50 years of environmental focus

OSO is one of Norway's first environmental companies with over 50 years of effort to unite people, the environment and industry. The environmental initiative in OSO started in 1956 with Reidar Braathen jr., who created "Scandinavia's most environmentally friendly company" (SCANVAC award). After 50 years of continuous efforts for both the internal and external environment, GRIP v/ Environment Minister Arild Hareide awarded OSO "Glassbjørnen" an honorary award for our environmental work. Thanks to the faithful trust of our customers, OSO has become a term for both hot water and environmental protection. Products with an extremely long life and the market's lowest heat loss are our most important contribution to the environmental account, in addition to a production without environmentally harmful emissions of any kind. Love for nature is the foundation for our environmental commitment, and the objective is the same as 50 years ago; PROTECT OUR BEAUTIFUL WORLD
