Fire-resistant windows refer to windows that, along with their frames, can meet the requirements for fire resistance stability and integrity within a specified period.

Fire-resistant window selection:

Fire-resistant windows are made of steel, available in two grades: Grade A (fire resistance of 1.20 hours) and Grade B (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 Class A fire-resistant windows that can close automatically.

If the horizontal distance between windows and doors near either side 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.

In the case of windows being opened in the partition walls of corridors in Class 1 and 2 fire-resistant buildings, grade B fire-resistant windows should be used.
