What is the thickness of the drywall component in the exterior wall?

The thickness of drywall used in standard construction practices is typically 1/2 inch for interior and exterior walls. This thickness strikes a balance between durability and weight, making it suitable for various applications. Additionally, 1/2-inch drywall is common for residential construction, offering adequate soundproofing and insulation properties.

Other thicknesses, such as 3/4 inch, are less common for standard wall applications and are typically used in specific situations, such as for acoustical or specialized fire-resistant drywall. Thinner options like 1/4 inch can be used for specific applications, such as decorative or overlay installations, where added thickness is not necessary. Similarly, the 3/8 inch thickness is generally associated with specific requirements but does not match the standard thickness found in most exterior wall assemblies.
