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 walls of high-rise buildings, requiring the use of甲级 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 Grade B fire-resistant type.

One and two-grade fire-resistant building vestibule partition walls should use Class B fire-resistant windows when openings are made for windows.
