Custom Waterproof Shower Backer Board | OEM Manufacturer & Bulk Supply Specification
Our Custom Waterproof Shower Backer Board (widely searched as an XPS tile backer board and waterproof tile substrate) is a high-performance tile substrate engineered for wet-area applications such as residential bathrooms, commercial shower rooms, steam rooms, and prefabricated modular units.
Unlike traditional, heavy cement boards that absorb moisture and require supplementary waterproofing membranes, our board is built on a high-density extruded polystyrene (XPS) rigid core, laminated on both sides with a polymer-modified cement coating and alkali-resistant fiberglass mesh. This advanced multi-layer composite structure delivers a water absorption rate of <0.1%, effectively blocking moisture penetration while providing a stable, high-strength foundation for ceramic, porcelain, and natural stone tiles.
Traditional Cement Board vs. Our XPS Composite Backer Board
|
Performance Comparison |
Traditional Cement Board |
Our XPS Composite Backer Board |
|
Water Resistance |
Absorbs moisture; requires extra waterproof membrane. |
<0.1% water absorption; 100% waterproof natively. |
|
Weight Profile |
Heavy (12–15 kg/m²), causes handling fatigue. |
Lightweight (3–5 kg/m²), reducing freight and labor costs. |
|
Installation Efficiency |
Requires wet saws; messy and slow to cut. |
Easily scored and snapped with a utility knife; fast installation. |
|
Mold & Rot Risk |
High risk under prolonged humidity. |
Zero risk of rot, swelling, or internal mold growth. |
Technical Specifications & Key Advantages
Superior Moisture & Mold Resistance
- Closed-Cell Core: Prevents water vapor and moisture migration, eliminating the primary cause of substrate rot, swelling, and internal mold growth in continuously humid environments.
- Application Environments: Ideal for shower walls, bathtub surrounds, wet rooms, and commercial restrooms.
High Structural Stability & Tile Support
- Compressive Strength: Features a high compressive strength exceeding 300 kPa, preventing deflection under heavy loads.
- Large-Format Compatibility: Safely supports heavy porcelain and natural stone tiles (up to 1200 x 600 mm) without sagging or tile bond failure.
- Thermal Stability: Resistant to dimensional changes caused by temperature and humidity fluctuations, reducing the risk of grout cracking.
Lightweight Design & On-Site Efficiency
- Weight Profile: Weighs approximately 3–5 kg/m² (varying by thickness), significantly lighter than traditional cement-based boards, reducing freight expenses and handling fatigue.
- Easy Fabrication: Can be scored and snapped cleanly using a standard utility knife or cut with common woodworking tools, streamlining installation around plumbing penetrations, corners, and shower niches.
