RV10DT – Ridge Vent Deep Trough

RV10DT - For roof cladding with a trough depth of 34mm to 48mm

Categories: ,

The VENT Ridge Vent Deep Trough 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 RV10DT has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.

The aluminium soft edge should be notched or snipped as required to suit the roofing profile. Notching or snipping is always required on Deep trough or trapezoidal roofing profiles.
