475’s mission is to lead a transformation of the North American construction industry toward making durable high-performance, Passive House and zero-energy buildings. We do this by supplying essential knowledge and critical building components to industry professionals. We excel because we offer best-in-class products, with a highly specialized focus, through peer-to-peer communication and launched on a business-to-business interface. We deliver our products in a timely manner from regional fulfillment centers and support them with intense attention to customer service, bountiful knowledge resources, and local on-the-ground support. The name “475” is a reference to the heat demand requirement of the Passive House Standard, 4.75 kilo BTUs per square foot per year. Passive House is the gold standard for high performance construction today.
