Code Compliance
Blocks flames and smoke
Fire-protective glass prevents the passage of flames and hot gases during a fire. It is tested to NFPA 252 or UL 10C standards for fire doors and NFPA 257 or UL 9 for fire windows. This glass is appropriate for openings with size limitations as specified by the building code.
Blocks flames, smoke, and radiant heat
Fire-resistive glass blocks flames, smoke, and radiant heat transfer. It meets the full ASTM E119 wall test standard, meaning the glass-side temperature rise stays below dangerous levels. This allows unlimited opening sizes in fire-rated walls and barriers.
Applications
Building codes require fire-rated glass in specific locations throughout commercial and multi-family residential buildings. We install code-compliant assemblies in every application.
Exit stairways require fire-rated enclosures with rated doors and windows. We install fire-rated glass doors and sidelites that maintain required ratings while allowing natural light into stairwells for safety and wayfinding.
Fire-rated corridors in commercial buildings, hospitals, schools, and hotels require rated glazing in all openings. We provide fire-rated glass for corridor windows, borrowed lites, and door assemblies that meet the corridor wall rating.
Fire barriers between different occupancy types -- such as retail and residential, or office and assembly -- require fire-rated separations. We install fire-resistive glass walls that maintain the required separation while preserving visual connection.
Many jurisdictions require fire-rated elevator lobby enclosures. Fire-rated glass walls and doors create compliant lobbies that maintain open, transparent aesthetics while meeting elevator lobby separation requirements.
Educational and healthcare facilities have stringent fire-rated glazing requirements. We work with architects and facility managers to specify and install fire-rated glass that meets the specialized code requirements for these high-occupancy buildings.
Fire-rated glass upgrades for historic buildings in the DMV require balancing code compliance with preservation requirements. We provide fire-rated solutions that satisfy both the fire marshal and historic preservation authorities.
