Torrified Wood

About Torrified Wood

Torrefaction is an artisanal technique that has been used for centuries to enhance the aesthetic and physical features of wood. Since torrefaction compares favourably with chemical treatment of wood, there is ever increasing interest in the many industrial applications for this process.


This straightforward, entirely natural process increases the durability and stability of wood, while enhancing the aesthetic value of individual wood species. This heat treatment increases the density of the wood, improves its dimensional stability and gives it rich, balanced overtones similar to the look of exotic wood species.

Torrefied wood is a totally natural product. Be the first to offer this superior product, which has all the hallmarks of a market leader. Torrefaction involves heating wood at relatively high temperatures to improve the properties of the wood without the addition of chemicals or toxic substances. The process is different from heat treatment in that it is done in an oxygen-deprived environment to prevent the wood from igniting, which means it is possible to heat the wood to temperatures of between 160°C and 245°C. At these temperatures, the molecular structure of the wood is altered, enhancing some of the wood’s physical properties, specifically its colour, dimensional stability and resistance to fungal decay. More efficient than drying, torrefaction eliminates the water and sap present in the wood, along with the adsorbed water contained in the wood cells, reducing the moisture content of wood to practically 0%.

Practically non existent moisture content
Torrefied wood has practically no (close to 0%) internal moisture and will not reabsorb moisture from the air or surface runoff since its hygroscopic properties are altered by the heating process.

Dimensional stability
Torrefied wood will not shrink, swell or warp with changing weather and moisture conditions. It is therefore ideal for precision applications such as furniture, doors and windows.

Resistance to bio degradation
Torrefied wood is resistant to fungi and molds, which mark and degrade wood, because fungi and molds require a moisture content of at least 20% to develop.

Resistance to insect pests
Because torrefaction kills the cells on which wood insects and parasites feed, torrefied wood is never attacked by pests, an important feature for the North American and European market, where termite damage is a major concern.

Chemical free treatment process
Torrefaction uses no chemicals or toxic substances. The production and use of torrefied wood is therefore perfectly safe and in compliance with the most stringent environmental and export standards. Moreover, torrefied wood unlike chemically treated wood can be safely handled, transported and processed immediately.

Treated through to the core
Unlike, chemical treatment, which protects only the surface layer of the wood, torrefaction affects the entire piece of wood through to the core. Torrefied wood can, therefore, be processed, cut or sanded, without loosing any of its properties. Cut ends remain protected, and scratches and cracks are essentially invisible.

A variety of hues and consistent colour
Torrefaction can enrich the hue and appearance of practically all species, which opens up new possibilities for many species that have never been considered esthetically pleasing.
