The Air Vent in my lounge lets in loads of cold air, British Gas are doing my cavity wall insulation and have said that they will fit one that will prevent the air from coming in however this will cost £52, where can i buy one of these and what am i looking for and do they just replace the existing one and screw to the wall.
