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 insufficient fire separation between the exterior walls of two buildings, or when there is a need for light and ventilation between spaces separated by fire partitions, fire-resistant windows should be used.

Fire Window Categories:
Fixed Fire Window: A fire window without operable sash.

Operable fire-resistant windows: Fire-resistant windows with operable sashes and equipped with sash opening and closing control devices.

Insulation and Fire-Resistant Windows (Type A): Fire-resistant windows that meet both fire resistance integrity and insulation 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 the fire resistance limit and insulating performance:
Fireproof window selection:

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

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

Kitchens in all buildings except residential ones should use Class B fire-resistant windows.

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