"This is amazing. It is 55 degrees outside and I have the heat turned OFF - and it is 75 degrees inside the house and it is not getting any cooler inside. I feel like I may not need the heat this winter with the new insulation. I have a new pellet stove, but I am afraid to use it because it will probably get too hot inside. I am truly astounded by how much the insulation work has made my house into what feels like a nearly passive house."
