Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a specified period. They should be used on the exterior walls of two buildings where the fire separation distance is insufficient, or between spaces separated by fire walls, when natural lighting and ventilation are needed.

Fireproof Window Categories:
Fixed fire window: A fire window without operable sash.

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

Insulation Fireproof Windows (Type A): Fireproof windows that meet both the requirements of fire resistance integrity and insulation within the specified time.

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

Fire-resistant windows are made of steel and come in two types: Class A (fire resistance of 1.20h) and Class B (fire resistance of 0.90h).

Fire-resistant windows are primarily used in fire-resistant 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 both sides of the fireproof wall is less than 2 meters, Class B fireproof windows should be used.

In addition to residential buildings, kitchen areas in other structures should be equipped with Class B fire-resistant windows.

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