Following the “perfect wall” understanding of building envelopes, the control layers (thermal, moisture, air) belong on the outside of the structure. This approach protects the structure which is completely indoors 365 days per year and will work in all climate zones. This video deals with basement foundations. The sub slab is not included in this video, but includes control layers there too. We will continue to post videos for the rest of the house later.
