Over Fascia Vent

Durable and multi-purpose primary roof ventilator suitable for new build and refurbishment projects. An over fascia vent is used when the fascia board is fitted in the ends of the rafters, creating a situation where ventilation can only be positioned over the top of the board.

Uses:

  • For roof eaves ventilation
  • For flat roof abutment ventilation
  • On roofs where the eaves incorporate a fascia board
  • On roofs which do not incorporate a soffit board, or where an unbroken soffit board is required

Over fascia vent – Product 3011
Provides ventilation equivalent to a continuous 10mm opening (10,000mm2 per metre run)

Over fascia vent – Product 3011-25
Provides ventilation equivalent to a continuous 25mm opening (25,000mm2 per metre run).

Both products are supplied in 300mm lengths.

  • Use product 3011 to ventilate pitched roofs, where the pitch of the roof is 15 degrees or more, and the roof void is attic or loft space.
  • Use product 3011-25 to ventilate pitched roofs, where the pitch of the roof is less than 15 degrees, flat roofs, or any roof where living accommodation is contained within the roof space.
  • Make sure each ventilator is fixed securely into the top of the fascia board using at least three screws or nails per ventilator.
  • On pitched roofs it is advisable to provide a felt support above the fascia ventilator, projecting at least 10mm beyond the front of the ventilator. This will prevent the felt from sagging behind the fascia board and will maintain a clear air path at the front.
  • When ventilating flat roof abutments with product 3011-25 some extra joinery work is essential – please consult Timloc Technical Department.
  • Ventilation must be provided for the full length of the eaves and along both sides of the building to create a cross flow ventilation action.
  • Determine whether the roof design requires ventilation equivalent to a continuous 10mm opening (3011), or 25mm opening (3011-25).
  • Specify which colour is preferred.
  • Measure the overall length of the eaves to be ventilated and divide by 300mm to determine the number of lengths required.
