Over Facia Ventilators
Over facia ventilation is an unobtrusive method of introducing air into the roof void. Rytons over facia ventilators (OFV1000/OFV300) are available in two sizes and are also suitable as abutment vents for low-pitch and mono-pitch roofs as well as facia vents. Ventilation for flat roofs can be achieved with Rytons FR250 which is designed for use as an over facia vent or abutment vent.
