Isoplus brand

For over 30 years, the Isoplus group has been developing, producing, and marketing pipe systems for district heating and district cooling and pipes for all types of industrial plants. The Isoplus group comprises several separate manufacturing and sales companies throughout Europe and employs over 1,000 people.

Every year, the Isoplus group delivers thousands of kilometers of preinsulated pipes in sizes ranging from DN 20 all the way up to DN 1200. The product range includes preinsulated pipe systems for district heating and cooling and steam and pipe systems for industrial use.

At Isoplus, much of our energy is focused on innovative product development to keep pace with market requirements, using the latest technology. We have recently boosted the capacity of our high-tech continuous production lines, where we make preinsulated pipes with a gas diffusion barrier. The gas diffusion barrier keeps heat losses low throughout the pipe’s service life.

Isoplus is a modern enterprise that meets all international standards and requirements in all areas – whether they apply to our products or the environment.
