What thickness of drywall should you use on interiour walls of commercial building?

For interior walls of commercial buildings, 5/8-inch thick drywall is commonly used due to its fire-resistance properties and durability. This thickness is suitable for most applications and meets building code requirements for commercial spaces. In some cases, 1/2-inch drywall may be used for non-rated partitions, but it’s essential to consider the specific needs of the project and any applicable regulations. Always consult local building codes to ensure compliance.
