My poor little DS has to sleep in a room in the extension which is exposed on all three sides and has a flat roof. Needless to say, it loses heat pretty quickly! SO I called an insulation company and they sent a surveyor who said the cavity walls will already be insulate because it was built after 1990, so we must be losing heat through the roof.
He said a quick fix is to buy interior insulation tiles and stick them to the ceiling. He made it sound so easy! But I can't find interior insulation tiles ANYWHERE. Was he spinning me a yarn or am I missing a trick?
We already have a reflector behind the radiator, have had the windows insulated and have really thick curtains. Is there anything else we can do?
TIA!
