If strength comparison is the goal, both the plywood and the OSB s/b the same thickness. 5/8" plywood and 5/8" OSB. Having said that, I believe there are ply variants within the category of plywood (3, 5, and 7?) and the number of plies affects the strength and I believe the cost. It would be interesting to identify the most common plywood available for the purpose and the other variants and compare their strength. Bottomline is this test needs more breadth of product. IMO
Plus use osb vs plywood for subfloor , People use osb on roofs as well... Plywood gets wet, it may buckle, or one top layer raise up, but often when it dries out , it will go back down, at least partly, osb gets wet, it swell up like a sponge, separating all the strands that had been held together by adhesives, them when it dries out, it often flakes apart, I've seen it almost disintegrated like sawdust. I use it occasionally, just because of the huge cost difference, but when quality counts, and budget allows- I always choose plywood.
Mitchell Buss buy the right grade of plywood. CDX can get very wet for a reasonable period of time (you can sheet a floor and miss work for a few days because of rain and it will be fine)
Did you watch the entire video? The test was to show the difference between doing it right and people cheapening out to save a few bucks. It wasn't intended to be fair. It was intended to show which is better for protecting your windows, spending more money and buying a superior product or being a cheapskate. Even if they had been the same thickness, the result would be the same. OSB is shit.
@@HTHAMMACK1 OSB and plywood are actually pretty close you need to read up on the scientific literature. Also there are numerous types of OSB. OSB is actually denser than plywood and more consistent so if anything the same thickness of OSB is likely to resist that 2 x 4. On the other hand plywood is slightly stiffer then OSB. Depending on which OSB sheet you get, will determine on its ability to withstand water and Vapor
@@blaisefrancis7523 that is true in some situations. However look up the structural Integrity values for OSB vs. Plywood in subfloors. You will see after doing a couple days of research as I did that these strand subfloors are infinitely better than plywood counterparts. That's why OSB has completely taken over the market and there is only one or two products out there that are doing plywood and no one's buying them. When it comes to wall sheathing, plywood all the way. But no one's putting plywood subfloors in their Mansions anymore. The OSB is the better product regardless of money. I know this because I wanted the ultimate fast regardless of price. And everyone is using either advantech for Edge gold in 1in 1/8 in for the best subfloors. Now if you're doing hardwood floors on top of that they will go again over that with non-structural OSB or plywood. And that is mainly just to even out seams.
@@blaisefrancis7523 I used to think exactly like you did. In fact I was almost ready to send back to the factory $5,000 of subflooring and change it out for plywood. Then I started looking around and there's only one or two products who make 1in 1/8 plywood. I think one of them is called sureply. So I started calling and talking to manufacturers and after doing a painful amount of research I decided not to send back my OSB Edge gold. It used to be the case that plywood was better but the advances in OSB have destroyed that myth, at least as far as subfloors go. You can hold on to that tradition that plywood is better but you'll never convince me. Do some research here on RUclips and you'll see why OSB has completely taken over the market on subfloors, and it's not for cost. Like I said Money Was No Object on my subfloors and I decided not to use ply after I researched it. Some of the problems with plywood is that it's very hard to find in 1 1/8 thickness, it often has voids and is dimensionally inaccurate. It's not as dense which is what you want for subfloors. The modern OSB products also are more resistant to water then plywood. They now come with several hundred day exposures before sanding is needed. You will be very hard-pressed to find any high end contractor using plywood as subfloors. And I am a guy who loves Plywood And I sheeted my entire building with 3/4 inch plywood. But when it comes to subfloors OSB has the advantage hands down. And when we say OSB that's kind of a misnomer because these products are not referred to as OSB they are a strand product but they are very different than the OSB you would go pick up from Home Depot or Lowe's. It's a completely different animal. I don't know if you're a builder or a homeowner but do a little research and you might find out that your opinion changes like mine did.
