- About the Thermal Treatment Process
Thermally treated wood is suitable for a wide and varied range of applications, from saunas to balconies, fencing to decking.
The heat treatment process (within a range of 160ºC to 215ºC) applied for thermally treated wood has the effect of modifying the properties of wood. Thermal treatment consists of heating wood to temperatures exceeding its spontaneous combustion temperature with the water vapour present having a protective function.
A natural process the varying temperatures, varying treatment duration and varying drying techniques require no chemical additives and impart new properties to the treated wood.
Through the treatment applied, the timber is less prone to absorb or lose moisture, helping to restrict the potential for swelling, shrinkage or distortion of the timber. During the thermal treatment process, the wood also acquires a beautiful brown colour and its velvet-like surface is pleasant to the touch. At its best, the wood possesses nuances of antique and fine wood shades that bring warmth to any project be this for an internal or external application.
The Howarth Timber & Building Supplies thermally treated cladding range has been selected using timbers sourced only from well managed and sustainable forests to ensure that a full Chain of Custody certification can be achieved. As founder members of the Forests Forever initiative and supporters of wood for good we feel it is our responsibility to provide environmental solutions for the timber cladding market today.
