4. Life cycle assessment (LCA) LCA study of ThermoWood was carried out by Imperial college London Conclusion: ThermoWood has a potential of being a green building material if consideration is made to the production as well as the use and disposal at the end of its life cycle using best available technologies
5. Certified raw material certified raw material key factor for the members of the FTWA in Finland > 90 % of raw material for thermal modification comes from PEFC certified forests the association has members also outside Finland where also other forest certification systems are used
6. Standardization ThermoWood classification Thermo-S ( Stability ) Thermo-D ( Durability, durability class 2) CEN/TS 15679 Thermal Modified Timber - definitions and characteristics approved in 2007 national implementation in 2008
CEN/TS 15679:2007: Thermally Modified Timber Definitions and characteristics Wood at which the composition of the cell wall material and its physical properties are modified by the exposure of temperature higher than 160 C and conditions of reduced oxygen availability. The wood is altered in such way that at least some of the wood properties are permanently affected through the cross section of the timber
CEN/TS 15679:2007: Thermally Modified Timber Definitions and characteristics The principal changes on thermal modification of timber compared with untreated wood are improved dimensional stability and increased resistance to decay by wood destroying fungi, and in some cases changed colours.
7. R&D Finnish ThermoWood Association annually allocates resources for topical R&D projects
ThermoWood Concept - summary: many kinds of functions are needed for succesful commercialization of new product all parts of ThermoWood Concept are essential the Concept ensures technical and ecological quality of products sold under the trademark ThermoWood ThermoWood is now accepted building material 90000 80000 70000 60000 THERMOWOOD PRODUCTION = production capacity 63919 56279 83791 72485 m 3 50000 40000 30000 20000 18799 24605 41607 39324 34968 31146 25797 21631 10000 0 2001 2002 2003 2004 2005 2006 2007 Sold Modified
