About this listen

Two great questions about wall assemblies. The boys dig deep, exploring all the variables to consider for both wall assemblies. And no big surprise: Much of the conversation is about how to get these three control layers right (water, air, thermal) and ALSO get the drying potential (vapor) correct.
