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

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 sash opening and closing control devices.

Insulating Fire Windows (Type A): Fire-resistant windows that meet both fire integrity and insulating requirements within a specified time frame.

Non-insulating fire-resistant windows (Class C): Fire-resistant windows that can meet the requirements of 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 (with a fire resistance of 1.20 hours) and Grade B (with a fire resistance of 0.90 hours).

Fire-resistant windows are primarily used in fire walls of high-rise buildings, requiring the use of甲级 self-closing fire-resistant windows.

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

In addition to residential buildings, kitchens in all other structures should use Class B fire-resistant windows.

One and two-level fire-resistant building vestibule partitions should use Class B fire-resistant windows when openings are made for windows.
