What is the difference between the green colored drywall, V/S the common white stuff? I stopped at a McDonalds and they are remodeling. I noticed they are using the green drywall throughout the whole building. I have seen that used in homes around tubs and showers, so I assume it is more waterproof. However, since they are using it throughout, is it more fireproof, or what? They are just using 1/2".
Besides application differences, what is the actual difference in the material the stuff is made from? Is the core still gypsum? Is the "paper coating" different (besides color)?
Thanks
