475 High Performance Building Supply

A leading source for knowledge and components used in high performance buildings.

About

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.

Sustainability & ESG Rating

We have a passion for building science, sustainable material use and Passive House; for protecting the environment and making the world a better place. We want to question, debate, and build consensus. Teamwork brings fun, and we work together - with urgency, to get the job done - across the United States and Canada.

When people ask what we do, one abbreviated response is: “We sell tape.” Though this describes a simple act, it is one with a potentially huge impact. 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.
