Review: Great idea. - Very good idea that seems to benefit us, very easy to cut and fit and for the price why not try it, it can only make rooms warmer.
Review: Easy to install - Have had this behind my radiators that are on outside walls for three weeks and think it is making a difference. Heating seems to be on less during cold spell, plus 'smallest room' which is part of porch projection on front of house, so three external walls, is definitely warmer. A reduced heating bill would be nice so shall see what next reading brings. Pack was sufficient for three typical sized bedroom radiators, three average living room radiators and one small toilet radiator. Easy to install, cut to size then cut slot up from bottom to allow to slide down over radiator brackets. Did not need adhesive pads supplied.

## Questions & Answers

**Q: I am assuming that these  are fireproof**
A: I wouldn't assume that they are fireproof.  But, as they're intended to be cut to size and slotted behind a central heating radiator that's A) full of water.  B) Max temperature 70C.  You can safely assume that there's no risk of them combusting.  

What you certainly shouldn't do, is put them close to a naked flame, or mount them behind an electric heater.

**Q: Are the adhesive tabs included**
A: Yes

**Q: Can this be used on Vertical radiators?**
A: By vertical do you mean that they are panelled radiators that are "flush" with the outside wall with a small gap between the wall and radiator?
If this is so the insulation is easy to install.

**Q: Does this work with electric wall heaters?**
A: I see no reason why it wouldn’t

### ⭐⭐⭐⭐⭐ A cheap and effective upgrade
*by B***T on 6 January 2026*

Now it's the cold season I'm sure this is helping. My worst room is a single brick thickness uninsulated bedroom bay wall with the radiator in the centre part. With the radiator hot the foil is warm and the untreated walls to each side very cold. The room feels slightly warmer and to prove this I used a digital thermostat that recorded constantly. As soon as the foil was installed it recorded an improvement in the minimum and maximum temperatures.
