I'm replacing the wall insulation in a free-standing one-room building
built in 1977. The studs are 13 inches apart, and the original
Kraft-batted fiberglass insulation is 13 inches wide. Can you still buy
13-inch wide fiberglass insulation anywhere?

And what about some of the other insulation options available, such as
polystyrene and Reflectrix -- are those worth looking into? Does
Reflectrix work on its own, or only in addition to something like
fiberglass?

Owns Corning comes in 15 or 23" wide. Foam board will work, but it comes in
sheets and has to be cut. If you need 13", you won't get that easily from a
24" or 48" wide board.

Consider the spray in foam. Probably will cost a bit more, but would do a
very good job.
