energy efficiency

The walls of this house are 2×8 construction with dense-pack cellulose insulation (R-27), ZIP sheathing for the air barrier and 6” Roxul insulation (R-24) for a total insulation value of R-43.

The foundation for this passive house consists of a slab-on-grade with a thickened perimeter footing that is thermally isolated from the ground by eight inches of high-density, structurally-rated EPS insulation (R-38).

Here at TDS, we have a history of providing remodels and additions to clients that are more durable, environmentally-sensitive and healthy than conventional construction.
