A flat-profile thermowood decking board for clean, modern outdoor terraces.
Thermo ash provides improved stability and durability in exterior conditions.
Technical Description
Technical Description
Material
+ Thermally Modified Ash Wood - Thermo-S
+ Durability Class: 1 (25+ years’ protection against wood decay)
Class: AB
Finish: unoiled
Swoye’s Thermowood Ash is treated using heat and steam without added chemicals. This thermal modification process increases dimensional stability by up to 65% compared to untreated wood and improves resistance to moisture and fungal decay.
With its deeper, rich tone and refined grain pattern, Thermowood Ash cladding boards are well suited for exterior wall applications. The tongue-and-groove system ensures tight board alignment, reduces visible gaps, and creates a clean, uniform facade finish.
Care Instruction
Care Instruction
1. Seal Before Use
Apply wood oil, hardwax oil, or a suitable wood sealant before first use to protect against moisture and stains. Reapply as needed depending on use and cleaning frequency.
2. Wipe Spills Immediately
Although thermowood is moisture-resistant, prolonged exposure to water or liquid can still leave marks. Wipe up spills with a dry or slightly damp cloth.
3. Use Mild Cleaning Products
Clean the surface with a soft cloth and a mild soap solution. Avoid abrasive cleaners or strong chemicals, which may damage the protective finish.
4. Maintain Finish Periodically
Depending on use, reapply your chosen wood oil every 12 months to maintain water resistance and surface durability.

Thermo Ash decking combines refined appearance with enhanced outdoor performance
Treated using only heat and steam — without chemicals — the wood is optimized for exterior environments where stability and reliability are essential.
During thermal modification, the wood’s chemical structure is permanently altered at a cellular level. This reduces hygroscopicity — the natural tendency of wood to absorb moisture — resulting in greater stability and durability outdoors. The process reduces movement caused by humidity and temperature changes, making Thermo Ash decking well suited for terraces, balconies, garden spaces, and poolside areas.
Ash is valued for its straight grain and balanced texture. After thermal treatment, it gains improved resistance to decay while maintaining a smooth, comfortable surface underfoot. Unlike composite materials, it does not retain excessive heat in summer, and unlike untreated wood, it withstands winter conditions with greater dimensional stability.
With its clean grain structure and modern appearance, Thermo Ash decking offers a sustainable alternative to tropical hardwood such as Ipe. It provides long-term durability while supporting responsible sourcing and natural material choices.
Stable. Natural. Built for everyday outdoor living.
