OSB = “Obnoxious Splinter Board” 🩹🩸
Matt, you left something out. I am a retired firefighter. It has been my experience that OSB is far inferior to structural integraty during fire conditions. OSB reaches it's ignition temperature far sooner than plywood because of their physical structures. Plywood being more solid. 10 - 15 years ago people had aprox. 10 minutes to escape a house fire once alerted by a smoke detector. Today, that time has decreased to 4 -6 minutes. Because of modern building products, modern synthetics used in decor increase the toxic fumes in smoke. Also, because of the glues used in OSB manufacture it burns hotter and faster than plywood. This is a danger to firefighters because it means sooner structural failure. A hotter fire also means more damage or complete loss. Too many loses in a community may change that communities ISO insurance rating and property insurance rates rise and property values decrease. So, in the long run, is OSB really cheaper?
Great info. Never thought about that angle of the discussion.
The trend around here is to use OSB (I have a few other names for it, none of them good) for roof sheathing, with clay shingles on top. OSB is not strong enough to support clay shingles. Several years ago, a firefighter was killed while on the roof of a burning house with that type of construction. The OSB gave way, and he fell through. The Phoenix, AZ Fire Chief immediately decided that no more firefighters were going to go on the roof of housing with that type of construction. Several other local Fire Chiefs quickly followed suit. But they are still building them that way.
FF here. Been there its true. Seen platform build home collapse in under 10 minutes.
Mike, great point. I am sure that OSB being made of chips, and glue has something to do with it.
I have to agree with you. Putting OSB on the outside of a home is just stupid. It will not stand up to the sun and rain like plywood, despite if it is primed and painted.
I really think this guy is pushing a product. He is either getting a push from his sponsor or he is justifying how he builds a home.
As for me, I would never put OSB on the outside of my home, regardless if it is treated. For $2 a sheet more, I would definitely go for plywood. Yes, it will cost more but what is the cost when OSB rots through and has to be replaced before plywood? As well, this never talked about the strength of the sheets: plywood is by far stronger.
Both OSB and plywood are sheathing products which do not form weather barriers, they are for structural integrity to prevent racking or deflection of other structural members, and provides fastening surfaces for insulation, vapor barriers and siding, etc.
It should have a covering over it to prevent UV damage and water infiltration. This could be stucco, vinyl plank, wood shakes, cement board, etc, but it is not an exposed surface in permitted construction.
The videographer mentioned the fastening of siding and insulation, right? The cardboard stuff sucks 'cause it won't hold a nail? Obviously corrupted, or the negative comment has no basis in reality? Remember when he mentioned nailing to the OSB or plywood? SMH
Both are formed from wood fibres and glue, though the glue may be different, or the same depending on manufacture process, the short fibres of the OSB means that if the glue is defective at all it loses all structural integrity and quickly delaminated, exposing fibres underneath to failure rapidly.
Plywood still has continuous strands of fibre across gaps, although delaminated, and will retain some structural integrity and covering over interior strands , though not much and not as robust as solid wood,
Plywood does have better resistance to racking than solid wood when the sheathing is in good condition due to fibres oriented on two axes also.
I think it is not so much the glue, but the short fibres exposed to weathering, to allow water infiltration or heat, sort of like kindling. Try burning/soaking slivers of wood compared to a wide board, it is vastly different. OK, here's a better comparison, hold a lighter (or water) to a bundle of shredded paper, a stack of paper or a pressed log of solid fibre, one will soak or burn in seconds, another in minutes, the third may be hours. Sprinkle some glue on them all, and you will get the same results.
OSB = oriented strand board. Slightly cheaper but doesn't dry or hold up as well as plywood. Saved you 10.5 min, you're welcome
I think S for strand
It is about 30$ a board now

Can you make a outdoor shed with plywood. And can it be waterproofed? Thanks
@@mrzee321 you need to put siding on it. You can use T-11 siding instead of plywood.
I sure wish I could get plywood for 18 bucks a sheet now...
4' x 2 ' costs USD3.60 my country :)
$62 for a 4x8 5/8 panel right now where I am... It's crazy
The extra cost of sheeting with plywood is the single best upgrade you can do to your new home construction.
Look at the sheathing behind him. He used plywood, enough said.
also he's got it running the weak way plywood should always run with the grain across the studs
@@tboproductionsify1 so would you want the plywood grains be facing perpendicular to the force that it needs to withstand or parallel?
@@MeisterSexy11 Based on splitting logs with an axe, I can split a log with the grain much easier than against. However, plywood layers are cross grain or perpendicular thus giving strength from either direction. The most strength would be against the apparent grain with an odd number of layers and equal with an even number of layers.
@@tboproductionsify1 The plys in plywood are layered perpendicularly. So it really doesn't matter much.
