Automatic opening vents (AOV) protect building occupants in the event of a fire
An automatic opening vent (AOV) is a critical part of commercial building design. AOV rooflights can be specified to offer additional safety in the event of a fire. If a fire breaks out in a building, AOV rooflights work to remove smoke quickly from a commercial building. This helps to preserve oxygen and maintain visibility for occupants to exit more safely. AOV rooflights also lower the temperature of a building with the introduction of cool air.
