Hi, what would be the best way to insulate an apartment in a high rise? Originally (built in the 1960s) external wall was brickwork but they put cladding on top of it in the 1980s. Internal walls are plasterboard. So I have 3 layers: cladding, brickwork then plaster. Brickwork is probably in a very sorry state, I saw a glimpse of it while renovating the kitchen, there may be holes all the way through. I think there is a cavity between bricks and plasterboard. Would filling the cavity between bricks and plaster work? Should I tear down plaster walls, fix insulation boards to the brick walk then rebuild plasterboard walls? Would covering plasterboard with graphene wallpaper on the inside work? Thank you, I guess one would need to see it to decide but any tips would be welcome!
