I need advice/confirmation of a residential wall assembly.
Wood-framed home, from inside to out: ½” drywall, 2×6 studs w/fiberglass or roxul, R-5 Thermo-Brace SIB (think ZIP System), either a mesh (Tyvek DrainVent) or dimple board (Delta-Dry), LP Smart siding.
I’m confused on what rainscreen to use (DrinVent or Delta-Dry). Not sure if I need a permeable or impermeable. Since the insulation board has an integrated WRB I don’t want to trap any moisture.
Thanks in advance for the advice!
