Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a certain period of time. When there is a lack of fire separation distance between the exterior walls of two buildings, or between spaces separated by fire walls, and there is a need for lighting and ventilation, fire-resistant windows should be used.

Fire-resistant Window Categories:
Fixed fire windows: Fire windows without operable sash.

Operable fire window: A fire-resistant window with an opening sash and equipped with a sash opening and closing control device.

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

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

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

Fire-resistant windows are primarily used in fire walls of high-rise buildings, requiring the use of Class A fire-resistant windows that can close automatically.

If the horizontal distance between doors and windows adjacent to the fire wall is less than 2 meters, Grade 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-grade fire-resistant building vestibule partitions should use Class B fire-resistant windows when openings are made for windows.
