The Basics

Standard Drywall Sheets

Standard drywall is the most common type of drywall. Standard drywall is ideal for walls and ceilings in rooms where moisture is not a concern. It is commonly made of a gypsum core wrapped in durable paper.


Moisture-Resistant Drywall

Moisture-resistant drywall, also known as greenboard, is designed for areas with high humidity, such as bathrooms, kitchens, and basements. It features paperless backing and a special coating to prevent molding from moisture exposure.


Fire-Resistant Drywall

Fire-resistant drywall contains special non-combustible fibers that enhance its fire-resistance properties, making it suitable for garages, utility rooms, and commercial buildings. This type of drywall prevents the spread and speed of fire.


Soundproof Drywall

Soundproof drywall, also known as sound-dampening drywall is thicker than other drywall types and is constructed of special materials to reduce sound transmission. It is perfect for bedrooms, home theaters, and offices.


Eco-Friendly Drywall

Eco-friendly drywall is similar to standard drywall except it is constructed of recycled materials.

Finishing Touches

Joint Compounds / Drywall Mud

Joint compounds, often referred to as “drywall mud,” are materials used in the finishing process of drywall installation. These compounds are applied over the seams between drywall sheets, as well as over screw or nail holes, to create a smooth, seamless surface ready for painting or wallpapering.

Drywall is available in four thicknesses to cater to your project’s needs and purpose.

  • 1/4 -Inch: This thickness is the most commonly used to be mounted over an existing wall to hide old damages and to refresh a space. This thickness also works great for walls that have curves, as it works to fit bends rather than thicker panels.
  • 3/8-Inch: This thickness is commonly used to repair existing drywall projects. It is also thin enough to be manipulated into fitting curved wall.
  • ½-Inch: This thickness is the most common drywall thickness for standard interior walls.
  • 5/8-Inch: This is the thickest drywall available and is often the thickness of fire-resistant and soundproof drywall.
