What Are AOV's?AOV's, or Automatic Opening Vents, are rooflights which have been designed to reduce smoke buildup and therefore provide a safer escape route for the buildings occupants. In the absence of a method of smoke ventilation, smoke fills the room being drawn back down from the ceiling by convection as temperatures rise, leading to potential - and particularly dangerous - 'flashover'. This is the stage of a fire whereby a room or other confined area becomes so heated that the flames flash over and through the vapours being produced by heated combustible contents in the space. The specific design of an effective and safe AOV smoke ventilation system requires specialist involvement, perhaps by the mechanical and electrical consultant, and may well form part of a fire engineering solution. |
