Use foam “fluff” as attic insulation?
A facility near me apparently cuts up a lot of XPS foam and advertises the remains on craigslist for free. They have huge bags of about 4″x4″x1.5″ chunks and others they refer to as “fluff”. They’re just very small, finely ground up pieces of the foam. Since this is free, I was wondering if the “fluff” could be used almost like cellulose in the attic or if the fact that it is no longer solid would greatly diminish its insulating abilities? Thanks for any advice.
