10SHEETROCK: Once your home is framed and wrapped, and all the mechanicals have been installed, the sheetrock is put in place to form the walls. Your builder will be able to assist you in deciding the thickness of sheetrock you want to use, and if you want to use screws or nails to fasten it to the studs and joists. You may also want to consider what type of texture and paint to use on your walls to achieve your desired effect.
