Abstract
A thermally improved expanded store front system is disclosed including vertical mullions and horizontal members. The vertical mullions comprise a structural mullion portion which is securely attached to the sill and head members and an exterior mullion half removably secured by anchor means to said structural mullion. The mullions when assembled are adapted to receive clip means which secure the horizontal members in place without the need for screws thereby allowing the members to expand and contract without undue stress. The vertical mullions and horizontal members, which are cut to predetermined lengths may be easily spliced for typical multi-story applications.
Claims6
An improved fastener for securing a first cold metal section to a second warm metal section so as to provide a thermal break therebetween comprising:
- a unitary non-metallic insulating portion;
- said insulating portion being provided in part with a threaded hole;
- a screw portion;
- said screw portion comprising a head portion and a threaded stem portion;
- said threaded stem portion being received within said threaded hole;
- one of said metal sections being provided with means for securing said head portion thereto;
- the other of said metal sections being provided with means for receiving said insulating portion such that said one metal section abuts one side of a first part of said insulating portion and said other metal section abuts a second side of said first part of said insulating portion so as to provide a thermal break therebetween when said one metal section is assembled to said other metal section wherein said first part and said second part are adapted to be moved relative to each other along the axis of said screw portion.
