Drywall is the most common wall material in homes throughout the country. It’s easier and cheaper to install than the previously used plaster and comes with numerous benefits.
Since drywall is mostly gypsum, its high water count results in a somewhat fire-resistant material. Plus, gypsum can be mixed with other additives and combined with special paper to create mold, mildew, and water-resistant walls.

What Are The Raw Materials In Drywall?
The main component of drywall is a mineral called gypsum. Gypsum has many uses, including fertilizer, plaster, chalk, blackboards, and of course, drywall.
Gypsum is used in drywall and sheetrock because it’s lightweight, easy to cut, non-combustible, and because of its high water crystallines, it is also fire resistant.
Before becoming drywall, gypsum is heated and reduced to a powder form known as plaster of Paris. Then, manufacturers mix additives into this powder before turning it into drywall.
The other main component of drywall is paper.
While there are different kinds of paper on wallboard, it almost always comes from recycled newspapers. Sometimes manufacturers add foil paper to drywall for a water-resistant surface.
