Wavin Osma StormLine

Choose OSMA StormLine when you require a higher capacity domestic system with a classic ogee shape or when you want clean attractive lines around the roof perimeter or conservatory.  Available in Black and White colour options.

High capacity domestic ogee profile

The high front edge of the gutter ensures the safe capture of high volumes of roof run-off under storm conditions. Even under extreme conditions, with unusually high run-off rates, the StormLine edge profile and internal ribs will quickly bring rainwater under control and guide it efficiently to the outlet.

Choice of downpipe

You can choose either Wavin OSMA 61mm (SquareLine) or 68mm (RoundLine) circular downpipe systems to use with the StormLine gutter to achieve the ogee look you require. No adaptors are needed. Concealed socket on fittings hides downpipe cut ends.
