What is the best sheathing for walls?
Plywood and OSB are largely considered the best wall sheathing choices because of their overall abilities to hold fasteners well, create a strong bond between studs, and provide some thermal advantages. The “big two” aren't the only selections available however. Structural fiberboard is one such option.
What type of sheathing is used for exterior walls?
There are many exterior wall sheathing options available, with wood sheathing being one of the most commonly used materials. Wood sheathing materials include plywood, oriented strand board (OSB), and waferboard. Plywood is made of whole sheets of wood that are cross-laminated.
Should you screw or nail OSB board?
A hammer and 8d nails are standard for installing OSB, but you can speed up the installation by using a nail gun. The caveat when using a nail gun is to set the depth of the nail so the head just dimples the surface of the OSB.

To be most useful, it should also have edge nailing at other significant framing members like the bottom wall plate.
What is exterior wall sheathing?

Why use OSB instead of plywood?
Recently, oriented strand board (OSB) has been used in place of plywood due to lower production costs--in some areas of the country it's nearly half the cost of plywood. Both materials are rated equally for sheer strength by the Engineered Wood Association, but many carpenters prefer plywood over OSB for a variety of reasons.
Does plywood hold up better in moist conditions?
The edges of plywood panels better resist chipping on tighter nailing patterns, and they hold up better in moist conditions than does OSB, whose edges can swell up to 15 percent when wet. During a home renovation, the sheathing should still be usable if moisture has not been trapped behind the siding.
Can OSB be used to replace board shear?
For most home restoration projects, plywood or OSB sheathing is more than adequate to replace older board-style shear paneling. Technological advances and a push for greener methods in the construction industry have led to the inception of different types of environmentally friendly sheathing materials, but most of these materials have higher price points than standard sheathing.
Where should sheathing be on a multistory building?
For multi-story buildings the sheathing on the bottom should extend down to the bottom of the lowest framing member & extend to the halfway point on rim-joist (as shown in red). The next piece above it should be allowed a 1/8” expansion joint ending at the top plate or at the midway point of the next rim joist. For more on these connections & other best practices you may wish to check out the APAwood.org site.
Who invented wall sheathing with trusses?

How does wind damage a building?
While one would assume the most damage from the winds comes from the wind hitting the building, most damage sustained comes from the wind hitting the building at an angle where it can get behind the siding and essentially peel it off.The next biggest area of damage actually is on the backside of the building where the suction forces created can easily rip off most sidings & even foam board. (For example the assembly needs to be able to resist anywhere from a-29 PSF force at the corners, while the center area should be able to resist a -24 PSF.The bulk of damage from wind hitting a building straight on is actually caused by debris penetrating the structure which is why many coastal communities require “hurricane” glass or some other form of protection. This is also one reason why you may wish to consider bumping your sheathing up past code minimums & going with a thicker panel. At minimum I prefer a ½ sheet for 16” OC framing, while others I know will go no less than 5/8 or ¾. ¾ plywood is a favorite for some as it has been tested to stop a 2×4 being shot at it @ 120 mph.
What is sheathing used for?
If I had to sum up sheathing I would refer to it as; A material used to enclose & protect the structure (along with its contents) which also helps provides the needed structural stiffness & backing required by that assembly.

Why do you need to use a 16 penny nail between sheets?
For years, many of us simply installed sheathing horizontally & used a 16 penny nail slid between the sheets to help ensure there was room for expansion & to help reduce the swelling caused by an moisture that got between the two sheets. With changes to the codes (caused mainly by a better understanding of seismic shear forces & what was required to help prevent a wall from racking in the wind…) it became a requirement in certain areas to start sheathing the corners & a few select other areas vertically.
Can you install a zip wall vertically?
While some may like the idea of going vertical it just might not be in the works for them, but no worries there are ways of installing it where you can still gain some of the benefits. Zip Wall is an interesting system which combines the sheathing with an integrated WRB & air barrier all in one.
