Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

B32B 3/06

US Classification:

428 99, 5220467, 5220468, 5220462, 52208, 5278611

Abstract:

This invention is an architectural glazing structure for exterior mounting that is a glass laminate having enhanced resistance to being pulled from a frame upon being subjected to severe positive and/or negative pressure loads. This invention is particularly suitable for architectural structures having windows that can be subjected to the extreme conditions prevalent in a hurricane, or window that can be placed under severe stress from repeated forceful blows to the laminate.

US Classification:

052/204620, 156/099000, 052/786110

Abstract:

This invention is a process of preparing a glazing structure that is a glass laminate having enhanced resistance to being pulled from a frame upon being subjected to high positive and/or negative pressure loads. This invention is particularly suitable for architectural structures having windows using a silicone structural glazing design that can be subjected to the extreme conditions prevalent in a hurricane, explosion, or placed under stress from repeated forceful blows to the laminate.

US Classification:

Abstract:

A drainage system is disclosed for building framing systems comprising weep holes for draining water from an interior cavity to the exterior of the buildilng. The drainage system comprises a weep valve overlying a weep hole in a frame member which provides a passage for infiltrated water from a glass pocket to the exterior of the building while at the same time preventing air infiltration. The weep valve includes a membrane of an elastomeric or other suitable material having a slit formed therein which permits water to seep out. The slit seals sufficiently tightly that, when the framing system is under windload, airflow back through the weep hole is substantially eliminated. Since water infiltration is a result of air infiltration, water infiltration is thus also substantially eliminated.
