Need to put up new drywall. It had ceiling tile with furing strips. Can I use the furing strips for the drywall running perpendicular to the joices as long as they are even? Or can I run 2x4's sidways (like the furing strips for more support?)Or should I run 2x4's width wise and build a new ceiling, so to speak. Old house messed up joices, uneven,rotten etc. not enough rotten that i can't run something perpendicular to make it work.
Hope this makes sense.
