Can anyone please help me with some advice regarding whether I require fire rated windows onto an escape route corridor. I have 12 apartments on the first floor and 12 apartments on the second floor with each flat having an entrance door and a kitchen window on to the corridor. I am looking to install a fire alarm to cover the routes of escape which would be both floors and 2 staircase at opposite ends of the building. The corridors previously had window openings and I have now installed building reg complaints windows with fire escape openings.
I have been advised of changing the kitchen windows to fire rated windows but I don’t understand why as the corridors have always been the route of escape. Your advice would be appreciated.
