ThermaWrap Radiator Reflective Foil Insulation 500mm x 4m is rated 4.1 out of 5 by 89.
Rated 5 out of 5 by from Radiator foil Radiator foil does what it says easy to use good value
Date published: 2023-03-15
Rated 5 out of 5 by from Thin foil layer but strong Does what it's supposed to and nice thin layer so does not fall off like the foam backed stuff. I fitted it to the wall before fitting the new radiators so was easy. I'm pleased. Could possibly be fiddly to retro fit behind existing rads.

Rated 4 out of 5 by from Decent enough. Seems to be a good product. Not 100% sure that it’s saving that much on heating bills but not been using it that long. Easy to install.

Rated 4 out of 5 by from Excellent product Seems to be good, time will tell. Could really do with more double sided sticky tabs. It’s tough and durable also easy to cut and fit into position.

Rated 4 out of 5 by from Warmer! Easy enough to use, we used glue to stick it to the wall though, the pads are a bit hit and miss. Overall a good product though.
