Spray Foam Insulation

Today was a pivotal day in the continued energy efficient retrofit of the Tucker Green Home. Spray foam insulation was blown in against the roof deck in the attic. As it turned out, a record high for the day was broken in Atlanta! (105 deg)

Bird Family Insulation was the contractor.

Here you can see the foam insulation that was sprayed in the attic. It's about 5.5" of open cell insulation sprayed against the roof deck. Open cell spray foam has an R value of about 3.5 per inch. So this is about an R-19 shown here.

Insulation was also sprayed against an interior knee wall in the crawl space.

The process took about 4 hours and cost approximately $2700.
