Fire-resistant windows refer to windows, including their frames, that can meet the requirements for fire resistance stability and integrity within a specified period of time. When there is a lack of fire separation between the exterior walls of two buildings, or when there is a need for lighting and ventilation between spaces separated by fire walls, fire-resistant windows should be used.

Fireproof 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.

Insulating Fire Windows (Type A): Fire-resistant windows that meet both fire integrity and insulating requirements within a specified time.

Non-insulating fire-resistant windows (Class C): Fire-resistant windows that meet the requirements for fire resistance integrity within a specified time. Divided by fire resistance rating and insulating properties:
Fire-resistant window selection:

Fire-resistant windows are made of steel, available in two types: Class A (with a fire resistance of 1.20h) and Class B (with a 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, kitchens in other structures should use Class B fire-resistant windows.

When windows are installed in the partition walls of hallways in buildings with first or second fire resistance ratings, grade B fire-resistant windows should be used.
