Fit this purpose-made reflective foil behind your radiators to bounce heat back into the room instead of losing it to the wall. The roll/folded 5 m × 60 cm pack gives you around 3 m² of coverage—enough for several standard radiators—while storing neatly in a drawer.

Simple to cut and install in minutes; ideal for rented homes and quick efficiency upgrades. (Best used on radiators mounted to uninsulated external walls.)

Key features

• Folded or roll , space-saving pack — easy to handle and store.

• Improve radiator efficiency — reflects warmth back into the room and helps reduce heat loss through external walls. 

• Cut-to-size in minutes — trim with scissors to fit single or double panels.

• Low-cost upgrade — a simple DIY step that can contribute to lower heating use over winter. 

• Versatile — suitable for most water-filled central-heating radiators (not for storage heaters or electric convectors).

What’s in the pack

• 1 × roll or folded radiator reflective foil sheet — 5 m × 60 cm (≈ 3.0 m² total coverage)

(Fixing method: use double-sided tape or adhesive pads. If you prefer pads, add them to your basket.)

Sizing & coverage guide

• Small radiator (≈ 600 × 600 mm): ~0.36 m²

• Medium radiator (≈ 1000 × 600 mm): ~0.60 m²

• Large radiator (≈ 1400 × 600 mm): ~0.84 m²

Typical coverage: 3–5 radiators depending on size and cut-outs.

How to install (2–3 minutes per radiator)

1. Measure & cut foil to the radiator’s width and height.

2. Create bracket slots where needed so the foil drops behind the radiator.

3. Fix to the wall (not the radiator) with pads or strong double-sided tape—shiny face towards the room.

4. Tuck the foil neatly so it’s hidden behind the panel.

Good to know

• Most effective behind radiators on external walls—that’s where heat loss is highest. 

• Keep at least a small air gap between foil and radiator for best performance.

• Safe on painted or plastered walls; always test a small area with your chosen tape first.
