Backerboard 10mm

The Theoheat Tile Backer Board is an ideal insulation solution for use with electric underfloor heating systems. Designed to significantly reduce heat loss and lower energy costs—by up to 25%—these boards are a smart investment in energy efficiency.

Key Features:

• Lightweight & Durable: Ultra-lightweight for easy transport and handling, yet strong and robust. Easily cut to size or shaped around fixed fixtures with a craft knife.

• Thermal Efficiency: Exceptional heat insulation with a thermal conductivity of just 0.034 W/mK—ideal as a thermal barrier for underfloor heating.

• Moisture Resistant: Provides moisture protection and helps minimise subfloor movement, making tiling easier and more secure.

• Dual Fixing Options:

  • For timber subfloors: Fix mechanically using screws and washers.

  • For solid subfloors: Use a flexible tile adhesive.

• High Compression Strength: Engineered to withstand loads of up to 4 tonnes per m².

• Versatile Installation: Suitable for use on both walls and floors (ensure correct installation method is followed).

• Additional Benefits:

  • Waterproof

  • Excellent sound insulation

  • Cuts easily with a knife

  • Approved by Ultra Tile adhesive manufacturers

  • High insulation performance per m²

Product Specifications:

• Dimensions: 1200mm x 600mm (0.72m² per board)

• Thickness: 10mm

Installation Notes:
For all installations (concrete, screed, or timber), a flexible tile adhesive or Mapei eco380 must be used beneath the boards. When installing on a timber subfloor, additional mechanical fixing using screws and washers at 300mm intervals is required.
