CMHC Sixplex Floor-to-Wall Air Sealing Mock-Up

We built this floor-to-wall framing mock-up to demonstrate building science, air sealing, and control layer continuity in timber construction. As the school year came to an end, we put our learning to the test by taking a detail from the CMHC sixplex and studying the control layers dutifully before building a scale replica of the connection. This quick mock-up provides a hands-on visual aid for explaining thermal continuity, vapor control, and airtight assemblies to fellow trades, clients, coworkers, and students alike.
