There is nothing like a Net Zero Home build! The homeowners have made a statement about their new home being part of the solution for Climate Change.

This Washington State build uses the new 2×8 EcoSmart™ Stud with Flash and Fill insulation. Thomas Bristol with Purple FlatTop Architecture has specified Flash and Fill insulation in most of his builds. When Tom was introduced to the EcoSmart™Stud for this build, he knew it was the perfect improvement for the Flash and Fill insulation as soon as he saw it.

The big change now for this building is the effective insulation change. The chamber insulation remains the same at an R-39. With the EcoSmart studs, the studs now boast an impressive R-20, marking a 129% increase over the R-Value for a solid 2×8 at R-8.7.

When all insulating elements are added, the effective wall insulation for this build is about R-32.5. For all you U-factor people out there, that’s a 0.0307 U-factor for the wall system! That is a 120% increase over a 2×6 wall with R-20 fiberglass batts and a 60% increase over solid 2×8’s using Flash and Fill insulation.

Another benefit is the remarkable resilience of the EcoSmart™ Stud wall system. With a 3/12 nail pattern required for this build in the mountains for a design PLF of 450, the EcoSmart™ Stud wall system surpasses expectations with a 550+ PLF design value with fewer nails! This is achieved through the combination of the hybrid 6/12 nail pattern with the 3″ of 2lb closed cell spray foam in the chamber, which spreads out through the EcoSmart™ Studs, wrapping around them and spreading through the entire wall system. The whole main floor will be tied together as one complete mono block of 2lb closed cell spray foam and framing, ensuring unparalleled durability.

This is achieved with little to no waste in insulation material, making the EcoSmart Stud also an Eco-friendly solution.
