Structural Plywood

Definition

Structural plywood is the highest grade of plywood, often of exterior structural grade, secured to the topside of floor joists to create rigidity in the building superstructure and provide a smooth, even surface to receive finish floor covering.

Purpose

The purpose of structural plywood is to provide a strong, stable base for floors, walls, and roofs, enhancing the structural integrity and rigidity of buildings.

Examples of Use

• Residential flooring systems use structural plywood as a subfloor to support finish flooring materials.
• Roof sheathing in houses and commercial buildings employs structural plywood for strength and stability.
• Wall panels in prefabricated buildings are often made from structural plywood for quick and durable construction.

Related Terms

• Plywood: A panel made from thin layers of wood veneer glued together.
• Subfloor: The structural layer beneath the finish floor, providing support and stability.
• Sheathing: The layer of boards or panels that forms the surface onto which roofing or siding is applied.

Notes

Structural plywood is engineered to meet specific strength and durability standards, ensuring it can withstand the demands of construction and long-term use.
