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 insufficient fire separation between the exterior walls of two buildings, or when there is a need for lighting and ventilation between spaces separated by fire walls, fire-resistant windows should be used.

Fireproof Window Categories:
Fixed Fire Window: A fire window without operable sashes.

Operable fire windows: Fire windows with operable sashes and equipped with controls for opening and closing the sashes.

Insulating Fire Window (Type A): A fire-resistant window that meets both fire integrity and insulating requirements within a specified time.

Non-insulating fire-resistant windows (Class C): Fire-resistant windows that meet the fire integrity requirements within specified time. Divided by fire resistance ratings 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 the fire-resistant 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 fire-resistant wall is less than 2 meters, Class B fire-resistant windows should be used.

In addition to residential buildings, kitchens in all 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.
