We pioneered the manufacture of cross-laminated timber (Kreuzlagenholz – KLH®, CLT, X-LAM) and have developed the product in cooperation with the Technical University of Graz in 1996. After many years of research and development, we opened our production facility in Teufenbach – Katsch in 1999 and have gradually extended it. We operate internationally which is why our large-formate KLH® solid timber boards are not just used in Europe, but all across the globe as wall, floor and roof elements in structural timber construction. KLH Massivholz GmbH is fully owned by Johann Offner Unternehmensgruppe, a traditional family business with a history of more than 250 years.
