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

Fire-resistant window selection:

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

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 windows and doors near both sides of the firewall is less than 2 meters, Class B fire-resistant windows should be used.

Kitchens in all buildings except residential ones should be equipped with Class B fire-resistant windows.

When windows are opened in the partition walls of hallways in Class 1 and 2 fire-resistant buildings, grade B fire-resistant windows should be used.