If you're using 4 ply plywood it doesn't matter which way the grain goes 5/8 or 3/4 with 5 ply I would run with the surface ply perpendicular to framing because 3 of those plys are running the 8 foot length and the other 2 are running the width if that makes sense.
Can we rewind 2 years to these prices now 😂
*$60 sheet of 5/8 plywood*
39$ a sheet for osb
Exactly!!
@@sorgism yupp. Around $36 here. Its Ridiculous

@Matt: When I bought my house 30 yrs ago, my builder had ply sheeted the model home. I asked if he was doing that for our house. He said, no we use OSB it's the same and costs less. One day when I drove by "HIS" house being built, lo-and-behold, son of a bi*ch has only ply on the build. My house had not started building yet......needless to say my house is ply. "Do as they do, not as they say!" Cheers
I swear you can't trust a damn one of them. The mighty dollar is all they care about.
TCK, not true brother. Maybe most are untrustworthy but not all.
@@sirmixalot3332 As one in the construction world, self employed, I agree. My view is to do the best you can and not charge an arm or leg for it. Funny how it works out that I haven't had to look for work for over a year now. Past customers keep calling me to return for more.
All my builder buddys are about the dollar not long term
SUCKS
Why can’t builders provide a quote with different materials or at least a base cost using OSB and cost breakdowns for upgrades? If they quote you and say they are building OSB nothing wrong with that. But if they say they will use ply and build OSB that’s another thing.
I learn more from reading comments than the video, from folks who used in real world scenarios.
Lol yeah take advice from people in comments, not from someone who has worked in the business for years, owns his own company and builds top-tier houses. Makes sense.
You mean take advice from those that are making a profit from a product rather than those that experience the consequences of the products being pushed?
@@davidgustafson3651 he used Osb zip sheets on his own house. People walk onto job sites thinking they’re experts, this man went to school and teaches this stuff.
@@CarlosPerez-ex3ku shhhh, be quiet
When I replaced my bathroom's subfloor, I used plywood..... Because I know better than to use crappy OSB.
(Oriented Strand Board (OSB) - Terms and Definitions, Classification and Specifications) defines following classes:
OSB/1 - for general use in dry conditions, especially decorative applications.
OSB/2 - for load-bearing structures in dry conditions.
OSB/3 - for load-bearing structures in damp conditions.
OSB/4 - for heavy load-bearing structures in dry or damp conditions.
I always use OSB/3 and have never had a problem with those boards. I don't live in the usa so I don't know if the quality there is the same as here in Belgium, but I suppose it is. you should always check the classification when you buy osb plates
The simple reason it's used is because it's cheaper than plywood.
did a test laid a 4 x 8 1/2" sheet of plywood on the ground with a sheet of 4 x 8 1/2" osb beside it 6 years later the plywood is still there and the osb died a few years ago.
I can't comprehend skimping on $1200 when building a new house.- no freaking way!
If you are a developer and building a 700 unit development-I'll let you do the math.
@a w You are right on. We built our house in 2005 and our builder was from China but we didn't allow him using any materials that came from there. We used things from USA, Italy, and few other countries. During that time we heard stories of peoples having problems with sheet rocks from Cheena....Bottom line is "you get what you pay for" always watch when you hire someone to do the works. It's your hard earned money. Be safe and Happy New Year.
Your typical McMansion developer skimps FAR more on materials than that.
Even more so talking $1200 on a 7000sf house.
As a master carpenter I would never build a house that I was going to live in out of OSB.
Shouldn't build one for a client like that either. I pass on jobs that spec this trash
If Americans used concrete blocks instead of shitty ply or osb they might actually survive a hurricane
OSB won't hold a nail. For $1200 dollars saved over the cost of building an entire house it is nothing. True...you put the $1200 in your pocket but your client gets a shit built house. And you know it.
blipco5 I almost stopped watching when he recommended it.
K....And he said it with a straight face.
So the 2x2 batten fixed with 3 inch nails to the sheet of OSB I have in the garage shouldn't exist then yeah? I can tell you now it's not coming off any time soon.
Just get it wet, I dare you!!!
blipco5 as long as you properly waterproof your project you should have no trouble. I’ve seen dumb things done by hard working men because they don’t understand principles of waterproofing. These guys caulk between old siding planks and nail vinyl siding down good and tight. They are smart but not professional. A house I just remodeled had problems because the renovator decided to torque the toilets down to the plastic flange with an impact driver. Leaks are caused by men who mean well, but in theory there should be no problem with OSB.
great video. as a roofer that sheathed MANY roofs i resisted the OSB for a long time but have concluded that it works very well and as intended. it has the benefit of being cheaper and more price stable. it is also made from trees that grow rapidly on farms meaning it is as "sustainable" as all hell. all wood products fail when wetted for extended time periods...
