If you can buy 25ft of insulated flexible ducting for $26....why wouldn't a person just buy that and remove the inner flex duct and use the insulating sleeve it comes with? I mean seriously...5 feet for 20 bucks?! Maybe I'm missing something?
Asked by: Steve
The price of the two products notwithstanding, metal pipe ducting has a lot less friction loss than flexible ducting of the same size.

Can you install this after install?

Can this go on after ducts are installed or must they go on before making the connections? In otherwords, must they slide onto the ducts or can they be wrapped?
Asked by: Smitty
You can install these after the ductwork is installed. It takes a little longer, but is designed with this in mind. The insulation has a natural seam - using sharp contractor shears you can cut the sleeve lengthwise along this seam. Then place the insulation over the duct and the sleeve over the insulation. You may wrap 1/2"-1" of the insulation over itself to minimize the air gap without compressing the fiberglass. I try to offset the seam in the insulation with the cut in the sleeve. Once the sleeve is generally in place use foil tape to secure both ends and the middle, then use long sections to seal the remainder of the seam.

Where is the 4in. Diameter duct sleeve?

I want the 4 inch sleeve for my 4 inch ductwork from the bathroom fan into my attic (the Maine winter is causing condensation to drip back into the house). I can't find it at anywhere.
Asked by: Hc
It seems that you could use the 6" sleeve if you cut the sleeve down the seam, wrap the insulation over itself (without compressing it) and overlap the sleeve before taping it. It will take a bit longer, but should be doable. I used 6" sleeves on existing ductwork, and slightly wrapped the insulation over itself to reduce the air gap between the insulation and duct.

Is this product waterproof, as in if a bathtub overflows and water leaks through the floor down into the basement and on to the ductwork, does the product need to be replaced?
Asked by: Lynn
No, it would not seem to be waterproof.

6 in. Dia R-6 Ductwork Insulation Sleeve is rated 3.7 out of 5 by 30.

The issue is that it is a sleeve, designed to slip over duct pipes. It works best if you are installing new ducts, or if you disconnect duct work to slide over the pipes. The suggested method for older pipes in use is to cut it lengthwise, wrap, then tape in place. This was the method I used for my old duct pipe that need insulating. What I didn't like is that the metallic layer is not connected to the fiberglass layer. Once you cut it, it wants to slide off because it's slick. So you are better off just buying a roll of normal normal insullation with an attached paper backing to wrap in a spiral pattern, or cut in short pieces and wrap/tape in place.

Rated 5 out of 5 by from Worked Excellent I wrapped the sleeve on the duct. I first taped all the seams, then did the wrap. I first did the two rooms furthest from the unit. Before the wrap, not so good. After the wrap, the air was coming out of the vents strong and cold. Product worked great.
