insulation for ceililng same as for walls?
I have my kitchen stripped back to the joists all around -- 1928 lathe and plaster off walls and ceiling. Obviously I'm going to install R-13 insulation in the walls (there wasn't any) and replace the fuzzy pink stuff that fell out of the crawlspace (fibers were great for my husband's allergies!)
Here's my question: can I/do I put the same sort of encapsulated insulation in the ceiling as I do the walls? We're having the house re-ducted, but it's not for another week. If the insulation for the ceiling can be same as what goes into the walls, I'll stuff it in now to keep as much dust up there as I can, then take it back down for the reduct, then put it back up pre-drywall.
If the insulation is different, or has to be installed from the top down (via the crawlspace) once the drywall is up, then I'll staple plastic up for the meantime.
Any help is welcome and appreciated.

insul.
You can use the same kind of insul. in the ceiling as you do in the walls, the
main difference is the thickness. The attic insul. is usually 6'' or 8'' or more,
depending on what part of the country you live in. Putting batts of insul. in
a ceiling on a temporary basis, is a lot of extra work! The thicker the insul.
batts, the more that their own weight will try to pull it all down, if you don't
plan to drywall the ceiling right away. Keep in mind that rolls or batts of insul.
are designed to be used in framing of exactly 16'' centers or 24'' centers.
The reason I mention this is lots of older homes have framing installed at
somewhat random spacing, and if so, makes them a better candidate for
a blown in insul. instead. You mentioned a ''crawlspace'', I think that in the
context of your question, you were referring to the attic. Actually, a crawl-
space is a subarea under a floor, in certain kinds of construction. I don't
say that to demean your knowledge of construction, it's just that if you use
these terms interchangeably, you may get some very confusing repies to your
questions. Good luck on this project.
