Are you planning on tearing off the exterior walls or just doing a drip foam?
If the exterior wall is being stripped, now is the time for rigid foam to be put up prior to re-cladding the exterior.
The answers to #1 and 2 depend on location and climate.
Thanks for the reply!
I'm near Roanoke VA. The exterior walls will not be taken off. I know nothing about this foam, so take my comments/assumptions with that in mind - but...
I thought the foam would be sprayed-in via round holes - not unlike a loose fill insulation. The foam would expand to fill the cavity between the interior and exterior wall - creating the moisture barrier and insulation.
