Rated 5 out of 5 by from Easy to use - works like a charm I recently used this to insulate the interior of my basement. It went up easily. In fact, it went up so quickly that insulating the basement was the most satisfying part of the entire basement finishing project. When needed I trimmed with a utility knife before using adhesive to stick these to the cinder block walls. I did not think of my basement as cold before this work, but I noticed a difference immediately - it is now the coziest room in the house. I would use this stuff again in a heartbeat. I spent a great deal of time reviewing the various insulation options before choosing foamular XPS. So glad I made this choice. The combination of ease of use, effective insulation, and ability to use below grade made this exactly what I needed.

Rated 5 out of 5 by from Expensive but efficient I used this to muffle the sound of an inline fan on a false wall and it worked great. it's very easy to work with which is why i pay for it but on the expensive side for insulation.

Rated 4 out of 5 by from Misinfomation I needed to fill in a misplaced window. I used this product to insulate the outside. Since the outside of the project was inside my garage I asked the employee that was helping me if this product was paintable. I was told it was and used a waterproof primer/paint spray. It was melting the board. It wasn't major but I would recomend some sort of over boarding or paneling if you want to paint for weatherproofing. In all I liked the product's ease of instillation, and was impressed at the insulationing effect for my kitchen.

Rated 4 out of 5 by from Dood Stuff Does the job. I installed it on the underground walls of the basement. This winter my laser temperature gun showed room temperature on the foam and 5 to 10 degrees lower on adjacent uninsulated wall. I used 2 inch foam board on above ground walls with similar results.
