Thermo pine

Origin	Europe, native pine stands
Raw density	approx. 400-500 kg/m³ (varies slightly depending on thermal treatment)
Durability class	Class 2-3 (increased by heat treatment compared to untreated pine)
Radial shrinkage	reduced compared to untreated pine (depending on thermal process)
Tangential shrinkage	also noticeably reduced compared to untreated pine
Wood color	warm yellow to golden brown to medium dark brown; graying possible without care
Wood structure	fine-grained, typical softwood structure; more homogeneous after treatment

Origin and character of the wood

Thermopine uses native pines – frequently grown, established stands in Central Europe. Treatment under heat and controlled conditions specifically changes the properties of the wood: Moisture is reduced, the tendency to shrink and swell decreases, and wood can become more weather-resistant. At the same time Pine remains a soft coniferous wood – thermally modified, but in its fundamental material nature it cannot be equated with hardwoods.

Thermal process: Effect – but with compromises

The heat treatment improves durability and dimensional stability – thermal pine can then be classified in durability class 2-3. This increases resistance to weathering, fungi and moisture. On the other hand, the process changes the cell structure: the wood can become more brittle, mechanical strength and elasticity suffer as a result. Experience reports show that thermally modified softwood can show signs of wear or deformation relatively quickly compared to hardwood, especially when subjected to point forces or heavy loads.

Sustainability with a critical eye

Thermopine scores with local raw materials and the absence of chemicals. However, the energy required for thermal treatment remains a sustainability factor: depending on the process, ecological gains can be offset by high energy consumption. In addition, pine, even when modified, is a comparatively soft wood, wood that requires carethat can wear out more quickly than hardwoods when used intensively or exposed to moisture outdoors. Anyone using thermal pine out of environmental and cost awareness should remain realistic: The ecological advantage is conditional, not automatic.
