Abstract
A method to insulate an existing door for an existing cargo container, such as a boxcar. In one implementation, the method includes attaching a liner to at least one surface of the door, incorporating an insulating layer, and attaching a gasket to the liner. A door retrofit by this method will have improved thermal efficiency.
