Within each cavity we used several of the fire-rated Dow Froth Pak 650 kits… or, at least, we’re starting to. The first section we tackled was the kitchen area. Each stud pay is slightly over-filled. Once we are finished applying the foam, we will be shaving it down to ensure we have a full 3.5″ deep layer of insulation. Each inch of this stuff has an R-value of 6.6. Add in the R-value for 1/2″ OSB (0.51) and our final R-value, for the exterior walls and roof will be 23.61.
This is an in-process shot of the sitting area and wall behind the entertainment center. Like I said, we’re foaming every nook we can find.
