In the field of building safety, fireproof glass fixed windows have become an indispensable fire separation facility in modern buildings due to their unique fire resistance and functional design. They can not only block the spread of high temperature and smoke in a fire, but also provide natural lighting and spatial transparency for the building. The following analyzes its core functions and wide application scenarios from multiple dimensions.

Definition and core functions of fireproof glass fixed windows

• Fireproof glass fixed windows are a fixed window structure composed of fireproof glass and fire-resistant frames. In the standard fire resistance test, they must meet the fire resistance integrity of at least 60 minutes (some products can reach more than 2 hours), and some advanced products have both thermal insulation (Class A). Its main functions include:

• Blocking the spread of fire: Through the combination of high-strength glass and frames, a physical barrier is formed to delay the spread of flames and high-temperature smoke.

• Smoke exhaust and heat dissipation: In case of fire, smoke heat can be discharged through manual demolition to reduce the internal temperature of the building and prevent structural collapse.

• Assisted evacuation and rescue: Buy time for people to escape and provide a safe passage for firefighters to attack and extinguish the fire.

Six application scenarios of fireproof glass fixed windows

1. High-rise buildings and smoke-proof stairwells

• Specification requirements: According to the design specifications of smoke-proof stairwells, fixed windows of no less than 1 must be set at the top, and fixed windows with a total area of ≥2 should be set every 5 floors of the stairwells near the outer wall to ensure the effectiveness of the mechanical smoke exhaust system in case of fire.

• Case application: For example, the stairwells of shopping malls and office buildings often use steel frames with Class C fireproof glass (such as single-layer cesium potassium glass), which not only meets the fire resistance requirements but also maintains transparency.

2. Industrial plants and storage spaces

• Places with dense combustibles: Class C plants such as wood processing plants and plastic warehouses. Fixed windows can replace traditional walls to provide natural lighting. Fusible light strips (5%-10% of the area) are also allowed to be used to meet smoke exhaust needs.

• Special design: Non-insulated glass (Class C) is often used in industrial environments, combined with wind pressure-resistant structures (such as curtain windows with wind pressure resistance of 6000Pa) to meet the needs of large-span spaces.

3. Commercial complexes and public areas

• Fire partitions: In shopping mall atriums, food courts and other areas, fixed windows are used as fire partitions to divide the space while maintaining visual continuity. For example, a department store in Taipei has fireproof glass fixed windows combined with sliding door design, which is both smoke-proof and aesthetically pleasing.

• Curtain wall integration: Fireproof fixed windows are embedded in the glass curtain walls of high-rise buildings, such as outdoor products with a wind pressure resistance of 2800Pa, which can withstand strong winds and meet fire protection regulations.

4. Medical and educational facilities

• Refuge floors and safe passages: The external windows of the refuge rooms in hospitals and schools must use Class B or above fireproof windows. Fixed windows in such places can ensure safe evacuation in emergency situations.

• Laboratories and clean spaces: Use frameless or narrow-edge fireproof glass to avoid dust accumulation and meet cleanliness requirements, such as the restaurant partitions at the Linkou Chang Gung Memorial Hospital Transfer Station.

5. Residential and community buildings

• Inter-household fire prevention: For residential exterior windows adjacent to fire walls, fixed windows are set to prevent horizontal fire spread and reduce the distance between windows of two households (if the original requirement is 2 meters, the distance requirement can be cancelled after setting).

• Light wells and skylights: For the top floor lighting area of villas or duplexes, the fixed window area must be ≥ 2% of the floor surface, and heat-insulating glass (Class A) must be used to prevent ignition by heat radiation.

6. Special structural buildings

• Breathing curtain wall and billboard: The facade uses Class C fireproof glass fixed windows, matched with flame-retardant curtains, to prevent external fire sources from spreading through the curtain wall cavity.

• Historical building renovation: While retaining the original architectural style, invisible frame fireproof glass replaces traditional windows to meet modern fire protection requirements.
