Mapei Mapeheat Membrane Maxi

Underfloor Heating Uncoupling & Waterproof Membrane | Mapei UK

Professional Underfloor Heating Membrane for Tiled Floors

The Mapei Mapeheat Membrane Maxi is a lightweight uncoupling, anti-fracture and waterproofing membrane designed for use with electric underfloor heating systems. Engineered to support professional tile installations, this advanced membrane helps speed up the installation of tiled floors while improving durability and performance.

Suitable for use beneath ceramic, porcelain and natural stone tiles, the Mapeheat Membrane Maxi provides a secure base for heating cables while helping prevent cracks in the substrate from transferring through to the finished floor.

With its thin 7mm profile, this membrane is perfect for both new builds and renovation projects, allowing underfloor heating systems to be installed even when floor height is limited.

Designed for Efficient Electric Underfloor Heating

The Mapeheat Membrane Maxi forms part of the Mapei Mapeheat underfloor heating system, working alongside Mapeheat cables and thermostats to deliver consistent radiant heat beneath tiled floors.

The membrane features a polypropylene layer with specially designed reliefs that allow heating cables to sit securely within the surface. This ensures a fast, reliable installation and allows tile adhesive or smoothing compounds to be applied immediately after cable installation.

This makes it a popular choice for bathrooms, kitchens, wet rooms and open-plan living areas, where underfloor heating provides a luxurious, evenly distributed warmth.
