Wood
Deck of Nordic pine wood, subject to (Thermo-D) heat treatment of intense heat and water vapor. International ThermoWood Association ThermoWood has two standard treatment classes, Thermo-S (Stability) and Thermo-D (Durability) and classified as durable according to the EN 113 standard. The heat and steam treatment (without the use of chemicals) turns the lumber into a durable and stable product that is comparable to tropical hardwood.
Silva's ThermoWood is produced from the top or middle log for a high quality, consistent product, with only the centre of the log used to ensure live-intergrown knots. The market for thermally modified exterior products increased very rapidly as European consumers increasingly looked for alternatives to tropical woods from Asia, Africa and South America.
Apart from increased high durability properties the other main feature is added stability due to the reduction of equilibrium moisture content (EMC). Here at TimberClick we are pleased to be able to offer you this specialist site, serviced by Vincent Timber vanveen-nl.com Ltd, that concentrates on supplying you with Excellent Quality Western Red Cedar Products.
ThermoWood® modified Radiata pine will display approximate half the amount of dimensional change when compared with non-modified Radiata pine under the same conditions. Silva's commitment to supplying consistent and high quality timber products is reflected in our latest cladding material - ThermoWood®.
A Turkish producer, Nova Wood, also started producing of thermally modified wood and became a minor player in European markets. During the heat treatment, chemical and structural changes occur within the timber which alters and improves some of its basic characteristics.
Experience has refined our skills and know-how for producing high-quality ThermoWood®. 6 The treated wood is somewhat darkened in colour. The ThermoWood® production process uses heat, steam and water. This quality label offers the best guarantee for the quality of the various products, amongst others because they collaborate on research and quality control in order to improve the application of the products.
Thermowood is a term that describes Finnish-grown, PEFC (Pan European Forest Certification) certified pine that has been heated and dried in a controlled way up to 200 degrees C. The process improves durability and stability and makes the product suitable for external cladding.
This heat treatment also produces specific chemical changes of the wood, giving rise to a long-lasting and stable product. Thermowood cladding comes from Scandinavian softwood timber that has been heat treated. Thermowood has a material density approximately ten percent lower than Nordic pines.
Architects and builders are also learning the uses of the Thermowood product better, he added. Its colour darkens, it is more stable than normal timber in conditions of changing humidity, and its thermal insulation properties are improved. Tests have shown that the thermal conductivity of Thermowood is reduced by around 20-25% compared to untreated coniferous wood.
ThermoWood® modified Radiata pine will display approximate half the amount of dimensional change when compared with non-modified Radiata pine under the same conditions. Silva's commitment to supplying consistent and high quality timber products is reflected in our latest cladding material - ThermoWood®.
The heat treatment that improves the performance of ThermoWood uses no chemicals, which gives the added benefit that you know your deck is good for the environment. Although naturally durable, Thermwood can be finished for protection against the elements, which will keep it looking consistent on all elevations of your project.
Kebony is a product made by treating FSC or PEFC certified softwoods with furfuryl alcohol made from biological waste materials. As a principle the heat treatment process can be done on all wood species. The woods are placed in a vacuum chamber and thermally modified to make thermo wood.
