All Aluflam fire-rated aluminum systems are supplied with clear fire-rated glass manufactured in the United States.  No wire glass products.

Depending on the fire rating requirements, there are different glass technologies in play.

60 / 90 / 120 minute

The glazing in this range is for fire resistance rated (ASTM E 119) assemblies and are required to block flame as well as restrict heat transfer for the rated time period.  To achieve this, the glass units are constructed of multiple clear glass panes separated by clear, solid intumescent interlayers. In the case of fire, the interlayers will react to the heat exposure and protect the glass while also limiting the transfer of heat through the glass unit.

The outboard lites are tempered, greatly reducing the risk of breakage during transport and installation.

45 minute

The glazing is for fire protective rated window assemblies and temperature rise rated vision doors.  As such, the glass is required to block flame for the rated time period as well as restrict heat transfer for a portion of the time.  To achieve this, the glass units are constructed of clear laminated glass separated by a clear, solid intumescent interlayer. In the case of fire, the interlayer will react to the heat exposure and protect the glass while also limiting the transfer of heat through the glass unit.

20 minute

The glazing is for fire protective rated window assemblies as well as for non-temperature rise rated vision doors.  It consists of clear, specialty tempered safety glass and will block flame for the rated time period.  It will not offer any restriction to heat transfer.

 

All glass products supplied with Aluflam systems meet impact safety ratings per CPSC 16C Part 1201 (Categories I & II)