The comparison should be for the same thickness of material, otherwise some strength is associated to that parameter, or compare the same price elements and analyze damage
Plywood has the strength of full wood fibers glued 90 degrees from previous layers, so equal thickness to equal thickness, is probably stronger than what was developed to utilize waste material and market it as a "building product" (OSB). That said, the test isn't equal size to equal size. It's skewed toward favoring the plywood. Added to that, nominal 1/2" OSB is 7/16" thick. Why not go to 3/4" OSB, which is also readily available, yet obviously more expensive than cheap roof decking? Or at least use 1/2" CDX sheathing grade ply to be at least similar to the OSB. Since the video favors one material over another while touting one's strength qualities over the other, why not compare "Hardwood" plywood? How about comparing 1/4" birch, lauan, or oak to 5/8 or even 1/2 ply (or even 7/16 OSB). It's hardwood after all, and some might ignore the thickness as the 2x4 blasts through (yeah, the alleged comparison is about going about a job on the cheap, but what point is more valid?). Sorry for going on so long, but as others commented here, it's not a fair test at all.
5/8" Plywood Vs 1/2" OSB not that much difference in thickness but for the same shear strength you would need 1" 1/4 OSB to equal a 5/8 Plywood.. that is the difference and OSB is an awful product when water is applied to it. I'll never buy OSB.
@@x_III_III_III_x OSB is superior to plywood in shear for the same thickness. But in this test and many others, plywood is superior to OSB for impact resistance for a similar thickness. This is a straight up impact test.
I get the purpose of the test using the 7/16 osb. I would really like to see how 5/8 Advantech would hold up to the 2x4. Not that it is any cheaper then cdx but would be a neat comparison of strength
Hmmm, let's compare 5/8 to 1/2 inch and see which one is stronger. How about doing a test to see how thick OSB needs to be to give the same protection as plywood (whether it turns out to be 5/8 = 5/8 or not) then a homeowner can go to the store, look at two products that will provide the same protection for their home and buy the one that costs them less. That would be a useful experiment.
I never board up. Never had a window break, but I’ve had big insurance claims four times. Always ended up with money to spare. Just buy good insurance and get out of town early.
This is the same reason Skateboards are not made from OSB... Even though it would be easy and cheaper. They are made from Plywood construction....plywood is way more resilient under flexing pressure and stronger by far in all directions of stress... and it holds its integrity when exposed to water... Like the rain in a storm. It's unfortunate they didn't use the same exact thickness pieces... But this was a qualitative demonstration... Not a quantitative test... It is still an accurate representation of the difference between the two materials IMOP. PS... GOOGLE pics of 2x4s thrown by tornadoes and hurricanes...
This is why I asked my roofer to use plywood instead of osb, and paid an extra $700 for it. Do your research, use quality materials, don’t go with cheap n’ weak osb for your roof sheathing.
I'm looking for a type of wood for a subfloor that can withstand large amounts of water from underneath to uptop. What would you advise me to look for, make ect? Thx much for your expertise.
How does an inch of OSB compare to a half inch of plywood or some other combination of them or maybe OSB with paneling compared to plywood? There is a really big difference in price.
If 2x4s are flying around like that you will need a lot more than 5/8” plywood to save your house. The OSB will serve you fine to protect from smaller debri
MewCat100 you said they are comparing building code minimums. But they are comparing “1/2” osb which in most jurisdiction is 1/2 nominal which is sold as either 15/32 or 7/16 to 5/8 ply. So in your jurisdiction 5/8 ply minimum? As is 1/2 or 15/16 or 7/16 osb? In what jurisdiction would that happen? Compare 5/8 to 5/8 nothing else
MewCat100 soooo i ask again. Is code in your area 5/8 plywood or (7/16 or 15/32 or 1/2 osb) In my city code is the same for osb and ply 1/2 is minimum In my state the code is more lenient but still about the same for osb and ply
Wait, you just stated the building code states the covering "must be 5/8" thick" and then proceeded to use 1/2" thick OSB/particle board. Someone needs to learn fractions.
@@dukeigthorne5460 Probably not, actually. The tensile strength of OSB is junk. Similarly, it's with-grain compressive strength is also inferior to plywood by a mile. Both of these are necessary to resist bending. Plywood also has superior energy-absorption due to the size of the pieces of wood.
Very odd test. Most panel products are scant, 1/2" plywood is actually 15/32" and OSB is 7/16", 3/4" is really 23/32", not sure who wrote this test but they need to be more accurate.
osb or plywood for chicken coop flooring? i plan to have a large area which am hoping to support my weight for cleaning. i am gonna use osb for the walls and roof obviously with lts of protection from rain on top but was wondering if i should use plywood or thick osb? which would be a cheaper option and which would be stronger?
