B.PUBLIC Prefab
Factory-built wall, roof, and floor panels for airtight, low-carbon residential envelopes.
What they're known for
A panelized enclosure system that moves insulation, air control, weather protection, and thermal-bridge detailing into a controlled shop before the structure reaches the site.
B.PUBLIC Prefab designs and manufactures off-site wall, roof, and floor panels for single-family and low-rise multifamily construction. Its assemblies use dense-pack cellulose, vapor-open control layers, and standardized details intended to reduce thermal bridging and field air-sealing work; published options range from above-code walls to Passive House-ready roof and wall systems. The company also trains installers so the factory-built enclosure has a defined path through site assembly.
