Lightweight Waterproof XPS Tile Backer Board
Professional Substrate Solution for Tile Installation in Wet Areas
Our Lightweight Waterproof XPS Tile Backer Board is engineered for modern wet-room and tile installation systems. Composed of an extruded polystyrene (XPS) core laminated with alkali-resistant fiberglass mesh on both sides, it provides a rigid, dimensionally stable substrate for ceramic, porcelain, and natural stone tiles.
Designed for contractors, distributors, and building material wholesalers, this system significantly reduces labor intensity and structural dead load compared to traditional cement backer boards while maintaining high compressive strength.
Core Advantages
Ultra-Lightweight Construction (Up to 80% Lighter Than Cement)
- Reduced Dead Load: Minimizes structural weight load on wall framing.
- Ergonomic Handling: Enables fast, one-person installation, reducing labor fatigue and project turnaround time.
- Logistics Efficiency: Lower weight per square meter allows higher loading volumes per container, reducing freight costs for wholesale distribution.
Impermeable XPS Core & Eco-Friendly Performance
- Moisture Protection: Unlike gypsum-based boards, the closed-cell XPS core does not absorb water, swell, or degrade when exposed to continuous moisture.
- Mold Prevention: Eliminates moisture traps behind tiled surfaces, supporting healthier indoor air quality in humid environments.
- Green Building Compliance: Formulated with 100% recyclable, zero-formaldehyde materials, supporting sustainable construction and green building standards (such as LEED and BREEAM).
Dimensional Stability Under Thermal Fluctuations
Maintains structural integrity across temperature and humidity swings, minimizing the risk of:
- Tile cracking and grout failure
- Surface deformation
- Joint movement at substrate seams
High Compressive Strength & Tile Adhesion
- Load-Bearing Capacity: Engineered density safely supports heavy ceramic, porcelain, mosaic, and natural stone tiles when installed per industry guidelines.
- Surface Bonding: Textured, alkali-resistant fiberglass mesh provides a high-friction bonding plane for polymer-modified thin-set mortars.
Clean, Dust-Free Installation
- Can be scored and snapped or cut cleanly using standard utility knives.
- Generates significantly less airborne dust and edge waste compared to cement boards.

Typical Applications
Manufacturing, Production Capacity & Quality Control
Backed by advanced extrusion lines and robust manufacturing infrastructure, we ensure stable year-round supply capabilities for large-scale global distributors:
High-Volume Output: Large monthly production capacity ensuring on-time fulfillment for seasonal peaks and multi-container wholesale orders.
Container Loading Optimization: Scientific packaging design maximizes volumetric efficiency, allowing high square-meter volumes per 40HQ container to minimize shipping overhead.
Every production batch undergoes strict quality parameters backed by international manufacturing certifications (ISO9001) to ensure consistent installation performance:
Core Extrusion & Density Calibration: Maintaining uniform cell structure and predictable compressive performance.
Fiberglass Lamination: High-pressure thermal bonding of mesh layers to prevent delamination under stress.
Precision CNC Cutting: Ensuring strict length, width, and thickness tolerances (+/-0.5 mm) for seamless alignment.
Final Inspection: Surface flatness, edge squareness, and visual defect checks prior to export packing.
OEM & Wholesale Services
We support global building material brands, importers, and regional distributors with flexible custom manufacturing options:
Custom Dimensions & Thicknesses: Tailored to regional market standards and specific project architectural needs.
Private Labeling: Custom printed surface markings, logo integration, and branded packaging designs.
Export-Ready Packaging: Secured on export-grade wooden pallets with heavy-duty protective corner guards and shrink-wrapping to eliminate transit damage.
Mixed Container Loading: Flexible container optimization allowing various thickness combinations per shipment.
Frequently Asked Questions
Q: Does this board replace waterproof membranes?
A: While the board core is waterproof and does not absorb moisture, joints, screw penetrations, and wall corners must still be sealed with waterproof tape and sealing compound per standard wet-room installation codes.
Q: Can this board support large-format tiles?
A: Yes. When installed over stable framing with appropriate thickness (minimum 10 mm for walls) and bonded using polymer-modified thin-set mortar, it safely supports large-format porcelain and stone tiles.
Q: What are the MOQ, production lead times, and shipping terms?
A: Minimum order quantities depend on custom thickness, density requirements, and printing specifications. Standard production lead times average 15 to 25 days per full container load (FCL), supporting flexible FOB, CIF, or DDP terms.
