Summary: had an addition built recently. Do to improper installation, an air handler dumped water in ceiling - which came down in a bedroom covering EVERTHING with blown insulation.
The project is still under warranty.
I'm sure the contractor will say just run the stuff through the washing machine, but I don't believe I'll ever get all that insulation totally out of everything.
Luckily the door was closed so the damage is confined to one room. Any thoughts or advice anyone?
