70mm Circular Push In Soffit Roof Vents
Installation Advice
The push in soffit ventilators are fitted to 70mm diameter circular holes, cut into the soffit board
These holes should be drilled at 160mm centres in order to provide airflow equivalent to a continuous 10mm opening
The push in ventilators are not ideally suited in situations where an airflow equivalent to a continuous 25mm opening is required
It is very important that the holes are cut accurately and are not oversized; otherwise, the ventilators will not grip firmly in the fixing holes
It is strongly recommended that a good quality and accurate hole saw is used
