Well my house isnt insulated...well not the whole thing. My parents went ahead and insulated 1 room which is my weigh room.... while they changed the windows to dual pane, thats when we found out the hosue wasnt insulated. But my windows were replaced before that and my room was also painted. So we are trying to avoid removing the sheet rock and repainting, and also my room is on the corner of the house so two walls lead to the outside. We heard we can do this type of insulation where they make small holes between the 2x4's and shoot in insulation...any help on that and where i can find it? no look online and i dont know the name or if it even exist. help i'm coool!!
