[Greenbuilding] friction & insulation batts

[Reuben Deumling]

The situation is as follows:
a ceiling with 7-1/4"x14" bays, 11 feet deep
car decking below, fir T&G flooring above, rough sawn 2x8s in between.

I can get Rockwool/Roxul batts that are the right height and will figure
out a way to trim them to the right width. My question is whether anyone
has a suggestion about how to devise a sleeve or baffle to reduce the
considerable friction all those rough sawn or at least not particularly
smooth surfaces will present to the batts being shoved horizontally through
those bays?
I expect to be able to access both ends for this purpose, which should
increase the options for friction-reducing aids.

Any ideas?

Thanks very much.

Reuben

Oh, and I nixed the blown in cellulose idea because of the challenges of
creating the necessary back pressure on a bay that deep/long. I'm sure with
a suitably devised baffle that I could gradually back out the nozzle & this
problem could be overcome, but it is not a large job (11'x12') and the
batts seemed easier.
