Abstract

Abstract This insulated door construction includes extruded plastic framing members and sheet plastic side panels, which are connected without the use of fasteners. The framing members are U-shaped and include spaced inner and outer legs which are sprung apart to clamp the side panels in place. The door includes an expanded foam plastic core which cooperates with the framing members to resist separation of the framing members and the side panels. In one species the inner legs of the framing members are held apart by foam-embedded transverse spacer members. In another species, particularly adapted to suit hingedly mounted doors, a continuous interior member cooperates to hold the framing members in place and provide reinforcing for the hinge mounting.
