Is your home as warm as you think it should be in the winter? One problem area that homeowners often overlook is right above their heads. Maybe you should check out your attic insulation.
Heat Loss Through the Attic
Heat loss can occur for a number of reasons, from leaking ductwork to cracks around windows, doors and foundation, or even insufficient wall insulation. One area where you may be encountering significant heat loss is right over your head, in your attic.
As we know, heat rises. When your heated air penetrates the ceiling and wafts into the unconditioned space of your attic, your home could be wasting energy at an alarming rate. By adding insulation, you can prevent that heat from migrating into the attic and being lost. The U.S. Department of Energy estimates that you can save 10 to 50 percent on your heating bill by ensuring your attic is properly insulated. In the summer, this insulation also helps keep cooling costs under control.
How Much is Enough?
Hiring an energy auditor is one way to find out how much attic insulation you need. Without professional help, however, you can estimate. Is your insulation level even with or below the floor joists? If so, add more. If the insulation is above the joists, it’s probably sufficient. Insulation should be evenly distributed, without low spots. Make sure it is spread evenly along the eaves.
Insulation is measured by its R-value, or its ability to resist heat flow. The higher the number, the better the insulation does its job. A general rule of thumb for attics is to insulate at R-38, which equals 10 to 14 inches, depending on the type of insulation.
What Type of Attic Insulation?
You don’t have to stick with the insulation that is already present. Add fiberglass batts on top of loose-fill, or vice versa. Adding loose-fill requires a blowing machine, which some home improvement stores rent out.
