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

Fire-resistant window classifications:
Fixed Fire Window: A fire-resistant window without an opening sash.

Operable fire window: A fire window with an opening sash and equipped with a sash opening/closing control device.

Insulating Fire Windows (Type A): Fire-resistant windows that meet both 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 a specified time. Divided by fire resistance rating and insulating properties:
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, and Class A fire-resistant windows that can close automatically are required.

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 all other structures should use Class B fire-resistant windows.

When windows are installed in the partition walls of corridors in buildings with first and second fire resistance ratings, grade B fire-resistant windows should be used.
