Thermally Modified Softwood


Experience the next level of wood performance with Thermally Modified Softwood. Our Thermally Modified Softwood category offers a range of timber products that have undergone a specialised thermal treatment process, enhancing their durability, stability, and resistance to decay. Thermally Modified Softwood is the result of an innovative and environmentally friendly process that alters the wood's cellular structure, enhancing its natural properties. Through carefully controlled heat treatment, the timber gains improved dimensional stability and resistance to moisture, making it an ideal choice for various exterior applications.

The thermal modification process used on our softwood ensures long-lasting performance. The wood becomes less prone to warping, twisting, and splitting, while also gaining increased resistance to fungal decay and insect infestation. This makes Thermally Modified Softwood a reliable choice, even in demanding outdoor environments.
