Double Pitch Smoke Vent

Double Pitch Automatic Opening Vent

Stardome AOV rooflights can be supplied with thier own kerb for fixing directly to the roof deck and then weathered to the roof in the traditional manner.

Alternatively if a kerb is being constructed as part of the roofing sustem (i.e. metal roofing or a builders timber kerb) we are able to supply a kerb adaptor. Both kerb and kerb adaptor units are manufactured from folded galvanised steel or aluminium, both materials being polyester powder coated white however can not be thermally broken to suit the requirements of Part L of the building regulation.

The lid or top of the AOV unit can be supplied in three forms:

  • Solid metal panel, insulated and polyester powder coated - Generally at the head of a smoke shaft when only ventilation is required instead of natural light.
  • Glazed top in single, double or triple skin polycarbonate.
  • Glazed top with a double glazed glass unit with a toughened outer pane and laminated inner pane.

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

This double pitch smoke vent rooflight can not be thermally broken to meet Part L of the building regulations, but it will comply to BSEN12101-2.
