ISOWA – The better solution.

Philosophy & History

Long-term success thanks to dynamic logistics

For ISOWA, dialogue with customers takes top priority, because only if we see ourselves as a part of the overall process, can we find the better solution for each project. This way, we can build a relationship of mutual trust with our customers, to develop a stable, long-term awareness for potential optimizations of our customers’ products and logistics, while maintaining a flexible approach. We do more than just deliver the product ordered: our qualified staff offers an all-encompassing concept, managing the entire supply process from start to finish.  Your projects are our passion and we will inspire you to take innovative paths – let us show you just how passionate we are!

Four decades of experience in foamed plastic engineering

In the past 40 years, ISOWA has evolved into an internationally recognised company.

Together, we generate an annual revenue of around 28 million Euros.

We are proud to say that every year, more than 1.000 clients from the sectors automotive, construction, industry and building technology rely on us to find the better solution for them.
