Hi everyone,
I`m redocorating the house, and have damaged some reflective material
while removing it from behind a radiator. It`s a foam type material
with a foil covering on one side, to reflect heat from the wall. IIRC
when
it was first put there it did make a difference to the
temperature in the room, so i`d like to replace it. Any ideas for a
cheap source of this stuff?
Thanks in advance for your help!

You need to buy a roll of this.

It's foam-backed foil, which you stick on the wall with heavy-duty
wallpaper
paste. You may also be able to get it from some of the sheds and/or
plumbers
merchants.

Course your only doing this on external walls with rads on aren't
you;?...

Yes, but what is the damage doing it on an internal wall with a radiator
on?
While I accept that any heat going into the wall is going towards heating
the room, why not try and heat the air as quickly as possible before
warming
up large chunks of plasterboard, so the room feels warmer? :-)

Well suppose thats one way of looking at it;!...

No i`m genuinely curious as to which would be more efficient, both in the
end result and for a quick heating of the room. Realistically any heating
of the wall past the surface is heating something that won`t directly warm
the room the wall is attached to, but would it then release this heat over a
period of time, keeping the room warmer than if the wall hadn`t been warmed.
And I mean by a meaningful amount, not by fractions of a degree :-)
