So far so good, just putting it up now. I’ll know more once it’s covered with drywall to see how well it insulates this previously uninsulated cinder block wall.

Measure before You leave HD
My 1/2" was about 1" short of the 96" it should have been. I was 25+ miles from the store and an exchange was not possible. I contacted the manufacturer and they told me to pound dirt. I have spent 10K in the last few months on DC insulation and the response was very poor. Measure first if you are not close to the store. 1" makes a big difference.
The photo shown is not the product. To get the vapor barrier they have a film on both sides.

Excellent insulation, easy to work with
We have used these boards for years - they are ideal to nsulate tight and irregular spaces, like in old post-and-beam homes. R-value for same thickness is higher than fiberglass/stonewool. 2" foam board provides R10, while fiberglass provides R13 for 3 1/2". Cutting is easy either on a table saw or scoring with a very sharp blade and breaking apart. Cost is high, so it makes sense to weigh the benefits.
