What are the three common types of sheathing the nominal sizes and the advantages of each?

The three common types of sheathing are plywood, oriented strand board (OSB), and particleboard. Plywood typically comes in nominal sizes of 4x8 feet and is known for its strength and durability, making it ideal for structural applications. OSB, also in 4x8 feet sheets, offers a cost-effective and moisture-resistant alternative, making it popular for walls and roofs. Particleboard, usually available in similar dimensions, is lighter and more affordable, though it is less moisture-resistant and suitable primarily for interior applications.
