XPS Tile Backer Board Waterproof Lightweight Insulation Panel for Wet Rooms

An XPS Tile Backer Board is a lightweight construction panel made from extruded polystyrene (XPS) rigid foam core with cementitious or fiberglass-reinforced surface layers. It is primarily used as a tile-ready substrate in wet and dry areas, including bathrooms, showers, kitchens, floors, and walls. The closed-cell XPS core provides excellent thermal insulation, zero water absorption, and high compressive strength, while the cement-coated surface ensures strong adhesion for ceramic tiles, porcel

Yes. XPS Tile Backer Board is inherently waterproof due to its closed-cell extruded polystyrene core, which prevents water absorption and capillary action. When combined with sealed joints and appropriate waterproof tapes or membranes, it becomes a fully waterproof system suitable for showers, steam rooms, wet rooms, and bathroom floors. Unlike gypsum-based boards, XPS boards do not swell, rot, or lose mechanical strength when exposed to moisture, making them a preferred solution for long-term d

Yes. XPS Tile Backer Board is widely used in underfloor heating systems due to its low thermal conductivity and high compressive strength. The board acts as an insulating layer, directing heat upward into the tiled surface instead of losing energy into the subfloor. Its dimensional stability under temperature fluctuations ensures that tiles remain secure without cracking, making it suitable for both electric and hydronic floor heating systems in residential and commercial buildings.
