OSB Sheathing
Structural OSB sheathing supplied through Dynamic Lumber Solutions lumberyard locations for wall, roof, and subfloor construction.
OSB Sheathing Supplied Through Our Lumberyards
Dynamic Lumber Solutions supplies OSB sheathing as part of complete framing material packages and stocked inventory through our lumberyard operations. Builders typically source OSB alongside framing lumber, engineered floor systems, and structural beams as part of coordinated material lists.
What Is OSB Sheathing?
Oriented Strand Board (OSB) is an engineered wood panel manufactured from rectangular wood strands arranged in cross-oriented layers and bonded with structural resins under heat and pressure. This process produces panels with consistent strength, uniform thickness, and predictable structural performance.
Common Uses of OSB Sheathing
- Exterior wall sheathing
- Roof sheathing for trusses and rafters
- Subfloor and floor deck systems
- Garages, additions, and accessory structures
OSB Panel Types & Thicknesses
OSB panels are produced in a range of thicknesses and configurations to meet structural requirements. Common options include square-edge panels for wall and roof applications and tongue-and-groove (T&G) panels designed for floor systems where edge support is required.
Structural Ratings & Code Considerations
Structural OSB panels are manufactured with APA performance ratings, span classifications, and exposure designations that define approved applications within wall, roof, and floor assemblies. Panel selection should always follow current building codes, manufacturer span tables, and engineered plans.
OSB vs. Plywood
OSB and plywood are both approved structural sheathing products under modern building codes and are often considered structurally equivalent when matched by thickness and span rating.
OSB is commonly selected as a more cost-effective alternative to plywood due to its uniform strength, consistent thickness, and wide availability. Plywood may still be specified for certain applications based on project requirements or local practices.
