My upstairs sits on 16″ deep fabricated trusses (from full 2×4’s) on 16″ centers. To insulate and soundproof, I am considering blowing cellulose into the space between the floors. I am using 5/8″ drywall screwed directly to the trusses for the down celing. Any ideas on what weight the ceiling (drywall) would carry? Will a full 16″ be too heavy? (once I open up the access and start blowing, why not a full 16″?)
