For interior walls rated at 60 minutes, a window that is fire-rated for 45 minutes can be installed provided it does not exceed 25% of the wall’s total area. For windows that exceed this size, their fire rating must be tested to ASTM E119 standards and be rated equal to the wall.

Fire-rated windows and storefronts provide critical fire safety while improving visibility and light transfer. While traditional hollow-metal steel products are a proven solution, their frame profile size and shape may not match neighboring assemblies.

2024年9月25日 · Fire-rated windows are specialized glazing systems designed to withstand the spread of fire and smoke for a specific duration. In buildings where fire safety is a priority, these windows play a crucial role in ensuring that fire does not easily penetrate through walls or openings, providing essential time for evacuation and reducing property ...

2014年11月26日 · This article provides answers to FAQs on the IBC and exterior fire rated openings as it relates to fire protective vs. fire resistive glazing requirements. The fire resistance rating for exterior walls is based on construction type, occupancy and fire separation distance as defined in Section 6 of the IBC.

Where the code permits a fire rated window opening in a 1‐hour exterior wall, the required fire rating for the window and glazing is 45‐minutes, with the caveat that there are 25% width and length limits.

Codes require doors and windows that protect openings in these walls, barriers and partitions to comply with specific UL Solutions standards for safety and performance, and for doors and windows to have certain ratings in order to limit the spread of fire and/or smoke.

The International Building Code (IBC) sets forth requirements for the use of fire-rated windows, specifying where they must be used (such as in fire barriers, fire walls, and exit enclosures) and their minimum fire rating based on the building’s design and use.

2019年2月3日 · Where windows are provided in fire-resistance rated components (a fire partition or barrier, as sprinklers are not permitted to be used for fire walls), the opening must be addressed in a manner that maintains the fire-resistance of the rated enclosure. The driver for these requirements is the building code.

Our fire rated windows or openings can be used in the following applications: 45 minute fire protective windows, openings or borrowed lites. Can be used in interior and exterior fire rated applications. Browse our collection of educational video resources to help you learn more about fire rated glass and framing.

2018年2月14日 · Three principal options are available to architects and engineers looking to address windows within rated applications; a rated window assembly, closely-spaced sprinklers for atrium enclosures, and use of special application window sprinklers.
