From a carpentry workshop to a global player


Uponor today is formed from the European innovators of the past and its roots can be traced right back to the 1620's.

The company has its origins in 1918, with the first plastic pipes manufactured in 1965.

Over the following decades the company has grown through innovation and investment in new products and markets, along with strategic acquisitions and development, to become a leading supplier of plumbing, indoor climate and infrastructure solutions around the globe.
