Katerra is one of just three CLT manufacturers in North America to receive Declare Labeling from the International Living Future Institute. Katerra’s CLT factory has received Chain of Custody (CoC) Certification under three major certification programs: Sustainable Forestry Initiative®, Forest Stewardship Council®, and the Programme for the Endorsement of Forest Certification.


Katerra has invested over two years of focused effort into the development of our mass timber product and manufacturing process, undergoing substantial independent laboratory testing to ensure Katerra cross-laminated timber (CLT) meets and exceeds the requirements of the International Building Code in the US and the Canadian Building Code in Canada. Learn more about this extensive testing – including strength, fire safety, acoustics, and more – in our new CLT performance testing video and white paper.
