What building material is commonly used for panel sheathing in interior walls?

1. Plywood

2. OSB (Oriented Strand Board)

3. Fiberboard

4. Wood structural panels

The correct answer is: Wood structural panels

Panel sheathing in interior walls is often made from wood structural panels, which include materials like plywood and OSB (Oriented Strand Board). These materials are designed to provide structural integrity and thermal performance while being relatively lightweight and easy to install. Wood structural panels are strong and capable of bearing loads, making them ideal for use in wall assemblies. They also have good insulation properties and can help with sound absorption, enhancing the overall comfort of the interior space. The use of wood structural panels is common due to their versatility, strength, and ability to meet building codes while providing a stable base for finishes, such as drywall. Other options listed, like plywood and OSB, fall under the category of wood structural panels but do not encompass the full range of engineered wood products available for this application. Therefore, the designation of wood structural panels captures a broader category that includes these materials and is therefore the most accurate choice for describing the typical sheathing material used in interior walls.
