OSB vs. Plywood

Here are the results of shooting a 2" x 4" at both materials.
After just witnessing a hurricane dance through our neighborhood a few months ago I can attest that people in panic mode will buy anything left in stores to put over their windows in hopes of stopping at least some of the punch. People in big box stores buying 3/4" or 1/4" birch plywood since it was all that was left and I even saw a few folks using sheetrock to make storm shutters. In the heat of the moment, you do what you feel you have to do I guess - try and protect your family.

I don't doubt the plywood will stop 2x4 better than OSB, but did you notice they used 5/8" plywood vs 1/2" osb.
I don't think 5/8" osb would have a different result, but you would think they would have at least tested apples vs. apples.

Agreed,but you have to test some way. The point they are showing is the inferiority of OSB,which is pretty much the material used the most for walls,floors and roof sheating. Why ? Because it is cheap.
I certainly hear what your saying,however,if you live in an area prone to hurricanes,would it not be prudent to have material cut to size and numbered for each opening needing protection stored in attic,garage,crawl space or some similar location for each time there is a threat ? It seems anything short of that is irresponsible.

Oh yeah,what this video shows is the true sense of false security one adapts boarding up their windows prior to a storm. All the while thinking they are out of harms way in their house sheated with that stuff covered with plastic siding.
Again,people like it 'cause its cheap.In most instances cheap products chase out quality,because of price. Seldom is a "new" product that is cheaper better than the one it replaces. Can happen,but is a rarity.
The video did just show you a house failing. I guess you are o.k with flying debris coming thru your walls.
I'm not advocating titanium walls,how about just something like solid wood or at the least plywood. If you are not able to recognize / accept this video for what it is,so be it.
While I agree that plywood is better than osb for covering windows in a storm, I don't think that for the price, it is better than osb for home construction. The Advantech that we use for the subfloor holds up so much better than plywood in test after test, that there is no comparison.Oh yeah,what this video shows is the true sense of false security one adapts boarding up their windows prior to a storm.

As for wall sheathing, in about 99% of walls, the structural ability is more than adequate when using osb. There are a few cases when plywood may be required on some walls , but there is no reason to use it on the whole house. It will be covered by Tyvek or some other paper, so the wet factor wont come into play either.
The roof to me presents the only opportunity to make a strong case for plywood. The problem is that most of the standard cdx 4 ply that most yards now get is crap. If you upgrade to a fir plywood, or maybe get the 5/8", the quality improves, but the price increases. The cheap stuff just does not lay flat and in many cases mirrors though the roof shingles.
