Fire-resistant windows refer to windows, including their frames, that meet the requirements for fire resistance stability and integrity within a specified time period. When there is insufficient 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 window: A fire-resistant window with an opening sash and equipped with a sash opening/closing control device.

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

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

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

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 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 other structures should be equipped with Class B fire-resistant windows.

One and two-grade fire-resistant building vestibule partition walls should use Class B fire-resistant windows when openings are made for windows.
