Abutment Ventilation System
PVCU components designed to provide high level ventilation for lean-to roofs at the apex abutting a wall.
The Marley top abutment ventilation system components allow continuous ventilation at a top abutment, equivalent to not less than 5000 mm²/m, for plain tile, profiled (single lap interlocking) tile and double lap slate lean-to roofs.
The system consists of PVCU ventilated ridge battens, filler units (unventilated fillers provide a dry fix solution without ventilation) and a lead flashing support strip.
