Over 100-years of expertise: Building a bridge from a successful past to a sustainable future

Uponor’s story began in 1918, when Aukusti Asko-Avonius established a carpentry workshop in Lahti, Finland. The workshop quickly grew into the largest furniture supplier in the Nordic countries. In the 1960’s, the company expanded its business further into the plastics industry.

Today, we are building a bridge from a successful past to a sustainable future. With the same innovative spirit that brought next-generation alternatives to concrete, iron and copper as piping materials, we are moving forward into ever-more intelligent solutions. With a focus on sustainability, we promote innovation in energy saving and smarter water usage for the benefit of our customers and the world we live in.
