Great Stuff 343087 26.5-Ounce Wall and Floor Adhesive
When you want very little expansion (that could push the EPS sheets apart) it is best to use GreatStuff Wall Floor Adhesive.
$7.99 + $5.75 shipping
I use three different types of foam depending on how much expansion
No expansion - Foam Adhesive
Small expansion - Foam Windows and Doors
Large expansion (and fire seal) - Foam Gap Filler and Fire Seal
