Yeah, that's what I'm thinking. The dust and any other material might pull off some of the foam, which would be unfortunate. The foil skin on the standard panel should provide some protection.

I believe the blue/pink panels are waterproof, and the foil skin isn't structural unless you're buying Thermax HD.

That's exactly my question - is there a reflective benefit to the foil skin which equals the improved R-value of the pink and blue stuff? Probably is, as the instructions I mentioned above all advise putting the logos inside, and the shiny foil outside.

If you think the material is suitable, why not try it and report back?
I think I'll go the safe route this time, unless I hear otherwise about the pink/blue cohesion issue.
thanks for the thoughts!
