How strong is the adhesion to the paper backing of R38.

I just bought some 16x48 kraft backed R38.

I’m planning on putting it on the ceiling.

Instead of suspending a grid and shoving the batts on top, would the paper backing hold the weight of the R38 long enough for me to loosely staple fabric over it?

I was thinking of putting up furring strips every 16”, then stapling the batts in place. Before they fall down I would staple the fabric loosely from one edge of one furring strip to the next.

Or will the batts pull away from the paper before I can get the fabric in place?

Oh... I suppose I could just use a deadman to hold them in place!

I know it will look a little rough. But I will put up some nicer fabric and some trim and lighting once they are in place.

Edit: attached cross-section.

I decided to staple the fabric to the paper backing. Then I know that they won’t fall.

I cut the fabric for this one to be exactly 40 inches, and it ended up being a little tight. I made the rest 40-1/4 and they aren’t pretty, but there shouldn’t be any danger of compression.
