We are excited to contribute to this ambitious project by the City of Bridges Land Trust. This partner has planned to install both a heat pump water heater and a ductless heat pump for the finished attic.
E3 proposed adding interior wall insulation to this double-brick home. Framed walls also facilitate new whole-house electrical rewiring, while 2 inches of Polyiso foam board sealed around the perimeter add R-13 to the wall.
Detailed plans were also developed to improve the attic knee walls, including adding rigid foam behind the knee wall insulation, sealing the floor joist gap below the knee wall, and adding vents to these sections of the finished attic.
Additionally, this home will receive a triple-pane windows with a U-value of 0.2, SHGC of 0.24, providing approximately 50% better performance than a typical window.
The work is progressing quickly!
