475 High Performance Building Supply, an ecommerce-based North American distributor of ecological building materials, has achieved the Declare building product transparency label for Pro Clima™ airtight tapes and membranes essential in the construction of high-performance and Passive House buildings. The Declare label aims to transform the marketplace through transparency and open communication by serving as a voluntary ‘nutrition-label’ for building materials. Declare integrates with the Living Building Challenge™ by providing product ingredients in support of the program’s Red List and Appropriate Sourcing Imperatives, streamlining material documentation and project certification.

Green Hammer, a unified design-build firm based in Portland, Oregon, used Declare-labeled Pro Clima products on its recent Cowhorn Vineyard & Gardens tasting room project, which is pursuing Living Building Challenge Petal Certification.

"We believe in using healthy, high-performance materials in our buildings," said Stephen Aiguier, Green Hammer CEO. "The Declare label provides quality assurance and transparency, giving us and our clients the peace-of-mind that our buildings are safe and healthy for people and the planet in every aspect of their extensive life cycle."

With the initiation of the Declare label, these Pro Clima products meet requirements for both Living Building Challenge and Passive House certification, two of the most robust and stringent green building certifications. Alexandra Batzer, Living Building Challenge project coordinator for Green Hammer adds, "achieving the Materials Petal for Living Building Challenge projects is not an easy feat. Pro Clima's ability to provide product information, references, and technical support was invaluable in our quest to eliminate Red-Listed chemicals from our projects."

The Declare-labeled Pro Clima products - Tescon Vana airtight tape, Tescon Primer RP and Intello Plus airtight smart vapor-retarder; will each be on display at the upcoming Living Product Expo in Pittsburgh, September 16th-18th. The Expo, organized by the International Living Future Institute, is a groundbreaking new event that will bring together leading minds in the building product industry and showcase the growing movement of manufacturers and sustainability specialists pursuing game-changing innovations in product design and use.

More than 300 products from leading green building manufacturers have already been listed in the Declare database which can be viewed at Accepted products may display their Declare label on their products – signaling to the world their leadership position in the marketplace. There are over 70 different manufacturers participating in Declare, with products in 14 CSI Divisions.
