GREEN SEAL CERTIFIED
VINYL DOUBLE-HUNG WINDOWS

What does Green Seal certification mean?

Tyson Schwartz, of Gorell
Windows & Doors, explains
why homeowners should consider
Green Seal certified products.

The Green Seal says that a product or service has been tested according to science-based procedures, that it works as well or better than others in its class, and that it has been evaluated without bias or conflict of interest. The Green "Seal of Approval" has come to stand for reliability, fairness, and integrity.

Green Seal's evaluations are based on state-of-the-art science and information using internationally recognized methods and procedures. To earn the coveted Green Seal, a product must meet the Green Seal environmental standard for the category as demonstrated by rigorous evaluation, testing and a plant visit. The Seal provides a business advantage, for it identifies a product as environmentally preferable, provides third-party corroboration of environmental claims, and distinguishes a product from competitors that can't support their environmental assertions.
