    Shrinkage and Swelling Behaviour
Shrinkage and swelling dimensions per 1% of change in moisture of timber:
Length: 0.01% to 0.02%
Radial: 0.19 %
Tangential: 0.34 %

An equilibrium moisture content of approx. 9% is to be anticipated in closed, normally ventilated rooms

Shrinkage cracks may arise due to the natural and thus unavoidable shrinkage and swelling behaviour of the timber depending on the ambient conditions

The floorboards may not be exposed to the weather at any time

Every plank should be individually fixed against sliding to prevent addition of the joint width

The shrinkage and swelling behaviour of the floorboards must be taken into account in all details of the design (joint with wall, etc.), especially when used in rooms with high humidity

    Behaviour in Fire
In line with DIN 4102 and Austrian Standard B 3800, the plank floors achieve F 30-B to F 60-B with appropriate floor structures.