Osb price way up this year. May as well use plywood.
Try AAC.
As a 50 year veteran of the carpentry trade, I'd like to add my two-cents worth. During that time frame, I've torn apart quite a pile of water damaged buildings. By very far, the worse damage all around, was on OSB sheathed buildings. I wouldn't use OSB on a bird house. Horrible nasty stuff, and the brand makes no difference whatsoever, I don't care what any mfg. brags, it's all crap. I could list tons of reasons it's crap, but space is limited. The argument that it costs too much is a bs argument. So maybe it might cost $1,500 over the house. Big deal. Ask yourself how much you're spending on the rest of the house, then compare. The same folks who blubber about the extra cost of plywood, don't even blink at a $2,000+ counter top!
Yep, OSB is garbage. The only place I find it is okay is where stairs, etc come together into a basement - the back end of the stairs. I prefer to have it covered and straight. That way I am not knocking my head into a jagged staircase if and when I have to service the furnace. I can bump it off a sort of inverted ramp. But, to be honest, I use plywood there too.
I agree. I put hardwood down on a house with osb subflooring and it was a dog to work with. Undulations all over the damn place. Had to put in more levelling compound than usual. Hated it.
I own a "Craftsman" type home built in 1950. ( Southern Wisconsin Madison area) Everything is 1 inch tong and grove plank sheeting the sides and even roof decking, The frame is the real 2x4's. Everything is still strait and level tough as heck. I just had a new roof put on and the roofer said he has never seen a tong and grove roof. I know the guy that built the place was quite the carpenter / farmer construction. Whats your take.
Same experience for me as a roofer when young and an HVAC guy now. OSB is notorious for fast spreading dry rot.
This is what I suspected. We don't build like this in Queensland and I just don't understand why they do in America. It just looks like you're adding problems to your build.
Good video! I am a builder in Australia where we have a preference for plywood other than OSB. We just treat OSB as rubbish.
I had to get windows covered for a hurricane. Bought the last of the plywood, then had to buy one sheet of OSB. This was in 2004. Got through the storms, put all the wood in the shed. Couple of years passed and I decided to use that wood for a chicken coop. The OSB was severely warped, the edges were expanding all around. The plywood was in perfect shape. 'Nuff said.
your dog looks very much like my dog who is half Siberian Husky half German Shepherd. at 13 months he weighs 70 lbs. we call him Houdini due to his uncanny ability to escape.
Good on you Ronnie in Florida! Stay dry and batten down the hatches, more storms are coming!
Correct. That's why houses are completely waterproofed from ground to ridgecap....
Ronnie in Florida
OSB today is much better than 10-15 years ago. Manufacturers discovered pretty quickly that if they can make OSB handle a bit more moisture then builders will use since most house get at least a little bit wet either while lumber is sitting there or during building.
However plywood is still superior no doubt, but today you can have it be rained on a good bit and no swelling or warping will occur like it dis just a few years ago.
@@Mark_Cook Must be a *very* recent improvement for OSB as a whole, because I've got stuff from 5 years ago that's pretty much disintegrated and older plywood that isn't.
5:10 why are you comparing it to the cost of a monthly mortgage instead of the total price of the house.
$1,200 of $600,000 is not a lot
Because his "friends" sell OSB.
"That's more than half my mortgage payment". Dude that almost twice my mortgage payment.
$1200 over even $100K is nothing either
@@vanspookyduke x's 3 here. Ouch. lol
I'm currently rebuilding a 150 year old house in Scotland. I decided the extra cost of plywood to be worth it.
I cannot believe he recommended OSB. That OSB shit should be iilegal... coming from a fire safety perspective!
And a health perspective
In NZ you can use plywood when treated closer to the ground, where as OSB has to be a min of 550 off the GL. Plus ply just looks nicer.
why go near ground organic material it not magic
Well, I mean, the customer selected it, right? (I would assume.) As far as aesthetics, you'll never see any of that. On the interior, it'll be insulated then drywalled over, and on the outside it'll have some kind of Tyvec sheet stapled over it, and then some kind of siding over that. No one will ever see either side of the framing product (except maybe in a garage, perhaps.)
I wish you would have addressed the off-gasing of these two. OSB is more toxic than plywood.
All exterior products have some degree of toxicity
I'm Michigan it blows up like a balloon.
@@hammer181 **more**
Exterior grades of sheathing all use phenol-formaldehyde resin. Interior grades use urea-formaldehyde resin. There are minor variations. All release formaldehyde but the urea versions MUCH more so.
@@hammer181 I didn't know that plywood was toxic.
