Wedi 2500mm x 600mm x 4mm Building Board consists of a blue core made from extruded polystyrene rigid foam. The rigid foam is reinforced with glass fibre (with alkali-resistant finish) on both sides and coated with a polymer-modified cement. Wedi building boards can be fitted on almost any surface, and they are waterproof, heat-insulating, versatile, lightweight, and dimensionally stable and quick to process.
