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.
