What thickness is Type X gypsum typically associated with?

Type X gypsum board is specifically designed for use in fire-rated assemblies, providing enhanced fire resistance compared to standard gypsum board. It is typically 5/8 inch thick, which not only helps improve its fire-resistive properties but also allows it to meet the necessary building code requirements for various structures, particularly in residential construction. The thickness is integral to the board's performance; when installed properly, it can help limit the spread of fire and contribute to the safety of the occupants within the building.

In contrast, other thicknesses such as 1/2 inch, 1 inch, or 3/4 inch do not align with the established standards for Type X gypsum, which is why they are not the correct choice in this context. 5/8 inch thickness has become the standard for fire-rated applications, ensuring compliance with local building codes and safety practices.
