Torrefaction is an
artisanal technique that has been used for centuries to enhance
the esthetic 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 esthetic
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

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%. |
