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.

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

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

Insulating Fire Window (Type A): A fire-resistant window that meets both fire integrity and insulating requirements within a 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 insulating performance:
Window Selection for Fire Retardancy

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-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 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.

When opening windows in the partition walls of hallways in buildings with first or second fire resistance ratings, grade B fire-resistant windows should be used.
