Casa-boards are high-performance, waterproof, extruded polystyrene boards with fibreglass mesh embedded into a polymer mortar on each side, providing extra strength and rigidity. Suitable for new-build and refurbishment projects, Casa-boards are ideal for tiling wet areas like bathroom walls, showers, and wet rooms. These boards are lightweight, easy to handle, and easily cut and shaped with a sharp knife.

Casa-boards reduce wasted heat loss into the sub-floor, bringing the flooring to optimum temperature and reducing electricity running costs. They can be bonded to the sub-floor or wall surface using Technokolla tile adhesive and do not require mechanical fixings for wooden sub-floors or plaster walls. For wood studding, only 10mm boards should be used, fixed with screws and washers. Thicker boards are suitable for designing platforms, shelves, and racks.
