Europe’s largest producer of wood floorsSlide3
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.
Comparing solid and multi-layered constructionsSlide6
The sub-floor must be flat, solid and dryThe 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
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.
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.
Tone and overall effect
Subtle variations in tone and pattern, but without knots
Dramatic graining and knotted wood
Stained, brushed, bevelled, hand scraped
Available in different sizes, colours and wood species to suit all floors.There is always a solution.
Unlike plastics and other material,
wooden floors are 100% biodegradable and can be returned to nature.Slide16
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.Slide17
lueless 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.Slide18
Glueless joints are better for the environment.Slide19
Five trees are replanted for every tree harvested.

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.Slide22
