Looking for ceiling solutions with 2 feet of cellulose
I want to put a solid 2′ of cellulose in my attic of a new construction house and am thinking of running one layer of 1/2 drywall followed by 1 by 2 s run 1′ o.c., then another layer of 1/2″ drywall to carry the load.
I know some people use 1/2″ OSB or plywood covered in drywall or something else, but I ran the numbers and my detail is cheaper and it gives me a space to run wires without compromising my ceiling envelope.
Does anyone foresee issues with my detail? I don’t know where to look for loads of the cellulose and if maybe 5/8″ drywall with proper penetration sealant or some other cheaper solution can be used.
