A: Yes, they can be used for 1.5" foam.
A: Hello, I am sorry to hear you had a bad experience with this product. We have not had other complaints of this nature, however sometimes the heads can bend over, etc., if the hole is not drilled deep enough, reamed out enough, or drilled to the proper 5/16" size. If you did all these things and still had issues, please contact us to remedy the situation!
A: Depends on exactly what your attaching. Theses are RodenHouse fasteners. https://docs.wixstatic.com/ugd/d0b80a_ef62beaced1a4bda8d1056b4e7cf4e98.pdf rodenhouse-inc.com
A: I used 7 per sheet after using Loctite PL 300 10 oz. Foamboard Adhesive tube per panel.
