We founded 475 High Performance Building Supply with one primary goal: being a resource for professionals in North America who want to build airtight. Over the years we’ve worked with everyone from tiny-house enthusiasts in Southern California to the firms building the world’s largest Passive House in New York, and we’ve learned endless lessons on how to integrate strategies for long-lasting airtightness. The bulk of what we’ve learned is applicable to all buildings, regardless of size, shape, use, or type. Thanks to a deepening understanding of its value, and to advances in the energy codes demand for airtight building is growing. In this four-part series, we’re laying down our most important recommendations for ensuring building efficiency and comfort by employing sturdy airtightness strategies.
