We start our building process by making a wall assembly mock-up on site. It helps us to practice our joints and junctions and allows the subs to see how our airtightness will work. The best feeling is coming back to the site and seeing others studying it to get the wall done right! For San Luis Obispo, a rain screen assembly is an awesome choice. The wall will get wet, so we have to give it room to shed that water. Careful planning of this assembly ahead of time made for quick execution on site!
