Installation
Unroll the ventilator along the rafters, and this should be along the entire length of the eaves on both sides of the building, creating a cross-flow ventilation action.
Position centrally above the wall plates because it's the narrowest part of the roof and is most likely to constrict the airflow of the roof insulation.
Push the corrugations down over the top of the rafters and secure them using clout nails or staples.
