The Knauf is one of the world's leading manufacturers of modern building materials with headquarters in Iphofen, Germany. Our range includes plastering systems, drywall systems, flooring systems, insulation systems, building chemicals and construction machinery and tools. The KNAUF dates back to 1932, when two brothers Alfonso and Karl KNAUF founded a family business to extract gypsum. Thanks to their courage, determination and business skills, only a year later they opened their first gypsum factory, giving rise to what we call the KNAUF.
