Application

Carrier element for laying tiles, slabs and natural stone floor coverings using the thin-bed method.

Adhesive surface for applying plaster, tile adhesive and other materials.

Moisture protection.

Effective heat insulation.

Design element.

Composite sealing with tile and slab coverings of load class A and B (directly loaded walls and floors in rooms in which tap or cleaning water is used very frequently or for long periods, walls and floors of indoor and outdoor pools that are filled with water with the properties of drinking water).

CE Marked.

Description

Composite board manufactured from extruded polystyrene (XPS) rigid foam, glass-fibre reinforced on both sides and coated with a polymer-modified cement. wedi building boards can be fitted on almost any surface; they are waterproof, heat-insulating, versatile, lightweight, dimensionally stable and quick to process and are approved for interior use in rooms at a normal temperature.
