Drywall vs green board

[2000pstrokeblue]

So I have posted before but to recap, I have a 36x40 garage with 14 ft high ceilings. I'm finishing the insulation up R19 faced batts. My plan is to drywall the ceiling and top 5 ft of walls than plywood the bottom 8ft (the very bottom of walls are block). My question is do I use regular drywall or is it worth is to buy the green board type drywall. The joists are 24 in apart on the ceiling I plan on using 5/8 but I hear it's really not good to use green board for that span... Any insight would be appreciated thanks guys

Why not steel?

no green board on ceilings unless you are 12"o/c... You wont need it anyway you already have a vap barrier on the insulation...

I am not a fan of green board, see what it looks like hanging 24" o/c after 10 years and then you will not want to use it on your ceilings... It happens to be one of them "codes" that will save you and should not be ignored... I built a lot of houses, NEVER not once did I use green board to back tiles, I put a vapor barrier and cement board, do it once do it riht and sleep at night...

+1 for cement board. That's the right way to go.

Regular drywall.

Unless there is some requirement for fire resistance for the 5/8", skip that and instead put strapping 16" oc. Use 1/2 Sheetrock, install with go faster and easier.

Just my 2 cents.

Isn't green board used for moisture resistance?

How much moisture do you expect to encounter?

In my experience green board is moisture resistant and a little more expensive, usually used in bathrooms and kitchens where the walls are prone to moisture. I cannot think of any reason to use green board anywhere else other than moist locations.

If your bottom 1 ft of wall is block, you won't have any issues with moisture wicking up from the floor. Use regular drywall for the upper walls and ceiling drywall for the ceiling. It's lighter and fiber reinforced, likely not available at the box store, but any decent building supply should have it. Barring that, check the yellow pages under drywall supplies.

Not worth it- just use regular drywall.
If you want to add a bit of fire protection go with 5/8"X.

 

[boobag]

regular drywall is fine. 5/8 for ceiling.

you can buy paperless drywall if you are concerned about moisture.

So here there is regular, green and red.
Green is impact resistant and red is fire rated. Both have a level of moisture resistance.
Unless you are building to a required regulation they perform very closely as the green is also fire rated to some extent
Its down to cost really, i like using green or red in garage situations as its resistant to moisture and is considerably stronger if you need to fix to it, shelves etc...

As posted before, green is not suitable for ceilings, it sags badly. Use 5/8" type X fire resistant on the ceilings, it holds up much better. I usually use 5/8 on the walls also in a garage, it holds up to impacts without breaking much better. Not a lot more money, but a lot better resistance to damage. Texture it with a medium orange peel after taping, and paint with good semi-gloss paint. The texture and paint will make it much more resistant to scratching and denting, and will make it much easier to keep clean. Painting a good bright white semi-gloss will make your lighting infinitely more effective; getting enough good light in a garage makes it a lot easier to work in there.

Here 5/8 is required if it butts up against any living space. I put 5/8 on the ceiling (room over) and one wall where it is attached to the house plus the stair well. The rest is 1/2. It is for fire code. I have 1/2 on the ceilings above with no sag but they are strapped as described.

With two foot centers I would probably strap in the opposite direction every 16" anyway for more screw points and less sag no matter which thickness I used.

Here Green is just moisture resistant for bathrooms and such where there is steam and moisture. Regular sheet rock would be fine.

lightweight drywall. You won't have any problems with it. My main garage was built in '99 and I used drywall, and my addition I used lightweight drywall that is sag resistant.
