Fire-rated glazing — two categories
Fire-Protective Glazing
Limits the passage of flames and smoke but transmits radiant heat. Rated up to 45 minutes for ≤ 100 SF and 20 minutes for unlimited size. Common applications: corridor windows, door vision panels, transoms.
Fire-Resistive Glazing
Limits flames, smoke, AND radiant heat. Rated 60, 90, or 120 minutes. Treated as a wall assembly under the building code. Common applications: stairwell separations, exit access corridors, area separations.
Which is required?
IBC Chapter 7 / FBC dictates rating by occupancy, building type, and location within the structure. Fire-resistive is required where the assembly substitutes for a fire-rated wall. Fire-protective covers most door and small-opening applications.

Where we install fire-rated
- Healthcare — hospital corridors, ED separations, OR area boundaries
- Education — school stairwells, corridor separations, gymnasium walls
- Multifamily — unit-to-corridor doors, stairwell vision panels
- Federal / military — specified rated separations
- Office & mixed-use — high-rise stair enclosures, area separations between tenancies
- Hospitality — back-of-house separations, kitchen exhausts
Example project: Martin County Fire Training Facility — fire-rated assemblies installed by ACG.
Frequently asked questions
What’s the difference between wired glass and modern fire-rated?
Wired glass is largely obsolete in new commercial construction — banned in many applications by IBC since 2003 due to safety glazing requirements (CPSC 16 CFR 1201). Modern fire-rated uses ceramic, intumescent, or filmed/laminated assemblies.
Can fire-rated glass be impact-rated for HVHZ?
Yes — TGP and Vetrotech both make combined fire-rated and impact-rated assemblies. Rare but possible. Send drawings for spec confirmation.
What standards govern fire-rated glazing?
UL 9 (positive-pressure testing), UL 10B (neutral-pressure), NFPA 252 (door assemblies), NFPA 257 (window assemblies), and IBC Chapter 7. Florida adopts these by reference.
