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 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-resistant window without operable sashes.

Operable fire-resistant windows: Fire-resistant windows with operable sashes and equipped with sash opening and closing control devices.

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

Non-insulating fire-resistant windows (Class C): Fire-resistant windows that meet the requirements for fire resistance integrity within the 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 (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 Class A fire-resistant windows that can close automatically.

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

Apart from residential buildings, kitchens in other structures should be equipped with Class B fire-resistant windows.

One and two-level fire-resistant building entrance walls should use B-grade fire-resistant windows when openings are required.
