Rainwater Guttering
The Wavin Osma range offers a choice of six rainwater gutter profiles to meet the varying aesthetic, performance and installation requirements for all types of building, from single dwelling to large residential, commercial or industrial premises.
Designed to handle more rainwater
Wavin Osma Rainwater systems are designed to be installed easily, give outstanding performance and look aesthetically pleasing.
Features include hydrodynamic running outlets that can handle 30% more rainwater than similarly sized competitive systems. And all gutter fittings feature wide, retained seals providing a secure, watertight fixture with the flexibility to allow for thermal expansion with expansion line markings and a stopper to ensure correct installation.
Connecting gutter to fittings is also easy with the 'Flexiclip' jointing mechanism - as the clip is flexed rather than the whole component.
For an aesthetically pleasing finish, fittings have been engineered with concealed sockets to hide roughly cut downpipe ends. If installing StormLine, there is also a hidden hanging bracket option for a seamless bracket free appearance.
