The WARMUS Underfloor Heating 3 Layer Multi Foil is a multi-layer foil designed to be laid directly above standard floor-grade insulation in screeded underfloor heating installations. It provides a protective covering over the insulation before the heating pipe and screed are installed.
The printed grid pattern provides a useful guide for setting out pipe runs, helping installers maintain consistent spacing across the floor area.
Designed for use above standard floor-grade insulation, not as a replacement. Install according to the product instructions and the specified floor construction.
