Which of the following is a common use for OSB (Oriented Strand Board) in construction?

OSB, or Oriented Strand Board, is commonly used in construction due to its strength and versatility. One of its primary applications is for roof sheathing. This material provides structural support and helps create a solid base for roofing materials. Its dimensional stability and resistance to warping make it an excellent choice for this purpose, allowing it to hold up well under a variety of weather conditions. Additionally, OSB is typically more cost-effective than plywood, making it a popular choice for builders looking to maintain budgets while ensuring quality.

In contrast, external cladding is generally made from materials that provide weather resistance and aesthetics, like vinyl, wood, or fiber cement. Concrete forms are usually made from materials specifically designed to handle wet concrete, such as plywood or specialized formwork systems, which differ from OSB. Electrical wiring is unrelated to OSB's structural applications, as it involves electrical components that require proper insulation and protection, which OSB does not provide. This context highlights OSB's suitability for roof sheathing as a common construction use.
