100% NATURAL
The timber is treated with heat and steam in special furnaces. This treatment causes chemical changes in the timber, creating a hard-wearing and stable product.
The composition of the sugars and resins in the timber is changed so that wood-eating insects no longer consider ThermoWood® a food source.
The process
The timber is treated with heat and steam in special kilns.. This heat treatment also produces specific chemical changes of the wood, giving rise to a long-lasting and stable product.
The composition of the sugars and resins in the timber is changed so that wood-eating insects no longer consider ThermoWood® a food source.
COMPOSITION OF TIMBER BEFORE THE TREATMENT:

CHANGES IN THE TIMBER DUE TO THE TREATMENT:
1. CELLULOSE
The crystallisation of the cellulose increases the stability and durability.
2. HEMICELLULOSE
Hemicellulose decomposes into furfural and carboxylic acids. Carboxylic acid reduces the pH value and improves durability.
3. LIGNIN
The caramelisation of lignin, caused by the heat, gives the timber a darker colour tone.
