Inside the walls of this efficient home, sprayer-applied sealant and judiciously applied spray foam seal seams in framing, at top and bottom plates, and around plumbing and wiring to reduce drafts and help keep bugs, pollen, and moisture out of the home.

A 93% efficient tankless condensing water heater is centrally located in conditioned space near most of the home’s low-flow water fixtures. A push button-controlled recirculation pump speeds hot water to the furthest taps to reduce wait times and water waste.

Raised-heel energy trusses increase the height of the roof over the top plates along the outer walls, providing easier access for crews to spray foam the top plates to the ceiling drywall as well as more space for the R-60 of blown fiberglass that will blanket the attic floor. Cardboard baffles will provide a clear air path from the soffit vents to the ridge vents of the vented attic.

Garbett constructed these production homes with 2-by-6, 24-inch on-center walls. With advanced framing techniques like two-stud corners, single headers, and drywall clips, Garbett estimates it is able to eliminate about 300 hundred studs per home, which provides space in the walls for another 120 cubic feet of high-density blown-in fiberglass insulation, increasing the wall total insulation value to R-23.
