Custom Size Waterproof XPS Backer Board

Designed for professional tile installers, distributors, and building material wholesalers, this custom-size waterproof XPS backer board provides a stable, moisture-resistant substrate for wet areas. Manufactured from a high-density extruded polystyrene (XPS) foam core with a fiberglass-mesh-reinforced cementitious surface, it eliminates the need for extra liquid waterproofing membranes on bathroom walls, shower enclosures, and commercial wet rooms.

Unlike traditional cement backer boards-which are heavy, prone to dust during cutting, and require secondary waterproofing-our XPS boards combine moisture protection, thermal insulation, and dimensional stability into a single lightweight panel backed by international quality standards (CE, ISO9001 certified).

Tailored Dimensions to Minimize Jobsite Waste
Standard-size panels often force installers into excessive on-site cutting, generating scrap material and labor overhead. We configure board dimensions directly at the production line to match your regional market or project specifications.

• Length & Width: Customized to your required dimensions.
• Thickness Range: Standard and custom profiles available from 6 mm to 30 mm (e.g., 6 mm, 10 mm, 12 mm, 20 mm, 30 mm).
• Surface & Edge Options: Cement coating with embedded alkali-resistant fiberglass mesh; square edges or customized shiplap/tongue-and-groove profiles.

Closed-Cell XPS Core for Reliable Moisture Protection
The core features a 100% closed-cell extruded polystyrene structure, yielding a very low water absorption rate. Unlike gypsum-based substrates, it will not rot, swell, or degrade when subjected to prolonged humidity.

• Application Scope: Shower walls, steam rooms, bathtub surrounds, and commercial wet areas.
• Benefit: Protects the underlying framing by stopping moisture penetration behind ceramic, porcelain, or stone tile layers.

Lightweight Construction for Reduced Logistics Costs
While heavy cement boards require two-person handling and specialized wet-saw cutting equipment, XPS boards offer high rigidity at a fraction of the weight.

• Handling: Faster manual transport across multi-story job sites and easier warehouse staging.
• Freight Efficiency: Lower deadweight per pallet reduces long-distance shipping expenses for bulk distributors.

Reinforced Surface for Superior Tile Adhesion
A stable tile substrate requires strong surface bonding to prevent delamination under heavy loads. The factory-applied polymer-modified cement coating, reinforced with high-strength fiberglass mesh, provides high tensile bond strength for ceramic, large-format porcelain, mosaic, and natural stone tiles.

Integrated Thermal Insulation
The trapped inert gas within the closed-cell foam matrix gives the material inherent thermal insulation properties.

• Thermal Conductivity (lambda): 0.029 to 0.038 W/(m·K) (varies by density and thickness).
• Application Benefit: Minimizes thermal bridging on exterior-facing bathroom walls and helps maintain energy efficiency in cold climates.

As a direct manufacturer, our facility supports full-container load (FCL) orders, private-label programs, and consistent supply chains for building material brands and regional distributors.

Production Capacity & Lead Time: Stable monthly output with a standard container lead time of 15–20 days.

Custom Specifications: Adjustments to foam density, cement coating thickness, and mesh weight based on local building code requirements.

Private Label Packaging: Customized master cartons, waterproof product labeling, and branded installation instruction inserts.

Quality Assurance: Raw material density checks, automated extrusion monitoring, and batch testing for water absorption and surface peel strength prior to export.
