Osma Rainwater Range - The Science of Drainage - Guttering systems
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.
Plus 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. Available in a range of six profiles for domestic and commercial applications.