I doubt that the surface area of an end of a 2x is sufficient to impart much, if any propellant energy during a strong wind, it takes a purpose- designed cannon to do that. If any movement at all happens to the errant stud, it would be a tumbling, twisting path, likely “walking” along the ground rather than going totally airborne for any appreciable distance.
Even a 150mph wind gust cannot pick a 2x4 off the ground...there is not enough surface area. There needs to be a sucking force that lifts it up... AKA-strong tornado. The tornados you get in hurricane feeder bands are small spin-ups, usually F1 or less. It's an unrealistic test.
BeachsideHank Dude I've seen with my own eyes a freaking cattail stalk pierced thru a 2x4 from a tornado. Come on down to Texas we got Hurricanes and Tornados, it's a blast!
thechosendude Learn the English language please, nowhere in my comment do I state or even reference anything to do with plywood. my comment was in reply to the original post referencing mass and size. Have you suffered a recent head trauma, you may need to see a MD.
Ha, $10 for one sheet of 1/2" OSB!! Right now (April 2022), it's somewhere between $48 to $52 a sheet at H**e D***t and local lumber yards in the US East Coast. Sounds surreal.
This only tells half the story though. the plywood can easily get sucked off the building from rapid wind pressurization and depressurization cycles without proper anchorage and deteriorate significantly when wet for periods of time. It's also not the same reusing it year after year. We recommend an agency approved large missile impact protection system or a large missile resistant glazing system.
Tommy & Liberty Cabins are now two names for me to avoid because they see nothing wrong with misinformation. Your point & reputations would have soared had you compared like for like. So, because you didn't, I am drawn to conclude that 5/8 OSB would have protected the window. 19/32 OSB cost $25 & is 1/32 thinner (.030"), is readily available, & would have been a fair test. So the question just sits there. Why not an honest test?
Plywood may stop a piece of 2/4 but will not stop a tree, from coming threw your window. And people, wonder why plywood cost so much. Here is your answer.
no need for fancy cannon, you can hit through OSB simply with hammer. I always was skeptical about putting it on the floor, can't some heavy furniture make holes in it?
It especially has expansion issues. What commonly happens is the expansion will make pieces that are up against each other start creating a ridge. Then, you have to take up the floor, sand it down, and put the floor back in.
There is no building code that requires you to board up during a storm. The two products compared were of different thickness. Calling an OSB user “cheapskate” is how Floridians refer to plywood users. OSB and plywood are not that much different in the way they’re manufactured.
*Fun fact*: Most homes in hurricane areas (Florida and Gulf Coast states) are built with OSB for side and roof sheathing... Vinyl siding or hardieboard siding won't add any strength. What you see here could theoretically happen to the actual walls in the same test... In real life, pretty much never...
thechosendude so don't let anyone fire tubafurs at your house with a cannon. You don't see tubafurs going into the sides of houses like that during hurricans, do you?
KC9UDX - I'm trying my best not to let that happen. When I see the Union Army setting up their cannon, I'll be sure to grab my musket and show them who's boss.
OSB blows apart when you shake a skill saw at it. You got to try it with the steel stud. Iron American Dream on RUclips Share it. Take a ride across the promised land. Ride a Harley.
I'm planning on building a safe room with the master bdrm closet from scratch and anchored in the ground with steel trailer tie downs. I considered 1.125 t/g but the cost is crazy now.
For those complaining about the thickness, what he’s instead comparing is what happens when you try to cheap out on protecting your home during a hurricane.
The test is somewhat unfair. 3/4” OSB is still cheaper than 5/8” ply and I think in the real world it would hold up. A full length of 4/2 hitting the shutter dead square like that would be a very unlikely event.
A 2x4 or tree branch getting pushed by the wind will not fly end first. It will fly sideways. Sideways is the only way it will catch enough wind to make it move
1/2" OSB is $15.xx for a sheet here. 1/2" ply is around $18.xx sheet by comparison. Finding a flat piece of plywood here is incredibly difficult, though...every piece is warped to hell and back. The Georgia-Pacific plants near me suck....shittiest wood quality I've ever seen.
