What is Drywall? Where is Drywall Used?

Drywall, also known as gypsum board or plasterboard, is a widely used construction material that plays a vital role in creating interior walls and ceilings. It offers a smooth and durable surface, making it a popular choice for residential and commercial buildings alike.

In this article, prepared by Ayba Metal, the prefabricated building and drywall profile brand; we will explore what drywall is, what it is made of, and its various applications. So, let's dive in and discover the world of drywall!

What is Drywall?

Drywall is a panel made from gypsum plaster, sandwiched between two layers of paper. It is available in large sheets and is commonly used to construct interior walls and ceilings. The term "drywall" is derived from the fact that gypsum plaster, the primary component, is mixed with water to create a paste. When the paste dries, it hardens to form a solid and robust surface.

What is Drywall Made Of?

Drywall consists of gypsum, a naturally occurring mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). Gypsum is a soft and abundant mineral found in various parts of the world. To manufacture drywall, the gypsum is first mined, then crushed into a fine powder. 

This powder is then mixed with water to form a thick paste, which is spread onto a layer of paper. Another layer of paper is placed on top, and the entire assembly is compressed and dried to create the final drywall sheet.

What are the Types of Drywall?

Drywall comes in several types, each with its unique properties and applications. Let's explore the most commonly used types of drywall:

Regular Drywall 

Also known as standard drywall, this is the most basic type. It is typically white in color and used for general purposes in non-specialized areas of a building.

Moisture-Resistant Drywall

As the name suggests, moisture-resistant drywall is designed to withstand moisture and humidity. It is commonly used in areas prone to dampness, such as bathrooms, kitchens, and basements.

Fire-Resistant Drywall

Fire-resistant drywall, also called Type X drywall, has additives that enhance its fire resistance properties. It helps slow down the spread of flames during a fire, providing valuable time for occupants to evacuate the building safely.

Soundproof Drywall 

Soundproof drywall, also known as acoustic drywall, has sound-dampening properties. It is commonly used in theaters, music studios, or any space where noise reduction is a priority.

Mold-Resistant Drywall 

Mold-resistant drywall is specially formulated to inhibit the growth of mold and mildew. It is typically used in areas that are susceptible to moisture, such as bathrooms, laundry rooms, and basements.

Applications of Drywall

Drywall is an incredibly versatile material and finds extensive use in both residential and commercial construction. Here are some of the primary applications of drywall:

Interior Walls 

Drywall is widely used to create interior walls in homes, apartments, offices, and commercial buildings. It provides a smooth surface that can be easily painted or textured, offering a clean and finished appearance.


Drywall is commonly used to construct ceilings due to its lightweight nature. It provides a sturdy surface and can accommodate various designs, such as recessed lighting or decorative finishes.


Drywall is often utilized to create partitions within a building, allowing for the division of large spaces into smaller rooms. These partitions can be easily modified or removed as needed, making drywall a flexible choice.


As mentioned earlier, soundproof drywall is an effective solution for reducing noise transmission. It is commonly used in spaces where sound insulation is crucial, such as recording studios, home theaters, and conference rooms.


Drywall is often used in renovation projects to update existing spaces or convert open areas into separate rooms. It allows for easy modifications and can be installed quickly, making it an ideal choice for remodeling projects.

What are the Benefits of Drywall?

Drywall is a cost-effective option compared to traditional plaster walls. The manufacturing process and materials used in drywall production make it a more affordable choice for construction projects, helping to reduce overall expenses.

Easy Installation 

One of the significant advantages of drywall is its ease of installation. The large, lightweight sheets can be quickly and efficiently installed, saving time and labor costs. Drywall installation requires minimal specialized skills, making it a suitable option for both professionals and DIY enthusiasts.


Drywall offers versatility in design and customization. It can be easily cut, shaped, and textured to fit various architectural styles and preferences. Whether you desire a smooth finish or a textured surface, drywall can be tailored to meet your specific aesthetic requirements.

Smooth and Even Surface

Drywall provides a smooth, seamless surface that is ideal for painting, wallpapering, or applying decorative finishes. Unlike traditional plaster walls, drywall does not require extensive preparation or sanding to achieve a flawless finish.

Fire Resistance

Fire-resistant drywall, such as Type X, offers enhanced fire protection. It contains special additives that slow down the spread of flames, giving occupants valuable time to evacuate and providing firefighters with a better chance of controlling the fire.

Sound Insulation

Drywall has excellent soundproofing properties, making it an excellent choice for reducing noise transmission between rooms. Soundproof drywall is specially designed with additional layers and materials that absorb and dampen sound waves, creating a quieter and more comfortable living or working environment.


Drywall is a durable and long-lasting material. It can withstand normal wear and tear, providing a solid and sturdy surface for years to come. With proper maintenance, drywall can maintain its integrity and aesthetics over an extended period.

Energy Efficiency 

Drywall contributes to energy efficiency in buildings. It can be paired with insulation materials to improve thermal performance, reducing heating and cooling costs. By creating a more insulated environment, drywall helps maintain comfortable temperatures and minimizes energy wastage.

Mold and Moisture Resistance 

Moisture-resistant and mold-resistant drywall are designed to withstand high humidity levels and prevent the growth of mold and mildew. These types of drywall are commonly used in areas prone to moisture, such as bathrooms, kitchens, and basements, providing peace of mind and helping to maintain a healthy indoor environment.

Ease of Repair

In the event of damage, drywall repairs are relatively straightforward. Small holes, cracks, or dents can be patched and smoothed out quickly. Unlike plaster walls, which often require extensive repair work, drywall repairs are typically more convenient and cost-effective.
