VENT Ridge Vent RV10P

The VENT Ridge Vent is designed to release warm air from the roof void using the natural convection of rising warm air or by means of negative pressure created by wind blowing over the roof. The RV10P has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof. 

The RV10P form part of a passive ventilation system that works year round with no moving parts or energy consumption.

The RV10P is designed to be compatible with roof cladding profiles with a trough depth of <38mm.
