The VENT Apron Vent Deep Trough
is a Polypropylene Vent which enables warm air to escape from the lower roof void or through the barge detail of a mono-pitch skillion roof. The AB20DT
has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.
The AB20DT forms part of a passive ventilation system that works year round with no moving parts or energy consumption.
The AB20DT is designed to be compatible roof cladding profiles with a trough depth of >38mm.
