Rafter Roll Ventilators are designed to ensure a clear air path between roof underlay and insulation at all types of eaves, in accordance with Building Regulations Approved Document C2. They should be installed continuously with fascia ventilators or soffit ventilators, to provide a continuous ventilation path from the roof void to the outside without impairing the weatherproof function of the structure, as required by BS 5250. Laid continuously over the rafters before the underlay is fixed, the ventilator provides a maximum of 25,000mm²/m air flow (dependent on the eaves ventilation inlet provision). Universal, adjusts for 400 – 600mm rafter centres. 450mm width. * Does not affect the slating/tiling process. * Unique cross strengthening ribs on rafter trays prevent the underlay from sagging and blocking the airflow. * Reduce the risk of cold bridging by enabling insulation to be laid right into the eaves. * Lightweight and durable. * Quick and easy to install, with no special tools required. * Suits standard rafter spacing. * Independent of soffit and fascia ventilators, enabling use with any depth of soffit. Dimensions: 2 x 6 metre roll lengths (12 metres of coverage per box) by 450mm width.
