One way to save energy with doors

By: Rachel Skillicorn

Energy saving doors are a great way to start saving money. They have a double or triple-paned insulating the glass so that it will reduce the heat flow. Another thing they do to make them energy effiecent is that they now have a tighter frame with magnetic strips to create a tighter seal so that less air can get through. The last thing that they do to is they improved the core materials so you can have a stronger door.
