The construction of structural floors or the covering of floors is another possible use for Viroc boards. It is widely used in the refurbishment of old buildings to replace traditional wooden floors, which degrade in the presence of water in the bathroom and kitchen areas and in the areas where walls are connected to the facade. It can be used as a covering and finishing of existing floors. The minimum thickness of boards used on structural floors
is 19 mm. When used as covering, without any structural function and laid on an existing surface, the recommended thickness is 12mm. When applied on floors, the loads, that the Viroc board will have to bear, must be taken into account because its resistance depends on board thickness the distance between support beams. Paint or varnish coatings with good wear resistance should be applied on Viroc boards used as flooring.
