Today we started blowing the insulation into the ceiling and end gables of the house and garage. We also blew foam into the south facing framed wall in the basement. I contracted for 2 inches in all areas, which is equal to R14 insulating value. I was helping the contractor put plastic on all exposed surfaces that we did not want to get foam overspray. He sprayed 4 to 5 inches of foam into all end gables and walls as payment for my help, which brought the R value to 28 - 35. This has made a huge difference in the insulation effectiveness. After I installed the batting in the ceilings, which added another R factor of 38, I could open the windows and shades in the house at night, close them in the morning, and work in the loft all day and the temperature stayed comfortable.