Unfortunately a few inaccuracies... The building code calls for 7/16 OSB not 5/8" plywood. Hurricane protection is not protecting the glass. All hurricane protection products are actually designed to prevent rapid internal pressurization, which is a rapid influx of air pressure inside a structure which will overload the roof. If the roof is overloaded and disengages, the walls have little if any support left and the structure is in danger of collapsing. I would have thought these guys would have more fact or at least reach out to some experts. The second issue is either plywood or PSB comes in a 4 x 8 sheet. Very few homes can be completely covered by a single sheet and you CANNOT stitch them together. For openings larger than what can be covered by a single sheet, you need to build a sub frame for either one and have now surpassed the low end of the engineered and tested Hurricane Shutters which are useable year after year.... Make good choices!
Also one more thing if you don't believe me go to any video on RUclips in time it it takes anywhere from 10 to 15 minutes for a structure that's made out this cheap wood go up like a Tinderbox they've got RUclips videos with Apartments catching on fire you see the hole apartment building go up
5/8" Plywood Vs 1/2" OSB not that much difference in thickness but for the same shear strength you would need 1" 1/4 OSB to equal a 5/8 Plywood.. that is the difference and OSB is an awful product when water is applied to it. I'll never buy OSB. Google: "What is better OSB or plywood?"
first off, plywood is not "stronger" than osb, osb actually has 2 times the sheer strength of plywood, part of the reason its used in engeneered beams. all this test proves is that a (1/5" thinner) sheet of osb is less puncture resistant than plywood, which is of little importance in the vast majority of applications. are they trying to sell plywood or something?
The extra 1/8" wouldn't matter. OSB is chipped and it would still punch out a hole. The test is flawed though, because I don't believe any piece of lumber has flown perfectly lengthways during a hurricane into a home window in over 20 years. You're statistically more likely to die via car crash, lightning strike, airplane crash, cancer, etc, than a 2x4 flying through your window. It's fear mongering at best.
shonuffisthemaster if that’s the case, you feel a PSL is stronger than an LVL. That’s the same comparison in beams as this test is to plywood. You are 100% wrong. PS is not stronger than LV nor is OSB stronger than plywood.
Tom Foolery there are pros and cons to both depending on what your doing. but ive heard the sheer strength figures repeated from several reliable sources, and the ratings for span strength seem to be about the same. osb dosent do good with water, so neglected roofing for example is a place where it fails allot. however its much flatter than plywood especially in the thinner varieties. i dont think ive ever seen an unwarped 1/2" plywood sheet but for osb its the norm. given the proce difference and negligable if any proformance difference, i usually choose osb.
Psl have different design criteria. To compare is ludicrous. The psl we used this week had modulas elastcity rating of 1.6 the lvl had 2.0 so if they had engineered the psl to a higher density it would be stronger the weaker strength is to be cost efficient rather than design a weaker member. Different products for different apps. Plywood doesn't stand up to the weather as well as Osb. It's not just because it's cheaper it has less problems. Less call back or repairs. Been framing for 35 years and have had to repair a lot of plywood.
shonuffisthemaster Trying to sell a reality check, Plywood is better than osb in almost every if not all applications, The only thing good about osb is the price , It's cheaper because in the manufacturing process there's very little waste, and it can use every square inch of the tree , as well as pieces, limbs of the tree that would otherwise be basically unusable in a plywood manufacturing plant. Here's a simple test, nail down a piece of plywood, & nail down a piece of osb, then go back and try to pull up the plywood & the osb, whatever method you choose, with care , you can remove the plywood, remove the nails, with minimal damage, possibly using the plywood elsewhere, the osb will likely be a different story, the nails will often be holding much stronger than the strength of the osb itself, meaning the osb will break, with the Nails pulling through the osb only holding a 1-2" ring around the nail, no matter how careful you are, the osb will most likely be trashed and completely unusable once you manage to get it up & clean up all the chucks that broke off. They are not even in the same quality league. And I am in the building & manufacturing arena. Selling & servicing all the various industries touched on above.
Hell with plywood...where do I get that cannon!
bcubed72. I was thinking the same thing
at canonz r us... duh...
I can shoot a potato just not lumber
If strength comparison is the goal, both the plywood and the OSB s/b the same thickness. 5/8" plywood and 5/8" OSB. Having said that, I believe there are ply variants within the category of plywood (3, 5, and 7?) and the number of plies affects the strength and I believe the cost. It would be interesting to identify the most common plywood available for the purpose and the other variants and compare their strength. Bottomline is this test needs more breadth of product. IMO
An honest comparison would be to use "same cost" boards, to see which has the best value.

