New and exclusive for 2023, the ultra low profile Fastwarm® FastGrid decoupling matting is specially designed for use with 2mm Fastwarm® Cable. This innovative matting eliminates the need for thicker 4.3mm+ heating cables and reduces the amount of tile adhesive required, helping to keep floor heights lower and installation costs down.
The FastGrid system is the only decoupling mat on the market engineered specifically for 2mm heating cable, making installation faster, easier, and more affordable for both homeowners and professional installers. It’s the ideal solution for navigating awkward-shaped areas with minimal hassle.
Featuring a fleece-backed membrane, FastGrid protects floors prone to lateral movement and deflection, while its ultra low profile design minimises height impact and adhesive usage. It’s also perfectly suited for wet rooms such as bathrooms and ensuites, providing reliable decoupling in moisture-prone environments.
- Unique decoupling technology protects tiled floors and securely houses 2mm Cable.
- Quick installation designed to save time for both homeowners and installers.
- Ultra low profile reduces floor height impact and requires less adhesive.
- Modular installation allows heat to be applied only where needed.
- Thickness: 4mm
- Colour: Yellow
- Available sizes: 1m2 sheet and 15m x 1m roll.
- European compliant and CE marked for quality assurance.
- Designed for use with Fastwarm® Loose Cable systems.
- Fully approved by Ultra Tile Adhesive / Instarmac.
FastGrid takes the stress out of installing electric underfloor heating in tricky spaces and sensitive floors. Its clever design keeps your floors protected while making your heating install quicker and cleaner—turning a potentially complicated job into a straightforward, hassle-free experience.
