Fire Protective Glass

Tested to NFPA 252/257, UL 9/10B/10C, CAN/ULC S104/S106.

What is Fire Protective Glass?

Fire protective glass is a type of fire rated glass capable of containing flames and smoke, preventing it from transferring to other areas.  It meets NFPA 257 / UL 9 / CAN/ULC S106 for use in fire rated windows or openings and NFPA 252 / UL 10B/10C / CAN/ULC S104 for use in fire rated door assemblies.  All of our fire protective glass options meet ANSI Z97.1 Class A and CPSC Cat. II impact safety requirements.  Listed and labeled by UL and/or Intertek and proudly USA-made.

Fire protective glass is typically fire rated from up to 45 minutes and limited to 25% of the wall area.  They can also be used in 60-180 minute temperature rise doors up to 100 square inches.  Depending on the fire separation distance, they can also be used in 45 and 90 minute exterior fire rated windows or openings.

The codes limit the use of fire protective glass because it cannot block radiant heat.  To exceed the size limitations or use glazing where fire protective glazing is not allowed, designers can specify fire resistive glass instead.

The Dangers of Wired Glass

CBS Evening News report on injuries caused by unsafe traditional wired glass.

Traditional Wired Glass is Not Safe

Traditional wired glass is made with steel wire mesh that acts as a reinforcement. During a fire test, the grid holds the glass in place. Although believed to make the glass stronger, the sharp wires actually pose more harm than good and can cause serious injuries to people who come in contact with the installation. Before the development of wire-free, safety rated fire-rated glass, schools used traditional wired glass because of its capacity to contain fires while still allowing people to look through doors and windows.
