The Manthorpe Continuous Soffit Ventilator is designed for use with a traditional fascia board to provide roof ventilation.
The UPVC strip is screwed on to the fascia and securely supports the soffit board which slots into the self-retaining mouth. Airflow is guaranteed through a series of evenly spaced slots, narrow enough to keep out large insects but large enough to prevent the vent from becoming blocked. A sloping version of the product is also available.
