this is more of a case of more info needed then something cut and dry.. the facts are, the best way to keep a room over a garage warmer is to add heat to the garage, which in alot of places , can only be done with electric heat, which is very costly, or by spray foaming or having blown in insulation installed in teh garage ceiling, The reason rooms over garages are cold is because the heat move downwards. So limiting the heat transfer that way, is FAR more cost effective then trying to keep the garage a few degrees warmer., which is all treating the door will do.
