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 Osma Rainwater Range - It Must Be Osma

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!
