This project was developed in two stages. First, an entire renovation to the existing house built in 1953. We refurbished old rooms, dealt with lead based paint issues, and improved energy efficiency. Doors and windows were replaced, in addition to an old electric water heater that was switched to a Rinnai 735 gpm tankless gas model.
The original house had a flat uninsulated 2x6 ceiling/roof structure. The decorative plaster ceilings were in great condition, and were not in need of removal. Insulation was necessary, so we built up the roof with rigid foam boards, typically used on commercial roofs. They were covered with two inches of closed cell spray foam. By applying an acrylic sealant over the foam insulation, it provided a strong, walkable, roof surface in addition to a superior R-Value.
The energy upgrade was topped off by converting the vented crawlspace into a semi-conditioned sealed crawlspace. The kitchen was also renovated to include more energy efficient appliances.parapet with a scupper & leader drainage system. The addition maintained energy efficiency via closed cell spray foam roofing and open cell spray foam wall insulation, a sealed crawl space, energy efficient windows, and a low energy zoned heat pump system.
