Different one-part foams
I’m installing XPS/EPS rigid foam against my basement walls. I’ve seen and read on FHB using low-expanding as the adhesive to hold the foam on the walls. I’ll be framing a 2×4 wall in front of the rigid foam, so the adhesive only needs a moderate hold.
Great Stuff Window & Door is by far the most common spray foam I see. Its in the big box stores, Amazon, etc. I’ve put up a few rigid foam sheets in the basement as a test with the Great Stuff and the hold is fine.
However, I’ve come across another Dow one-part spray foam, Enerfoam, and it is also low-expansion. And unlike the Great Stuff Window & Door, the Enerfoam lists adhesion of rigid foam as one of its applications. The Enerfoam is a couple dollars extra per can, and I’ll be using quite a few cans before the basement is finished. I was wondering if anyone had an opinion if the price premium was worth it for was I was looking to do? Anyone have experience with both?
