Kolbe® is proud to announce that we have been granted Forest Stewardship Council (FSC) Chain-of-Custody Certification, as have many of our distributors.
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.
Independent certification bodies assess chain of custody operations against FSC standards, review a company's qualifications, and award FSC certificates when operations are in full compliance. Certificates are valid for five years; however, according to FSC policy, the third party certification body must verify continued compliance. Kolbe has been awarded certification through Scientific Certification Systems, Inc. (SCS), which will conduct surveillance audits to reconfirm Kolbe's compliance on an annual basis.
Kolbe Products Available with FSC Certified Wood
FSC certified wood is an option on many Kolbe window and door products. Wood species available include alder, cherry, fir, mahogany, maple, oak, pine, walnut and other wood species. These products will be constructed using solid or edge-glued material, except for radius units. Note that some FSC-certified product may contain less than 1% non-FSC-certified wood components.
Standard and impact performance Kolbe products available with this option include:
VistaLuxe Collection windows and doors (wood interior / extruded aluminum exterior; contemporary design)

Kolbe will be happy to help architects and builders demonstrate their commitment to the environment by offering FSC-certified wood. By relying on certified architects and builders, homeowners can ensure that their project is built true to green initiatives.
