Included Items: 50x Tile Backer Boards + 750 Washers
The XPS Tile Backer Board is a high-performance substrate designed for reliable tile installation, particularly in wet and humid environments. Featuring a blue, closed-cell XPS foam core that is completely free of CFCs and HCFCs, the board is coated on both sides with fiberglass mesh and a polymer-cement mortar layer. This construction creates a stable and durable surface ideal for setting tiles using the thin-bed process.
The XPS foam core is 100% waterproof and offers excellent resistance to water vapor. When seams and fastener heads are correctly sealed, the board forms part of a complete waterproof installation system. The panels meet stringent ASTM and ANSI waterproofing standards, ensuring long-term durability and dependable performance.
Lightweight yet strong, the board is easy to transport, handle, cut, and install — making it suitable for professional installers and DIY projects alike.
