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 when there is a lack of fire-resistant spacing between the exterior walls of two buildings, or between spaces separated by fire partitions, where natural lighting and ventilation are needed.

Fire-resistant Window Categories:
Fixed Fire Window: A fire window without operable sashes.

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

Fire-resistant window selection:

Fire-resistant windows are made of steel, available in two grades: Grade A (resistance to fire for 1.20 hours) and Grade B (resistance to fire for 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 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 all 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.
