ABSTRACT:
A plastic storm door comprising a unitary molded plastic panel having an integral solid skin. The panel has a channel along its peripheral edge having integrally molded load-transferring ribs diagonally traversing the width thereof. Hinges are secured along a vertical edge of the panel by attachment to tapping plates mounted within the channel between and bridging two of the load-transferring ribs. The ribs act to uniformly distribute the loading forces on the hinges throughout the panel. Elongated plastic strips enclose the channel to form an insulating airspace therein.
