contents The benefits of ThermoWood 4-5 Standard ThermoWood profiles 6-7 Wm. Morrisons Supermarket, Barrow-in-Furness, Cumbria Barnett s Telephone Call Centre, Southport, Lancashire Finnforest ThermoWood is produced by heat treating Finnish grown European Redwood (Red Pine) 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. 3

the benefits of ThermoWood Durability The improved durability of Finnforest 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 Finnforest 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 Finnforest ThermoWood is sourced from well managed and sustainable forests. The heat treatment process requires no chemical additives.the improved performance is achieved simply by the controlled application of heat and steam. Stability Finnforest ThermoWood is more stable than untreated softwood.the changes that occur within the timber during heat treatment make it less able to absorb or lose moisture.this restriction of moisture movement limits any potential for swelling, shrinkage or distortion of ThermoWood cladding boards. Maintenance Heat treatment removes resin from redwood timber. As a result there is no resin leakage or bleed through the surface coatings. The combined effect of this together with the improved stability can lead to a lower maintenance requirement. 5