Plywood will retain strength after water damage every osb floor that got flooded I had to tear up doing restoration it popped and deformed
chadwick hayes checkout advantech
Coming soon to the Build Show
SigneM-Prut#1 u have a link?
I’ll agree plain 3/4 osb sucks, but advantech is awesome. I work in eastern ky where it’s rainy for 3-5 months of the year and I’ve never replaced a single piece of advantech subfloor and ive replaced many plain osb and even more pieces of plywood before farming is done due to swelling and the veneer bubbling up. And as far as wall and roof sheathing you can’t go wrong with zip wall or zip roof osb. It has a waterproof membrane that is superior to anything else I’ve used, not to mention I think the zip osb seems harder and more durable than traditional osb. Point is no one in my area uses plywood for sheathing. No one. Not even contractors who build multi million dollar houses. It will be ruined before framing is done. You’ll have a better chance finding a contractor that still uses 1x sheathing boards in our area than you will plywood. A quality job in our area only uses quality osb, not plywood
Cheap osb sucks just as hard as cheap plywood, but quality osb products are better and more practical than even quality plywood. Anyone who thinks plywood is better has either never built a house in the rain or has never used a quality osb product like advantech or zip systems
So my choices are plywood, sawdust, and cardboard.
all these ppl bashin OSB, one word: Advantech
@@linds22481 You mean that stuff that costs twice what plywood does? At that price, it'd better be at least halfway decent...
@@InfernosReaper Advantech for subflooring is the way to go. Years ago I used to stock houses with drywall. there was a huge difference between regular tongue and groove standard OSB and Advantech. I'm impressedhow much weight I was able to put on the cart with an Advantech floor versus a standard 3/4-in tongue and groove OSB floor.
there is also 1x6 T&G or shiplap for both of which i wouldn't hesitate to use for a second
AAC, my dude.
OSB: Otherwise Sponge Bob/board
What
$22 a board in 2018. did you ever think back then places like Seattle and NY would see $70 a board?
What about glue content? I always assumed OSB has alot more glue creating Volotile Organic Compounds that are toxic to our health.
Exactly, that was my main concern about OSB, not many people are commenting on that.
I feel like houses are now built like the crap furniture in Walmart.
Louis Rossmann's Construction Nightmare brought me here.
joshmcej me to. I was like what’s the difference. The man wants plywood and he should get it.
I was thinking what's the cost, losing your contract.....
Between all the UK electricians I follow and the Rossman Channel I started getting suggestions in my recommendations for construction related videos.
Haha i clicked on this purposley wondering of there would be a comment from or about Louis!!
@@JM-yx1lm same, subscribed to both channels
It didn't bring me here. Looking to build a house did, but I have watch all of the Rossmann reality and construction videos, love that series!
Loving the videos Matt! Any chance a video about the economics of building a home is coming? I’m interested to know the costs vs benefits when buying vs building
I might use OSB to use as a walkway over a muddy yard, but it won't go on any house that I'm building.
HELLRAISER amen
Hell, I wouldn't even use for that!
As I understand it the fumes emitted from Plywood should not be used indoors. Osb does not emit anything.
NO OSB...NO PARTICLE BOARD! You use PLYWOOD!
In Germany this would only be considered for the most basic room dividing.. Brickwall or concrete is the main building material...
In America we lv to cut down trees
"a durable product that's going to be around for a long time" How about stone, bricks and concrete?
That's why I'm grateful to live in the house I inherited from my grandma. Brick siding house built out of cedar. No plywood anywhere in this house that I'm aware of
Other places but USA
Agree! Here in Iceland 90% of houses built are made from concrete. Now thats a house built to last! Concrete is a much better that timber for houses here in Iceland. Don’t know why there arent as many houses made out of concrete in the US. If anyone knows please let me know.
@@antonfjolnisson7574 lots of wood here available in the US so we do use quite a bit of wood. I live in a part of the country that has a I live in Seattle which has similar weather to the UK. My house is Cedar on the inside with brick siding but it has a concrete basement which is common with older houses here. I imagine would isn't use their in Iceland is commonly because there's Westwood available in the country and it's more susceptible to dry rot from the extreme cold
RabidNemo Yes old timber houses here rot a lot. I would also think the US has a lot of cement factories aswell. But the building materials differ between regions in the world. Climate has a lot to do with it.
.... I'm from Australia. We have something called double brick
@Bob Minichino Brick and mortar construction. 2 layers. Air or insulation between the layers.
Same in the UK too. Nearly all houses are bricks and mortar. Plus we have tiled roofs too. Americans always seem be replacing roofing shingles. Been in my house for thirty years and the roof hasn't needed any maintenance whatsoever.
