Knierzinger – another way of spelling quality and safety

About us

Our Group is made up of Knierzinger Industrieisolierungen GmbH, established by Philipp Knierzinger in 1998, and Knierzinger Industriegerüstebau GmbH, established in 2014 to perfectly supplement our insulation offerings. We are trusted for expert workmanship, innovative working methods and dependability at its best.

Fields we serve

We specialise in the manufacture and servicing of industrial insulations for the pulp and paper, chemical and steel industries as well as for power plants and waste incinerators. Fire safety partitioning solutions are another expert field we serve. And last but not least, we’d like to emphasise our industrial scaffoldings. This extra portfolio enables us to handle many projects as a single-source supplier who knows how to make optimised use of its resources.

The way we work!

We currently employ about 150 persons at our Marchtrenk (Austria) and Passau (Germany) sites. We are particularly committed to organising periodic repeat training in technical and legal matters in order to back up our known quality and safety mission by compliance with the applicable standards. Working with innovative materials and cooperating with dependable and notable suppliers warrants a constant level of service quality and customer satisfaction. . Ever since 2002 already, Knierzinger has been certified in conformity with EN ISO 9001:2008 and SCC (Safety Certificate Contractors).
