Can you use this instead of plywood on a 2x6 framed exterior wall? Or does it go on after the plywood?
Asked by: 1234
The answer is no, simply because it has no strength value holding siding on if you intend to lay siding on the 2x6 wall. This product its best for keeping moisture and condensation from building-up in walls.

what is the weight of 1 panel?
Asked by: bob
Maybe a pound. It's super light weight. If you are going to put in it a truck make sue you can tie it down so it doesn't blow out of the bed. Or pick it up with a vehicle you can put it inside (suv or van).

Looking to use this as insulation for a camper floor. Can it be glued and sandwiched between marine plywood and a polyply sheeting? If so, what kind of glue would work on all these materials? I was hoping to use a roll-on glue for complete and permanent adherence.
Asked by: Allan
I bet roll-on contact cement would work great. I would use two layers of 1/4" ply with Overlapping / staggered joints over this. It won't resist any point loads, like heavy footsteps near a doorway or at joints of boards. Distribute the loads as evenly as possible over this foam.

I am looking to finish our below grade basement (Wisconsin) and looking to install this product directly against poured concrete walls. Does this product retain moisture? It says its designed for basement insulation and that its moisture resistant, but I've read about other EPS products that ended up absorbing moisture (vs. XPS).
Asked by: JR
Because it is faced with a membrane, it should not absorb moisture from your walls. However, if you have significant moisture coming though your concrete walls, I would fix that issue first before applying insulation

Purchased this because the old windows in our bedroom let in more cold air than an open door. We cut these to size, put duct tape on the cut edges and fit them against the windows. Worked great and kept the cold out during the really cold days. Am now going to put these up as a ceiling in the shop I'm building.

Rated 5 out of 5 by from Great stuff...fun to work with I insulated my 6' X 12' enclosed cargo trailer every inch from top to bottom with this stuff, and was very impressed after I mounted a 5,000 BTU AC on the back door. It's like a walk-in cold storage freezer. lol The air condition unit now runs for approximately two minutes or less at every fifteen minute interval as opposed to nearly continuous 24/7. Sound proofing characteristics of this product are what I consider to be moderate to very good as well. As each panel went up I could notice the difference as it gradually eliminated an 'echo' throughout the trailer. Could not be happier. Excellent value per sheet. Fun to work with. I used a six inch 'utility scraper' razor blade to cut it up. :)
