Plasterboard walls generally consist of a load-bearing framework of sheet metal profiles (C-profiles), onto which plasterboard sheets are screwed on both sides. The cavity is usually filled with mineral wool to improve sound insulation.
WALL CLADDING (VENTILATED FACADE)
If plasterboard sheets are mounted on a substructure on a wall made of another material, it is called a cladding. Claddings offer the possibility to mount additional layers (insulation) or installations on a wall first and then to cover them with the plasterboard sheets. Claddings are often used for sound insulation.
