Hi-we have an integral garage, the internal door to the house has a fire strip on it but otherwise is just a normal internal door. The garage can get very draughty and the internal door allows draughts into the house, I've tried draughtproofing but still not sucessful. I have seen thermally insulated fire doors but they seem to be alot (£700)- is that what I need to make the room next to internal garage door more comfortable in winter? thanks for your help
