Key Features:

  • Improved Efficiency: Dramatically reduces heat-up times by up to 90% (e.g., from over 2 hours to just 20 minutes) and can lower running costs by as much as 50%.
  • Waterproof & Rot-Proof: Manufactured from water-resistant extruded polystyrene (XPS), these boards are ideal for wet rooms and bathrooms.
  • High Load-Bearing Capacity: Exceptionally strong, the boards can withstand loads of up to 30 tonnes/m², providing a stable foundation for heavy floor tiles.
  • Superior Bonding Surface: Features a 0.5mm cement-polymer coating reinforced with fiberglass mesh on both sides, allowing tiles to be fixed directly with flexible adhesive without needing a primer.
  • Versatile Application: Suitable for use on both floors and walls, with the ability to support wall tile weights of up to 62kg/m².
  • Easy to Work With: Lightweight and easy to cut or shape around fixtures using a standard utility knife or saw.
  • Soundproofing: Offers additional acoustic benefits, including an impact sound reduction of approximately 21dB.
  • Certified Quality: The boards are CE marked and conform to Building Regulations Part L for energy efficiency.

Warmup Insulation Board (Cement-Coated)

The Warmup Insulation Board is a high-performance, water-resistant tile backer board designed specifically for use with electric underfloor heating systems. Crafted from extruded polystyrene (XPS) and reinforced on both sides with a 0.5mm cement-polymer mortar and fiberglass mesh, these boards provide a robust, stable surface for tiling while maximizing energy efficiency.

These boards act as a powerful thermal barrier, preventing heat from escaping into the subfloor and reflecting it upwards into the room. This significantly reduces heat-up times by up to 90%—cutting it from over 2 hours to just 20 minutes in some cases. They are exceptionally strong, capable of withstanding loads of up to 30 tonnes per m², and are completely waterproof, making them ideal for wet rooms and bathrooms.




Key Specifications & Sizes
Boards are available in various thicknesses to suit different project needs:
  • Sizes Available: 6mm, 10mm, 20mm, 30mm, 40mm, and 50mm.
  • Dimensions: Standard board size is 1250mm (L) x 600mm (W), covering 0.75m².
  • Thermal Performance: R-values range from 0.11 (6mm) to 1.33 (50mm).

Improving heat-up times and system efficiency?

Our Underfloor Heating Insulation Boards Guide explains thickness options, floor build-up and performance benefits. You can also review full system comparisons in the UFH Systems Collection Guide, and plan installation stages in the UFH Installation Guide.

What thickness of board should I use?
We recommend a minimum of 6mm for concrete subfloors and 10mm for timber subfloors to provide adequate thermal insulation and floor stability.
Can these be used on walls?
Yes. They are excellent as internal wall insulation and tile backer boards, supporting a tile loading weight of up to 62kg/m².
Is a primer needed before tiling?
No primer is required when using these boards with underfloor heating; the cement coating provides an ideal bonding surface for flexible tile adhesive.
How do I cut the boards?
They are lightweight and can be easily cut to size or shaped around fixtures using a standard utility knife or a small saw.
