we are currently remodeling a master suite. built some soffitts in the bath and after framing covered this with rips of moisture backing sheet rock
(green board). the building inspector came by today and told us not to use green board on the lid, problems with steam/moisture. is green board just a joke, why not use regular board everywhere? any other ideas on this?

I have heard the same advice from out drywall contractor. It seems with drywall, you never get the same answer, in terms or nails VS screws: to glue or not; 5/8 on ceiling; or how many screw to use. Our dw contractor nails off the perimiter then about 4 screws in field of 4X8 sheet.
So, I think the answers to dw questions are going to be different with each person you ask

*Mr. Bell,I guess I'm at a bit of a loss as to what you mean by "lid". Could you explain that for us?Ed. Williams
*I think he means the ceiling - the 'lid' of the room. (Am I right, Mr. Bell?)
*Greenboard not recommended for ceilings. There, same answer twice! You can use what ever you want everywhere else. GB is more moisture resistant. For kitchens and baths....I use PermaWhite paint. Formulated for high moisture areas. Jeff
*Godfrey,Care to make that thrice? Green board not for ceilings ... they say if it gets too damp, the whole sheet can let go at once, which can give you a tremendous headache. As opposed to regular drywall, which will sag and let go bits at a time - at least you know it's coming down long before it does.Geo.
*Typically (at least in my limited exp.) 1/2" rock is used on walls and 5/8" for ceilings. This being said, and considering that most doors & windows tend to be set up for 2x framing and 1/2" rock, what is the reason for 5/8" greenboard? It's readily available which makes me think it's used for i something...... Sam
*Read a manufacturers handbook....Specifically states not to use greenboard on ceilings...But most people don't read directions do they....Four times you have now been told you did it wrong...Now go read the book.near the stream,ajSide topic...Do you nail starter shingles on upside down and full or do you follow the printed on every bundle directions that state to cut tabs off and also the basic nailing directions to b nail just above the glue line not below it!?
*Aj, I didn't say anything about what I'VE done! I was merely commenting on this post and making an observation! As for starter shingles, well I like to start those at the ridge and work down. When that's all finished, I bring out the felt and lay it over the top of the whole works! Jeez!!! Sam
*aj:I followed the directions on the package, cut the tabs and installed in normal direction, nailed where the picture showed. Of course I have only done a shed and two garages..... I do not even play a roofer on TV!Frank
*Sam,Godfrey made the post and I was answering to him...not you!You apparently do not read well either?I am not calling you names, just observing your reading comprehension, so tell us a joke and lighten up...I am not Joe Fukcso...Love ya sammy...near the stream,aj
*AJ- I'm buying, see ya' in the tavern..... Stripping off the felt and startin' from the bottom... Sam
*Sam...Make it a Winter Lager by you...Sam Adams...near the stream and ready for a couple pints!aj (jerk for a day)
*5/8 drywall, either green board or not,is used extensively on commercial work.I have read manufactures's directions that permitted the use of green board on the ceiling if framed on a 12" center.Terry
*Customers frequently ask me about "green board", and why am I not using it. Now I certainly don't pretend to know everything, (I read Break time to hopefully learn something)but I never use greenboard.It's very important to use a primer/sealer before painting, and I use a small bead of silicone caulk where,say, the paint meets the tub. Moisture will ruin regular dry wall or green board equally. So what is green board for?Beats me. But I believe the answer is...near the stream...
*Green board has additives in the core to make it more resistant to moisture. These additives also gave it less stiffness and thus greater tendency to sag in horizontal ceiling installations.The mix has since been modified for better performance and today half-inch green board can be used with ceilings framed 12" on center, 5/8ths on 16" OC.
*Mongo...The problem is the frames are built on 16" centers here and are heading toward 19"...The green 5/8" isn't used enough here, so the supply houses will not stock it....The trades don't change there methods very fast around here.near the stream,aj
*No argument from me, aj...If someone wanted to use it on a ceiling, I'd recommend furring strips 12" on center and 5/8ths inch board.It'd only cost you a few extra furring strips, a few extra screws...I hate installing anything to the manufacturer's recommended minimums.
*Can you say commercial?
*That didn't make sense. I meant that 5/8 is for commercial.
