Clay drybuilding

Clayboard heavy (LEMIX) D22/D16

Drywall board made of clay for cladding of wood and metal post structures of inner walls, facing shells, ceiling and roof surfaces. The clay building board brings lots of clay into the house, with all the positive effects for the indoor climate, especially in thermal terms. It must be cut with the hand-held circular saw. The Clayboard D 22 provides the walls with a wide drywall substructure grid of 625 mm. As supplement to this product sheet the CLAYTEC Guidelines for ecological drywalls in system apply.

Scope of application
Clayboards for cladding of wood and metal post structures in the interiors. For inner walls and facing shells DIN 4103-1, installation area 1 or 2 for ceiling and roof surfaces. On surfaces of water exposure class W0-I as per DIN 18534-1, e.g. in bathrooms (except for shower area) and household kitchens. For full-surface cladding of wood and chip boards. With reinforcing layer, substrate for YOSIMA clay designer plaster or CLAYTEC clay topcoat fine 06 with CLAYFIX clay paint.

Clay, earth, wood fibre, starch, jute fabric (one-side, back side).
