Structural 1 Rated CDX Plywood Sheathing – Exposure 1

Durable, reliable, and built for demanding structural performance, this APA Rated Structural 1 CDX plywood is ideal for roofing, flooring, wall sheathing, sheds, garages, and heavy-duty construction projects.

Plywood is the original engineered wood panel, made by layering thin sheets of wood veneer in a cross-laminated design for added strength and stability. During manufacturing, logs are peeled into thin veneers, dried, graded, and bonded together under heat and pressure to create strong, dependable panels. The alternating grain pattern helps improve durability, reduce warping, and increase overall structural strength.

Structural 1 Performance

Structural 1 is a premium APA designation used for plywood panels with enhanced racking strength and improved cross-panel performance. These panels are commonly used in more demanding structural applications such as:

• Structural shear walls
• Panelized roofing systems
• High-load construction projects
• Areas requiring additional strength and rigidity

Features:

• APA Rated Structural 1 plywood sheathing
• Exposure 1 rated for temporary moisture and weather exposure during construction
• Built with exterior-grade adhesives for added moisture resistance
• Cross-laminated veneer construction for improved stability and reduced warping
• Enhanced racking and cross-panel strength compared to standard sheathing
• Commonly known as “CDX” plywood in the construction industry
• Excellent for roofs, walls, subfloors, sheds, garages, and structural applications

Important Information:

This plywood is designed to withstand temporary exposure to moisture or weather during construction but is not intended for permanent outdoor exposure. For continuous long-term outdoor use, an Exterior-rated plywood panel is recommended.
