Thermally treated wood - THERMOWOOD
Thermowood is thermally treated wood with an innovated structure achieved by thermal and humidity treatment positively affecting and improving not only its durability, but also the other physical and mechanical properties of the material.
Thermowood is made of lumber of common wood species using a patented way in special drying chambers at high temperatures.
During the thermal treatment, the cellular structure of wood is changed so the wood shows greater stability than the untreated normal wood under the same climatic environmental conditions.
The dimensional changes are halved. This phenomenon is caused in particular by reducing humidity absorption capacity by 90% in wood through its thermal treatment.
It is demonstrated by having the stable equilibrium moisture contents o 4 to 6% even despite that it is located in an environment with significantly higher humidity.
Thus there is no soaking and subsequent drying out that causes a fast destruction of untreated wood doe to the disintegration and disconnection of its internal structure.
According to the wood species, length and intensity of the treatment, more or less distinct discolouration of wood takes place due to the thermal treatment. Thermowood attains up to dark brown shade resembling hardwood species, while the resulting intensity of the shade depends upon temperature affecting the wood.
Another characteristic feature is the removal (displacement) of all resin from the wood during the treatment process. This enables its problem-free use in interior and in the operation premises with high temperature and humidity, such as wellness centres (internal pools, saunas, Finnish baths, etc.)
Thermowood has also better thermal insulation properties than the common wood dried using a standard method in chamber drying kilns.
The thermal changes increase durability to more than 30 years without the use of chemical protection!
THERMOWOOD application
Thermally treated wood may be used in both interior and exterior, e.g. for the external cladding of facades, floors, garden furniture, anti-noise barriers, sauna elements, fences and enclosures, terraces, playgrounds, etc.
Sheep wool is the product of nature with extraordinary properties. It is healthy and valuable material with excellent thermal insulation ad sound-proof parameters representing the most perfect construction and insulation material of these days.
