WARMUS 20mm XPS 400 Cement coated Insulation Board for 16mm pipe

Description

WARMUS 20mm XPS 400 Cement-Coated Insulation Board for 16mm Pipe @ 150mm Centres

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.

Maximum Strength, Minimum Height

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.
