I'm looking for some rock-wool or similar insulation that has a 'skin' on one side. I want to use it to cover a very rough bit of wall behind a cupboard so that the back of the cupboard looks reasonably civilized.
The insulation characteristics don't have to be wonderful but would be handy, it probably wants to be 2" thick or so (1" might be enough).
I've looked in a few places but cant see anything much like this but I'm sure I've come across it in the past.
Does anyone have any ideas/pointers please.
(... and yes, I *could* put a back on the cupboard but it's very inaccessible and the above approach of sticking something to the wall will be easier).
