means that the manufacturing process adds nothing to the wood that does not already naturally occur within it.

The end product, Accoya® wood, does not add toxins to the environment and the only by-products are a small amount of valuable fertilizer and acetic acid, which can be reused. The effect of altering the wood’s chemical structure, as opposed to merely altering its chemical content, is essentially to create a “new species” of wood. By contrast, other typical treatments merely insert chemicals (such as oils, ammonia or metal compounds) or add plastics to the wood.

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 the toughest of external environments. Not only is its durability proven, but it has also been shown to retain its appearance, requiring much less frequent maintenance than other wood species
