In the world of construction and interior design, choosing the right drywall can make all the difference. Type C and Type X drywall are two popular options, each with its own unique properties and applications. In this guide, we'll explore the key differences between the two types of drywall, and help you determine which one best suits your project.

Type C vs Type X Drywall: Key Differences

Type C and Type X drywall are distinct varieties of drywall used in construction. The primary difference lies in their fire resistance. Type C offers improved fire protection with a higher resistance rating, making it suitable for areas requiring enhanced safety, like commercial kitchens or stairwells. In contrast, Type X is less fire-resistant but is still effective in residential applications. Type C's increased thickness and additives make it heavier, requiring proper support. Type X, while lighter, necessitates fire-resistant joint compounds and proper installation for optimum results. The one you use will depend on your project's specific fire safety needs and local building codes.

Pros of Type C Drywall

Of course, you also want to take any disadvantages of this drywall into consideration: 

  • Heavier and thicker: Type C drywall is thicker and heavier than standard drywall, which may require additional structural support during installation.

  • Cost: It tends to be more expensive than regular drywall due to the added fire-resistant properties.

ProsCons

Pros of Type X Drywall

The advantages of Type X drywall include:

  • Versatility: It can be used in various interior wall and ceiling applications, making it a versatile choice for builders and homeowners.

  • Cost-effective: Type X drywall installation is typically less expensive than Type C and other specialty drywall types, making it budget-friendly.

Cons of Type X Drywall

Some disadvantages of Type X drywall you will want to consider are:

  • Limited fire protection: While it offers fire resistance, it may not provide as high of a level of protection as Type C drywall, so it's not ideal for high-risk areas.

  • Installation requirements: To maintain its fire-resistant properties, Type X drywall requires proper installation and the use of fire-resistant joint compounds and tape.

When deciding between Type X vs Type C drywall for your project, think about what your priorities are and which material stands out in that category. Remember—if you’re ever unsure of which type of drywall is the right fit for your home–you can talk with a professional drywall installer to help you decide.

Durability​​: Type C

Type C drywall holds the upper hand in durability, primarily due to its thicker build and enhanced fire-resistant properties. It is better suited for high-traffic areas and environments where extra protection against wear and tear is necessary.

Price​: Type X

Type X drywall is the more budget-friendly option. On average, it may cost between $1.00 to $3.00 per square foot, including materials and installation, while Type C drywall ranges between $1.50 to $3.50 per square foot, including materials and installation–primarily due to its . fire-resistant properties. 

Length of Life​: Type C

Type C drywall offers a longer lifespan due to its enhanced fire resistance and durability. It is better equipped to withstand the test of time, making it the winner in this aspect. Working with the right drywall contractor can also extend the life of your drywall.

Fire Resistance: Type C

Type C drywall is specifically designed for high fire resistance. It contains additives that enhance its fire-resistant properties, and it is thicker and denser than regular drywall. Type C drywall typically has a 1-hour fire rating and can withstand fire exposure for a longer duration compared to Type X drywall. Type X drywall also provides some level of fire resistance but is not as fire-resistant as Type C. It is designed to offer a 30-minute fire rating, making it suitable for residential applications and areas where a moderate level of fire protection is sufficient.
