Fire Rated Glass Doors

Description
Fire-rated glass doors are engineered to act as a transparent barrier against the spread of flames and smoke. Unlike standard glass, which shatters under the thermal shock of a fire, the glass in these doors?typically ceramic, wired, or multi-layer intumescent glass?is specifically treated to remain intact in extreme temperatures.
These doors are categorized into two main types: Fire-Protective (which blocks flames and smoke) and Fire-Resistive (which also blocks radiant heat to keep the non-fire side cool). This dual capability makes them essential for protected escape routes in schools, hospitals, and high-end commercial offices. Encased in reinforced steel or timber frames, these assemblies ensure that aesthetics never come at the expense of life safety.

Key Features
Maximum Transparency: Provides clear lines of sight, which is crucial for security and safe evacuation during emergencies.
Radiant Heat Shielding: Available with “Fire-Resistive” glazing that prevents heat from transferring through the glass, protecting people in exit corridors.
Hose Stream Resistance: Most glass doors (45+ mins) are tested to withstand the high-pressure impact of a fire hose after being heated.
Acoustic Control: The multi-layered construction of fire glass naturally provides excellent sound dampening (STC ratings up to 45dB).
Positive Pressure Certified: Meets UL 10C standards to ensure the door remains secure against the pressure changes of a fire.
Impact Safety: Rated for CPSC Cat II impact resistance, making them safe for high-traffic public areas.
