In part one about our East Coast design team manager Kyle Barber’s new home, we shared the beginning of Barber and his wife’s journey designing and building a legacy passive home that will ensure a safe life, free of harmful VOC’s and full of clean air and comfort for them, their kids, and generations to follow.

Recently, Barber and his team’s attention turned to “drying in” the home so that the slab and interior work could be completed. “The enclosure went up, then as soon as the roof went on, windows went in and we were dried in allowing us to do all of the layers for the slab.”
After closing the house in with a metal roof and high-performance enclosure (our weather resistant and vapor controlling open cavity wall system with 2X framing, 100mm layer of wood fiber continuous insulation, and pre-installed strapping), high performance windows shipped from Europe (supplied by Zola) were installed to complete the enclosure. Once windows were in, the concrete-free slab was able to follow.
With the concreteless slab, you have to worry about water and rain on the plywood subfloor a lot more since its sitting right on top of the vapor barrier and can only dry to the top side. For this reason, Barber says, “We had to wait until we were dried in to perform this work.”

Barber continues, “The biggest thing that happened since last time was, we installed the foam under the slab. We have two layers of four-inch EPS insulation, so eight inches total. This will be the only foam in the entire project. Gives us about an R35 below our feet.
