Product Overview

• The STRUX XPS Curved Tile Backer Board is a flexible, tile-ready building panel designed for creating curved and rounded structures.
• Manufactured from HCFC-free extruded polystyrene (XPS) foam, reinforced with fiberglass mesh and polymer cement mortar layers, the board combines 100% waterproof performance, thermal insulation, and high mechanical strength.
• Factory-cut grooves at 30 mm intervals on one side allow the board to bend easily around pre-formed substructures. Once shaped, the grooves can be filled with tile adhesive to form a rigid, durable construction, providing a smooth and stable surface ready for tiling.

Key Advantages

• Flexible & Formable Pre-slit grooves allow easy bending for tight radii, semi-circular and complex curved designs.
• 100% Waterproof Closed-cell XPS core ensures zero capillary water absorption; ideal for wet areas.
• Strong Tiling Base Reinforced cement surface supports ceramic, porcelain, glass, mosaic and large-format tiles.
• Thermal Insulation Low thermal conductivity improves energy efficiency and comfort.
• Lightweight & Easy to Cut Can be cut with a utility knife; fast installation saves labor time and cost.
• Durable & Stable After fixing and adhesive filling, panels become rigid and long-lasting.

Applications

• Curved shower walls and enclosures
• Bathroom partitions and feature walls
• Steam rooms, saunas and spa areas
• Rounded benches, shelves and washstand bases
• Wet rooms and floor-level showers
• Underfloor heating insulation systems
• Interior decorative curved structures

Installation Notes

• Fix panels using S1-grade tile adhesive and/or stainless screws with washers
• 20–50 mm thickness: approx. 6–7 pcs/m²
• Recommended fixing quantity:
• Joints should be sealed using waterproof tape or a complete waterproofing system
• Boards should be installed in an offset pattern
• Grooves can be filled with adhesive after shaping to achieve rigidity
