Louvred Smoke Vent

Louvred Automatic Opening Vent

Stardome AOV louvred smoke vents are lightweight, compact, maintenance free and suitable for installation on flat or pitched roofs. The multi-channel drainage system and overlapping louvres guarantee a rain-proof system. All components are corrosion resistant and the ventilator side panels are reinforced by inner and outer longitudinal profiles.

A choice of louvre blade materials is available, including those that allow daylight into the building:

  • Single skinned aluminium.
  • Double skinned aluminium.
  • Multi-wall polycarbonate.
  • Single skinned laminate saftey glass.

All Stardome AOV rooflights operate via a 24v DC power open/power close actuator, which must be operated by a CE certified battery backed control panel.

This AOV unit can not be thermally broken to meet Part L of the building regulations and will not comply to BSEN12101-2.
