Manthorpe’s slim line over fascia ventilator ensures a flow of air into the roof space between the felt and the fascia board. 10,000mm² and 25,000mm² versions available.
The product is designed with clear fixing points and a smooth leading edge allowing it to sit discreetly on top of the fascia board beneath the felt, both versions come complete with an intergral fly-screen.
Products are robust enough to be used with any roof tile regardless of the profile and can be fitted with plain tiles or slates.
