Abutment Vent – RV35
The VENT Systems RV35 Abutment Vent is specifically designed for long run metal roof claddings with trough depths up to 48mm. The Abutment Vents are designed to allow warm moist air to escape the roof cavity by means of natural convection of the warm air or by means of negative pressure created by wind movement over the roof.
The RV35 Abutment Vent is specifically designed to achieve ventilation on Parapet, Abutment and Mono-pitch barge details for roof pitches under 10°.
The RV35 comes with an adhesive and flexible aluminium flashing attached which is designed to form to most cladding profiles, preventing water ingress on any pitch roof.
