Tapco Rafter Roll Ventilator Fixing Guide

Attach one piece of the Roll Ventilator by placing the end square corrugation over the rafter and fixing with staples or nails. The ventilator should be placed to ensure the airflow from the soffit area is not restricted by the roof insulation. By lightly stretching the roll along its length, the square corrugations will fall into line automatically with rafters at 400mm and 600mm centres and can easily be extended to suit 450mm centres.
