The Thermo Ash decking board is made from heat-treated ash wood. It offers exceptional durability, dimensional stability, and timeless natural beauty. It is ideal for terraces, pool surrounds, patios, and outdoor flooring where both strength and aesthetics matter.
The thermal modification process is carried out in advanced computer-controlled kilns using only steam and high temperatures up to 215°C, with no chemicals or additives.
This results in:
Durability Class 1 (the highest rating for outdoor use)
Outstanding dimensional stability – no warping or twisting
Low moisture content, preventing expansion or shrinkage
Thermo Ash is sourced from responsibly managed European and American forests.
The thermal treatment is 100% natural, producing no toxic waste or emissions. It’s a sustainable, eco-conscious alternative to tropical hardwoods and synthetic decking materials.
The wood features a rich chocolate-brown tone that naturally weathers over time into an elegant silver-grey patina, beloved in Scandinavian architecture.
To preserve the original tone, apply a protective outdoor oil once installed.
Each board maintains its unique grain pattern and warm, natural texture.
