Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a certain period of time. When there is a lack of fire separation distance between the exterior walls of two buildings, or between spaces separated by fire partitions, 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: Grade A (fire resistance of 1.20h) and Grade B (fire resistance of 0.90h).

Fire-resistant windows are primarily used in fire-resistant walls of high-rise buildings, requiring 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, kitchen windows in other structures should be of Class B fire-resistant.

When opening windows on the partition walls of doors of Class 1 and 2 fire-resistant buildings, grade B fire-resistant windows should be used.
