I'm getting ready to blow some more insulation in my 1950s ranch attic this weekend. My attic has about 10 inches of insulation, and I'm going to be adding another 15 inches of insulation to bring the value to R-50.
Prior to putting doing the insulation I sealed all gaps and spaces as best I could with Great Stuff. I went through five cans, and hopefully this will make a different of sorts. I'm wondering if it is safe to blow insulation on the gable sides of the attic, as I had a vapor barrier installed two years ago when I had Hardie Plank siding installed. As of now, there is no insulation along this area, and you can see down to the exterior walls in some places.
Any advice would be greatly appreciated. Peter
