2 stories above grade with attic and basement.

Wall Insulation Retrofit: On the exterior, the asbestos siding, installed in 1947, was removed to reveal the original wood clapboard siding. Two rows of clapboard were carefully removed. Holes were drilled through the wood lathe to allow for filling the above-grade balloon-frame walls with R-13 dense-pack blown cellulose insulation. The clapboards were replaced and the original exterior wood was restored and painted. Limited by the 2x4 width of the original framing, the walls achieve a value of only R-15 including the plaster walls and exterior wood clapboard.

Basement: The basement foundation walls are made of cut stone block and is are partially below grade. The rim joist cavity was filled with spray foam. However,though the stone foundation walls were left uninsulated. The basement is partially conditioned and used for laundry and storage.

Attic: The attic was converted from an uninsulated, poorly-ventilated space (vented with gable windows) to a cathedralized, unventilated space using open cell Demilec Sealection 500 spray foam, achieving approximately R-29. EcoSmart Insulated cellular shades are used on the interior of the windows.
