Multi-functional waterproof backer board
XPS Backer Board is a lightweight, high-performance building board made from extruded polystyrene (XPS) foam as the core material. It is designed to provide a stable, moisture-resistant and thermally insulated substrate for tile installation and other construction applications.
The XPS core features a closed-cell structure, providing excellent resistance to water absorption and moisture penetration. Depending on the application, the board can be laminated with fiberglass mesh and polymer-modified cement mortar or other reinforced surface layers to improve its mechanical strength, dimensional stability and surface performance.
With its combination of lightweight construction, waterproofing, thermal insulation and easy installation, XPS Backer Board is widely used in bathrooms, shower areas, kitchens, walls, floors and other moisture-prone areas.

Product Characteristics
Excellent Moisture Resistance
XPS foam has a closed-cell structure and low water absorption, making XPS Backer Board suitable for areas exposed to humidity and water.
It is particularly suitable for bathrooms, shower rooms, kitchens and other wet areas.
Waterproof Construction
When used together with appropriate waterproofing systems and properly sealed joints, XPS Backer Board can provide an effective moisture-resistant substrate for wet-area construction.
Thermal Insulation
XPS provides good thermal insulation performance and helps reduce heat transfer through walls and floors.
This makes the board suitable for applications where both tile support and thermal insulation are required.
Lightweight
Compared with traditional cement-based backer boards, XPS Backer Board is lightweight and easy to transport, carry and install.
The reduced weight can also help improve handling efficiency on construction sites.
Application Scenarios
XPS Backer Board is widely used as a lightweight, moisture-resistant substrate for tile installation and wet-area construction. Typical applications include bathrooms, shower rooms, kitchens, walls, floors, wet rooms, steam rooms, saunas, countertops, niches and commercial construction projects.
