Every since I moved into John's house I've been telling him one of the bedrooms must not have any insulation. In the winter this room is always freezing and really hot in the summer. Well he decided to check it out. Low and behold we had no insulation in the attic and sides for this room. Not surprising since one of our neighbors riped a hole in one of his walls and they had no insulation. Of course all warranties are gone now. So they rented a machine to blow insulation in the attic today. Let's see how it goes this summer.
