Most people search for 'radiator foil' — but Heatkeeper's flexible PVC reflector panels outperform foil in every way. Fitted behind your radiators, they reflect wasted heat back into the room instead of letting it disappear into the wall, cutting heating costs by an average of 20%.
Why Heatkeeper Beats Radiator Foil
- Foil flattens over time and loses effectiveness — Heatkeeper's saw-tooth profile maintains air pockets permanently
- Flexible enough to slide behind any radiator without removal, yet rigid enough to stay in place
- Fire safety tested to BS476 Part 7 — foil alternatives rarely carry this certification
Ofgem-accredited under the Carbon Emissions Reduction Target (CERT) programme and fully compliant with BS fire and safety requirements (Class 1 surface spread of flame, BS476 Part 7).
How They Work
Each panel features a patented metallised "saw-tooth" profile that works in three ways:
- Reflects Radiant Heat: Bounces heat back into the room rather than into the wall, so your boiler fires less often.
- Insulates: Creates a still air barrier between the panel and the wall, stopping heat conduction.
- Improves Airflow: The profile channels warm air away from the wall and distributes it evenly across the room, eliminating cold spots.
Key Benefits
- ~20% Average Energy Saving: Independently verified and Ofgem-accredited — real savings on your heating bills.
- Faster, More Even Heat Distribution: Warms rooms quicker and eliminates cold spots throughout.
- Reduces Wall Discolouration: Minimises scorch marks and discolouration above radiators.
- Residential & Commercial Use: Suitable for any hot water heating system.
- Strong & Durable: Made from flexible PVC with a long-lasting aluminised surface.
- Fire Safety Compliant: Class 1 surface spread of flame, tested to BS476 Part 7.

Easy Installation
- Prepare the wall: Ensure the surface behind the radiator is clean and smooth for best adhesion.
- Check the gap: Panels work best where the gap between the wall and radiator is greater than 20mm.
- Fix in place: Attach using the included double-sided tape — no drilling, no mess.
- Tight gaps (<15mm): For very tight gaps, Supagrip Panel Hangers are available separately for a tool-free fit.
- Rough surfaces: Use an additional strong adhesive for a secure bond on woodchip or textured walls.
