Product Description

Thermo wood is dimesionally stable, resilient and entirely ecological with higher resistance against biological pests, our facade profiles are made from pine harvested in Finland.

Processing:

Thermo wood supplied by us is made using a WTT method during which the wood is treated at 180°C.

No chemicals are used during the thermal treatment. Only a little bit of water is needed to start the process. The rest takes place thanks to a gradual increase of temperature inside of a pressurised chamber (7–9 bars). Gradual heating of the wood releases moisture and creates an environment full of steam that ensures even colouring and treatment of the wood. Thanks to this process the wood is environment friendly and doesn’t endanger surrounding fauna.

Before the actual thermal treatment, the wood is pre–dried to 12–14% of moisture content. An important part of the WTT process is that the wood is never dried out completely. On the contrary, the remaining moisture content stays at 6–8%. This is the final humidity for thermo–wood.

Modern technology controls the entire manufacturing process and thereby guaranteeing a uniform treatment of the wood. Thanks to this treatment the pine changes its original naturally light yellow tone to a light dark colouring.

The wood obtains significantly improved dimensional stability and thereby reducing the woods vulnerability to deformation respectively swelling and shrinking of the wood. Dimensional changes are reduced by up to 60%.

The wood shows increased resistance to rot and mould and also improved insulation properties.

Coat and colour:

If you opt for treating your thermo–wood decking with a coat to prevent it from naturally turning grey (occurs approx. 1 year after installation) we recommend to use OSMO Decking oil n. 010 Thermo–wood oil. OSMO Decking oil is a coat based on natural plant oils and waxes and thanks to these materials is this coat not harmful to health in any way. The pigment contained in this coat doesn‘t cause any significant change in the natural tone of the thermo–pine, on the contrary the tone gets even more enhanced and furthermore the wood is protected from the UV rays that are the main cause of the wood turning grey. Do not however put the coat on any sooner than 3 months after installation. During these 3 months the wood will naturally loose some of the substances within and it will finish stabilizing after the thermal treatment.

Wood Density:

Approx. 510 – 550 kg/m3.

We supply facade profiles from Thermo pine according to ČSN EN 14519.
