AOV’s are a proven means of ventilating smoke from protected corridors and lobbies in a fire situation. These AOV’s can range from automated roof hatches and louvres, to end of corridor wall mounted vents and internal smoke shaft doors.
Historically it was accepted that a suitable actuator may be fitted to a conventional window to convert it to an AOV. Since 2013 however, the Construction Products Directive (CPR) has stipulated that it is mandatory for construction products covered by a harmonised European standard (hEN) to be CE marked and tested by a recognised third party.
This essentially means that all AOV’s must be tested and CE marked as a complete unit to satisfy these mandatory requirements.
All of our AOV products therefore comply with the EN12101harmonised standard and are CE marked in compliance with CPR:2013.
