When it comes to electric underfloor heating, professional installers are always on the lookout for solutions that save time, reduce costs, and deliver reliable results. That’s exactly why FastGrid has become the go-to choice for installers across the UK.
Developed by Fastwarm, the FastGrid decoupling matting system is the only product on the market specifically engineered for 2mm heating cable—making it faster, simpler, and smarter to install than traditional systems.
If you’re an installer looking to streamline your workflow and improve client satisfaction, here are the top five reasons to make the switch to FastGrid.
1. Ultra Low Profile (Only 4mm!)
One of FastGrid’s biggest advantages is its ultra low 4mm profile, which makes it ideal for renovations or new builds where maintaining minimal floor height is critical.
Unlike traditional systems that require bulky 4.3mm+ heating cables and more adhesive, FastGrid works with 2mm Fastwarm® Loose Cable, reducing both the overall height and the amount of materials needed.
2. Faster, Cleaner Installation
Time is money—and FastGrid is designed to save both. With its unique modular layout and flexible matting, installers can easily work around awkward areas, irregular room shapes, and fixtures without hassle.
The quick-roll system allows for a smoother install, especially when compared to manually fixing heating cables or using mats not designed for 2mm cable. Less fiddling = more jobs done in a day.
3. Less Adhesive, Lower Costs
Because of its low profile and clever design, FastGrid reduces the amount of tile adhesive required during installation. This not only cuts down on costs but also helps speed up the tiling process afterward.
Installers appreciate the reduced materials and mess—plus the time saved mixing and applying large amounts of adhesive.
4. Designed for Wet Rooms & Problem Floors
Bathrooms, ensuites, and moisture-prone areas are often tricky spots for underfloor heating installs. But FastGrid is built for the challenge.
Thanks to its fleece-backed membrane, FastGrid provides reliable decoupling in areas subject to lateral movement or deflection, protecting tiled floors from cracking or shifting.
It’s also moisture-resistant, making it ideal for wet room installations where stability and longevity are key.
5. Trusted Quality & Full System Compatibility
FastGrid is not just convenient—it’s fully compliant and industry-approved. It’s:
European compliant and CE marked
Approved by Ultra Tile Adhesive / Instarmac
Engineered to work perfectly with Fastwarm® 2mm Loose Cable
With quality assurance built in, installers can use FastGrid with confidence—knowing it meets the highest standards for both performance and safety.
