Is thermowood any good?

Is thermowood any good?

Thanks to its durability and minimal moisture content, it doesn’t warp or lose shape as much as natural timber. It instead retains its shape for many years to ensure optimum performance with very little maintenance. Thermowood is therefore a healthy and safe alternative to the commonly found pressure treated timber.

What is ThermoWood?

What is ThermoWood? Finnish grown European Redwood (Scandinavian Pine) is heat-treated to temperatures in excess of 200 degrees Centigrade creating ThermoWood ‘D’. This thermal modification process improves the wood’s properties, thereby expanding the range of applications in which it can be used.

What is ThermoWood cladding?

Thermowood cladding comes from Scandinavian softwood timber that has been heat treated. With lower moisture comes higher weather resistance, meaning that thermally treated wood can be used for outdoor purposes such as facades and exterior cladding.

Who makes ThermoWood?

Stora Enso
Stora Enso is a proud producer of genuine ThermoWood®, the thermo-treated wood produced using completely natural methods – heat and steam. The thermal treatment improves the wood’s properties, opening up a wide range of applications for use outdoors or indoors.

Does thermowood change colour?

The colour change of Thermowood® is impacted by the treatment temperature and duration. The higher the temperature, the darker the colour. The colour change is primarily the result of the degradation of lignin. Heat treatment colours the wood throughout.

Is thermowood fire resistant?

In an email to one of the block’s residents in July 2017, seen by Inside Housing, the building manager confirmed that the cladding used on the block was ThermoWood with a “D – s2, d0 fire resistance rating”. ThermoWood, according to a brochure by its manufacturer, is wood that has been heated to make it “more stable”.

Is ThermoWood fire resistant?

Does ThermoWood change colour?

Can ThermoWood be painted?

Outdoor care of thermowood Heat-treated thermowood may also be painted. The surface color can be maintained by treating the boards with a pigmented wood oil, wax, wood stain, paint or varnish with UV protection.

What colour is ThermoWood?

If left untreated, Thermowood will turn a silver-grey colour due to UV rays. The beautiful grey colour lends an elegant appearance and does not affect the wood’s resistance to decay.

Can you burn ThermoWood?

In fact, ThermoWood is 30% more fire resistant than regular wood. Combined with the charring/burnt process the boards become highly fire resistant.

Is timber cladding a fire risk?

Fire resistant timber cladding is safe, and does not pose a fire risk to low rise buildings (classified up to 3-storeys). Non-combustible cladding options exist and they maintain a stylish timber-like appearance.

How is thermal treatment used to make SLP Thermowood?

The thermal treatment of wood is an ancient and natural method for improving the durability of wood. SLP Thermowood is made with a modern high-quality thermal treatment process. Thermal treatment processes the natural features of the wood using a high temperature (185 – 215°C) and water steam. No chemicals are used in the production process.

What are the thermal benefits of Thermowood wood?

Tests have shown that the thermal conductivity of Thermowood is reduced by around 20-25% compared to untreated coniferous wood. Studies on the possible benefits of thermal modification of wood began as early as the 1930s and 1940s in Europe and USA, but the manufacturing process never reached an industrial scale.

How does lunawood Thermowood work in real life?

Material is proven to work well in different climates. As result of thermal modification, Finnish types of woods are transformed into durable, weather endurance building material. LunaThermo D has decay resistance class 2. Thermowood is produced using only natural methods, heat and steam.

What kind of paint to use on lunawood Thermowood?

Normal paints, wood oils, waxes, and varnishes can be used indoors. For saunas, paraffin oil can be used in addition to a surface treatment agent to emphasize the color of Thermowood and protect it from impurities. Lunawood recommends surface treatment for Thermowood always when the end use application, such as facade, is exposed to weather.
