Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a certain 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 walls, when natural light and ventilation are needed.

Window Selection for Fireproofing

Fire-resistant windows are made of steel, available in two grades: Class A (fire resistance of 1.20h) and Class B (fire resistance of 0.90h).

Fire-resistant windows are primarily used in fire walls of high-rise buildings, and甲级self-closing fire-resistant windows 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, kitchen areas in other structures should use Class B fire-resistant windows.

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