Recent Posts. November October September August There are no weak spots that can be found in plywood when knotholes in plies overlap each other.
Each finished panel has properties similar to plywood, but is structurally more uniform and costs less. OSB has a greater load-bearing capacity than milled wood panels and that is why it replaces plywood in many sectors, especially in the North American structural panel market. Green builders appreciate that OSB is made from small, fast growing trees, many of which come from tree farms rather than forests. It can also be fabricated in 9-foot sheets, which means a wall can be sheathed from the top plate to the bottom of the floor joists with single, vertical sheets.
While plywood is generally limited to 8 to 10 feet lengths, OSB panels can be manufactured in lengths up to 16 feet. However, there is one area of concern in which plywood beats OSB. The biggest difference is how both react when exposed to large amounts of moisture over an extended period of time. Except on projects in very dry regions, i. Southwest United States , sheathing is often exposed to rain, snow, and ice during construction delays.
When plywood gets wet, it tends to swell. However, it does so consistently across the sheet, and returns to normal dimensions as it dries out. Because Plywood dries out relatively quickly, the swelling is usually not enough to affect roof finishes. In this case, plywood has the edge. It has better structural integrity than plywood, it's less expensive, and contemporary products are just as able to repel rain and moisture.
In order to obtain the thin sheets of laminate to make plywood, manufacturers have to slice them from full logs, but they grind logs into strands in order to produce OSB.
They orient the strands in piles, and arrange these perpendicular to each other to mimic plywood. This gives OSB more shear strength than plywood, and it has virtually no tendency to delaminate. By saturating the strands with wax before gluing them together, manufacturers give OSB an ability to repel water that is equal to or better than that of plywood.
Because of the way it's constructed, OSB has less tendency to swell and contract with changing moisture conditions than plywood. It also has less tendency to absorb moisture, but once moisture penetrates, it doesn't evaporate as easily. Moisture causes the edges to swell more than the centers, and this can produce noticeable ridges under thin roof coverings such as asphalt tiles.
