Heat insulated entrance

A building wall construction including a fixed wall portion defining an opening and a movable closure member adapted to open and close with respect to said opening;

• said fixed wall portion including an elongated wall frame member along one edge of said opening including an inside metal element, an outside metal element and a heat insulating element interconnecting said metal elements;
• said movable closure member including an elongated frame member assembly comprising;
• an elongated outside frame member of metal having an inside wall face with a rib along one edge,
• a spacer of heat insulating material including hook means along one edge for interengaged, hooked relation with said rib and an opposite edge, and
• an elongated inside frame member of metal having hook means along one edge for interengaged, hooked relation with said opposite edge of said spacer and having a rib element with a deformable portion adapted for deformed holding engagement with said one edge of said spacer for securing said cladding element in the assembly,
• said rib element positioned between opposite outer edges of said cladding element and including a deflectable rib for providing said holding engagement with said spacer hook means on said rib of said frame member,
• said cladding element including an opposite edge portion projecting beyond said rib element away from said frame member,
• said opposite edge portion of said cladding element includes means for supporting one face of an edge portion of a panel supported by said frame member assembly,
• said opposite edge portion of said cladding element including a flange parallel and spaced apart from said rib, and filler means inserted between said flange and rib.

A door/window comprising:

• an elongated, tubular metal frame member including an inside wall and an integral wall transverse thereto with a rib formed adjacent a corner formed by said walls;
• an elongated cladding member of metal having a channel shaped transverse cross-section with a web forming an inside wall face of said door/window and a pair of edge flanges transverse thereto;
• and
• a spacer of heat insulating material between said inside wall face and said inside wall for maintaining said members in heat insulating spaced apart relation, said spacer including hook means along one edge in interengaged hooked relation with said rib, and having a channel shaped transverse cross-section comprising a web in spaced apart relation with said web of said cladding member and said inside wall of said tubular frame member, and a pair of edge flanges of said spacer formed along opposite edges of said web,
• one of said flanges of said cladding member in supported engagement with an edge of said spacer remote from said one edge and said one edge of said spacer in supported engagement with said rib of said tubular frame member, said cladding member including a rib element deformable into holding engagement with said one edge of said spacer for securing said cladding element in heat insulating relation on said frame member of said door.
