Frenzelit

What Frenzelit does

Frenzelit GmbH is a privately held, family-owned German manufacturer of high-performance sealing, insulation, and expansion joint materials, founded in 1881 and headquartered in Bad Berneck, Germany. The company operates across 7 international locations and a partner network spanning 65+ countries, employing 600+ people, with more than 50% of production exported worldwide. Its product portfolio is organized into four core categories: gaskets (Dichtungen, including the novapress, novamica, novaflon, novatec, novaphit, and novaform lines), thermal and acoustic insulation (Isolationen, including isoTHERM, isoGLAS, novaTEX, and the novaplan 03010 high-temperature insert), expansion joints (Kompensatoren, including the multilam and TEXRAIL lines), and the hicoTEC composite materials platform spanning thermal power, cleanroom/semiconductor, and fuel cell gas diffusion layer applications.

The company generates revenue through B2B direct sales of materials, semi-finished components, and custom-engineered finished parts to industrial and automotive OEM customers, distributed via wholly-owned subsidiaries (USA, Czech Republic, India, China) and a network of sales, service, and logistics partners. Pricing is quote-based with no public disclosure. Underlying technology rests on proprietary in-house material formulations and vertically integrated manufacturing processes (calendaring, dispersion, screen printing, wet-laid nonwoven, punching, CAD-supported engineering), supported by R&D partnerships with University of Bayreuth, Fraunhofer Institutes, TU Dresden, and other academic institutions. The customer base spans the chemical/petrochemical, automotive, food and drinking water, glass/steel, rail, shipbuilding, aerospace, and energy (including hydrogen) sectors, with named relationships including Audi (thermoREFLEX for the e-tron DC/DC converter) and Haberkorn (technical distribution in Austria). Recent strategic emphasis is placed on Zukunftswelten (future fields): hydrogen, electromobility, renewable energy, and fire protection.
