Glidevale Protect FV100 Over Fascia Ventilator


Must always be used with RV Rafter Ventilators, to provide a continuous ventilation path from the roof void to the outside without impairing the weatherproof function of the structure, as required by BS 5250. They can also be used in situations where detailing is difficult and tile or slate ventilators are inappropriate, e.g. parapet walls, secret gutters, corbelled eaves and mono pitch ridges.


Glidevale Protect FV Fascia Ventilators are an unobtrusive method of providing ventilation in a range of eaves details, including those without a projecting soffit. FV100 Over Fascia Ventilator installed continuously provides guaranteed actual ventilation opening of 10 000 mm²/m.

Features and benefits:

  • Internal design provides effective resistance to both driving rain and large insects.
  • Unobtrusive when fitted, hidden by gutter and roof covering.
  • Can be used to provide ventilation above or below the underlay patented gutter bracket spacers ensure correct airflow behind the gutter.
  • Lightweight and durable.
  • Quick and easy to install, with no special tools required.
  • Compatible with all roof tile clips and eaves comb fillers.
  • Modular lengths allow adjustment for fascia board inaccuracies. Position on the fascia minimises the risk of fire spread to the roof space.
  • Integral dovetail joints ensure positive and continuous interlock between units.
  • Do not affect the slating/tiling process.
