For the ceiling I considered drywall, but for many reasons ... quick, one-step & it's done, no sanding, no painting, ... no muss, no fuss, I decided to go with steel panels. Plus, I like the clean, sharp appearance of the steel.
I installed regular faced insulation in the ceiling as you can see in some of the photos. Don't know if the vapor barrier is required or not, but using the staple flanges on the insulation bats makes the installation easier.
The contractor that built the garage come back and do the ceiling installation. It took 3 guys two days to install the 10'-6" long J-channels and the 44, 14' x 3' steel panels. They pre-drilled all the panels before lifting them up ... these panels are not light and are awkward to handle. They must be aligned much more carefully than installing drywall panels.
I had the J-channel set out from the wall 1/2 in. to allow future drywall on the walls to slip up behind the vertical leg of the J-channel to ease future finishing of the top edge of the drywall.
Things to be aware of if you are considering a steel ceiling ... check with your local inspector before selecting steel vs. drywall for the ceiling. The steel has a Class A fire spread rating, BUT it does not have a fire retardant rating. There may be concerns if you want to finish a room on second floor of your garage for habitation. Also, the electrical work for all of the ceiling mounted fixtures is a little more difficult (you want to avoid the big ridges on the panels) and you have to be careful of the sharp metal edges cutting the wiring so cutting and trimming holes for boxes takes time.
So far, I'm very pleased with the results!
This garage is getting close to being usable! Lights and ceiling fans are next.
