Fire-Resistive Glass
About the Fire-Resistive Rating
Tested according to UL 9, 10B, 10C, 263; ASTM E-119; CAN/ULC S101; 104, 106 and NFPA 80, 252, 257 to maintain structural integrity in the event of a fire, fire-resistive glass maintains building compartmentalization and prevents the spread of flames and smoke. When fire-resistant glass is heated, a series of reactions occur. First, the exposed layer of glass cracks and the first layer of intumescent material is activated. The panel becomes opaque, reducing heat transmission. Vetrotech fire-Resistive glass solutions are listed with an impact safety rating according to ANSI Z97.1, CPSC 16CFR 1201-CAT II, CAN/CGSB - 12.1-M90. Available in ratings ranging from 60-180 minutes, fire-resistive glass can symmetrically withstand high thermal stress and provides very high light transmission values.
Fire-Rated Glass Code Requirements and Testing Standards
ASTM E119: Standard test methods for fire test of building construction and materials
NFPA 80: Standard for regulating the installation and maintenance of fire protective openings in walls, floors, and ceilings.
NFPS A252: The standard for fire door systems
NFPA 257: The standard for fire-rated window assemblies, glass block, and other light-transmitting assemblies.
In accordance with the IBC (International Building Code), both fire-protection-rated glazing and fire-resistance-rated glazing are required to be permanently labeled with a multitude of information. These labels specifically identify the product name, basic characteristics and compliance with impact safety requirements. The letters now replace the test standard numbers - The IBC made these revisions to help in better matching the product with the application. If a product has been tested to more than one standard, it will show multiple letter markings. Refer to the markings listed here to indicate the type of assembly the glazing has been tested for as well as the number of minutes of fire resistance or fire protection.
