Difference Between Drywall and Sheetrock

Drywall, also known as plasterboard, gypsum board, and wallboard, is a construction material used to cover interior ceilings and walls.

If you’ve ever planned a home renovation or new construction project, you’ve probably encountered the terms drywall and Sheetrock. Many people use these words interchangeably, but subtle differences are worth understanding—especially if you want the best results for your walls and ceilings. As professional contractors, we’re often asked about the difference between drywall and Sheetrock, what each is made of, and which type is best for specific applications. Let’s clear up the confusion and help you make the right choices for your next project.

What is Drywall?

Drywall, also known as plasterboard, gypsum board, or wallboard, is one of the most common building materials used to cover the interior walls and ceilings of homes and commercial spaces. Before drywall became the standard, walls were constructed using layers of plaster applied over lath, a time-consuming and labor-intensive process.

Drywall revolutionized construction in the early 20th century by making wall and ceiling installation faster, more affordable, and more consistent. The drywall core is made from gypsum—a mineral called calcium sulfate dihydrate—pressed between two thick sheets of paper. The result is a sturdy, smooth panel that is easy to cut, install, and finish. Drywall is valued for its fire resistance, affordability, and versatility.

What is Sheetrock?

Sheetrock is a specific brand of drywall manufactured by the United States Gypsum Company (USG). Sheetrock was introduced in 1917 and quickly became a trusted name in the construction industry. Over time, the brand became so well-known that many people began referring to all drywall as Sheetrock, much like how people use “Kleenex” to refer to facial tissues.

Sheetrock panels are made using the same basic materials and methods as other drywall products: a gypsum core sandwiched between heavy paper. However, Sheetrock has built a reputation for quality and consistency, and the company offers a wide range of specialty panels with enhanced features, such as mold resistance, moisture resistance, and soundproofing.

The Difference Between Drywall and Sheetrock

The most important thing to know is that not all Sheetrock is drywall. Sheetrock is simply a brand name for a particular manufacturer’s drywall products. The materials, installation methods, and end uses are essentially the same.

However, there are a few differences that can matter in certain situations:

• Sheetrock is known for its high manufacturing standards and quality control, which can translate to fewer defects and easier installation.

• Some Sheetrock panels are formulated to reduce odors and not emit the sulfur smell that can sometimes be found in other, lower-quality drywall products.

• Sheetrock offers a variety of specialty panels for specific needs, such as fire-rated, mold-resistant, or sound-dampening drywall.

What is Drywall Made Of?

All drywall, including Sheetrock, is made primarily from gypsum. Gypsum is a soft mineral that is fire-resistant and easy to work with. The manufacturing process involves mixing gypsum with water and various additives to enhance strength, durability, or other properties. This mixture is then pressed between two thick sheets of specially treated paper to form rigid sheets.

Once dried and cut to size, these sheets are ready to be installed on walls and ceilings. The paper surfaces provide a smooth finish ideal for painting, wallpapering, or decorative treatments.

Types of Drywall

Several types of drywall are available, each with its unique features and best uses. Here are some of the most common drywall types:

Standard Drywall (Whiteboard)

This is the most widely used type of drywall and is a suitable option for most interior walls and ceilings. It is typically available in 1/2-inch thickness, but other thicknesses are available for specific needs.

Moisture-Resistant Drywall (Green Board)

This type of drywall has a special moisture-resistant core and paper facing, making it ideal for use in bathrooms, kitchens, laundry rooms, and other areas with higher humidity.

Mold-Resistant Drywall

Mold-resistant drywall is designed with special additives to inhibit the growth of mold and mildew. It is often used in areas prone to moisture and humidity.

Fire-Resistant Drywall (Type X)

Fire-resistant drywall contains glass fibers and other additives that increase its resistance to fire. It is often used in garages, utility rooms, and between living spaces and attached garages for added safety.

Soundproof Drywall (Acoustic Drywall)

Acoustic drywall is engineered to absorb sound and reduce noise transmission between rooms. It is often used in bedrooms, home theaters, offices, and music rooms.

VOC-Absorbing Drywall

This specialty drywall captures and neutralizes volatile organic compounds (VOCs) from the air, boosting indoor air quality.

Ceiling Drywall

Ceiling drywall is designed to be lighter and more rigid, helping to prevent sagging when installed overhead.

Flexible Drywall

This thin drywall (usually 1/4-inch thick) can be bent to create curved walls, arches, and other architectural features.

Sheetrock sheets are available in most types, offering the same specialized features for different applications.

Are Ceilings Made of Drywall?

Yes, most modern ceilings are made of drywall. Ceiling drywall is typically lighter and sometimes thicker than wall drywall to prevent sagging and ensure a smooth, even finish. When installing drywall on ceilings, it’s essential to use the correct thickness and type for the best results. Professional installers know how to properly secure ceiling drywall to prevent cracks, drooping, or other issues over time.

Choosing The Right Drywall For Your Project

The best drywall for your project depends on your individual needs and the environment where it will be installed. Here are a few tips from our professional experience:

• For standard living spaces, standard drywall or Sheetrock is usually sufficient.

• Moisture-resistant or mold-resistant drywall is a smart choice in bathrooms, kitchens, or laundry rooms.

• Use fire-resistant drywall for garages or areas where fire safety is a concern.

• Consider soundproof drywall in bedrooms, offices, or entertainment spaces for added comfort and privacy.

• For ceilings, use ceiling-rated drywall to prevent sagging.

Always consult a professional contractor or drywall installer to ensure you choose the right type and thickness for your home or business.

Why Professional Installation Matters

While drywall may seem straightforward, proper installation is key to a flawless finish.

Professional installers know how to handle large, heavy sheets, make precise cuts, and ensure all seams and joints are properly taped and finished. This expertise prevents common issues like cracks, uneven surfaces, or visible seams.

A professional will also help you select the best drywall material, considering moisture, sound, fire safety, and aesthetics. Whether building new walls, repairing damage, or renovating your space, expert installation ensures your investment looks great and lasts for years.

Final Thoughts

The difference between drywall and Sheetrock comes down to branding and reputation, but both serve the same essential function in modern construction. With various types available, drywall is a versatile and cost-effective material for creating beautiful, durable walls and ceilings. If you’re planning a renovation or new build, consult a professional to choose the right drywall for your needs and ensure a smooth, long-lasting result.
