Proper duct insulation is a major key to ensuring your home s energy efficiency. Purchase duct wrap insulation that complies with the 2009 international energy conservation code iecc standards that specify an r value of 8 for attic ducts and 6 for ducts located anywhere else. Secure the insulation with short strips of foil tape.

Apply a long strip of foil tape along the seam in the insulation. To install preformed duct insulation start by disconnecting an elbow to expose the end of the duct. Wrap the insulation around the duct and then pinch the seam closed.
