What is Thermodified wood?

The process of Thermodification involves heating the wood to high temperatures, which alters its cell structure and increases its dimensional stability. As a result, Thermodified timber is less prone to warping, splintering, and cracking, ensuring that your woodworking projects maintain their structural integrity over time.

Unlike untreated wood, Thermodified timber is more resistant to rot, decay, and insect damage (removing the sugary nourishment means there is nothing left for them to eat!). This makes it ideal for outdoor applications where wood is exposed to harsh weather conditions. Another significant benefit is its added strength. The treatment changes the cellular structure to create a timber which is stronger and more stable than traditional wood, reducing the chances of warping or twisting over time as it will not absorb water as much water.

Thermodified is not limited to a single woodworking application; its versatility makes it suitable for a number of projects. If you’re in the business of crafting furniture, it can be utilized to create stunning tables, chairs and cabinets that will stand the test of time, even with regular use.