@@elitedavidhorne8494 most new houses in the UK are framed with OSB. Then they build an external brick wall around it. If there using brick and not roughcast
@@gideonirv most new houses are definitely built using bricks and mortar in the UK. I did check the figures and apparently timber frame accounts for 25% of new builds now. Which represents a massive gain in the market compared to what it was. It used to be just the occasional self build project using timber frame. People still want bricks and mortar. They've just been priced out of it.
I hate OSB and I'd never live in a house framed in that shit.
@@gideonirv OSB is good in that context as it's breathable. That's espacially important in the damp British climate.
bottom line is do your homework with your builder...
because no matter what you pay for if it's not protected correctly you just wasted your money...
even if it passes all the building Inspection and codes doesn't mean it is just right.. you need a builder that takes pride in their work... that even if it's not code required they'll go the extra mile and take the time to do it right....... just my thoughts.....
100% agreement
Is this for the outside surfaces of the house? Here in sweden I have seen weather proof drywall used with styrofoam insulation and plaster on top of it.
Good point! My wife and I have been interviewing several builders. First, homeowners need to educate themselves; it takes several years to understand the fundamentals of building construction technology and methodologies. After being equipped with this knowledge, homeowners should feel comfortable and not intimidated to begin "interviewing" builders and asking hard questions such as: "What do you do with any surplus of materials?" I have found that this question gets under their skin and talks to the heart of integrity. If they become defensive, they disqualified themselves.
I really think the idea you present in this video of using pressure treated plywood in the first 2 feet should be the standard in the wet Texas gulf coast. th-cam.com/video/H4eUGi4uWgM/w-d-xo.html
julio Angel I like the way you think, Julio. You make good points and have the right perspective on better builders and their commitment to quality and accountability.
I also think plywood is a little more forgiving when you cut it with a saw, and doesn't flake like OSB. Also worth mentioning is I've gotten my worst splinters with OSB vs. Plywood LOL.
Try siding a house with redwood and then talk about splinters.
Your ignorant as can be.
I wouldn't even consider OSB for a dog house let alone mine..
Nice review.
In Norway we use neither. Only use (GU-gips) drywalls for outside use. The plaster boards are water repellent. It stiffens the walls in the house, and are wind protective. You have to use special tape in the joints. To make air between the boards and the wood panels (normally vertical or horizontal), you nail on 48mm batten/boards first, before nailing the wood finishing cover panels. It cost around $23 pr. sheet (normal size 1200x2700mm). On roof we use canvas/cover first, then OSB, then another canvas, then 23mm batten/boards on the studding, then 48mm boards cross nailed, then concrete roofing tiles.
those that push Cost savings over Quality are the reason so many homes are garbage, rot, and require massive repair costs.
if your building a Mc Mansion build much with better quality. if your building a small home in a poor area... sure cut costs.
In England we just use bricks lol

Just use bricks. That's a real house and much safer.
I laid the block and brick of the house I grew up in. It has weathered 50 years of windstorms, "monsoons" and blizzards, no termite nor carpenter ant can eat it.
No more flammable termite food for my housing. I have yet to see a well built house in Georgia, been here 36 years.
How about PSL, LSL, LVL and I joists??? Houses are being built like ikea furniture these days!!!!!! Just bought a $15000 dinner table and ended up finding out that most furniture now is made of particle board!!! WTF????
I didn't realize builders were using that cardboard stuff. Not being used at all around my area thank goodness.
Same here, we have earthquakes. That stuff can't have any sheer.
I'm in the midwest. I'm not a builder but I've certainly driven past a lot of new construction. I've never seen that product. Looks pretty crappy.
Never seen cardboard. But around here I have seen them only use sheating on the corners and then just house wrap + wire mesh and stucco (no sheathing).
@@Rickmakes I'm in the building supply business. Around Central Indiana almost everyone of the semi custom home builders, Pulte, M/I, Arbor, is using that ramboard to one degree or another. Hell we used to supply to this one home builder(pretty big one too) that used to use OSB 4 ft from each corner and the rest of it was 1/2" blue Dowboard 😂
They mostly put the cardboard sheets when the house is going to be outta bricks and stone
I recommend you read a book called "The Three Little Pigs"
Nice one!

Yea build with stone. And not just veneer stone that stuff is shit

Top video on a comparison between those two materials and the grades that can be attained.
Seriously this channel is quickly becoming my favoured one for information in the building industry.
Watching from the UK. Thumbs up.
hands down the best channel for the professional builder

Ryan p
@Ryan, you ought to look into AAC.
Hi Matt! Very informative video. Could you please let me know about the termite resistance for both of these materials? How much of a difference does it make by picking one over the other?
