Our company history

Since the commercial agency for pre-insulated pipes was founded in Bavaria in the early 1970s – at the time with another name – ISOPLUS has always continued to grow. 

Technological innovations and sustainable growth 

Our commitment to innovation and quality is reflected in our continuous technological development. The introduction of highly modern pre-insulated pipe systems and highly diverse services, from the planning and design and project management through to installation and surveillance, have enabled us to offer energy-efficient solutions for district heating and industrial applications. This integrated approach makes sure that we can offer our customers tailored, individual solutions.

This is a central component of our mission, to promote sustainable and environmentally-friendly solutions.  

Europe-wide expansion and global presence 

In the meantime, we employaround 1,600 people in nine production locations throughout Europe. Together with our sales offices, we are represented in over 30 countries and are the European market leader in energy-efficient pre-insulated pipe systems for transformative and sustainable energy solutions – for millions of households, cities, municipalities and utility companies worldwide. 

This strategic positioning enables us to ensure short delivery routes and to always be local and near our customers. This proximity to our customers and markets is an important part of our success. 

En route to the future  

With the acquisition of a majority holding by Egeria in 2022, we made a significant step in the direction of further expansion and strengthening of our market position. This partnership helps us to realise our vision of green heat in Europe and to further expand our leading role in sustainable energy solutions.  

ISOPLUS stands for 35 years of innovation, quality and enduring growth. Our success story is shaped by technological breakthroughs, key partnerships and tireless striving for excellence. Together with our customers and partners, we look ahead to a sustainable and energy-efficient future with confidence.
