4. Wood is a hygroscopic material striving for moisture balance. It’s also anisotropic: different swelling, shrinking and performance in three directions. A multi-layer construction reduces movement by up to 75% and is more stable in climate change than a solid construction. Multi-layered wood floors

5. Comparing solid and multi-layered constructions

7. The sub-floor must be flat, solid and dry The subfloor must not exceed ± 3 mm over a distance of 2 meters. The relative humidity (RH) must be below 75% The sub floor must be stable enough to lay on Sub floor

8. Expansion must be allowed for: A minimum working gap of 10mm is required around all perimeters including fixed points (radiator pipes etc). This is based on a calculation of 1.5mm expansion per meter width of floor e.g. a 10 meter wide floor would need expansion of 15mm. Expansion

9. An approved vapour barrier such as Tuplex should always be used. Beech and hard maple are more sensitive species. Heat should be evenly distributed over the entire surface, with max surface temperature of 27°c. Underfloor heating

14. Available in different sizes, colours and wood species to suit all floors. There is always a solution. Accessories

15. Renewable Unlike plastics and other material, wooden floors are 100% biodegradable and can be returned to nature.

16. Energy efficiency In our factory waste material from logs is converted to bio-fuel. This is used to heat our own facilities and provide energy for 20,000 homes. Waste ash is then returned to the forest as a rich fertilizer.

17. Recyclable Glueless joints enable the floor to be taken up easily – and relocated if necessary. At the end of the floors useful life it can be used to produce energy or returned to nature.

18. Glueless Glueless joints are better for the environment.

19. Replantation Five trees are replanted for every tree harvested.

20. Environmental commitments FSC/PEFC ISO 14001 EMAS NWFA ISO 9001

21. Controlled suppliers A good manufacturer will only use suppliers who hold an FSC or PEFC certificate - or who in some other way demonstrate that they operate environmentally aware timber procurement.

22. The smartest solution turned out to be green Renewable Resource efficient Solvent-free finish Recyclable Long-life Glueless Water-based stains Low emissions
