Self-Closing Fire Doors with Glass

Critical Considerations Across All Scenarios:

Fire Rating:Matched to the compartmentation strategy and hazard (20 min, 45 min, 1 hr, 1.5 hr, 3 hr).

Smoke Control:Intumescent strips and smoke seals are mandatory for effective compartmentation.

Hardware:Certified hinges, latches, closers (often self-closing or automatic-closing on alarm), and potentially electromagnetic 

holders connected to the fire alarm system. "Delayed Egress" hardware is common in secure areas but has strict limitations.

Clearance & Installation:Must be installed per manufacturer and code (NFPA 80, IBC) with minimal gaps around the perimeter and under the door.

Signage:Clearly marked as "Fire Door", "Keep Closed", or "Automatic Closing".

Inspection & Maintenance:Regular, documented inspections are crucial to ensure functionality (closing fully, latching, no damage).

Certification Standard

Intertek has conducted an evaluation for Shenzhen Longhui Sanhe Security Technology Co., Ltd. to determine the fire resistance performance on one fully glazed insulated single leaf double action steel composite fireproof door, model of BXGBLFHM 1024. The doorset is required to provide a fire separating function and was therefore tested in accordance with EN 1634-1:2014+A1:2018 'Fire resistance and smoke control tests for door, shutter and openable window assemblies and elements of building hardware.
