A good Mocca has to be really strong. 3-layer structure: - top layer: 4 mm, thermo-treated wood - middle layer made of spruce - bottom layer made of spruce The thermal treatment does not only give the floor an appealing appearance but also makes it much more stable. The heat treatment of the wood combined with the structure, means that the equilibrium moisture content is reduced by approximately 40%. This considerably reduces swelling, shrinkage & movement related to the natural forces in the wood. Admonter Mocca is four times more stable than solid floorboards. The properties of Beech, one of the most unstable wood species are tremendously improved by this treatment. Beech Mocca is even suitable for use over underfloor heating systems. The special 3 layer structure with transverse middle layer & bottom layer made of spruce, gives Admonter Mocca incredible dimensional stability. Admonter Mocca - yet another Admonter floor which you can rely on..
