Smart Home Energy 
If you've got cold external walls or radiators that heat the plaster more than the room, this reflective foil sits behind them and bounces the heat back — DIY install, works in rentals, and pays for itself in a few months.
Problem it solves
Reduces heat loss through walls and behind radiators by reflecting up to 97% of radiant heat back into the room, cutting the energy needed to maintain comfortable temperatures.
Who it's for
Renters and homeowners looking for a low-cost, non-invasive way to improve insulation in solid-wall homes, period properties, or any space with cold external walls and inefficient radiators.
Why we recommend
Easy install and fast payback.
Savings
- Typical annual saving
- £30–£80/year depending on number of radiators insulated, wall type, and heating usage
- Payback period
- Less than 1 year
