Question

ceiling joist size - 2x4 or 2x6 needed?


Hi, this is my 1st post here! Thanks in advance for any help!

Here is my situation: I'm finishing off a gameroom under my house and there is currently about a 9 foot ceiling from the floor to the bottom of floor joists with several pipes, plumbing, electrical, etc. attached to the bottom of the floor joists. I want to put in a ceiling @ 8 feet to hide all of that stuff - everything is within about 8 inches of the bottom of the floor joists overhead. The room is 14 feet wide by about 25 feet long. My question: Spanning the room in the 14 foot direction, can I use 2x4's or do I have to use 2x6's? Can I use 2x4's if I attach them to the floor joists above with strapping or 2x4's to prevent sagging in the middle and for extra support? The ceiling joists will just be for supporting drywall - no additional loading or storage issues. Any thoughts?

Thanks!

14' is too long for a 2x4 to span and not sag when you attach the drywall.

You are correct though, that you can add blocking to support the mid-span of the 2x4 from the existing joists.

Good Luck

As previously answered = yes. You already have the right idea.

That is the reason suspended ceilings were invented and used. Remember once you sheetrock that ceiling and you have a problem later on, you have to rip it out, patch etc.

Let me see. A nice Sheetrock ceiling. Smooth nice looking or wait I can get a wall mart ceiling. Come on if you finish a basement correctly you really do not need access panels ( maybe one for something ). But if you want nice looking and not make your basement feel, well like a basement drywall is the only way to go.
