Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a specified period. They should be used on the exterior walls of two buildings where the fire separation distance is insufficient, or between spaces separated by fire partitions, when natural lighting and ventilation are needed.

Fire-resistant window categories:
Fixed Fire Window: A fire window without an opening sash.

Operable fire-resistant windows: Fire-resistant windows with operable sashes and equipped with a sash opening and closing control device.

Insulating Fireproof Windows (Type A): Fireproof windows that meet both the fire resistance integrity and insulation requirements within a specified time.

Non-insulating fire-resistant windows (Class C): Fire-resistant windows that can meet the integrity requirements of fire resistance within a specified time. Divided by the fire resistance limit and insulating performance:
Fire-resistant window selection:

Fire-resistant windows are made of steel, available in two grades: Class A (fire resistance of 1.20h) and Class B (fire resistance of 0.90h).

Fire-resistant windows are primarily used in the fire-resistant walls of high-rise buildings, and require the use of甲级 fire-resistant windows that can close automatically.

If the horizontal distance between windows and doors near both sides of the fire wall is less than 2 meters, Class B fire-resistant windows should be used.

In addition to residential buildings, kitchens in other structures should be equipped with Class B fire-resistant windows.

One and two-level fire-resistant building lobby partition walls with windows should use Class B fire-resistant windows.
