Welcome to our forum.
Trying to improve the insulation in my house..it is really inadequate. I talked to a company that blows in foam like they use in hot tubs. Has anyone done this? I asked about running wire later, and it is virtually impossible once the foam is in place. I was thinking that the foam might be a good choice in my attic since I have a whole house fan and the loose stuff would blow around...my other choice would be batting. I wonder though if the foam traps moisture from the living areas and would create problems if trapped between the drywall and foam. I have no idea of how much this costs..but the R factor is 20 in a 6 inch application. They are coming to give me an estimate next week!!
Vinny, my windows are relatively new and I made them pull the molding in several windows because I didn't feel they did a good job insulating around them. I am a PIA customer..As I have added on to my house, I have used 2X6 for the walls and the insulation is much better than the old stuff in my 2X4 walls. My big concern is in my attic and in behind the knee walls in the front of the house. There is something called "Cape Cod Syndrome" that allows heat from the living area below to be lost through the eves in the front of the house because there is no block between the heated areas and the insulation in the floor of the eves. I think the foam stuff would not only add the insulation, but also seal that entire area. When we built our house, the insulation crew had no clue of what they were doing. Instead of insulating the walls in my basement, they insulated the basement ceiling. Who knows if I even have any insulation in my attic floor :-/ !
