Thermowood

Heat-treated wood (Thermowood) is a new kind of material with an innovative wood structure. This is achieved by heat and humidity treatment, which causes not only a higher durability of wood, but also a positive effect on other physical and mechanical properties of wood. Thermowood timber is manufactured from common wood species in special drying chambers at high temperatures. Such modified wood can be used both indoors as well as outdoors. Examples of usage: floors, ceilings, garden furniture, outdoor façades, noise barriers, sauna components, fences, patios, playgrounds, etc.

Depending on the type of wood, the length and intensity of treatment occurs due to the heat treatment of wood to a more or less significant colour changes. Wood (Thermowood) gets to dark brown hue reminiscent of hardwoods. The shading depends on the temperature, which acts on the timber. Thermowood insulating properties are better than those of conventional wood dried in standard manner in a drying chamber.

During heat-treatment, the cell structure of the wood changes so that the timber has a greater stability than normal untreated wood in the same climatic conditions of the environment. Heat changes increase durance up to 30 and more years without the use of chemical protection.

Another advantage is that the manufacturing process removes all of the resin timber. At such wood without resin it is then easier to apply surface treatment and there is no penetration of the resin to the surface through the coating. Thanks to these features heat-treated wood can reduce maintenance.
