What is Thermo-Alder?
Thermo-alder is alder wood (Alnus glutinosa) that undergoes specialized thermal modification at temperatures between 160°C and 220°C in an oxygen-free environment. This innovative heat treatment process fundamentally transforms the wood's cellular structure, resulting in a premium building material with exceptional durability and stability—without any chemical additives.
The thermo-treatment process removes organic compounds and reduces wood's ability to absorb moisture, creating a 100% natural, eco-friendly alternative to chemically treated timber. The result is a beautiful coffee-brown wood that combines aesthetic appeal with superior performance characteristics.
Key Benefits of Thermo-Alder Wood
Enhanced Durability & Longevity
Heat-treated alder offers 25+ years of service life in exterior applications and even longer in interior settings. The thermal modification process eliminates nutrients that attract fungi and insects, providing natural biological resistance without toxic preservatives.
Dimensional Stability
Thermo-alder experiences minimal swelling and shrinkage (reduced by 50-90% compared to untreated wood). This exceptional stability prevents warping, cupping, and cracking—even in extreme humidity and temperature fluctuations common in saunas and steam rooms.
Low Thermal Conductivity
Unlike many hardwoods, thermo-alder remains comfortable to touch even at high temperatures. This makes it the ideal choice for sauna benches, handles, and interior surfaces where user comfort is paramount.
Eco-Friendly & Non-Toxic
The chemical-free production process ensures thermo-alder is safe for direct skin contact, food preparation areas, and allergy-sensitive environments. No VOC emissions, no leaching, and 100% recyclable at end of life.
Aesthetic Appeal
The heat treatment process naturally darkens alder to a warm coffee-brown hue with enhanced grain visibility. The color penetrates throughout the entire board thickness, ensuring lasting beauty even after surface sanding.
