Sheathing
Overview
The structural covering placed directly over framing members which also serves to transfer loads into an I-joist. Wood structural panel sheathing is commonly sold and installed in 4’ x 8’ sheets.
OSB Sheathing
Oriented Strand Board—Manufactured from waterproof heat-cured adhesives and rectangularly shaped wood strands that are arranged in cross-oriented layers, similar to plywood. This results in a structural engineered wood panel that shares many of the strength and performance characteristics of plywood. Produced in huge, continuous mats, OSB is a solid panel product of consistent quality with no laps, gaps, or voids.
Wood structural panel sheathing thickness is determined based on the spacing of the floor joists.
Wood structural panel floor sheathing spans across multiple floor framing members for extra strength and stiffness.
OSB or plywood sheathing is attached to the floor framing with the long edge of the panel perpendicular to the span of the framing member.
Plywood Sheathing
Plywood—Manufactured from thin sheets of cross-laminated veneer and bonded under heat and pressure with strong adhesives. Plywood is also referred to as a wood structural panel.
