I have a partially finished basement in my townhome. The owner used 2x2 studs, so I can't use regular fiberglass insulation as it would be squeezed too tight. There is a plastic vapor barrier covering the exterior wall, so I don't need anything with an additional vapor barrier. Can this product be used in the wall cavity for insulation behind the drywall and next to the plastic vapor barrier on the exterior concrete wall?
Asked by: Ilovebirds
It could... but it is 2" thick, not 1.5". Check the thickness carefully at home and in store. A 1" thick foam (and add a radiant barrier, metal foil to get every little bit of insulation you can) may make assembly a lot easier. You could also stack a 1" and a 1/2" foam to fill the gap.

Is this product heat resistant?

I will be applying heat up to 300°F. Will this product withstand this much heat?
Asked by: Bucky
According to Owens-Corning, this product has a maximum service temperature rating of 165 F, so this would not be recommended. At least one study suggests that polystyrene degradation may begin as low as 200 C (392 F), but given the combustibility of this product, I wouldn't exceed the service temperature unless you know what you're doing--and if that were the case, you probably wouldn't be asking this question here.

will work on concrete walls and how do you make it stick

Asked by: big D
The product can be attached directly to concrete using an adhesive intended for foam applications, such as Loctite PL 300.

Strong and works great for me - but I didn't use it the way it's normally used; I used a couple pieces to create a simple separator wall in an apartment - on their own, covered with fabric.

Rated 1 out of 5 by from I don't like that it's scored I used this previously to build an insulation box for our whole house fan. I came back a couple of years later to get more to build a box to put over our attic door. Unfortunately, it is now scored every 8 inches to a thickness of about 1" so that it is easy to cut to put between studs. However, the scoring reduces the R value and makes it less useful for my purposes

Rated 4 out of 5 by from It's a great material! It's light yet sturdy, just a bit difficult to cut but very easy to handle (you can sand it, paint it, glue it, etc.)
