Thermally-Modified Timber (TMT)

Thermally-Modified Timber is the wood subjected to heat treatment in order to alter some of its qualities. The process consists of placing the wood in a special chamber, exposed to high temperatures and water vapour, thereby raising its temperature almost to the 200-degree plus combustion point.

This process causes changes in the internal structure of the wood. Some of these changes are desired, while others are the side effects of the treatment itself.

The moisture in the wood is reduced drastically and, consequently, so is its weight, while its resistance to fungi, insects and moisture increases, in addition to its conductivity and thermal insulation. Thermally modified wood is more stable and has less internal stress.
