Years ago I remember blown insulation being a bit of a no-go due to compression over time and the inability to ensure consistency throughout a wall cavity.
Has this changed? Have insulation in installment methods improved? To this day I still recommend the standard pink batts between walls but I have an architect pushing toward blown (not sprayed obviously).
I have my objections as noted above, but if the technology is better now and the results are comparable, I’d love to know. It could save some costs in labor for the client.

I should note that I’m referring specifically to fiberglass, not cotton or newspaper.

Re: Has blown insulation improved?
I have Isover tests which show no difference in performance with a wide range of densities in the void. They also show that a full fill, 100%, no airgaps, is beneficial. So, full fill, lightly pressing against the boundaries, but not compressed, supported from sagging...
