Iron gas piping being installed.

After the vapor barrier is sealed, the walls and
ceilings have 1 x 3 strapping installed.

The interior wall framing is nailed to the
strapping. Note that the vapor barrier is complete
behind the interior petition and the strapping.

The next series of photos shows the installation of the
ventilation ductwork for the air to air heat exchanger

All seams are carefully taped and sealed

The ductwork is concealed within the house
frame. It gently and quietly distributes fresh air
to bedrooms and living areas while removing stale air
from bathrooms, kitchen, and laundry areas.

Careful routing of the ductwork means the system is
almost invisible, yet it consistently keeps the air in
the home fresh and healthy.

Central vacuum piping is installed at this stage.

Placing mortar under a tub gives the bottom a solid
feel and helps the heat from the radiant floor reach the bottom.

Electrical wiring is done at this stage. Note the
electrical box is in front of the vapor barrier secured
to the strapping. This keeps the boxes from leaking air
or moisture. A quality detail rarely employed by other builders.
