Brick veneer ranch renovation insulation

user-2014262 | Posted in General Questions on

I am considering upgrading a 1966 Virginia Power gold medallion ranch house. House is now insulated with Corning 3inch fiberglass insulation with foil vapor barrier. The interior is plaster which is in good condition. My thoughts are to overlay the interior walls with 1 inch foam insulation them add a interior wall insulated with fiberglass. I was wondering about trapped moisture and drying if this sounds feasible or is there a better way to upgrade insulation.

    I don't anticipate that you will have any problems due to your plan. That said, a brick veneer wall can always have problems with water entry due to flashing problems or a defective air gap between the brick veneer and the WRB -- so it's hard to guarantee that your wall will stay dry.

    You wondered whether there is "a better way" to upgrade insulation. I suppose there is always a "better way" -- but most plans are a compromise that include considerations of cost.
