Larger version of "Great Stuff". When we renovate our potato storage
warehouses, we have custom applicators come in and spray 3"-5" on the
interior walls and ceiling. Any openings such as a ridge cap are "boxed
out" and left open.


Cost? ....for the larger version of "Great Stuff"?

My thought was "insulation netting" with wire run up and twist-tied to
anything available, then blow in some ...(wait for it) ...old newspapers
into the new attic space you've created.

That blown in stuff is cheap - around here they (give) you the blower, free!