Use Bora Care for this
"You will never find a sheet of OSB rated as structural #1"..... That's all you need to know about OSB vs. plywood,...unless you just want cheap (whoops,..I just implied a large portion of america..including a lot of my friends in the business...and Matt,.has he ever used a sheet of struc-1?).
One thing you didn't mention was resistance to wind blown debris from a tornado. There have been tests done where a 2x4 was shot at a wall sheathed with plywood versus OSB. It went right through the OSB like it wasn't there. Plywood had MUCH more resistance. Also fire resistance can be an issue. OSB and other engineered products like I-joists burn hot and fast, not leaving much time for an occupant to get out or the structure to be saved by the F.D.
I often use old plywood or OSB for target backers on a shooting range and I can tell you point blank (pun intended) that OSB does not hold up as well to bullet strikes.
Also, have you noticed that some boats are sheathed with marine grade plywood, but you never hear of marine grade OSB? CONEX container floors are made with plywood, not OSB for the same reason.
Hott Puppy As someone who has lived through dozens of hurricanes and 4 tornadoes, this fact alone would sell me!
We're talking exterior sheathing, if your concern is the osb there burning too hot and fast the occupants are LONG dead from smoke inhalation.
So why not bricks then?
@@kathyyoung1774 "dozens of hurricanes"? I would not like to live near you! Or Jim Cantore.
@ 3:40 osb is not a naibase. $1200 difference in a 7000 square foot house? that's really nothing. Especially when you compare the nail pullout resistance between plywood and OSB, and the resistance to delamination. You mention that there is only a "little bit of difference" between small water leaks in OSB vs Plywood. I have found that not to be the case. Massive flaking failure of osb typically under improperly flashed windows and missing kickout flashing along roof/wall intersections. Plywood typically staining with minor top veneer delamination as the top veneer will initially shed the water and not sponge it like the edge of the OSB flakes. OSB have more exposed end grain on the surface because of the method its assembled. The perimeter edge of each flake is endgrain. In conclusion, i never have and never will use OSB for anything other than attic flooring for storage. Not even board up. My 42 years in residential construction and remodeling experience has shown me the path. Who remembers when strand board first showed up as Aspenite before they even began attempting to "orient" the strands?
Great comments from a wise old builder. Thanks
Nails? Why don't the industry have code standards for screws in the USA or does it?
Nails have been around for 1000's of years they pull out nail up drywall you get nail pop.
If it was all put up with screws it can't pop. Same thing is true with outside walls nails pull out. Screws can't it has more surface area touching wood as well as the threads locking into place if its not over driven. Its not going to pull out. If your concerned with moisture on edges seal them with a paint sealer or wax something that won't come off or water can't get past. A wax impregnated OSB would be best, better would be OSB with plywood on the outside in layers. I know they make an MDF like this and its really strong.
I just had some timbers I burnt in a bonfire with Timberlock screws stuck in them because they were so hard to get out. Ahh yeah self tapping and stroooooong.
bobbg - I’ve seen screw pops in drywall too. The more I think about drywall the less I like it. It just doesn’t hold up or stand the test of time. Nail pops, screw pops, cracked seams/corners. It’s better to cover with custom wainscoting and coffered ceilings.
Also remember screws do not have good sheer strength. Here is California we are required to use nails as they can withstand earthquakes as they have better sheer strength. Screws will simply snap.
That cardboard stuff reminders me of Celotex that was used in construction in the sixties. Junk.
In my opinion and experience (OSB) Particle board SUCKS!! I have no clue why it is Legal. Plywood is MUCH, MUCH better and more durable and longer lasting.
OSB is HOT GARBAGE. It's CHEAP and that's why it's used. Plywood is the real deal when it comes to runoff. Period - end of story. It doesn't take much for OSB to swell which makes a small amount of water turn into a BIG amount of water. NOPE. Plywood is the way to go. If anything, OSB should be much cheaper but because of the superior improvements in GLUE, of which OSB requires MORE, it's not as cheap these days. I build BOATS out of plywood and modern glues between the layers are up to par with marine grade (minus the air gaps in the actual wood). OSB is prone to MORE edge perforation by its very nature and this is why it swells and why it is crap. Sorry but plywood absolutely out-performs OSB where it MATTERS.
OSB is a little cheaper, but they charge you full price for the house -- the difference in cost goes into the builder's pocket. Any cut edge, or drilled or nail hole in OSB is wide open for moisture absorption (any waterproof coating is only on the original surface), which causes it to swell; it takes longer to dry out than plywood, and the swelling never shrinks down. If it's made from aspen or poplar, it has ZERO decay resistance. OTOH, most builders will never live in the houses they build, so what do they care?
Great informative videos, if I was teaching classes on construction and design, these videos would be required watching, along with text books.
