Weatherizing Homes with Biobased Spray Insulation
Insulation improves energy efficiency
Often clients come to us with a home that’s already designed. They ask us to help them improve a home’s air tightness and thermal envelope. One straightforward solution is adding insulation. Spray foam is an effective insulation because it forms an air barrier around your structure — sealing and insulating in one step. Once it is sealed, the air inside can be controlled by your heating and air unit.
In this video, we show a traditionally-framed home. Instead of installing batted insulation, we chose a bio-based spray foam insulation. This insulation adds a superior R-value, breaks thermal bridging, and enhances the home’s air tightness.
The airless sprayer application doesn’t require any chemical propellants and as the material cures, it is free of all off gassing. This lends itself to a more comfortable and healthy home.

Maybe SPF would be OK in new construction, if a chemically sensitive is not exposed to the product until it’s completely cured. However, Air-Krete is completely non-toxic to both the the installer and the habitant, so if a builder can use Air-Krete, why not? Vapor barriers are not always necessary; sometimes you want the building to dry to the inside or to the outside, depending on the climate and the weather. Air barriers, or course, are all-important, as this video alludes.
