Fire-rated glazing assemblies for interior and exterior applications requiring code-mandated fire resistance. Tested, labeled assemblies rated 20 minutes to 2 hours.
Fire-rated glazing allows architects to maintain visual openness in areas where fire codes require rated separations — corridors, stairwells, atriums, exterior wall openings, and occupancy separations. ACG installs assemblies from Technical Glass Products that are UL-tested and labeled.
Fire-rated glazing is detail-sensitive work. Product selection must match the rating requirement. Framing must be a listed assembly. Labels must be visible for inspection. ACG partners with architects and code reviewers to ensure every assembly meets specifications without compromise.
There is a critical distinction between fire-protective and fire-resistive glass, and specifying the wrong product can result in failed inspections, redesign, and project delays. ACG's team understands the difference and advises architects and GCs on the appropriate system for each application.
Fire-protective glass (such as ceramics) blocks flames and smoke but allows radiant heat transfer. Fire-resistive glass (such as intumescent interlayers) blocks flames, smoke, and radiant heat. ACG installs both types in properly listed framing assemblies.
ACG installs fire-rated glass assemblies rated from 20 minutes to 2 hours, depending on the application and code requirement. Ratings are determined by the glass type and framing assembly, both of which must be UL-listed as a complete system.
Fire-protective glass blocks flames and smoke but allows radiant heat transfer. It is typically used in 20-minute to 90-minute applications. Fire-resistive glass blocks flames, smoke, and radiant heat, making it suitable for 60-minute to 2-hour applications where occupants may be in close proximity.
Modern fire-rated glass products are available in clear, transparent options that closely match the appearance of standard glass. The difference is virtually invisible to building occupants while providing life-safety protection.
