Hi - I have a 1935 house with solid walls. The whole house needs decorating (evantually) I was wonderign if there is a type of expanded polystyrene covering that you can glue to the brickwork and than put wall paper onto that - maybe about 10 or 15mm thick - I'm sure that would increase the insulation a lot compared to just bricks and wallpaper.
Has anyone heard of anything like this and prices?
