THERMOWOOD is a beautiful, sustainable wood material produced by using natural methods, heat and steam. Thermal modification improves the wood’s properties, thereby expanding the range of applications in which the wood can be used. THERMOWOOD is dimensionally stable, resistant to decay and resin free. It can be used inside or outdoors, in any climate.  THERMOWOOD is an non-toxic natural product which is easy to machine and install.

[rt_accordion][rt_accordion_content title=”WEATHER ENDURANCE”]Due to the breakdown of hemicellulose (sugar chains), the wood no longer contains sufficient nutrients to support fungi which cause decay (KOMO certification).
LunaThermoD-class Thermowood has decay resistance class on 2 (durable) (EN 350-2). Wood products with decay resistance classes of 1 and 2 are suitable for outdoor use without any additional treatment.

Timber in durability class 2 is suitable for exterior applications above ground without the need for further treatment.[/rt_accordion_content][rt_accordion_content title=”DIMENSIONAL STABILITY”]After thermal modification, the moisture content of the wood decreases to around 4-6 percent. The equilibrium moisture content is also permanently reduced as a result of thermal modification. The equilibrium moisture content of Thermowood is about half that of untreated wood.

As a result of this lowered equilibrium moisture content, Thermowood does not react to changes in humidity as drastically as untreated wood. In practice, this means that Thermowood is dimensionally stable and retains its shape far better than untreated wood.

During the process, steam acts as a protective gas and prevents the wood from splitting and becoming damaged during treatment.[/rt_accordion_content][rt_accordion_content title=”IMPROVED THERMAL INSULATION”]

Tests have shown that the thermal conductivity on Thermowood is reduced by around 20-25% compared with untreated coniferous wood. As a result, it’s an excellent choice of material for exterior doors, cladding, windows and saunas, to name just a few applications

[/rt_accordion_content][rt_accordion_content title=”THERMOWOOD IS RESIN-FREE”]Resin is removed from the wood during the thermal modification process. As a result, the wood does not secrete resin even in high temperatures.[/rt_accordion_content][/rt_accordion][button button_text=”Download Catalogues” button_style=”custom” font=”” button_size=”small” button_icon=”” button_align=”center” button_link=”../products-catalogues/” link_open=”_self” bg_color=”rgba(10,10,10,0.5)” text_color=”#ffffff” h_bg_color=”rgba(255,255,255,0.5)” h_text_color=”#0a0a0a” border_radius=”30″ h_border_radius=”30″ border_size=”0″ h_border_size=”0″]
