K. Hoffmann GmbH
For over 40 years, we have been manufacturing high-temperature-resistant boards, pressed, and milled molded parts from Vermiculite.
Due to its special properties, vermiculite is particularly suitable as a lightweight insulation material and is characterized by its temperature resistance up to 1100 °C.
If you are also looking for a sustainable insulation material without health concerns, then contact us.
