Fireswiss is a fire-resistive glass used in Temperature Rise Rated doors.
It is a thick multi-laminate glass that absorbs the heat of a fire for its designated fire-rating in minutes. This keeps the non-fire side cold permitting its use in large sizes in TRR doors. Care must be taken by door manufacturers to mount the glass in a way that insulates the glass frame as well. We welcome door OEM enquiries about using Fireswiss in your TRR doors.
Fireswiss passes ASTM E-119 when mounted in an appropriate insulated frame. It is fully UL tested and certified.
It passes impact-safety standard ANSI Z97.1 UA in large sizes.
