Type X and type C drywall are designed specifically to be used in fire-rated assemblies. Gypsum is noncombustible. The gypsum used to make drywall is a naturally occurring mineral composed of calcium sulfate dehydrate and water. A couple more ideas to look into: the cost difference, type x has good structural properties, installation notes, and type c is superior in performance.
What are the different types of drywall?
Standard drywall, or whiteboard, is typically white on one side and brown on the other. Unfortunately, water damage can be a very common occurrence when you’re a homeowner. A couple additional items to look into: eco-friendly drywall, mold resistant drywall, paperless drywall, fire resistant drywall, and soundproof drywall.

Also, what is gypsum type X?
The most common answer is; • Type X gypsum wallboard, 5/8″ in thickness (“5/8″ type X wallboard”), is manufactured for use as one component of an assembly/system (such as a wall) where a fire resistance rating is required in a residential, commercial, or other structure by an applicable building code.
What does drywall tape do?
To Tape or not to Tape
Quick and Durable Connection. Perhaps the most important benefit of using the tape is that it can provide additional support to the most vulnerable part of the drywall. The drywall compound that glues the panels together and covers the seams is strong once solidified. Cheap and Flexible.

Fiberglass-mesh tape is self-adhesive, so it doesn’t need to be embedded in a layer of compound. This speeds up the taping process and ensures that the tape will lie flat on the drywall surface. It also means that you can apply the tape to all seams in a room before putting on the first coat of compound.
It takes usually a couple days to supply, deliver and hang the drywall for a crew. Less crew, longer time. A building inspector may need to sign off on that before tape and mudding depending on your area. Then it will take a day or so from there to tape and mud it, a few days of warm weather drying, another day of Sanding and recoating.
