| Glass Area Limits | Exposed glass area and dimensions follow tested and approved configurations |
| Frame Material | Steel or stainless steel profiles designed for fire testing and sealing |
| Sealing System | Fire-rated glazing seals, beads and perimeter gaskets as part of the tested assembly |
| Hardware | Fire-rated hinges, closers, locks and optional panic or access-control devices |

| Typical Application | Corridors, lobbies, cleanroom entries, hospital areas and industrial fire compartments |
The glass fire door leaf is built with steel or stainless steel profiles sized to carry the glazing weight and maintain structural integrity under fire exposure. Internal reinforcements and connection details are chosen to keep the leaf stable during thermal loading and mechanical use.
Fire-rated glass is installed in frames and beads that have been tested together with the door leaf. Seals and interfaces are part of the certified assembly, controlling heat transfer, flame spread and integrity. Exposed glass area and dimensions follow the approved configuration for the door system.
Fire compartments in hospital or cleanroom corridors where visibility and light are needed alongside certified fire resistance.
Lobby and entrance doors that form part of fire partitions, combining transparent design with tested door assemblies.
Doors in stair and exit enclosures where fire-resistance and observation of traffic are required by design and code.
It is a fire-rated door with integrated fire-rated glazing, used where visibility and light are needed along with fire resistance.
The door and glazing are tested together for a specific period under standards such as EN 1634-1 or equivalent national tests.
Only glazing tested and certified for the required fire class can be used, either fire-protective or fire-resistive depending on code.
Yes. Codes and test data limit exposed glass area and dimensions; vision panel sizes must follow the approved assembly.
It is held by tested frames and beads with approved seals, all part of the certified fire door system.
They can, provided surface finishes and glazing choices meet both fire and hygiene requirements.
Fire-rated hinges, closers, locks and access-control devices tested with the assembly are compatible.
Installation must follow tested details, with controlled clearances and proper anchors and sealants.
Regular inspection and certified replacement of any damaged seals, glazing frames or hardware are required.
Fire test reports, classification data, installation instructions and maintenance guidance are provided for compliance checks.
