Smart Home Energy 
If you have radiators on cold external walls, this reflective foil sits behind them and bounces heat back into the room instead of heating the wall — cuts to size with scissors, fits in minutes, pays for itself in one winter.
Problem it solves
Reduces heat loss through walls behind radiators by reflecting up to 90% of radiated heat back into the room, lowering heating bills.
Who it's for
Homeowners or renters with radiators on external walls who want a low-cost way to reduce heat waste and heating bills without major works.
Why we recommend
Easy install and fast payback.
Savings
- Typical annual saving
- £20–£60/year depending on number of radiators, wall insulation quality, and heating usage
