XPS Backer Board for Wet Room and Tile Projects

Cement-Coated XPS Tile Backer Board

This tile backer board combines an extruded polystyrene foam core with fiberglass mesh and a thin polymer-modified cement mortar coating on both faces. The coated surfaces form a substrate for a specified tiling assembly, while the XPS core provides an insulating layer.

Discuss board thickness, dimensions and the intended wall or floor construction when selecting a configuration. Contractors and distributors can include project quantities, packaging and private-label requirements in a quotation request.

Published Product Specifications

Request the current datasheet and relevant test reports for the supplied board. Confirm whether a value describes the foam core or the complete coated board and check the applicable test conditions.

Wet-Room and Bathroom Applications

Applications include tile substrates for bathroom walls and floors, bath enclosures and other suitably designed tiled features. Board selection is only one part of a wet-area installation: joints, fixing points, penetrations and connections must be detailed using the compatible waterproofing system and installation instructions.

A board on its own should not be treated as proof that the completed room is watertight. Confirm the required joint materials, adhesives and substrate preparation for the selected assembly.

Support and Floor-Heating Compatibility

• Specify whether the board will be used on a floor, supported wall or framed construction.
• Check thickness, fixing method and support requirements for the proposed tile finish.
• For floor heating, confirm compatibility with the heating system and all bonding or covering layers.
• For shelves, benches or enclosures, use a suitable structural detail rather than inferring capacity from the foam-core compressive value.

Prepare Your Inquiry

Provide the board size and thickness, application, required area and delivery destination. Include the intended tile finish and any documentation requirements so that the proposed board configuration can be reviewed.
