Glidevale Eaves and Low Level Vent

1 Eaves AND LOW Level VENTILATION SYSTEMSCI/SfB (47) Uniclass Pr_30_59_29 December 2016 Glidevale Eaves ventilationsystems have been designed to provide a rangeof solutions to introduce low levelventilation into roofspaces in an unobtrusive are two primary methods of introducing the ventilation at low Level either via the soffit in discrete units or continuous systems using the SV soffitrange or over the fascia in continuous systems using the FV fascia range. All provide full compliance with BS 5250 Control of Condensation in Buildings, theprimary means to comply with BuildingRegulations in the UK as well as providingdriving rain and large insect resistance. Once inside, it is important that the ventilation air actually reaches all parts ofthe roofspace to be able to remove high humidity air and reduce the risk of harmfulcondensation from forming. To ensure thisoccurs, the RV rafter trays are available in arange of styles to suit numerous applicatons and are designed to ensure aclear, unobstructed path from SV or FV ventilators to the , ApplicationsFV Fascia Ventilators are an unobtrusivemethod of providing ventilation in a range of Eaves details, including those without aprojecting soffit.

2 They must always be usedwith RV Rafter Ventilators, to provide a continuous ventilation path from the roofvoid to the outside without impairing theweatherproof function of the structure, asrequired by BS 5250. They can also be used in situations wheredetailing is difficult and tile or slate ventilators are inappropriate, parapetwalls, secret gutters, corbelled Eaves andmonopitch ridges. FV250 Ventilator canalso be used for flat roofs. FV100 Over Fascia VentilatorInstalled continuously, providesguaranteed actual ventilation opening of 10 000mm2/m.
