We have been producing high-quality fireproof refractory products from our own raw material deposits near Nuremberg since 1856. Our stove refractory fireclay for tiled stove construction, inner tubes from refractory fireclay for domestic fireplaces and refractory fireclay cladding for heating inserts are valued in the whole of Germany and in bordering countries. We feel committed to the protection of our environment in a special way; we therefore burn biogas from a nearby organic waste disposal site in our tunnel kilns. Constant quality controls by our factory laboratory as well as by external centres for goods supervision are self-evident for us.
