Fire-resistant windows refer to those 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, available in two grades: Class A (with a fire resistance of 1.20 hours) and Class B (with a fire resistance of 0.90 hours).

Fire-resistant windows are primarily used in the fire-resistant walls of high-rise buildings, requiring the use of甲级 self-closing fire-resistant windows.

When the horizontal distance between windows and doors near both sides of 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 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, Class B fire-resistant windows should be used.
