® THERMOWOOD SOLUTIONS FOR TIMBER CLADDING AND RAIN SCREENS
Open the catalog to page 1DURABLE AND VISUALLY STRIKING Metsä Wood ThermoWood is produced by heat treating Finnish grown European Redwood/Whitewood (Scandinavian Pine/Spruce) to temperatures in excess of 200 degrees Centigrade. During heat treatment, chemical and structural changes occur within the timber which alter and improve some of its basic characteristics. The resulting product is an altogether more durable and stable timber, an ideal material for use in exposed areas such as external wall claddings.

Open the catalog to page 3INTRODUCTION TO METSÄ WOOD THERMOWOOD® Heat treatment of wood was scientifically studied by Stamm and Hansen in the 1930s in Germany and by White in the 1940s in the United States. In the 1950s, Germans Bavendam, Runkel and Buro continued research into the subject. Kollman and Schneider published their findings in the 1960s, and Rusche and Burmester in the 1970s. More recently, research work was carried out in Finland, France and the Netherlands in the 1990s. The most comprehensive research work was conducted by VTT (Finnish State Research Center) in Finland. ThermoWood is manufactured...
Open the catalog to page 4THE THERMOWOOD® PROCESS An industrial scale chemical-free heat-treatment process for wood has been developed at VTT in co-operation with the Finnish wood product industry. The ThermoWood process is licensed to the members of the Finnish ThermoWood Association. Metsä Wood ThermoWood is available in two treatment classes: Thermo-S (Scandinavian Pine or Spruce, heat treatment 190ºC, internal use) and Thermo-D (Scandinavian Pine or Spruce, heat treatment 212ºC, internal and external use). Thermowood is fully CE marked and approved. THE THERMOWOOD PROCESS CAN BE DIVIDED INTO THREE MAIN PHASES:...

Open the catalog to page 6THE BENEFITS OF METSÄ WOOD THERMOWOOD® DURABILITY The improved durability of ThermoWood makes it an excellent material to use in the production of timber claddings and rain screens.The heat treatment process enables the use of Scandinavian Redwood in areas requiring a service life of up to 30 years without the need for a chemical preservative. ENVIRONMENT The timber used to produce ThermoWood is grown in our own Finnish forests which are fully certified under the Finnish Forestry Certification System and Pan European Forestry Certification. As such you can be sure ThermoWood is sourced from...
Open the catalog to page 7ThermoWood has improved stability when compared with normal kiln- dried Scandinavian Pine and Spruce. The internal stresses within the structure of timber are reduced when it is treated with the high temperatures of the ThermoWxxi process This reduces the potential for twist and warp. In addition there is a decrease in the equilibrium moisture content and waterpermeability There exists alinear correlation between water intake properties and the dimensional stability of the material under changing moisture conditions. Swelling and shrinkage of ThermoWood is only 50% of the corresponding...

Open the catalog to page 9KEY PROPERTIES DURABILITY SERVICE LIFE ThermoWood has improved durability due to the reduction of hemicelluloses (arabinose, galactose, xylose, mannose). These are the foodstuff for rotcausing fungi and bacteria and in the absence of nourishment they are not able to occupy ThermoWood. ThermoWood has improved stability when compared with normal kiln-dried Scandinavian Pine and Spruce. ThermoWood has high resistance to most decay fungi. ThermoWood is resistant to Longhorn beetles, Anobium punctatum and Lyctus Bruneus. Use Class 1 Above ground, protected and not exposed to direct wetting (Wood...
Open the catalog to page 10DENSITY ThermoWood density is 350 - 480kg/m3 when its moisture content is 6% (typical for RH = 65%, t = 20ºC conditions). Natural variation will occur between individual boards. Material density is approximately 10% lower than the density of Scandinavian Pine & Spruce. NAIL & SCREW HOLDING STRENGTH Nail holding strength values for wire and improved nails for ThermoWood do not differ from the values of European Redwood. However, screw holding strength is about 20% less due to the altered state of the cell wall during the ThermoWood process. THE OUTLET, BANBRIDGE SOLUTIONS FOR TIMBER CLADDING...
Open the catalog to page 11PRODUCTS – VISUAL QUALITY ThermoWood is produced from European Redwood (Pinus Sylvestris) or European Whitewood (Picea Abies). The raw material is specially selected and sawn from live knotted logs. TVOC (Total Volatile Organic Compounds) values are significantly lower than those for untreated softwoods due to the evaporation of most of the terpenes during the heat treatment process. FIRE PERFORMANCE ENVIRONMENT According to EN 13501 (SBI-test) ThermoWood is in reaction to fire class D. It is possible to treat further with fire protective treatments in order to achieve Class B under EN...
