Ultra-High Strength Pre-Routed Insulation for 16mm Pipe (1200mm x 600mm)
The XPS 400 Highway Board is the ultimate solution for low-profile water underfloor heating installations. Engineered for maximum thermal efficiency and extreme load-bearing capacity, these 20mm boards feature pre-routed grooves spaced specifically for 16mm pipe, eliminating the need for complex manual routing.
Unlike standard insulation, the "Highway" board is cement-coated on both sides. This creates a superior bonding surface for tile adhesives and levelling compounds while significantly increasing the floor's structural rigidity.
High Compressive Strength: Rated at 400kPa, these boards are designed to withstand heavy foot traffic and furniture loads without compression, making them ideal for both residential and high-traffic commercial areas.
Rapid Response Heating: The cement coating acts as a thermal conductor, distributing heat laterally across the floor surface more quickly than standard foam boards.
Low-Profile Installation: At just 20mm thick, these boards are ideal for retrofit projects where floor build-up height is restricted.
Perfect Pipe Alignment: Pre-routed channels ensure your 16mm pipe stays at the correct centers for even heat distribution, reducing installation time by up to 50%.
