Yes that's it. It says breathable on the website and felt as if it was when I was putting it up.This stuff?

Doubt it's breathable - it's a kind of rubber foam. Your walls may still be able to "breathe" towards the outside though.
Do you feel it's made a difference? I'm always a bit sceptical about these insulated wallpapers because (at least in theory) the amount of insulation they can provide is really quite tiny.
It's made a real difference - the room warms up a lot quicker. If you hold your hand against it, it gets warm quickly while the house walls are cold to the touch. I've just got it on the external walls, which are rab construction (stone/clay/stone) and so no chance of cavity wall insulation, and external wall insulation would cost £10,000 or so and would fuck up the look of the house.
It used to be bitter in winter but that and the secondary glazing has made a real difference - I've got just about the only wood sash windows where I live and I didn't want to lose them. The conservatory has also made a real difference, heats up the house too.
The fan heater now warms the room up quickly when it used to be on all the time in midwinter. The link David Clapson put up from Friends of the Earth said "internal thin wall insulation which can be as much as 70-80% as effective" as proper internal insulation which I presume means batons against the wall and insulation/plasterboard. My rooms are just too small for that.
I'm plugging up any holes I can find in the building fabric now so hopefully it'll keep the heat even better,
Eta I find the 70-80% difficult to believe though, would like to see test results
