Can I foam inside an insulated drywall wall without damaging the drywall or insulation?

Answer:

You can foam in an insulated wall and it should not damage the drywall or insulation, however insulation will prevent the foam from getting where it needs to go.  What are you trying to foam and what is your issue?  If you are foaming for termites, then you should not be concerned about foaming an entire wall void.  You should only be concerned about getting the foam near the wood and studs.  Typically when a company foams walls, they drill holes at the top of the ceiling on either side of the studs and foam down the stud from the ceiling.  This way you have gravity working in your favor and you are getting the foam against the wood which is all that matters.
