You might not know that your attic plays a huge part in keeping your heating bills down.  That's something that will be very important this winter as energy costs continue to rise.  Having enough insulation is huge.  In fact, it's the single most important thing you can do to cut energy costs and reduce greenhouse gas emissions from your home.  The experts at the Department of Energy say you need 19 inches in fiberglass batt insulation or 22 inches of blown insulation.
