The department of energy claims that the average us home loses hundreds of dollars a year in heating and cooling costs. We are planning to use closed cell foam on the trunk line which happens to be suspended 4 5 ft above the attic floor to r 21. I am currently working on a project where increasing the duct insulation is essential but i am running into problems finding flex duct or duct wrap with anything higher than r 8.

Close to 25 of the energy you use to heat and cool your home disappears through leaky ductwork. Apply a long strip of foil tape along the seam in the insulation. Repeat to insulate the remaining ducts. 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.

To install preformed duct insulation start by disconnecting an elbow to expose the end of the duct.
