Abstract
A method of insulating an existing cargo container, such as a boxcar. The method allows for the application of improved insulation materials to improve the R-Value of an existing boxcar without building a new boxcar. In one implementation, the method includes preparing multiple insulating panels comprising an insulating layer and an outer skin located on at least one face of the insulating layer and attaching the insulating panels on an exterior surface of the side walls, end walls, and roof of the boxcar. The method also includes installing closures on uncovered areas of the boxcar and applying foam insulation to the bottom surface of the boxcar.
