How much heat your doors can retain and how much cold they let in through gaps between the door and the frame or sill will determine how energy efficient they are. There are a number of accessories, like weather strips and seals which can plug up gaps that are apparent when the door is closed - all of which can significantly contribute to your home’s efficiency. The materials your doors are made out of will also make a big difference in heat transfer through the doors themselves.
