floor coverings

The various properties and classifications of floor coverings such as colour and light resistance, fire resistance, walking comfort as well as thermal insulation and impact sound protection place high demands on both the quality of the carpet backing and the fillers used in it.

We have taken these requirements as the basis for our quality standards in the production of tailor-made fillers based on natural calcium carbonate, which, thanks to decades of experience, have led to effective and optimally applicable product lines such as CALCITUFT®, FOAMCARB® and CALCIFILL ®.

In order to be able to provide sustainable products for the future, several CALCIFILL®  products are already included and certified in our range of recycled fillers, and more will follow.
