ABSTRACT:
A movable door panel having a front facer with opposed longitudinal edge profiles, rails secured to the longitudinal edge profiles, a rear facer secured to the rails, and foam disposed within an inner volume defined by the front facer, the rails and the rear facer is disclosed. Transverse stiffeners are disposed within the inner volume and the foam, and extend between the opposed rails. The door panel may be made by continuously providing the front facer with a rail secured thereto, continuously positioning transverse stiffeners on the front facer and extending between the metal rails, and continuously applying a foaming material on the front facer and the transverse stiffeners. The method concludes by bringing a rear facer into contact with the metal rails, and drawing the panel through a laminator. Hardware may then be attached to one or both of the facers and the stiffener.
