The core of revolutionary innovation

As a research facility, we at the Von Roll Institute provide you with expertise based on over 100 years’ experience in the insulation business. As well as other developments, we designed two revolutionary innovations: the flexible insulation material mica splitting and mica paper.

You can benefit from our experience by involving our team in the development of your insulation systems – including consultants, advisors, and researchers. As a result, you save time on development, reduce long-term costs of production, and increase the lifespan of your rotating machinery.

We look forward to collaborating with you.
