Installation advice
Roll form eaves ventilator
- Unroll the ventilator along the rafters along the full length of the eaves and both sides of the building to create a cross flow ventilation action
- Position centrally above the wall plate
- This is the narrowest part of the roof where insulation is most likely to constrict airflow
- Push the corrugations down over the top of the rafters and secure using clout nails or staples
Over fascia vents - (OF1 or OF2)
- Fix ventilators to the top of the fascia board using screws or nails through the fixing holes provided
- Ventilation must be provided for the full length of the eaves along both sides of the building to create a cross flow ventilation action
Felt support panels 1128
- Fit directly on top of the over fascia vent
- Secure with clout nails driven into the top of the fascia board through the slots in the over fascia vent
- Ensure each panel is allowed to overlap the next
- Allow the rear of the panel to lay back on the rafters
