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

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

Operable fire-resistant windows: Fire-resistant windows with operable sashes and equipped with a control mechanism for opening and closing the sashes.

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

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

Fire-resistant windows are made of steel and are 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, and it is required to use 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.

In addition to residential buildings, kitchen windows in all other structures should be of Class B fire-resistant.

In the partition walls of hallways in buildings with Class 1 or Class 2 fire resistance ratings, windows should be fitted with Grade B fire-resistant windows.