So TLDW, pay more for weather sealing and water proofing than worry about sheathing material. And don't use cardboard.
wow. mar 2018...now it's march 2022. I bought a sheet of 1/2" CDX last weekend...$64.
dont know where you guys by osb or plywood , but in s missouri osb is about 15.00,a sheet and plywood 5/8 is pushing 50.00 a sheet..
Sounds like you could take a trip to Texas buy some plywood drive back to Missouri and make a ton of money and still sell cheaper than major hardware stores.
The only decent OSB product that I've used is advantech. I'd even go as far as to say that Advantech is superior to plywood for water resistance. Plywood is far superior to osb unless you are using Advantech. I was a die hard plywood advocate until advanteck came along. I still love plywood, it's just a superior product and worth every penny. All's it takes is one good rain storm on a bare osb sheathed roof, during construction, to see what a P.O.S. standard OSB is.
Advantech is the gold standard for subflooring, in my opinion at least. I'm not a homebuilder but I spent many years pushing drywall carts through houses loaded down with 5/8 and 1/2 in old school sheetrock, not that lightweight stuff they have today. We always got giddy if we knew that the floor was Advantech. he could load the hell out of that cart and not have to worry about it going through like regular OSB. I'm in the planning phases of building my house right now. Advantech is it a guarantee. I'm at toss up for my sheathing material... 5/8 plywood or Zip panel? 🤔
OSB is only a little cheaper than plywood with about half the life expectancy. Not for any wet rooms, like bathroom/kitchen floors. There saved you 10 minutes.
I agree. My Garage door is 70 years old and of course even though it is painted it is exposed to the elements. I have had OSB come apart in less than 10 years with similar paint, exposure situations.
It used to be about half as much.
It breaks down under foot traffic.... It is not quieter, not sure where you came up with that.
I just checked the prices of OSB over plywood, plywood is a 25% higher price per sheet over exact same dimensional sizes. only a little cheaper? Bzzz WRONG..... just for example 19/32" 4x8 sheet of OSB is $20 and plywood will run ya $25... thats not a 'little cheaper'
Syc holic, if five bucks is that much money to you, go with OSB. Imho it's false economy.
Wouldn't use osb even o. My mother-in-laws house. Cheap crap
I hear ya Dan. I don't want any of that OSB garbage-board anywhere near my projects. Once that rot gets going, it spreads to other things. It's just a mess. Not as strong as plywood, either. It's the definition of false economy.
Dan Glecier - They all have their own benefits and or drawbacks, modern OSB products are actually quite good and for wall sheathing OSB IS superior to plywood.
Yes, the problem with plywood is that its not flat. It bends in diffrent directions.
You can't use plywood for interior walls, the only way to make interior walls is to do it propper. First OSB and then drywall above that.
John Strand I used plywood on my walls. You just need a sharp planer...
The problem with plywood is that it bends. And it changes form a lot depending on how dry it is. Why, it is layers glued on layers of wood. OSB have broken all form of layers. That is why it dont bend when it gets wet. May i ask why u use plywood?
OSB is vulnerable to water damage and mold. It’s only as good as the glue that holds the wood chips compressed. Plywood is much better. Solid wood planks are best. My opinion.
Take this advice from me who used both , do not use OSB . I used it on a floor and water seeped in and destroyed my floor and I had to redo with plywood . Spend the extra and save yourself a headache .
In Germany those houses built with wood structures, like those in the USA, would be called a shed...
Hammel Bammel there are reasons besides cost why wood structures are used in some parts of the USA like California. We get earthquakes. Using stone or bricks is again the building code. Even brick chimneys are not allowed. They fall through structures like a large tree in quakes. Bricks won’t burn but they will crush you like a bug during an earthquake.
And what percentage of the German citizens can even afford a house in Germany?
@@Pube83 What's the point of that metric?
How many American can "truly" afford a house? Ever heard of the housing bubble? What percentage of American citizens are homeless?
That's such a stupid comment.
Use of buildung materials very for all sorts of reasons. Avaibility of materials, avaibility of craftsman, weather conditions, planed time of use, historic reasons, etc. etc.
American houses are not bad at all, and far from beening sheds. You can get a lot of space for your buck. Most German houses are tiny compared to American houses.
Also many framed houses use steel as part of their structure.
We blew all of your houses up.
osb should be used only under a dumpster to protect the home owner from being ripped off. That is the best thing I can say about it,
I prefer 5/8" CDX plywood with waterproof glue and 2X6 Studs especially if you want the building to last decades.
"...If you want it to last decades" doesn't account for any real hazards. Try AAC.
I agree, definitely 2*6 studs on the exterior of the house. And 3/4" plywood for the flooring and if the budget allows 3/4" plywood on the exterior walls covered with Tyveck house wrap.
