Do these products actually work

[Slider]

Do these following products actually give a noticably difference in heat from radiators?

Anyone on here used these who can comment?

No, basically.

the radiant losses to the walls are very very low. If you have solid brick, and the B&Q tiles have a couple of mm of styrene foam,that will make a bit of difference tho.

My mother had some people round to improve her insulation. (One of those free for oldies programmes.) They puty these reflective things behind all her radiators. All of which are on internal walls. Definitely not worth doing that!
