Due to their swelling and shrinkage behaviour, wooden planks are a critical installation substrate for rigid coverings made of ceramic plates and natural stones. Old wooden floors often have irregularities, that need to be leveled before laying ceramic or stone tiles. The wooden planks must be screwed to vibration-free, load-bearing wooden beam constructions (max. 40 cm beam spacing). Sufficient rear ventilation must be ensured. In order to lay a ceramic slab or a natural stone covering on wooden planks without damage, it must be decoupled from the substrate. As a positive side effect, this also improves impact sound.
