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.

Movable barriers having transverse stiffeners and methods of making the same

A door ( ) made in accordance with the present invention includes a plurality of panels ( ) with opposed stiles ( ) being positioned at the longitudinal edges of a faceplate ( ) of each panel ( ) and with opposed rails ( ) being positioned at the lateral edges of the faceplate ( ) of each panel ( ). An insulation assembly ( ) includes a sheet of insulation material ( ) and a backing sheet ( ) which has edges ( ) which overhang the lateral edges of the sheet of insulation material ( ). The insulation assembly ( ) is installed in the door ( ) by engaging the stiles ( ) with the longitudinal edges of the sheet of insulation material ( ) to flex the same until the edges are received in notches ( ) formed in the stiles ( ). Then the overhanging edges ( ) of the backing sheet ( ) engage the rails ( ) and deform to press the sheet of insulation material ( ) against the faceplate ( ).
