Fire-resistant windows refer to windows that, along with their frames, can meet the requirements for fire resistance stability and integrity within a certain period. When there is insufficient 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 selection:

Fire-resistant windows are made of steel and are available in two grades: Class A (with a fire resistance of 1.20h) and Class B (with a 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-level fire-resistant building lobby partition walls should have windows with Class B fire-resistant windows when openings are made.
