No, just a thin reflective foil. Looks like it's two layers of Polyethylene with vapor deposited aluminum between. It doesn't insulate by itself, just reflects IR back from the underside of the roof.

Missed your point on the styrofoam! I didn't know there was EPS that was able to take the load of an entire floor on top, that's certainly a great idea. In the end, you'll obviously want to have as...

Hey AC_Hacker - sorry for the delay in replying, I didn't get an email notification for your post.

I didn't measure the temperatures before and after insulating, but it's noticeable by feel. I...

I used a couple of screw guns and drywall screws (6-8 per plate depending on length) for my installation. It's not quite as quick as stapling, but still fast and easy to do - screwing the plates down...

Hah, good point!
