6mm XPS450 Tile Backer Board 1200mm x 600mm

The XPS450 Tile Backer Board is a waterproof insulation board with an XPS foam core, polymer cement coating and fibreglass mesh surface, designed for use as a tile backer in walls, floors and ceilings in wet and dry environments. At 6mm thickness it is primarily designed as a waterproof tile backer board, while also providing some thermal insulation with a thermal conductivity of 0.034 W/mK. The unique surface finish allows tiles to be safely and securely bonded directly to the board, and also acts as a decoupling membrane to prevent tiles and grout from cracking due to horizontal floor movement. Lightweight and easy to cut with minimal dust, and suitable for indoor and outdoor use. Supplied in 1200 x 600mm boards.

Benefits

• Fully waterproof — ideal for bathrooms, wet rooms, kitchens and other moisture-prone areas
• Acts as a decoupling membrane, preventing tiles and grout from cracking due to substrate movement
• High compressive strength of 450 kPa (40 tonnes/m²) — stable base for tiling
• Thermal conductivity 0.034 W/mK — provides thermal insulation even at 6mm
• Compatible with underfloor heating systems
• Suitable for tiling, plastering and rendering, both indoors and outdoors
• Lightweight and easy to cut with minimal dust — no specialist tools required
  

Good to know

• Dimensions: 1200 x 600mm x 6mm
• Material: XPS core with polymer cement and fibreglass mesh surface
• Can be fixed by bonding or screw fixing — washers should be used when screw fixing
• Joints should be sealed with waterproof tape prior to tiling in wet areas
• Always refer to the product datasheet and fitting instructions before installation
