Customer Questions & Answers

Are these panels tongue and groove?

Asked by: Lou
No, they are square edges per the mfg. The pink DOW product is tongue & groove, but no foil backer.

Can this be used over a concrete slab? I am using 2x4 framing over the slab and then 3/4" plywood as the subfloor.

I would like to insulate the floor from the cold concrete. Also which side should the foil face?
Asked by: JeffM

Has anyone ever painted/made the green side more aesthetically pleasing?

We are thinking of using silicone to adhere this product to our facility's windows to reduce solar gain. The product would be used in visible areas throughout our building. Is there a way to paint or cover the green backer to make it look more finished?

I need this insulation or something very like it. No store within 100 miles stocks it. I see no way to request it. How can I get 20 sheets?

Can this Foam Board be used on the perimeter walls of a dirt floor crawlspace?

Asked by: Nancy
Yes, I did my crawl space and rim board with these panels. I glued them to the (DRY) masonry block walls. The blue side of the panel was glued to the wall and the reflective side faced the crawl (living) space. Used smaller pieces along the rim joist and even covered the upper sill plate. Spray foam all the corners and joints, then tape over the seams. Additionally, I covered the floor with a reinforced vapor barrier made by Tyvek. A less expensive alternative is a heavy duty sheet of plastic. It worked for me, but I recommend you check the building codes in your area of the country.

Can I use this product for interior insulation on already existing walls?

Hello, I have a very old apartment with no insulation, and its walls are exposed on the outside (there's no adjacent structure). I can only insulate the interior walls of my unit. Is this product good for that purpose? If yes, how do I set it on the walls (screw/nail/glue)? Thanks in advance.
Asked by: Sotos
Per the mfg, you may install this in between studs or faced directly to an interior or exterior wall. If you are facing to a wall, then nailing/screwing and gluing to the studs would be a good bet. The glue helps make sure the insulation doesn't pop off the wall if you over torque a screw or the foam starts to pull away from a nail head. The foil on this product is a radiant barrier. I'm not sure how that might come into play in your situation. If the stud cavities are cold, that may encourage moisture accumulation. That might just mean you have to install this product in the studs vs. over the studs with say fiberglass in between them. There is a lot of good information online. Better than you can get with one answer to your question here!

2 in. x 4 ft. x 8 ft. R-13 Foam Insulation is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from I used this to insulate a crawl space and the rim board of my home. Super Tuff-R has reflective ... I used this to insulate a crawl space and the rim board of my home. Super Tuff-R has reflective foil facers on both sides ( the blue side is reinforced) for exceptional durability and water vapor resistance. The other side is reflective foil to provide radiant barrier qualities. Typically, the reflective side faces the living space. Install a minimum of 1-1/2 inches of rigid foam insulation board for a vapor barrier and glue it directly to the exterior block wall. Use spray foam to seal all openings and tape all seams. The ground in the crawl space was covered with a reinforced vapor barrier. These panels do NOT lay flat. I made my own fastener to hold them tight against the wall. I used a 3" masonry screw, with a fender washer. You must consider your our area of the country and building codes, for the proper installation.

Rated 5 out of 5 by from Great in the basement Purchased a few sheets to be installed in the basement, it went directly against the basement wall after the wall was drylocked. This has a higher R value than the pink stuff and a few more bucks, R 13 rated, i believe becuause the commerical stuff has a reflective coating on both sides, but any additional increase in insulation value without decreasing the wall space.

Rated 5 out of 5 by from Outstanding I used this product when I bought a beer distributor to scratch build a walk-in cooler - the insulation quality is excellent. Think about a foam coffee cup about 1/8" thick and consider this product is 2" thick - I used this product along with the thinner 1/2" ones to fill the 3 1/2" space of a 2x4