osb or plywood for chicken coop flooring? i plan to have a large area which am hoping to support my weight for cleaning. i am gonna use osb for the walls and roof obviously with lts of protection from rain on top but was wondering if i should use plywood or thick osb? which would be a cheaper option and which would be stronger?
How about for a shed roof deck 20” x 30”. Not trying to spend a fortune redoing roof deck for my shed. Will 1/2” OSB be safe to walk on?
No you’ll fall right through and break all the windows installed underneath your deck
I doubt that the surface area of an end of a 2x is sufficient to impart much, if any propellant energy during a strong wind, it takes a purpose- designed cannon to do that. If any movement at all happens to the errant stud, it would be a tumbling, twisting path, likely “walking” along the ground rather than going totally airborne for any appreciable distance.
Even a 150mph wind gust cannot pick a 2x4 off the ground...there is not enough surface area. There needs to be a sucking force that lifts it up... AKA-strong tornado. The tornados you get in hurricane feeder bands are small spin-ups, usually F1 or less. It's an unrealistic test.
Might as well mandate air bags for all 2x4s. Booster seats for the shorter ones.
BeachsideHank Dude I've seen with my own eyes a freaking cattail stalk pierced thru a 2x4 from a tornado. Come on down to Texas we got Hurricanes and Tornados, it's a blast!
David Moritz - When did people start boarding up homes for tornados? A tornado is a bit different than a hurricane.
thechosendude Learn the English language please, nowhere in my comment do I state or even reference anything to do with plywood. my comment was in reply to the original post referencing mass and size. Have you suffered a recent head trauma, you may need to see a MD.
Ha, $10 for one sheet of 1/2" OSB!! Right now (April 2022), it's somewhere between $48 to $52 a sheet at H**e D***t and local lumber yards in the US East Coast. Sounds surreal.
Alright now let me trying shooting at it
This only tells half the story though. the plywood can easily get sucked off the building from rapid wind pressurization and depressurization cycles without proper anchorage and deteriorate significantly when wet for periods of time. It's also not the same reusing it year after year. We recommend an agency approved large missile impact protection system or a large missile resistant glazing system.
Tommy & Liberty Cabins are now two names for me to avoid because they see nothing wrong with misinformation. Your point & reputations would have soared had you compared like for like. So, because you didn't, I am drawn to conclude that 5/8 OSB would have protected the window. 19/32 OSB cost $25 & is 1/32 thinner (.030"), is readily available, & would have been a fair test. So the question just sits there. Why not an honest test?
you should have shown different thicknesses of osb and plywood
Put 2 OSB up and double the strength and still save money
1/2" plywood would perform the same as the 1/2' osb.
apples to oranges. In my opinion.
That was remockable!
Use transite. Problem solved. Can't get any cheaper than that, people will pay you big money to take it off their houses.
So. 5/8ths ply wood is stronger than 1/2 inch plywood aswell.
Plywood may stop a piece of 2/4 but will not stop a tree, from coming threw your window. And people, wonder why plywood cost so much. Here is your answer.
no need for fancy cannon, you can hit through OSB simply with hammer. I always was skeptical about putting it on the floor, can't some heavy furniture make holes in it?
Yes
It especially has expansion issues. What commonly happens is the expansion will make pieces that are up against each other start creating a ridge. Then, you have to take up the floor, sand it down, and put the floor back in.
There is no building code that requires you to board up during a storm.
The two products compared were of different thickness.
Calling an OSB user “cheapskate” is how Floridians refer to plywood users.
OSB and plywood are not that much different in the way they’re manufactured.
Yeah, but every part of your house other than the windows is made of OSB. So...
It would have been a better test if they were BOTH the SAME thickness. 1/2 OSB VS 5/8” plywood. Unfair test
*Fun fact*: Most homes in hurricane areas (Florida and Gulf Coast states) are built with OSB for side and roof sheathing... Vinyl siding or hardieboard siding won't add any strength. What you see here could theoretically happen to the actual walls in the same test... In real life, pretty much never...
thechosendude so don't let anyone fire tubafurs at your house with a cannon. You don't see tubafurs going into the sides of houses like that during hurricans, do you?
KC9UDX - I'm trying my best not to let that happen. When I see the Union Army setting up their cannon, I'll be sure to grab my musket and show them who's boss.
