Net Zero House

Achieving low heating loads starts with good insulation: Two layers of 2-inch EPS provide a nominal R-26 below the slab.

Advanced framing techniques like single top plates reduces thermal bridging.

Two-stud corners also reduce thermal bridging.

An exterior skin of foil-faced polyiso — with seams taped and windows tightly flashed — helps seal the shell and further reduces thermal bridging.
