High-Density Pre-Routed Carrier for 16mm Pipe (1200mm x 600mm)
The WARMUS 20mm XPS 400 is a premium, high-compressive strength insulation board designed to simplify the installation of water underfloor heating. Featuring pre-routed grooves for 16mm pipe, these boards serve as both a high-performance thermal barrier and a precision pipe carrier, eliminating the need for a traditional thick screed.
Engineered for durability, the WARMUS board boasts a 400kPa compressive strength rating. This makes it one of the toughest boards on the market, providing a rock-solid foundation that prevents floor movement—essential for protecting stone, porcelain, and ceramic tile finishes.
Direct-Tile Surface: The double-sided cement-polymer coating provides a high-friction surface that bonds securely to flexible tile adhesive. There is no need for specialised primers or additional overboarding.
Thermal Efficiency: The high-density extruded polystyrene (XPS) core prevents heat from escaping into the subfloor, resulting in faster warm-up and lower energy consumption.
Precision Pipe Channels: Pre-cut grooves are spaced for 16mm pipe, ensuring your heating system is laid with professional accuracy for perfectly even heat distribution.
Low-Profile Design: At just 20mm thick, this board is the ideal solution for retrofits and renovations where every millimetre of floor height counts.
