Blown-in insulation on open vaulted ceiling
I am had built with the plan to blow in insulation, and now that Im about to do it my mind is struggling with some physics.
I ceiling joist to the roof rafters with the help of an engineer to vault my upstairs bedrooms. This leaves me with a void of half the difference shown in the diagram attached. My question is will 5/8 drywall secured at 16″ on center handle the load of blown in cellulose? If the insulation blows in as shown by the shaded area there shouldn’t be any more than 18-20″ over an given area. My biggest concern of course is how this would settle over time.
Any comments on:
A) a better solution given that the drywall is installed and finished
B) reasons why this is or isn’t OK?
C) ways to aid in making a blown in installation most effective.
Thanks in advance.
