KLH MASSIVHOLZ GMBH is the pioneer, one of the global leading experts and with more than 25 years, the most experienced manufacturer of cross laminated timber (KLH® - CLT).

Our production facility in Teufenbach-Katsch, established in 1999, has seen gradual expansion. Two decades later, KLH commissioned its second production site, equipped with state-of-the-art technology and is therefore one of the most modern CLT production plants worldwide.

As a family-owned company, we see ourselves not only as a manufacturer, but rather as a project partner who, together with the local distribution partners, offers a wide range of technical services for sustainable, innovative and efficient building solutions.

Over the years, we have successfully delivered over 40.000 projects worldwide - ranging from small-scale single-family homes to groundbreaking wooden high-rise buildings.

We provide extensive technical services for sustainable construction and offer a wide range of software and tools. Our "KLHdesigner" online platform supports engineers and architects with tools for statics, building physics, and carbon footprint calculations - www.klhdesigner.at
