What is the thickness of the sheathing in the wall?

The thickness of wall sheathing is a critical aspect in construction, as it contributes to the structural integrity and insulation properties of the wall assembly. In many construction scenarios, especially for residential applications, a thickness of 1/2 inch for wall sheathing is commonly adopted. This thickness provides a good balance between strength and weight, making it suitable for various types of wall panels and supporting materials.

Sheathing serves multiple purposes, including providing a base for exterior finishes, enhancing rigidity, and offering some level of insulation. While other thicknesses such as 3/4", 1/4", and 5/8" exist in the market and are used for specific applications or materials, 1/2 inch is frequently specified in design materials and building codes for standard wall construction. Hence, identifying 1/2 inch as the thickness of the sheathing in the wall reflects both industry standards and common practice.
