If you have a room on the second floor that is larger than that on the first, you get an overhang: cantilever. While this is aesthetically pleasing and adds an interesting look to your home, it needs to be insulated. With little or no insulation in this 2-foot overhang, the outside air can easily carry cold winter air under the floor boards, making your floors and that room colder than others. It ultimately creates a cold bisection of your home. Call Dr. Energy Saver for home insulation in New Castle, DE and all surrounding areas!
