Sorry about the subject title but I hope it wont happen! I am interested in foil insulation. Does anyone reckon it is possible to line a very cold wall in my front room with foil (the same stuff they use for space blankets) before putting up wallpaper. a) Will we slowly bake like a microwave? b) Will I receive radio luxembourg through the fillings in my teeth? c) Could it actually work, to reflect radiant heat and will the wallpaper stay up???
