However due to its tremendous popularity people mislabel all sorts of drywall as sheetrock.
Difference between sheet rock and dry wall.
Sheetrock and drywall are made of flattened gypsum plates that are sandwiched between two heavy papers.
The difference is fairly simple as sheetrock is a name brand of drywall that is considered to be a reliable one that many contractors depend on trust in and use as opposed to more general types of drywall.
Think of it like this.
It is finely ground and then pressed in between two thick pieces of paper.
The major difference between sheetrock and drywall is that only the us gypsum company can call their product sheetrock no one else.
To refer back to the kleenex versus generic brand analogy sheetrock is a name brand much like kleenex and drywall is the same product just without a brand name.
All sheetrock can be called drywall but not all drywall can be called sheetrock.
Gypsum powder makes up drywall.
This creates a board or a thin sheet.
