Thermo Redwood Shiplap

Product Description

Whats it good for: ThermoWood, or heat treated wood, is suitable for many purposes. In the interior, it can be used in, e.g., walls, ceilings, floors, saunas, fittings, and furniture. On the exterior, it is suitable for use in, e.g., cladding, terraces, doors, and windows. Heat treatment improves both the qualities and the appearance of the wood. The beautiful brown color gives it a stylish, almost hardwood-like look. Often that alone is a good enough reason to choose ThermoWood.   How does it work: Heat treating wood is a natural way of protecting it. It improves its rot, weather and thermal resistance, and reduces the movement of wood due to moisture. No chemicals are used in the treatment, since it is based on high temperature and water vapor. During the heat treatment, the temperature of the wood is first increased to over 160 °C, and then deceased back to the normal temperature. The treatment lasts from 1.5 to 3 days, and it is regulated with the help of hot air and water vapor. The structure of the wood changes as water and extractives, such as pitch (terpenes), all the sugars & starches are removed from it. These are the perishable parts of the timber extending its life. They are classified as Class 1 durability, so 25yrs expectancy   Is it environmentally friendly: The thermo redwood is produced by HJT-Holz Oy. The company has been granted the SKH-PEFC- COC-5217 certificate. The certificate attests that the management of the origin of the wood has been assessed and follows the international PEFC standard PEFC ST 2002:2013. The certificate covers lumber acquisitions, sales, data systems, internal control and files. On the basis of the certificate, the Finnish Forest Certification Council has granted them the right to use the PEFC mark.
