I will tell you that insulation made a 100% difference. It’s crazy. My heat doesn’t even turn on up stairs. The heat from downstairs carries up and just sits there. It’s crazy how warm the house is. I just wanted to let you know. It was once again the best thing I could have ever done to this house and my last one. It’s crazy when I can see the difference living here a season without it and now with it. Thank you!!!
