ThermoWood® Ash decking is available in various lengths and manufactured in face fix and secret clip system decking profiles. It’s non-toxic composition means it is safe for children and pets, making it suitable for residential gardens, recreational areas, and commercial spaces.

Finished with a smooth planed surface texture that emphasises the grain pattern and makes it very comfortable under foot, and left uncoated so that over time, the rich brown will age naturally to a silver-grey appearance.

ThermoWood® Ash is a thermally modified hardwood renowned for its durability, stability, and rich colouring. Sourced exclusively from International ThermoWood® Association members, it is particularly well suited to applications where adverse weather conditions are a consideration.

Dimensional stability – ThermoWood® Ash is less likely to warp, twist or cup due to its inability to absorb or lose moisture. The low moisture content achieves a superior, smooth finish when machined.

Resin free – As a result of the thermal modification process, the timber does not secrete resin even in high temperatures making it a practical and attractive choice for long-lasting garden decks.

Certified quality – Sourced exclusively from International ThermoWood® Association members, ensuring compliance with the patented ThermoWood® Thermo-D treatment classification.

Premium appearance – ThermoWood® Ash is a top-grade timber featuring minimal knots and imperfections. After treatment, the wood takes on a consistent rich brown colour with interesting grain patterns, offering a premium finish.

Environmentally friendly – The modification process is chemical free, using only heat, steam and water.
