XPS insulation boards are specifically designed to provide cost-effective insulation for our underfloor heating mat systems on concrete or screeded floors. These boards offer a budget-friendly solution without compromising on performance.

Key Features:

  • Compatibility with Underfloor Heating Systems: XPS boards are suitable for use with our underfloor heating mat systems, ensuring efficient heat distribution and energy savings.
  • Insulation for Underwood Heating Systems: These boards can also be utilized as insulation for underwood heating systems, providing a cost-effective solution for heat retention in wooden floors. Available in 6mm and 10mm thicknesses, they cater to different insulation requirements.
  • Under Tile System Installation: When using XPS boards for under-tile systems, it is essential to secure the boards to the subfloor using flexible tile adhesive. This ensures stability and proper heat distribution for your underfloor heating system.
  • Coverage and Dimensions: Each board has a coverage of 0.72m² and measures 1200mm x 600mm, providing sufficient coverage for your installation.
  • Thickness Tolerance: Please note that these boards may have a thickness tolerance of +/- 1-1.5mm due to the manufacturing process.
