Manufactured from waterproof heat cured adhesives and rectangularly shaped wood strands that are arranged in cross oriented layers osb is an engineered wood panel that shares many of the strength and performance characteristics of plywood.
Osb shear wall panel.
Wood structural panels wsp provided an average ultimate lateral resistance capacity of 351 pounds per lineal foot plf with no interior gypsum wallboard gwb applied.
If the inside finished ceiling height will be 8 feet you can hang 9 foot osb panels vertically on the exterior walls.
The strands are glued together under heat and pressure to make.
This table lists the shear panel thickness usually listed as 15 32 inch cdx plywood or 7 16 inch apa rated sheathing osb.
A cost effective high performance structural panel lp osb is designed for optimal performance and stability.
Oriented strand board pros.
When osb panels are created thin wood strands are combined with adhesive and then hot pressed into sheets.
It s made up of hundreds of thin wood strands that have been pressed into a board with resin and wax adhesives.
Osb s strength comes from the fact that strands of wood are aligned in each layer and that each layer is perpendicular to the one below they mimic plywood in this perpendicular layering.

It contains only low emitting safe resins and is offered in a comprehensive range of performance categories.
The schedule also calls out the attachment of sheathing to framing as well as the attachment of the wall to the foundation and roof.
Oriented strand board osb is an engineered wood structural panel created of strands of wood about 1 inch wide and up to 4 feet long.
