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 partitions, when natural lighting and ventilation are needed.

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

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

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 the use of Class A fire-resistant windows that can close automatically.

When the horizontal distance between doors and windows adjacent to the firewall 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.

When windows are installed in the partition walls of hallways in Class 1 and 2 fire-resistant buildings, they should be equipped with Class B fire-resistant windows.
