how much do you know about fire windows?

I believe that many of friends are already familiar with the words fire windows, so how much do you know about fire windows? Let’s learn together today. A fireproof window refers to a window composed of a steel window frame, steel window sash, and fireproof glass, which can isolate and prevent the spread of fire. It is generally set in the openings or skylights on the outer wall of the building where the fire separation distance is insufficient, on the firewall or the fire partition wall in the building that needs to be observed, and on the openings on the outer wall where the fire prevention fire needs to spread vertically.
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.
