FSC® Certified Wood


Kolbe has been granted Forest Stewardship Council® Chain-of-Custody Certification, as have many of our distributors (FSC® license code FSC-C019541).

The FSC® is an international organization dedicated to promoting responsible management of the world's forests. FSC® certification ensures that the wood in products come from well-managed forests which meet the social, economic and ecological needs of present and future generations. Chain-of-Custody is the path taken from the forest to the consumer – including each stage of transformation, manufacturing, storage and transport involving a change of ownership of the material or product.  FSC®-certified products can contribute points toward certification for LEED®, Green Globes®, and other green building programs.

We're for the visionaries.®
