What fire ratings are available for commercial glass doors?
Commercial fire-rated glass door assemblies are available with certified fire ratings ranging from 20 to 90 minutes. Modern architectural designs utilize these fully glazed and large-lite fire doors to maximize natural light and visibility without compromising building safety.
To meet strict NFPA 80 standards and local Savannah building codes, these specialized vision panel doors feature heavy-duty frames constructed from fire-resistant aluminum or hollow metal steel. Depending on your facility's specific safety requirements, we supply and install both fire-protective and fire-resistive glass door assemblies to stop the spread of smoke and radiant heat.
Why are hollow metal swinging doors used for commercial fire barriers?
Hollow metal swinging steel doors and frames are the commercial industry standard for maximum durability, structural security, and fire protection. These heavy-duty steel doors provide the highest level of fire resistance—frequently rated for up to 3 hours (180 minutes)—making them essential for exit stairwells, industrial corridors, and high-security zones.To support visibility and applicable fire-door requirements, hollow metal assemblies can be custom-retrofitted with listed fire-rated door lites, vision panels, and compatible hardware when appropriate for the opening. At 911 Glass & Doors, we install, repair, and replace hollow metal fire-rated door assemblies using listed fire-rated components designed to support applicable fire door requirements, including common NFPA 80-related repair needs throughout the Savannah area.
Can architectural wood doors meet strict commercial fire ratings?
Yes. Commercial solid core wood fire doors are available with fire-resistance ratings of 20, 45, 60, and up to 90 minutes while maintaining an upscale architectural aesthetic. Ideal for hotels, luxury corporate offices, and multi-family apartment complexes, these assemblies merge beautiful design with strict life-safety protection.To achieve these higher ratings, many wood fire doors use mineral core construction and listed components tested by recognized agencies such as Warnock Hersey/Intertek or UL. Whether your project requires a flush solid slab or a custom vision panel door with fire-rated door lites, 911 Glass & Doors can help repair, replace, or upgrade the door, frame, closer, hinges, and positive-latching hardware so the assembly operates as intended.
