摘要

The slab has a core made of mineral wool, mineral fiber or rock wool, and sandwiched between two self-equilibrium plates with an arborite high pressure laminate, where one of the plates is a decorative and micro perforated plate. The other plate ensures equilibrium and sealing functions, and the core has a weight of 135 kilograms per cubic meter. The core has a rabbet on its periphery for receiving a batten to maintain the slab with another slab.