OSB blows apart when you shake a skill saw at it. You got to try it with the steel stud.
Iron American Dream on RUclips Share it. Take a ride across the promised land. Ride a Harley.
Remaaaahhkable. 1:53
Thicker plywood. Why not same size as OSB for true comparison?
Why is that guy surprised. Osb looks like it’s gonna fall apart on its own. Of course the ply is stronger
You said it yourself that plywoods 5/8 inch that OSB is 1/2 inch faulty test. Need another video
Where is the range safety officer? Both men walk in front of the "loaded" cannon with a flashing red light at 46 seconds.
In some applications plywood is stronger than OSB but it's not fair to compare 5/8 plywood versus half inch OSB
I was just researching if plywood was strong enough for a desk but nice to see what would happen if I were to use it in a hurricane.
Just be aware cheap wood can warp over time
I'm planning on building a safe room with the master bdrm closet from scratch and anchored in the ground with steel trailer tie downs. I considered 1.125 t/g but the cost is crazy now.
Why so you can be burned to death in there? Get a shotgun and a Rottweiler
@@thefix2573 Attack is the best form of defense
I’m beginning to think the 2 inch thick insulation foam boards I bought aren’t going to work…
I used to call OSB "n*****board", but since 2008 have been calling it "obamaboard".
And you are a piece of shit. Congrats for one of most ignorant comments of the year. You POS.
$10 a sheet?? I just paid $54 at Menards and that was after prices have been coming down!
YEAH, I NEED ONE OF THESE CANNONS TO MOUNT ON MY CAR WITH A GET OFF MY BUMPER TAG.
And that's why all homes nowadays are built with OSB instead of plywood great way to save guys lol
Ok cheesecake. Let's see what happens. Lol
Ffs! Test the same thickness of material
At first I thought he called him cheesecake.
For those complaining about the thickness, what he’s instead comparing is what happens when you try to cheap out on protecting your home during a hurricane.
Thats a very American comparison
Yea but I'm building a headboard for my bed...osb will be fine wrapped in faux leather
OSB good for starting fires!
Good to know Thanks
The test is somewhat unfair. 3/4” OSB is still cheaper than 5/8” ply and I think in the real world it would hold up.
A full length of 4/2 hitting the shutter dead square like that would be a very unlikely event.
Framers would have a field day with that cannon
$30 bucks a sheet. Times sure have changed.
Your grip failed setting the gopro properly.
A very good information. It may come in handy.
There's no window behind the plywood.
Osb for $10 lol in 2021
Miss the good ol days .. like 2years ago
A 2x4 or tree branch getting pushed by the wind will not fly end first. It will fly sideways. Sideways is the only way it will catch enough wind to make it move
I call it SOB board.
material bites it gets moist damp....crumbles
ADVANTECH STRUCTURAL 1 OSB
WOWWW, no wonder OSB is so cheap. Where or in what instances is OSB the best choice?
i wish it was $10 a sheet. price just went up here from 14.50 to 17.95! Just as I'm building my garage!
osb in malaysia cost about rm253 aquivalent 60usd...plywood much cheaper than osb...
$54 for a 1/2" sheet of OSB in Australia :( Not to mention $150 for a sheet of 1/2" Birch ply!)
It just hit $20.
Same price here in Argentina... but 15 mm thickness.
1/2" OSB is $15.xx for a sheet here. 1/2" ply is around $18.xx sheet by comparison. Finding a flat piece of plywood here is incredibly difficult, though...every piece is warped to hell and back. The Georgia-Pacific plants near me suck....shittiest wood quality I've ever seen.
That is high price 5/8 plywood with all those plies not a dollar for dollar comparison
What kind of a hurricane picks up a 2x4 and throws it at a window? 😃
Unfortunately a few inaccuracies... The building code calls for 7/16 OSB not 5/8" plywood. Hurricane protection is not protecting the glass. All hurricane protection products are actually designed to prevent rapid internal pressurization, which is a rapid influx of air pressure inside a structure which will overload the roof. If the roof is overloaded and disengages, the walls have little if any support left and the structure is in danger of collapsing. I would have thought these guys would have more fact or at least reach out to some experts. The second issue is either plywood or PSB comes in a 4 x 8 sheet. Very few homes can be completely covered by a single sheet and you CANNOT stitch them together. For openings larger than what can be covered by a single sheet, you need to build a sub frame for either one and have now surpassed the low end of the engineered and tested Hurricane Shutters which are useable year after year.... Make good choices!
