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.

A range of gutter profiles

Wavin Osma Rainwater has 6 different profiles to choose from for residential, industrial and commercial.

The Science of Drainage

The big problem with traditional guttering systems is they’re just not as efficient as they could be. So the OSMA team have designed a comprehensive rainwater range suitable for every need.

- The advanced hydrodynamic running outlet has a unique wider aperture, capable of handling up to 30% more rainwater when compared with other outlets of a similar size.

- Extra wide seals allow for thermal expansion and provide a secure watertight joint.

- The innovative Flexiclips make installation easy and can be removed to adjust the system or clean a seal.

- The unique cloaking collar has been designed to conceal the down pipe cut ends, for a much neater appearance.

Overflowing with innovative and practical features!
