20mm Tile Backer Boards

Nuwarm INSL8 Tile Backer Boards – Premium Insulation & Waterproof Tiling Base

Nuwarm INSL8 Tile Backer Boards are engineered for two essential purposes:

• Exceptional thermal insulation for underfloor heating systems.
• A superior waterproof construction surface for fixing wall or floor tiles.

Each board measures 1200mm x 600mm and is available in a range of thickness options to suit every installation.

Key Features

• Optimised for Underfloor Heating: Perfect for heating mats and under-tile cable systems, dramatically reducing warm-up times and energy usage.
• Superior Tile Support: Can hold even the heaviest wall tiles (with correct installation), unlike plasterboard.
• Energy Efficient: Reduces heat loss and warm-up time, cutting your energy costs significantly.
• Waterproof & Dimensionally Stable: Ideal for wetrooms, bathrooms, and kitchens — won’t warp, swell, or degrade.
• Acoustic Benefits: Helps reduce impact noise for a quieter living space.
