If you’ve ever started a home renovation or new construction project, you’ve probably heard contractors mention wallboard, drywall, and Sheetrock as if they’re the same thing. But are they?
While these materials often overlap in meaning, subtle yet essential distinctions can affect your project’s durability, cost, and finish. Understanding those differences will help you choose the right product—and avoid unnecessary expenses or installation headaches.
Let’s break down each term and uncover what truly sets them apart.
What Is Wallboard?
“Wallboard” is a broad term that refers to any large, rigid sheet used to finish interior walls and ceilings. It’s the umbrella under which other materials—like drywall, gypsum board, cement board, and plywood panels—fall.
Composition:
Wallboard can be made from several materials, including:
- Gypsum (common in drywall)
- Wood fibers
- Cement- or paper-based products
- Composite materials
Where It’s Used:
- General interior wall finishes
- Office or commercial partitions
- Basements or garages where moisture-resistant materials are preferred
Pros:
- Versatile and widely available
- Can be moisture- or fire-resistant (depending on type)
- Easy to install and replace
Cons:
- Not all wallboards are equal in strength or finish quality.
- Some types, like fiberboard, may not be ideal for high-humidity areas.
In short, wallboard is the general family name—it can mean drywall, plywood paneling, or other board-based wall materials.
What Is Drywall?
Drywall is the most common type of wallboard used in modern construction. Also known as gypsum board or plasterboard, it consists of a gypsum core sandwiched between two layers of paper.
Composition:
- Gypsum (calcium sulfate dihydrate) at the core
- Paper facings that hold and protect the material
- Optional additives for fire, sound, or moisture resistance
Common Uses:
- Interior walls and ceilings
- Finishing basements
- Creating partitions or room dividers
Advantages:
- Smooth finish for painting or wallpapering
- Fire-resistant and lightweight
- Affordable and quick to install
- Various types available: moisture-resistant, soundproof, and mold-resistant
Disadvantages:
- Not suitable for continuous water exposure
- Prone to dents or cracks if hit with force
When you hear a contractor talk about “putting up drywall,” they’re referring to the gypsum-based panels that form the surface of most interior walls in today’s homes.
What Is Sheetrock®?
Sheetrock® is not a separate material—it’s a brand name for drywall produced by USG Corporation (United States Gypsum). Over the years, the brand became so popular that “Sheetrock” started being used interchangeably with “drywall,” even though it’s technically a trademarked product.
What Makes Sheetrock Special:
- Manufactured under strict quality control by USG
- Consistent density and surface smoothness
- Often includes enhanced performance features (fire-rated, soundproof, lightweight)
When to Choose Sheetrock:
- When you want premium quality and warranty support
- For high-end residential or commercial projects
- If you need specialized panels (like UltraLight or Mold Tough varieties)
Pros:
- Trusted brand reputation
- Reliable quality and durability
- Easier finishing and less dust during cutting
Cons:
- Slightly higher cost than generic drywall
- Availability can vary depending on the region.
So, all Sheetrock is drywall, but not all drywall is Sheetrock—it’s like every tissue isn’t a Kleenex!

- Fire Safety: Fire-rated drywall (Type X) for garages and shared walls.
- Soundproofing Needs: Choose sound-dampening drywall for home offices or media rooms.
- Budget: If cost is tight, generic drywall provides excellent performance at a lower price.
