Abstract: A garage door panel apparatus is formed with a metal sheet and having an insulating barrier strip connecting the inner and outer metal sheets of each panel to block conduction of heat between the front and back metal sides. The barrier strip holds front and back sheets together and provides a support for the weatherstrip. The metal sheet is filled with a rigid polymer foam which acts as insulation and support for the metal sheet. The method provides for making of a garage door panel in which the metal sheet of the front and back panels are joined by a barrier strip which holds the sheets together in a spaced relationship to each other. The expansion of the polymer foam within the door panel metal sheet increases the pressure to lock the barrier strips onto the edges of the panel's metal sheet. Thus, the barrier strip locks the front and back metal sheets together while forming an insulator against the conduction of heat through the metal and simultaneously providing a support for weatherstripping.
