How to wrap ductwork with bubble wrap insulation

This video shows how to insulate sheet metal duct work with R8.0 bubble wrap insulation. The insulation is called Big Bubble by Reflectix. I show how to make the wrap last for 50 years without unraveling. The key is silver colored 3 inch wide rfoil metalized duct tape. When the duct work is exposed to attic heat, the tape should be covered with UL 181m water based mastic. Reflectix says to use 181p aluminum tape. But, I think the rfoil duct tape with mastic is better. Here is the link to the insulation: http://reflectixinc.com/basepage.asp?...
