    I was looking for 12-in x 25-ft Insulated Polyester Flexible Duct, with an R-value of 8. is the only hardware store that carries this in my area. It seems only R-6 duct was available at the other stores. I plan to update all the HVAC duct in my attic with R-8 duct supplies from . Thanks for carrying what I needed most, and when I needed it. I ordered it on line, and in a matter of days, it was delivered to my front porch.

    Installed 35′ of this R8 duct as supply runs in our double wide in Feb 2020. Quality appeared satisfactory but still has heavy plastic odor 4 months later 5/29/2020. New ducts may smell for a couple of weeks. This duct is still stinking 4 months later. Off-gassing of plastic is not healthy and here we are in hot Florida with smelly house due to this product…..not good. And we have been having strange allergies since. I am concerned that is duct is inferior and a major health risk to my family.
