Tritherm Sticky Mat Electric Underfloor Heating System – 100W/m² & 150W/m²

The Tritherm Sticky Mat System is a fast, reliable, and easy-install electric underfloor heating solution designed for use directly beneath tiles or within a levelling compound for other floor finishes such as vinyl, carpet, timber, or laminate.
With its self-adhesive fibreglass mesh and pre-spaced 4 mm dual-core heating cable, the system installs quickly, stays perfectly flat, and ensures a smooth, snag-free tiling experience.

Easy, Clean Installation

The Sticky Mat uses a pressure-sensitive adhesive that securely binds the mat to the subfloor, preventing lifting or curling while still allowing repositioning if needed.
Ideal for regular-shaped rooms, the 500 mm wide mat can be rolled out in parallel runs for fast coverage.

Can be installed:

• Directly into tile adhesive, OR
  
• Covered with a levelling compound before applying vinyl, carpet, timber, or laminate flooring

Durable 4 mm Heating Cable

The system features a strong 4 mm dual-core cable, double-insulated with:

• Advanced fluoropolymer (FEP) inner insulation
  
• Durable PVC outer jacket

This makes it tough, safe, and easy to tile over, with long-lasting reliability.

Output Options: 100W/m² & 150W/m²

Choose the output to suit your project:

• 100W/m² — ideal for well-insulated rooms, gentle floor warming
  
• 150W/m² — perfect as a primary heat source in modern and older homes

Both options provide efficient, even heat distribution across the entire floor.

Recommended Floor Build-Up

1. Final floor finish
   
2. Tile adhesive / levelling compound
   
3. Sticky Mat heating system
   
4. Insulation backer board (highly recommended)
   
5. Flexible tile adhesive
   
6. Prepared subfloor

Using insulation boards significantly improves heat-up times and efficiency.
