This is a small single zone smoke vent system supplied for a stairwell in a multi occupancy building in London.
For this high-end flat conversion project in London we specified one of our EN12101-2 tested flat glass roof vents to provide a better-quality finish to the project.
This AOV roof hatch was required for the top of the stairwell, where you commonly need to achieve a 1mtr square free vent area to clear the smoke from the escape route.
The roof vent installed is 1.4mtr x 1mtr vent with a toughened flat glass lid that will open to 140 degrees in the event of a fire. Finished in white
This roof vent includes 6mm toughened low ‘E’ Glass which improves the heat loss during the winter and helps to reduce the heat build-up in the summer.
This system is connected to the communal fire alarm panel, which will activate in the event of a fire. The fireman’s override switch provides full manual control of the vent at the ground floor entrance as required by the fire brigade on entry.
