1m Over Fascia Vent

Description

Efficient and durable primary roof ventilator supplied in convenient 1m lengths.

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.

OF1 provides ventilation equivalent to a continuous 10mm opening (10,000mm²) and is used to ventilate pitched roofs of >15° and the roof void is uninhabited loft or attic space.

OF2 provides ventilation equivalent to a continuous 25mm opening (25,000mm²) and is used to ventilate pitched roofs of <15°, flat roofs or any roof where living accommodation is contained within the roof space.

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
