Energy experts agree that you'll lower your energy bills if you insulate your attic with at least 12-inches, which is considered the minimum amount to meet today's standards. And it's easy to do - just lay down batts of poly-wrapped insulation directly over what's already up there. It's not exactly fun to do, but it's one of the best ways you can button up your house to make it tighter and more energy efficient.
An insulation contractor will charge $984 to install fiberglass batts in the cavities and space between floor joists in a 1,200-square-foot attic. You can buy the insulation for $550, the cost to insulate an attic, and do it yourself and pocket a nice saving. Today's batt insulation is greatly improved and wrapped making it much easier - read: not itchy - to install. It's compacted so it's not as bulky and cumbersome to transport and get up to the attic.
To add attic insulation, use a measuring tape to determine the length of batts needed, scissors and a straight edge to cut them to size. Wear a respirator, safety goggles, long pants, a long-sleeved shirt and a pair of knee pads to save your shins.
