American Commercial Glass is an authorized installer of Technical Glass Products (TGP) fire-rated glazing systems. From FireLite integrity glass for corridor views to FireFrame rated door assemblies in stairwells, ACG delivers compliant fire-rated glazing with complete UL documentation, NFPA 80 compliance, and the submittal package your special inspector needs.
Technical Glass Products manufactures UL-listed fire-rated glazing for both fire-protective (integrity only) and fire-resistive (full hose-stream and radiation control) applications. ACG installs the full TGP commercial line.
Wire-free fire-protective glazing. Clear vision panel for corridor doors and sidelites, stairwell enclosures, and office partitions. Rated up to 90 minutes for fire-protective (integrity only) applications. Does not provide radiation control — appropriate where IBC allows fire-protective glazing. Sizes up to 49" x 96".
Low-iron variant of FireLite for applications requiring higher visual clarity. Reduced green tint versus standard FireLite. Used in hospitality, healthcare, and education projects where the fire-rated partition must match the aesthetic of adjacent non-rated glass.
Ceramic fire-protective glass. Withstands thermal shock — cold water during hose-stream test will not cause breakage. 20, 45, 60, and 90-minute ratings. Used where IBC requires hose-stream resistance in fire-protective glazing assemblies.
Fire-resistive glazing (radiation control, hose stream) for applications requiring full 60 or 90-minute ratings with heat transmission limits. Used in rated floor-to-ceiling applications, smoke barriers requiring fire-resistive glazing, and atrium separation walls.
TGP's proprietary rated framing designed specifically for TGP fire-rated glass products. Slimmer sight lines than standard rated steel frames. Used in storefront-style fire-rated partitions where architectural appearance matters alongside code compliance.
Complete UL-listed door assemblies — frame, glass, and hardware — for stairwell enclosures and rated corridor separations. ACG installs fire-rated door assemblies with compliant hardware (Allegion closers, latches, coordinators) to maintain the UL listing of the assembly.
Fire-rated glazing is governed by a layered set of standards — not a single code reference. ACG's project team understands this framework and manages the documentation chain from product selection through special inspector sign-off.
| Standard | Subject | ACG Application |
|---|---|---|
| IBC Section 716 | Opening Protectives — fire doors, fire windows, fire shutters. Governs where fire-rated glazing can be used, maximum glass area per assembly type, and rating required by occupancy separation. | ACG uses IBC 716 to confirm product selection is appropriate for the fire-resistance rating required by the building's occupancy separation table (IBC Table 716.5). |
| NFPA 80 | Standard for Fire Doors and Other Opening Protectives. Installation requirements, hardware requirements, clearances, and field testing procedures for fire-rated door assemblies. | ACG installs fire-rated door assemblies per NFPA 80 clearance requirements. Positively latching hardware, door closers, smoke gaskets per NFPA 80 Section 4.8. |
| NFPA 252 | Standard Methods of Fire Tests of Door Assemblies. The test method used to achieve a UL label on a fire-rated door assembly. | ACG installs only tested assemblies with valid UL labels. No field modifications to frame, glass size, or hardware that would invalidate the NFPA 252 tested assembly. |
| UL 9 | Fire Tests of Window Assemblies. Test method for fire windows, fire-rated glazing in frames other than door assemblies. | ACG installs fire-rated window assemblies (sidelites, corridor windows, partition glass) with UL 9 listed configurations. Glass size, frame anchorage, and glazing method per the UL listing. |
| IBC Chapter 7 | Fire-Resistance-Rated Construction. Occupancy separation requirements, fire-resistance ratings, and where fire-rated assemblies are required by occupancy type and building height. | ACG coordinates with the EOR and architect to confirm the required rating for each opening before product selection. A 20-minute door in a 2-hour separation wall is a code failure ACG prevents upstream. |

Stairwell enclosure walls in mid-rise and high-rise buildings require rated assemblies with rated openings. Vision panels at stairwell doors are a common TGP FireLite application — maintaining sightlines for occupant wayfinding while meeting the required opening protective rating. ACG installs TGP FireFrame framing with FireLite glass and UL-listed rated doors.
Healthcare occupancies (I-2 per IBC) require smoke barriers with rated openings throughout the building. Nurse stations, medication rooms, and cross-corridor doors in smoke compartments require fire-rated glazing at vision panels and sidelites. ACG coordinates TGP system selection with infection-control and finish requirements common in healthcare construction.
Educational occupancies (E per IBC) require corridor separations with rated openings. Classroom corridor windows, office suites adjacent to rated corridors, and assembly spaces with rated partitions all present TGP fire-rated glazing applications. ACG installs in K–12 and higher education facilities.
Multi-tenant office buildings require fire-rated assemblies at occupancy separations and at shaft enclosures. Lobby-to-office separations with transparent glass walls, rated elevator lobbies, and fire-rated corridor systems use TGP products where aesthetic appearance is as important as code compliance.
Hotel corridor separation requirements and glass stair towers in high-end hospitality use TGP fire-rated glazing where the fire-rating requirement cannot compromise the visual design intent. ACG has completed fire-rated glazing scope on hospitality projects alongside Euro-Wall and storefront systems.
Emergency Operations Centers, fire stations, and police facilities (Risk Category IV per IBC) require enhanced occupancy separation in some configurations. ACG's experience at the Haines City EOC demonstrates essential-facility glazing delivery and coordination with institutional owners.
A TGP FireFrame door assembly is only UL listed when installed with hardware specified in the UL listing. ACG partners with Allegion — an authorized manufacturer partner — to supply closers, latches, coordinators, smoke-activated hold-opens, and other hardware components that are part of the tested assembly. Substituting unlisted hardware voids the UL label and creates a code deficiency at inspection.
Allegion LCN and Sargent closers included in TGP UL listings. Closing force, backcheck, and delayed-action settings coordinated with accessibility (ADA) requirements for door assemblies in accessible routes.
Positive-latching hardware per NFPA 80 required at all fire-rated doors. Allegion Schlage and Von Duprin products listed for use in rated door assemblies. ACG coordinates latch selection with keying schedule and master-key systems specified by the GC or owner.
Pairs of fire-rated doors require coordinators to ensure the inactive leaf closes first. Allegion coordinators sized per door weight and width. ACG installs and adjusts coordinators as part of the fire-rated door assembly scope.
Fire-rated glazing submittals require more documentation than standard glazing submittals. The following items are required for every TGP fire-rated glazing assembly ACG installs.
ACG submits this package through Procore Submittals on Procore-managed projects or via the GC's preferred platform on others.
