Fire windows are usually divided into two categories, namely fixed fire windows and movable fire windows. Fixed fire windows are fire windows whose sashes cannot be opened. All around is sealed and fixed. The movable fire window means that the window sash can be opened. The fire window can be closed under the action of the fire window opening and the closing device can be opened and closed. When a fire occurs, it can be automatically closed to prevent the fire from spreading. After opening, smoke can be discharged. The fire-resistance rating of a class A fire window is not less than 1.5 hours, that is, it can prevent the fire from spreading for at least 1.5 hours, while class B is not less than 1 hour, and class C is not less than 0.5 hours.
Fire window function:
Fireproof windows, as the name suggests, are windows that play a role in fire prevention. Generally speaking, they are windows that can prevent the spread of fire and isolate the fire when a fire occurs. Fireproof windows have the same functions of lighting and ventilation as ordinary windows.
