Thermowood Decking

Thermowood Decking

Overview

Due to improved insulation properties Thermowood is an excellent decking material, which balances the change of heat and cold and makes it pleasant to walk on. The decking is resin free, lightweight, easy to work and fix. It offers an elegant, durable and chemical free solution for terraces, patios and balconies.

Thermowood is produced by heat treating selected Scandinavian Redwood (Pinus sylvestris), that is conditioned in a unique continuous kilning process, heating the timber to 212° Celsius whilst protecting it with steam. This thermal process enhances the chemical and physical properties of the timber providing many benefits. In external applications (BS EN 335 Use Class 3) Thermowood meets the requirements of Durability Class 2 (BS EN 350). After thermal modification the timber becomes naturally durable making it suitable for use as cladding, decking or other outdoor applications, without the need for chemical preservatives.

In addition to natural durability, thermal modification provides other benefits. The timber darkens to an attractive deep brown making it an ideal timber for decking. The colour change is consistent throughout the thickness enabling further cutting, drilling or shaping without the need for additional preservative treatment and without affecting the durability or service life. The changes to the physical properties give Thermowood greater stability over untreated or chemically treated timber. This means that Thermowood suffers less shrinkage, swelling, cupping and distortion than ordinary wood. Our Thermowood  is recognised by the Building Research Establishment (BRE) which endorses a 30 year service life when used for decking. It is also certified with the European Standard CE mark ensuring it meets EU consumer safety, health and environmental requirements.
