Ash Thermowood decking

Thermowood is produced by treating it in temperature of 185 - 220 °C. Thermo modification process is based on high temperature level and water steam. No chemicals are used. Thermo-treatment gives the wood new, useful features.The best and newest features on the outdoor products are the excellent resistance against decay and permeability, which increase the length of the use and durability. Benefits to flooring are the beautiful colour and stability. In the sauna the lack of resin, developed resistance of decay and warmth conductivity are very beneficial features.                                                              Really hot battens do not feel as hot when they are made of ThermoWood. And on the other hand the floor does not feel cold under cold circumstances on bare skin when it is made of Thermowood.

Colour and weathering

ThermoWood greys easily from the surface. To sustain the original colour and to avoid surface fractions finishing with UV- protection with Thermowood tone of colour. As cover paints all the same paints are suitable as when painting the normal wood. Oil based finishing substances absorb to Thermowood excellently and that is why they are good choice. Absorption of water based finishing substances is slower, so substances with long drying time are recommended. To restore the original color of the wood, use a professional wood brightener Saicos (nové okno) according to the technical instructions. Then treat with a suitable protective coating.

Processing Thermowood

Thermowood is slightly more fragile and dryer than normal wood, so risk of tearing has grown a bit when processing the wood in horizontal direction.
Planing of ThermoWood should be done with slower speed than planing of normal wood. Lack of resin eases the planing and grinding.
When processing Thermowood you have to acknowledge two important factors:
  • Sharp tools should be used to achieve the best result
  • The dust that generates is really dry and fine, so use of respirators is much recommended and working space should have a proper dust removal system.

Only stainless steel or other rust free fasteners need to be used when fixing Thermowood outside or in humid conditions. It is also recommended to use small oval head nails as this also helps to reduce the risk of slitting. Always pre-drill the holes in the wood for screws to prevent cracking. Avoid contact with corrosive metals objects which makes hardly removable blue-black stains on the wood.

Care and maintenance

Clean your deck regulary, keep it out of dirt, soil, sediments and pollen. This prevents the penetration of dirt macropores into the wood. The black dirt stains can occure under objects like umbrellas stands, flower pots, bowls, mats and other where water and hight moisture can stand without proper air ventilation.Therefore carry these objects time to time and ensure natural drying and ventilation. This helps to avoid creating of dark spots on the wood.
