Got my crawl space dug out so I can move around. Want to insulate w/ R19
bats. Joists are 2x6 approx. 24 inches on center. What's the best way to
hold up the insulation? Can't staple the flanges since they need to face
up
towards the heated surface. Can't use the "wire struts" since the 24" on
center is only approximate. (± 1/2 inch). Was considering cutting strips
of Mylar and stapling them to the studs under the insulation.
The -1/2 is no problem, but if the spacing is over 24 those wires
don't hold well. How about stapling chicken wire across
perpendicular to the joists?
No matter how you put them up, you need chicken wire with small openings
stapled over the insulation to keep small animals out as they love to nest
in accessible insulation. The paper flanges won't keep anything out. They
can make quite a mess.

Hmm, he's talking about a ceiling I think. Wouldn't gravity discourage
nesting?
Mice and bugs and spiders and such, will happily nest in overhead
fiberglass. It easily supports their trivial weight. As long as they
have a non-slippery path up there, they will move right in. I found wads
of fiberglas in the drawers of this desk, where the mice carried it on
their way upstairs since they were passing through the crawlspace.
