PVC-U components designed to provide ventilation for lean-to roofs.
Suitable for use with all Marley concrete tiles and slates to provide high level ventilation for lean-to roofs at the apex abutting a wall.
Ventilation system components allowing continuous ventilation at a top abutment, equivalent to not less than 5000 mm²/m, for 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.
