Fire-rated Aluminum Windows

Aluflam’s fixed storefront window frames are constructed from thermally broken narrow aluminum extrusions filled with a proprietary fire blocking material. Window products are available in 20, 45, and 60 minute ratings for interior and exterior installation, and are fully tested and listed by Underwriters Laboratories to ANSI/UL 9 and UBC 7-4 (1997) standards. All Aluflam fire-rated products are MEA approved for use in the City of New York.

Our clear fire-rated glazing is manufactured by Vetrotech Saint Gobain. Glazing conforms to CPSC 16CFR1201 (CAT I & II) standards for impact while providing excellent clarity and sound reduction. Features and benefits include:

  • Clean, sharp lines of narrow extruded aluminum framing 
  • Large, wire-free glass areas
  • Barrier to radiant heat (60 minute only)
  • Energy efficient
  • Multitude of finish options

Aluflam windows are factory finished and fabricated complete before delivery — reducing installation and glazing to a conventional task for the commercial glazing contractor.
