An improved method of manufacturing an insulated metallic edge guard, such as a door edge guard, comprises applying an insulating layer to one side of the metal strip which remains on the strip for protecting and insulating the edge guard from the object on which it is installed when in use, applying a protective layer to the opposite surface of the metal strip for the purpose of protecting the appearance of the strip during manufacturing, forming the laminated metal strip into a U-shaped cross section of desired configuration and then stripping the protective layer which is on the exterior of the U-shaped cross section from the door edge guard to expose the exterior of the metal to view.
