If there's foam inside the wall, the molly type fastener above is out.

Don't tell the 10 or so moly wall anchors I have had holding things up on my foam insulated walls since 2007/08. Those moly expanding anchors will IMO work just fine in foam insulated walls unless the foam is wood type solid which would way a ton anyway. That small expanding area in those moly wall anchors will push the foam out away and you've already made a hole the diameter of the wall anchor in the foam to start with.

Interesting. I would have thought the foam was adhered to the wall and using a molly would cause incremental separation.

Thanks for the correction
