                   A HAPPY HOLDUP                         Mortar, move over. The Sanctuary’s base is comprised of
                   Charis used   -inch-thick, R-

 ICFs to form   insulated concrete form (ICF) blocks stacked like bricks,
                   the full wall height from footing to roof line   reinforced with rebar, and filled with concrete to form a
                   for the one-story plus full basement home.   sturdy, nature-resistant structure.

                     Footers were poured into a stay-in-place
                   form product that has built-in channels to
                   provide interior and exterior drainage of
                   the foundation. The -foot-tall basement
                   exterior walls were covered with a dimpled
                   plastic polyethylene membrane that relieves
                   hydrostatic pressure against the wall by
                   providing a pathway for liquid water to ow
                   down to the footing drains.
                     The  first-floor  ceiling  drywall  forms
                   the air barrier between the house and the
                   vented attic. To prevent air leakage, all

                           energy-efficient appliances and a
                           weather-resistant exterior are only
                           a few reasons this home’s owners
                           consider it to be their “Sanctuary.”
