REDWOOD (THERMOWOOD) DECKING
Thermo D. (Redwood) Pinus sylvestris
Millworks Redwood (Thermowood) is a dimensionally stable, durable timber perfect for any outdoor decking project. Thermal modification improves the wood’s properties, giving a long and maintenance free the service life.
Using only natural methods, heat and steam, Thermowood decking is completely free from chemical additives and ideally suited to a wide range of areas.
Thermowood decking has decay resistance class 2, and is a great sustainable alternative to tropical hardwood decking such as Yellow Balau.
Consistent
Thermal modification gives Redwood (Thermowood) decking a consistent warm brown colour, which if left untreated, will weather to a silver-grey.
Versatile
Thermowood decking does not react to changes in temperature or humidity as drastically as untreated wood. Material is proven to work well in a range of different climates and areas of exposure.
Toxin-free
During the thermal modification process, resin is removed from the Thermowood decking boards. As result, the wood does not secrete resin even in high temperatures making it safe, natural place for children and animals.
Naturally Stable
Lowered equilibrium moisture content of Thermowood decking makes it dimensionally stable and the material retains its shape far better than other untreated woods.
Thermowood (Thermo D)
Selective Scandinavian Redwood is chosen for tight sound knots. Thermowood (Thermo D) where D stands for durability, has a darker brown tone. Its durability and stability are improved significantly.
In external applications BS EN 335 Use Class 3, Thermowood meets the requirements of durability BS EN 350 Class 2.
DURABILITY CLASS 2, SUITABLE FOR EXTERIOR USE (BS EN 350-2)
In the correct conditions, Redwood (Thermowood) decking will weather to a silver-grey, if left untreated.
Although naturally durable, Thermowood can be finished for protection against the elements. This will keep it looking consistent on all elevations of your project. Mill Works can advise on different options for protecting your timber.
When specified, fire retardant can be applied to Redwood (thermowood), to comply with Building Regulations. NON-COM can be applied under controlled factory conditions in a vacuum pressure timber impregnation plant.
Stainless-steel fixings should be used because natural oils in the timber have a corrosive effect on ferrous metals. Millworks recommend Millfix TX15, Face Fix decking screws for a tight, crisp finish.
