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

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

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

Insulation and Fire Retardant Windows (Type A): Fire-resistant windows that meet both fire integrity and insulation requirements within the specified time.

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

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

When the horizontal distance between doors and windows near either side of the firewall is less than 2 meters, Class B fire-resistant windows should be used.

In addition to residential buildings, kitchen windows in other structures should be of grade B fire-resistant windows.

One and two-grade fire-resistant building vestibule partition walls should use Class B fire-resistant windows when opening windows.
