  • Unroll the ventilator along the rafters along the full length of the eaves and along 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 the roof insulation is most likely to constrict the airflow.
  • Push the corrugations down over the top of the rafters and secure using clout nails or staples.
  • Measure the overall length of the eaves to be ventilated and divide by 6m to determine the number of rolls of ventilator required.
