Thermally Modified Wood

Wood treated with thermal modification has been through a non-toxic process that heats the wood to temperatures of at least 400°F, changing its structural make-up.

Why Choose Thermally Modified Wood

Durable Icon


Thermal modification stabilizes the wood, making it less likely to warp, check, bow, cup, twist, or expand and contract.

During the modification process all natural sugars are cooked out of the wood, so there's less chance of insect or mould damage.

The high heat changes the wood's colour creating a beautiful, exotic look that can be preserved with an oil-based UV sealant.

Untreated, as the wood weathers it naturally ages to a rich silver colour.
