Spray Foam Insulation



A two part urethane foam has been sprayed at key locations to add thermal protection and to seal the envelope.  The application has been made to the wood "band" in the crawl space and the "band" between the first and second floors.  Also, the under side of the roof and all of the soffit areas have been sprayed to completely seal off all air leakage to the outside.

HVAC Rough In




A 16 SEER variable speed split system elecrtic heat pump has been installed.  This is a high efficiency system whose controls monitor outside air temperature and bring in free heating or cooling when possible.  The mechanical ventilation is also necessary to bring fresh air into the ultra-tight building envelope.

Electrical Rough In


The 200 amp electrical system has been installed and all circuits wired.  We have also installed conduit that links the attic space to the crawl space and then to the main electrical panel.  This will allow photovoltaic cells and/or solar hot water systems to be installed on the roof at a later date with little disruption.  The house is in essence "solar ready" and can accept technologies that may become more affordable in the future.

Windows, Doors, Roof and Siding




The roof, windows, and doors have been installed and the siding is going up.  The roof color is as light as possible to reduce the home's heat island effect.  The windows and doors incorporate Low-E glass and argon gas to increase envelope performance.  The detail picture shows flexible DuPont flashing membrane installed to avoid seaming at corners.
