I have put up insulation and a layer of 3/4 osb on the walls, what thickness sheetrock should I put up to finish the walls off? Also what thickness should I use for the ceiling? I unfortunately do not have enough height in my room for a drop celing..



Thanks!

General rule of thumb is usually two layers of drywall, 5/8" over 1/2" or 1/2" over 5/8". (arguments abound for both)


Since you already have 3/4" OSB up I'd say the two layers of drywall might be overkill. Without knowing the acoustical properties of the 3/4" OSB it will be hard to recommend one drywall thickness over the other.


Doesn't look like I answered your question... :(


Hopefully someone with similar construction can give you some insight.

IMHO...


In looking at the size of the OSB (3/4") it would be best to put up 1/2".


The OSB is already close to the 5/8", so 1/2" would be a better bet.


Plus the 1/2" is thinner/lighter so it should be easier to "person" handle around the room. (I wanted to be PC on that... hahaha.)

Am I reading this right? You are putting the rock up directly on the OSB? If so I would suggest you not only screw the rock to the osb, but use some liquid nails as well. Its common practice for the double layer of rock install as well. It will keep any rattles from occuring. In fact I glued my rock to the studs as well. Better to do the extra work now and not worry about chasing rattles latter.

CV63,

For the record, it is less than ideal to use OSB. It is less dense and less effective than drywall. Best case scenarion is two layers of drywall.


In the OSB instance, I'd go with a layer, glued and screwed, of 5/8" drywall.

cv63 - try cleaning the lens...that's most likely the source of your white spots...if there's a little tiny spot on it, when the flash goes off it will create the "halo" effect that you're seeing....(probably drywall dust if you've been working in your HT lately :p)


Not to say you have a grimy lens, but even the smallest particles can cause that halo effect (try driving at night with water droplets on eyeglasses).


Cheers,


Rich
