Thermowood is a thermally modification process using steam and high heat treatment. The process takes between 24 and 48 hours, taking into account some variables such as; timber species, width and initial moisture content.
Thermowood process can be divided into 3 parts; high temperature drying, heat treatment and cooling. Thanks to the thermowood process, most of negativeness of the wood are minimized and are being abolished.
As a result of the high temperature applied to the wood, the substances which are shortening the lifecycle (glucose,citric acid,resin etc.) that exist in the inner part of the wood are resolved and the rest is crystallized. This process makes the physical properties of the timber better, improves the durability and provides an excellent colour.
As a result, JK Thermowood timber becomes stable.
The quality of the timber to be used for the Thermowood process is very important. The wood which is used during the Thermowood process is selected carefully from our own sustainable forest. The suitability of the knots, fiber structure, tree age, humidity of the wood is important to achieve the highest quality.
As a principle the heat treatment process can be done on all wood species. Wood species that JK Wood has in it’s production range are rubberwood and pine. There are plans in the near future for expanding production using other wood types.
