the ceiling Im working on is 2x6s on 24″ centers with 1/2″ pine 1×3 furring splitting the 24″ roughly in center. It was lath and plaster, downgrading to gypsum. I think either upgrading the 1x3s to 2x4s or2x6s but that would be 12″ center 2x6s, does not seem worthwhile or dead load suited. Anyone agree a 3×5′ x 3×5′ crawlspace for storage needs one of these?
Like the custom trim thread, I’m blank with understanding what it is you are trying to do.
Old dumb carpenter with evidently no spatial intuition if there is that....
This is like one of those story problems with extra information you don't need to answer the question.
if it is a crawlspace, why finish the ceiling at all? (you could paint it with a sprayer).
How big is the area? is it 15 ft x 15 feet? How tall?
You can hang drywall into ceiling joists that are on two foot centers. My house second floor and garage are all that way. Drywall into the bottom chord of trusses.
If you want to support it better, you can run whatever size furring you like at right angles to the joists, if you can stand the slight lowering of the ceiling.
hey uncle mike. i was kicked off the canadian chat for not being a contractor. so now I just blast it out there, not really worried coz I guarantee some solution will happen no matter how stupid I come off. Anyway, your post made me wonder what the sag width on 5/8" drywall is when hung on the ceiling.
If it will be dry it will not go anywhere. just have to use some screws and get it on straight in the first place. If whatever was holding the lath in between joists is still there, you can catch it with a couple screws too, and even a bit of construction adhesive if you are so inclined.
Like I said, my house (built in 72) has two foot centers, and half inch drywall nailed up. The only place there are any issues is where water got to it.
Furring strips are my conclusion after considering the options. Thanks!
How about a picture?
