XPS TILE BACKER BOARD
XPS (Extruded Polystyrene) Tile Backer Board is a high-performance construction materials, crafted from extruded polystyrene foam with a fiber-reinforced cement coating.
Its lightweight yet rigid, easy to cut and shape properties, mold-resistant makes it ideal for wet environments, preventing structural damage from water penetration.
It also serves as an underlayment for radiant floor heating systems and provides thermal insulation for walls, roofs or floors.
Compared to traditional cement boards, it reduces structural load, simplifies installation, and ensures dimensional stability in humid conditions. Whatever for both residential and commercial projects, it serves as a reliable alternative to traditional cement boards or plywood, ensuring long-lasting even in high-humidity areas.

Core Product Advantages
-
Excellent Waterproof & Moisture Resistance: Adopts fully closed-cell XPS foam core structure with nearly zero water absorption. The double cement-coated fiberglass surface completely resists water penetration and moisture erosion, effectively preventing wall dampness, mildew, peeling, and tile falling off in bathroom and shower areas.
-
Superior Thermal Insulation Performance: XPS core features outstanding heat insulation and low thermal conductivity. It effectively reduces indoor and outdoor heat exchange, keeps indoor temperature stable, saves heating and cooling energy consumption, and is perfectly compatible with underfloor heating systems to improve heating efficiency.
-
Lightweight & High Strength: Compared with traditional cement backer boards, our XPS tile backer board is lighter in weight, easy to transport and handle, while maintaining high compression resistance and structural stability. It will not hollow, deform or crack after long-term use.
-
Easy & Fast Construction: The board can be easily cut into any size and shape with a common utility knife, supporting custom processing for shower niches, shower benches, and pipe boxing. It can be directly bonded or mechanically fixed on walls, floors and stud frames, realizing one-step wall forming.
-
Direct Tiling Surface: The rough cement-coated surface provides strong adhesion for tile adhesive. Ceramic tiles, porcelain tiles, natural stone and mosaic can be tiled directly on the board surface without additional plastering or leveling treatment.
-
Durable & Eco-friendly: Made of high-quality environmentally friendly materials, non-toxic and odorless. It features strong aging resistance, corrosion resistance and long service life, adapting to various harsh humid indoor environments.
External Wall Insulation
Most heat transfer and dissipation between indoor and outdoor spaces takes place through building walls. XPS extruded polystyrene boards efficiently stabilize indoor temperatures to achieve real winter warmth and summer coolness. Their unique structure greatly enhances wall durability. XPS boards can act as a substrate for cementitious coatings to create a smooth, uniform base for wall finishes.
The inverted construction method places the XPS extruded polystyrene board above the waterproof membrane. This protects the waterproof membrane from temperature fluctuations and mechanical damage, providing effective long-term protection. Inverted roof assemblies feature a simple structure, extended service life and remarkable advantages. In addition, during roof renovation, the system can be directly installed over the existing old roof.
Details of Inverted Construction Method :
After roof capping, level the substrate surface appropriately.
(For small roof areas, no grouting is required between boards. For large roof areas, apply packing tape along board joints. This effectively prevents cracks along the board joints in the protective layer after the cement mortar hardens.)
Carry out roof waterproofing work. XPS extruded polystyrene boards are compatible with all construction methods and waterproofing materials. Verify that the waterproof membrane has fully cured before board installation.
Once the waterproof membrane passes inspection, start laying XPS extruded polystyrene boards. XPS boards have no expansion property, so expansion joints are generally not required. Cut XPS boards to fit around roof penetrations before installation. Normally, no adhesive bonding is needed for XPS boards. Asphalt can be used for bonding if required. Note that asphalt contains toluene. Allow the toluene to evaporate completely before placing XPS boards after asphalt application.
Pour the protective layer. Protective layers fall into two categories: accessible roofs and non-accessible roofs. Accessible roofs usually adopt cement mortar reinforced with steel bars. Non-accessible roofs mostly use dry-laid pebbles or artificial turf.

Installation Guidelines
XPS Tile Backer Board supports two standard installation methods (bonding fixing and mechanical fixing), suitable for different base wall conditions. Strict joint sealing treatment is required to ensure overall waterproof performance.
Base Requirement
The installation base (concrete wall, brick wall, wooden or steel stud frame, cement floor) must be clean, dry, flat, firm and free of dust and loose layers.
Two Installation Methods
Method 1: Adhesive Bonding (Most Popular)
Apply uniform flexible C2 grade cement-based tile adhesive on the base or board surface with a notched trowel, then press and paste the backer board firmly on the wall or floor. This method is widely used for new decoration and old house renovation projects.
Method 2: Mechanical Fixing
For hollow stud frame walls, use special waterproof screws with gaskets to fix the board. Screw heads need to be sunk slightly below the board surface without damaging the board core structure.
Key Waterproof Sealing Steps
The board itself is 100% waterproof, but gaps are the main leakage risks. All board joints, internal and external corners, screw holes, and pipe cut-outs must be fully sealed with professional waterproof joint tape and waterproof sealant. After the sealing layer is completely cured, tile construction can be carried out.
Tiling Instruction
Use flexible tile adhesive for thin-layer tiling. Do not use ordinary cement mortar to avoid insufficient adhesion and tile falling off.
