We're breaking down wall assemblies that work for IECC climate zones 1, 2, & 3, which are considered warm climates, taking into account common building practices, as well as the limitations that we face when building in these climates. As we learn more and more about the nuances of regional and local climates and their impact on our buildings and building materials, we can be left wondering what types of wall assemblies will actually work for our climate, without causing problems like condensation, mold, or premature degradation.
