For ceiling in basement do you need the ceiling drywall to eliminate sag or is regular ultralight drywall ok?
Hi this is Matt with Property Inspired Construction
Dependent on the joist spacing both would be fine, we always try to get the biggest sheets we can into a basement on the ceiling to eliminate un needed joints, so when using longer sheets ceiling board or even 5/8 is much nicer to work with.
Ceiling board and 5/8 will give some minor deadening qualities for acoustics too, ultralight basically nothing as is much less dense.
Ultimately they all finish the same we use ceiling board generally because we are dealing with 12 & 14 ft sheets as much as possible.
