Insulating Fire Resistant Glass

NZFD stock and process the Schott Pyranova glass that NZFD process as part of our range of Fire rated timber window and door products.  Fire resistant glass within a fire rated wall requires an integrity and insulation value, expressed in time whether 30 or 60 minutes.   

The glass is a multi-interlayered laminated composition, designed to maintain its integrity (stay in place) in the event of a fire. Of equal importance, is its ability to resist the transfer of intense heat through the glass. The integrity and insulation qualities of the glass allows occupants to use the designated escape routes out of a building safely.

NZFD manufacture a fully certified system for interior windows and interior/exterior doors where glazing is required. The glass type has to match the fire rating of the door or window system.

Key Features
  • The glass is optically clear and no discernible difference in look to standard architectural float glass
  • The laminated glass acts as a Grade A safety glass by default for doors, full height window and sidelight applications
  • The glass can be used for exterior door applications due to the addition of a UV filter interlayer

Fire rated interlayer:

  • Pyranova 15mm thick -/60/30 and -/30/30 Interior
  • Pyranova 18mm thick -/60/30 and -/30/30 Exterior
  • Pyranova 23mm thick -/60/60 Interior
  • Pyranova 27mm thick -/60/60 Exterior
