Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a specified 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 classifications:
Fixed fire window: A fire window without an operable sash.

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

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

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

Fire-resistant windows are made of steel, available 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 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 fire-resistant wall 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 hall partitions should use Class B fire-resistant windows when openings are made for windows.
