Understanding Drywall and Sheetrock: What's the Difference?

Are Drywall and Sheetrock the Same Thing?

When discussing drywall, one term that often comes up is 'Sheetrock.' It’s common to wonder if these two terms refer to the same material. In essence, drywall is a generic term for a panel made of gypsum that is used as interior wall and ceiling construction. Sheetrock, on the other hand, is a brand name created by the United States Gypsum Company and is a type of drywall. Therefore, while all Sheetrock is drywall, not all drywall is Sheetrock.

Is Gypsum Board Drywall?

Gypsum board is another term frequently associated with drywall. Gypsum board consists of a core of gypsum surrounded by paper, much like standard drywall. It is often used interchangeably with the term 'drywall.' However, gypsum board can also refer to specific types of boards such as fire-rated or water-resistant boards designed for particular applications. In short, gypsum board is indeed a primary component of drywall.

What is Wallboard?

Another term to familiarize yourself with is 'wallboard.' Wallboard is a broad category that encompasses various types of wall panels, including drywall and gypsum board. Essentially, all drywall qualifies as wallboard, but not all wallboard meets the specifications of drywall. The term can also include other materials such as plywood and oriented strand board (OSB).

What is Gypsum?

Gypsum is the mineral that is the primary ingredient in drywall and gypsum board. This naturally occurring mineral is composed of calcium sulfate dihydrate. It is known for its fire-resistant properties and its ability to help regulate moisture levels in a room when used in wall constructions. Gypsum plays a critical role in drywall's performance, making it a sought-after material in construction and renovation.

Key Takeaways

In conclusion, understanding the distinctions between drywall, Sheetrock, gypsum board, wallboard, and gypsum itself is essential for anyone involved in construction or home improvement. Drywall is the broad category, while Sheetrock is a specific brand. Gypsum board and drywall are quite similar, with gypsum being the key component in both. Finally, wallboard is a more encompassing term that can include various wall materials. Having clarity on these terms can help you make more informed decisions in your home improvement projects.
