XPS core tile backing for wet-area assemblies
This tile backer board combines an XPS foam core with fiberglass and cement-based surfaces. Discuss the board for bathroom, shower and other tiled projects where the backing and waterproofing details are specified together.
Waterproofing depends on the complete assembly. Confirm the matched sealing materials and installation instructions for joints, corners, fixings and penetrations before selecting the board.

Request the current datasheet and test conditions for the selected board thickness and size. The listed material properties are not proof of a complete waterproofing system or a load rating for a tiled wall or floor.
Define the wet-area detail
- Board selection: required dimensions, thickness and supporting substrate.
- Joints and edges: specified sealing components and wall-to-floor connections.
- Penetrations: treatment around pipes, fixings and other openings.
- Tile finish: adhesive compatibility, tile loading and surface preparation.
- Project approval: required system documentation and installation checks.
For floors, framed walls, enclosures or heated assemblies, confirm the permitted construction and support details. Do not assume that the same board thickness or fixing arrangement suits every application.
