Upon hanging the TJI insulation cavity, the vapor open Weather Resistant Barrier (WRB) was installed and all seams were taped. Given the pressure of the cellulose that will be blown-in behind this WRB, we decided to use Solitex Mento 1000 and taped with our favorite Tescon Vana tape.
The next layer is the ventilation cavity / rainscreen / furring strips. We decided on horizontal with vertical furring strips to keep the cellulose bulge in check and maintain an acceptable ventilation cavity as well as provide a more substantial nailing surface for our engineered wood siding.
