SPECIFICATIONS & DIMENSIONS
A Wet Room Becker’s Board is a high-performance construction panel designed specifically for waterproofing and supporting tiled surfaces in wet areas such as wet rooms, shower enclosures, steam rooms, and bathrooms. It is manufactured from a dense, moisture-resistant core (commonly extruded polystyrene or cementitious fibre) and coated with a waterproof cement layer on both sides.
