Hi I'm in the process of remodeling an older home. The insulation in the loft
was removed, there was batting and blown, now it's time to re-insulate the loft.
I live in Arkansas winter temps sometimes 30 degrees, do I need the batting and
blown in my loft?
The type is pretty much immaterial; you need insulation of R30 at a minimum
If there's access/storage and/or you're thinking of doing it yourself,
the batting is probably much simpler to deal with as well as less muss.
If it'll be put up there and nobody is there for the next 20 yr or so,
getting it blown is possibly a little cheaper presuming decent access.
Here is Houston Texas sometimes 18 degrees,
It good to know that Arkansas is not getting to
-5 degrees winter temps as it did in the pass
But it's going to be a long a cold winter this year
More insulation or Wood or batting and blown
Dam it cool today

Depends on the sprayed area. If spraying the roof deck, open cell is
considered better due to the ability to allow water to pass "IF" there
is a roof leak. Open foam will allow the leak area to be detected much
easier. Once dry, open cell returns to it's normal state. If not on the
roof deck, then closed cell could still be considered, but in general,
closed cell is generally used for grade level or below because it serves
as a complete sealant barrier.
Closed cell used on roof decks will reroute a leak, thus making it
difficult to pinpoint the entering area. It also has a higher expansion
ratio and is recommended to be sprayed in new construction since it can
push out existing walls if not sprayed properly.
Overall, spray foam is the way to go, IMO.
