Philosophy & History


Sealing, damping, insulating and protecting – that is our passion

Individual projects need individual solutions. So we quite deliberately do not offer our customers prefabricated articles, but develop solutions specially tailored to their needs. The shape, appearance and function that a foamed plastic product has to fulfil, can vary immensely from customer to customer and from one project to the next. Our team is here to ensure your projects run smoothly. Together, we’ll design a unique product that really meets all demands. Our aim is to support and promote the success of our customers with our product and logistics solutions in the best way possible. To achieve this, no idea is too unusual and no challenge to great. 

Perfectly tailored technical foamed plastics in first-class quality

We set especially great store on quality and service. Only with products of the best quality can a company like ISOWA be successful for over three decades. And only if communication is reliable and successful in consulting, sales and delivery can we offer our customers the better solution. Naturally, we also see our responsibility for our environment and consequently an ecological material selection and the sustainable use of resources is also integrated into our solutions. Our team plans your production in precisely the right shape, in the right place and at the right time. 

The best thing about our services is that, thanks to our certified quality management system, we can guarantee documented precision manufacturing with demanding tolerances. That’s an extraordinary promise - and we will keep it!

Long-term success from dynamic logistics 

The focus of ISOWA is clear: we always allow the tasks of our customers to serve as our orientation. That means, besides meeting their desire for punctual delivery and precision manufacturing, we enter into dialogue with our customers to find creative solutions that will guarantee the smooth, maintenance-free operation of their machines and facilities (e.g. through optimised assembly techniques for automated production). 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! 

Three decades’ experience in foamed plastic engineering

Though ISOWA’s beginnings were small, it has, over the past 31 years, developed into a top, economically stable company. On an area of 25,000 m², 140 qualified and skilled employees work in sales, quality management, engineering, logistics, manufacturing and administration. Together we generate an annual turnover of some 22 million euros.

Right from the outset, we have been an owner-led enterprise with flat hierarchies. This enables our customers to benefit from short and fast decision-making paths. We are proud to be able to say that over 1,000 customers per year from the automotive, construction, industrial and building services sectors trust us to find the better solution for them.
