Thermo-treated ash is a bold, beautiful choice for outdoor decking — combining the elegance of hardwood with the resilience of modern thermal treatment.
Sustainably sourced from local French forests, it offers an excellent alternative to exotic hardwoods which are now being logged into extinction.
The high-temperature process enhances durability, weather resistance and insect attack without the use of chemicals.
With its rich colour that gradually silvers in the sun, thermo ash offers a refined yet natural finish — ideal for terraces, pool surrounds, and exposed walkways where both looks and longevity matter.
