My son and I are building him a house, framing the walls with 2x6 studs and sheathing with 1/2" Advantec. The house is in a cold region and we're insulating the walls with 5 1/2" R21 fiberglass batts and 1" styrofoam bridging the studding on the inside walls (with 1/2" drywall applied over the styro). We'll caulk the edges of the styrofoam and seal the joints with tape. However, we're concerned that any moisture that may penetrate the stud bays will condense on the cold, inside surface of the Advantec, possibly leading to the formation of mold. Question: Is there a proven, relatively inexpensive, anti-mold construction spray that we could use in the stud bays prior to insulating that will inhibit the growth of mold/fungus over time? Is this step necessary?
