475 is a mainstay of the North American Passive House industry, supplying high performance building components to many of the earliest Passive House projects in the US and Canada, and expanding rapidly with the exponential growth of the market over the past decade. The company was among the first to recognize how important customer education is in the Passive House space given the holistic nature of high performance building design and construction. To that end, 475 shares a trove of building science and how-to educational resources with the AEC community via the foursevenfive.com website and inperson and online trainings.

We sell air-sealing tape as a specialized and critical component in a complete building enclosure airtightness system (INTELLO), which is the foundation of a low-energy building. And low-energy buildings are essential to realizing our post-carbon future – mitigating the worst effects of climate change. So at our core, we are activists for a sustainable environment.

Consequently, 475’s mission is to supply essential materials, building components, and knowledge that will lead a transformation of the North American construction industry toward making durable high-performance, Passive House and zero-energy buildings.
