The 6mm Tile Backer Board is a strong, lightweight insulated tile backer board specially developed for use with undertile heating systems. It offers excellent thermal insulation performance while providing a durable, stable base for tile and stone floor finishes.
Constructed from an extruded polystyrene core covered on both sides by a glass fibre mesh embedded in a cementitious coating, this board delivers exceptional compressive strength, moisture resistance, and stability. It is designed to prevent downward heat loss and speed up heat-up times, reducing running costs of underfloor heating systems.
What’s Included
- Single insulation backer board, size 1200mm x 600mm
- Each board covers 0.72 m²
- Minimum order: 10 boards
- Installation recommendations included
Key Features
- 6mm thickness, suitable for low build-up insulation needs
- High compressive strength and lightweight construction
- Glass fibre mesh reinforced cementitious coating for durability
- Exceptional thermal insulation reducing heat loss under tiles
- High resistance to moisture and deformation under heavy loads
- Improves efficiency and responsiveness of underfloor heating
- Easy to cut and shape on site for precise installation
- Ideal for use on timber or concrete/screed subfloors
Benefits
- Protects and improves thermal insulation beneath tile floors
- Speeds up heat output times reducing energy consumption
- Prevents deformation under foot traffic or heavy tiles
- Durable and stable base for long-lasting floor finish quality
- Suitable for domestic, commercial, and refurbishment projects
