Where to buy EPS insulation for a concrete foundation?
What brands are available for unfaced EPS insulation under the foundation slab? I’ve only found one option at Home Depot (Amvic Multipurpose High Density Insulation Kit R10).
I did a web searches using EPS foam board, but I’m not getting results on places to buy the unfaced foam. I’m obviously not using the right search terms so I thought if I had manufacturer names I could look up who distributes their products and find options that way.
