Project: Exterior Trim and Spray-Foam Insulation

General contractor Tim Berky is creating a new frieze board to match the existing board and molding on the 1890 Queen Anne Victorian project house.

Bob is joined by Jim Remick, of Nickerson-Remick insulation contractors, who tells Bob that closed-cell insulation is more and more in demand. Once rigid, the insulation forms a moisture, vapor, and air barrier, with a high R-value.

Bob meets with Don Schumacher (from NCFI), who explains polyurethane spray-on insulation. Applied directly to the back of sheathing, it swells to 25 times its liquid volume, creating foam filled with microscopic bubbles that impede air movement.

Bob looks on as general contractor Tim Berky clads the Queen Anne Victorian project house with clapboards, taking cues from the home’s original 1890s exterior.
