475 High Performance Building Supply
Specialty building materials and technical support for airtight, vapor-open construction.
What they're known for
A US supplier connecting builders and designers to European and domestic high-performance envelope, ventilation, and natural-material systems.
475 High Performance Building Supply is a specialist supplier and technical resource for Passive House and high-performance construction in the United States and Canada. Its catalog includes airtightness membranes and tapes, wood-fiber insulation, ventilation systems, skylights and other building-envelope components that are difficult to source through conventional distribution. For Compound, 475 is important as an ecosystem node: it connects products, project teams and construction knowledge rather than manufacturing a single proprietary system.
