My contractor wants to screw metal stud horizontally to underside of joists and install dbl five eighth drywall to it. I want suspended channel and lathed u bar. Which way to go? I am a carpenter with yrs of both metal and wood structure.
If money is no object, suspended channel with perpendicular u-bar is the best method. When done correctly, it will guarantee a perfectly flat and level ceiling. Where as screwing furring channel will simply follow the existing joists, which are generally not perfect to begin with. Now, with that being said, suspended channel and u-bar is approxamitly three times more expensive. It requires additional labour and materials vs. furring channel.
Hope that helps.
I agree with Fred, in that it comes down to cost and how perfect you want the ceiling to be. Another oprion is simply a dropped ceiling with ceiling tiles. This method is good for sound muffeling and ease of installation. Food for thought?
First question, why double 5/8?
If your trying to minimize sound transfer, we recommend
-roxsul safe & sound in the ceiling joist cavities then,
-resilient channel instead of furring channel or strapping
-"Quiet Rock" 5/8 drywall .. with a sound rating of 55 or better.
Now if it's for a legal basement apartment, the drywall will need to be fire rated.. not all 5/8 is. You will need to show proof to the inspector of the rating, either the invoice or the back of the drywall with the code/stamp.
