For location on prepared ridge and hip configurations. Two-part system consisting of dry-fix roll-out ventilation membrane with corrugated flashings to both edges. Integral adhesive strips to underside of flashings initially hold in place prior to placement and securing of ridges over the membrane assembly using mechanically fixed flexible moulded retaining gaskets. The flashing section of the membrane can be trimmed back should smaller ridges be deployed. Provides ventilation at high levels to satisfy statutory requirement.