Plywood is about 10 more bucks a sheet!!
Also one more thing if you don't believe me go to any video on RUclips in time it it takes anywhere from 10 to 15 minutes for a structure that's made out this cheap wood go up like a Tinderbox they've got RUclips videos with Apartments catching on fire you see the hole apartment building go up
5/8" Plywood Vs 1/2" OSB not that much difference in thickness but for the same shear strength you would need 1" 1/4 OSB to equal a 5/8 Plywood.. that is the difference and OSB is an awful product when water is applied to it. I'll never buy OSB. Google: "What is better OSB or plywood?"
Stone on the other hand....
Now compare Huber Woods Advantech...
5/8 plywood vs 1/2 OSB...Not fair!
$10 for osb? 7/16 is $36 now
34 mph? YES! 34 mph! Why 34mph? Because Yes!
Layer a osb behind a plywood🤔
If using osb don't shoot 4x2's at them with a cannon otherwise okay.
i have seen flake board fall apart in the weather. it is lousy .
first off, plywood is not "stronger" than osb, osb actually has 2 times the sheer strength of plywood, part of the reason its used in engeneered beams. all this test proves is that a (1/5" thinner) sheet of osb is less puncture resistant than plywood, which is of little importance in the vast majority of applications.
are they trying to sell plywood or something?
The extra 1/8" wouldn't matter. OSB is chipped and it would still punch out a hole. The test is flawed though, because I don't believe any piece of lumber has flown perfectly lengthways during a hurricane into a home window in over 20 years. You're statistically more likely to die via car crash, lightning strike, airplane crash, cancer, etc, than a 2x4 flying through your window. It's fear mongering at best.
shonuffisthemaster if that’s the case, you feel a PSL is stronger than an LVL. That’s the same comparison in beams as this test is to plywood. You are 100% wrong. PS is not stronger than LV nor is OSB stronger than plywood.
Tom Foolery there are pros and cons to both depending on what your doing. but ive heard the sheer strength figures repeated from several reliable sources, and the ratings for span strength seem to be about the same.
osb dosent do good with water, so neglected roofing for example is a place where it fails allot. however its much flatter than plywood especially in the thinner varieties. i dont think ive ever seen an unwarped 1/2" plywood sheet but for osb its the norm. given the proce difference and negligable if any proformance difference, i usually choose osb.
Psl have different design criteria. To compare is ludicrous.
The psl we used this week had modulas elastcity rating of 1.6 the lvl had 2.0 so if they had engineered the psl to a higher density it would be stronger the weaker strength is to be cost efficient rather than design a weaker member. Different products for different apps.
Plywood doesn't stand up to the weather as well as Osb. It's not just because it's cheaper it has less problems. Less call back or repairs.
Been framing for 35 years and have had to repair a lot of plywood.
shonuffisthemaster
Trying to sell a reality check,
Plywood is better than osb in almost every if not all applications,
The only thing good about osb is the price ,
It's cheaper because in the manufacturing process there's very little waste, and it can use every square inch of the tree , as well as pieces, limbs of the tree that would otherwise be basically unusable in a plywood manufacturing plant.
Here's a simple test, nail down a piece of plywood, & nail down a piece of osb, then go back and try to pull up the plywood & the osb, whatever method you choose, with care , you can remove the plywood, remove the nails, with minimal damage, possibly using the plywood elsewhere, the osb will likely be a different story, the nails will often be holding much stronger than the strength of the osb itself, meaning the osb will break, with the Nails pulling through the osb only holding a 1-2" ring around the nail, no matter how careful you are, the osb will most likely be trashed and completely unusable once you manage to get it up & clean up all the chucks that broke off.
They are not even in the same quality league.
And I am in the building & manufacturing arena. Selling & servicing all the various industries touched on above.
Wow I didn’t save any money there.
Am I missing something here, Tommy? 5/8" plywood vs 1/2" OSB? Definitely not a scientific test..
No just an opinionated old framer that knows his business
I wish osb was still 10 dollars a sheet
Wow a cannon Tommy i love how American shit is scripted
Osb is $18 a sheet as of yesterday
