How much does 5/8 drywall weigh?
Depends on what time of day it is. The drywall seems a lot heavier in the afternoon, than it did in the morning.
Yup... which is the number one reason that homeowner's don't realize what a super bad thing they're doing when they throw down some plywood in the "attic" and store tons of crap up there. The bottom chord of the trusses are nearly overloaded already with just drywall, insulation, and lighting fixtures.Trusses are engineered for 2 to 2.5 lbs sq/ft dead load for the ceiling.
