[Greenbuilding] PEX

[bilrob at silcom.com]

Test it first.
Take a piece of PEX, drill a hole in a piece of the material the PEX runs 
through and spray some of the foam on it to see what happens.

Do the same if you choose caulk.

I would be more concerned how you flash the penetration--how are you managing 
the moisture exposure?
