Wallboard, gypsum board, sheetrock, and gypsum plaster are just a few of the terms people use to describe drywall. So, is it really the same thing as wallboard and drywall? What’s the difference between drywall and wallboard, if not?

Drywall is one of the many building materials used in construction. It is an outer layer of plasterboard panels that are used to obtain soundproofing and fire protection.

It is a perfect medium between plasterboard and studs. In this blog, we will discuss different types of drywall, differences between wallboard and drywall, and how you can use wallboard for soundproofing in your home.

What is wallboard?

Wallboard is a type of paper-backed insulation board. It’s used in construction to cover walls and ceilings. Wallboard is often used to improve the look and feel of a room.

Wallboard can be painted or stained to match the décor of any room. That makes it easy to transform the look of a space.

Wallboard is an affordable and easy way to improve the look and feel of a room. It’s also easy to install and requires minimal maintenance. That makes it an excellent choice for many households.

Is wallboard the same as drywall?



Wallboard and drywall are both types of sheetrock. The term sheetrock refers to the material used in building construction.

Wallboard is made from two sheets of gypsum board that are joined together with an adhesive. Drywall is made of one sheet of high-quality gypsum board that is sealed with a special adhesive.

While wallboard may be used for ceilings, drywall is more commonly used for interior walls and ceilings. This is because drywall is thicker and has greater structural integrity than wallboard.

The thickness of drywall allows it to absorb shock better, making it a more durable option than wallboard. Additionally, drywall can be painted or decorated more easily than wallboard, making it more versatile for different applications.

Overall, wallboard and drywall have similar applications and differences in terms of thickness, durability, and cost. However, the term sheetrock does not encompass all types of building materials, so the terms should not be confused with each other.

Wallboard vs. Drywall – Differences

The core material is the major distinction between wallboard and drywall. Wallboard sheets’ cores are composed of a variety of materials, including wood pulp, gypsum, and PVC; drywall boards are made only of gypsum.

The differences between wallboard and drywall are shown in the table below:

Gypsum, wood pulp, wood chips, sawdust, wood scrap, and PVC are all possible core materials for wallboard.The foundation of drywall is a combination of gypsum and two paperboards.
Wallboard, as well as its varieties and manufacturers, such as Sheetrock, is a generic label for many sorts of wall and ceiling paneling.Green board, blue board, purple board, common drywall, and other types of wallboard are all examples of drywall.
