OFV Over Fascia Ventilation 10 & 25mm

To comply with building regulations (approved document F2) all newly built properties must have continuous ventilation at eaves level to avoid damp and condensation within the roof void. Inadequate ventilation to the loft will cause structural damage to the roof timbers. Good loft ventilation is essential to remove moist air from the loft space, and ensures continuous airflow throughout the roofing system, thereby allowing the roof to ‘breathe’. Fitted on the top edge of the fascia board, this gives a clean and unbroken 10mm continuous air gap along the eaves
