About THERMOPINE WOOD

Thermopine Wood (Thermally Modified Pine)

Thermopine is pine wood that has been thermally modified (heat-treated) at high temperatures (usually 180220C) in a controlled, oxygen-limited environment. The process improves durability, stability, and resistance to moisture without using chemicals.

It is commonly made from species such as Scots Pine and other softwoods.

1 Manufacturing Process (Thermal Modification)

1. High-Temperature Heating Wood is heated to 180220C.

2. Steam Protection Steam prevents burning and cracking.

3. Moisture Removal Reduces moisture content to 47%.

4. Structural Change Hemicellulose breaks down, reducing woods ability to absorb water.

5. Cooling & Conditioning Wood is stabilized to usable moisture levels.

6 Common Uses of Thermopine

Exterior Applications

• Cladding & faade panels

• Decking

• Garden fencing

• Pergolas

• Outdoor furniture

Interior Applications

• Wall paneling

• Ceiling boards

• Sauna interiors (popular use)

• Flooring (light duty)

• Decorative features

Special Use

• Sauna benches (due to low heat conductivity)

• Wet areas

• Coastal environments

7 Sizes & Forms Available

• Decking boards (1928 mm thickness)

• Cladding profiles (T&G, shiplap)

• Planed boards

• Beams & battens

• Custom-milled profiles

8 Maintenance

• Apply UV-protective oil for exterior use

• Clean annually

• Re-oil every 12 years if exposed outdoors

Without treatment, it will naturally weather to a grey patina.
