Our one-and-a-half storey home has an attic areas on each side, not just at the ceiling. What are they, and how do we insulate them?
These areas are called knee walls and to insulate them, you can place an R-13 batt between the vertical inner wall studs, followed by an R20x23 batt, nailed across, for R-32 total. To provide a total seal, we suggest spraying the wall areas with icynene foam insulation. The floor areas in the knee walls should then be blown with loose insulation to minimum code or better.
