Sustainably certified - You can build on STEICO quality

As a manufacturer of building products we are aware of our responsibility. It is particularly important to us that STEICO products are manufactured without harmful additives and that they make a lasting contribution to healthy living. Consistent quality assurance activities in material selection and production ensure that we continuously produce the highest possible quality and protect the climate for future generations.

In addition, our products are tested by external institutions and certified according to strict specifications:

ISO Certification

The production and development of wood fibre insulating materials are certified by the TÜV Süddeutschland group of companies with a quality management system according to ISO 9001:2015 and an environmental management system according to ISO 14001:2015.


The FSC® certificate (Forest Stewardship Council®) certifies that all STEICO wood fibre insulation materials are selected and produced with a view to protecting the environment and health for future generations. The products offer convincing functions and quality.

We are pleased that the excellent quality of our products is also regularly confirmed by independent parties such as the Öko-Test-Verlag. This allows you to be sure that STEICO products will serve you well not only today, but also for many years to come. 


The PEFC certification (Programme for the Endorsement of Forest Certification Schemes) sets high standards, especially with regard to sustainability and environmental compatibility. The programme ensures that more wood will continue to grow in Europe in the future than is consumed. The certificate certifies that STEICO only uses wood from responsible forestry to protect the forest ecosystem.
