I love Prodex Insulation: I bought a lot. I have insulated over ½ my attic with it. I also bought the double stick tape from Insulation4Less along with the foil tape.
Here is what I think about installation – it is easy. I had fiberglass insulation with a poly vapor barrier covering the insulation and rafters. I stapled the poly to the rafters and slit the poly between the rafters so as not to trap moisture. I ran the double stick down the poly covered rafters and then applied the Prodex Insulation. What I learned: the Prodex Insulation ideally should also be stapled through the flange into the rafter to help hold it tight. This not only helps prevent it from pulling away from the double stick tape, but also helps the foil tape seal the seams without the 2 runs of Prodex Insulation pulling apart from each other.
It is a great product. I can feel how much warmer the attic is each time I go up and the beetle infestation which used to come with winter has been significantly reduced – over 90%. Thank you Insulation4Less.
