PEFC and FSC^® certificates

Our company’s commitment to the sustainability of sweet chestnut forests is evidenced by the fact that all our forests have FSC^® and PEFC forest certification, which certifies that our timber is managed in an environmentally appropriate, socially beneficial and economically viable way. On the other hand, both MADERAS SIERO and SIERO LAM have the PEFC and FSC^® chain of custody certificates, which guarantee the traceability of the wood from the moment it enters the log yard to the final product.
