Attic Duct Insulation Wrap

Proper duct insulation is a major key to ensuring your home s energy efficiency.

Attic duct insulation wrap.

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. The department of energy claims that the average us home loses hundreds of dollars a year in heating and cooling costs. I have a single level home with big open attic it has blown insulation and very narrow crawl space but my furnace electric has the single return air duct running about 4 feet from furnace it is in lowered ceiling from bathroom to kitchen my question is can i use a flexible hvac pipe duct an d run a network to living room and two bedrooms. 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.

Close to 25 of the energy you use to heat and cool your home disappears through leaky ductwork. Wrap the insulation around the duct and then pinch the seam closed. To install preformed duct insulation start by disconnecting an elbow to expose the end of the duct. Secure the insulation with short strips of foil tape.

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.
