Thermal Modification is a chemical free process that enhances an inapt wood species performance with heat and steam so it increases the durability of the timber. The high heat modifies the cell structure of the wood and makes it highly resistant to rot while greatly reducing expansion and contraction.
The process requires a purpose-built oven to ensure every piece of timber is modified to the correct specification and quality. At the end of the process the moisture content of the timber is around 7% and the properties of the timber have been permanently changed.
We import thermally modified American Ash which is a native hardwood to North America and is FSC certified.
