of R19 insulation. The vapor barrier shall be installed on the warm side of the
insulation. All joints, door frames, electrical outlets or switches and any pipes or
vents that go through the cellar shall be sealed to prevent air and moisture
leakage into the cellar. Concrete, rock, and brick are not insulation or vapor