@@juliorosenberg9968 23/32 plywood for flooring is perfect. Great quality and makes for a firm tough stable floor.
2x6 studs really only have to do with filling the insulation cavity to code for new building..I’ve worked on 200+ year old homes that are still standing and in great shape with 2x4 studs
Man the jump on plywood prices in mid 2022 since this video are f-ing nuts, from $20 a sheet to almost a $100 a sheet.
The best building material by far is conrete.. Seriously. 90% of house here in Iceland are made out of rebar and concrete. Its fireproof, if a fire will occur the roof, the walls everything will be there no rubble. It’s safe for firemen to go in since the the house won’t collapse. Houses in Iceland that we’re built in 1900s made out of concrete are still standing and liveable. If done correctly it’s waterproof. I don’t get it why so many houses in the US are made out of timber. Yeah sure you might be faster building a timber house than concrete but if you train a house builder well enough it can be done in no time. House builders here have built a big apartment building out of concrete in a few months. Concrete all the way.
Plain and simple, Plywood is stronger. OSB breaks easily. Plywood can hold more weight.
Bud Black maybe, but wall and roof sheathing In particular doesn’t need to support great amounts of weight, and for that matter neither does floor sheathing because load bearing walls should always be placed over joist or girders, that is taken care of by the framing. If you have a problem with things sagging because of week osb then you need to learn how to frame a house. Sheathing is not for structural load bearing it is simply a covering the same as Sheetrock is. The sheathing only adds strength to keep the structure from toppling over. It doesn’t take any super strong material to do that either. The Sheetrock on the inside would technically suffice.
Not in all applications it's not. Example, in braced wall panel design for exterior sheathing OSB outperforms plywood, is stronger and keeps a wall from "racking" superior to plywood.
I’ve went through more plywood on roofs than I have osb. Granted the plywood was really old. I’ll stick with osb.
So, just to be clear, the argument for OSB are that "when it's reinforced better, it's more durable than plywood" and when it's water treated better, it will outlast old plywood... I think the OSB fanboys might be a bit delusional
They tested and osb is stronger in shear but they problem is that they soak up any water quick so better make sure you have everything sealed properly
a LOT of water can damage either one.
YA DON'T SAY!😰
Yep - OSB or Plywood? And the winner is... Adequate Waterproofing!
I use the the best ! 3/4 marine grade teak plywood for my wall sheathing on my garden shed
Rich man
Well not much difference currently OSB is $37.65 right now...
Ply all the way. Had OSB as subfloor in two bathrooms, both rotted and collapsed within a few years from moisture.
I used to work as a roofer, and when we would use plywood, it was nice and solid when you would drive a nail into it. OSB (I still call it particleboard, even if that’s not technically correct) would be spongy when you would drive a nail into it. Even brand new.. junk. I hate osb
Yeap..just think..some morons swear by OSB for flowing yet claim" oh..just put this stripe of bs-water proofing material over it. CAse closed" (facepalm)..Nope. If Mike Holmes from the Show Holmes on Homes doesn't approve it....I'm damn surely..NEVER using it.
I don't think you have yet dealt with OSB after it gets wet!
My older brother was a roofer for most of his life and he said old houses that used planking (T&G for upscale and Ledger board for more modest homes) almost never had issues with leaks causing rot because they dried out so well. The 50's housing with plywood sheathing on the roof almost always had rot issues.
In the post war boom of 2week house builds, ventilation was not considered or practiced by very few!
Not until a building code standard was established, was this trend and others ( crawl aspace venting ) fazed out !
The beauty of the old uninsulated, drafty , all sawn wood structures , were that the wood got a chance to dry out !!
Picture those old attics , so hot in the summer the rafters would crack n pop as they dried to tinder level , and then so cold in winter, again drying out from the hyper dry air outside !
OSB CANT AND WON'T BE ABLE TO REPLICATE THIS ABILITY !!!!
CHEERS
Plywood is at insane prices right now 3/4 ply @ $100 a pop in Canada right now April 2022.
You talked about how OSB was made but you didn’t talk about how plywood was made the grain on plywood is rotated between each layer
You could have started with the price comparison and had another 10 minutes to get something else done. My shiplap sided home caught fire and on complete rebuild I used OSB vertically and plywood everywhere else. They were both much cheaper in 1996, I almost fell over when I saw your current prices. I purposely left some OSB around to get wet in the rain and was surprised it did not swell as much as I thought it would over an extended period. But it was drying out after each rain event. The 2nd and 3rd owners of my new house were, are both very happy. I visited a couple months ago. The roof sheathing is flatter than most buliders' floors.Sorry, nobody needs a 7000 square foot home. Braggin' rights and small p#$@!%s.....
I'm a young old schooler and Ive seen what they're willing to sell as material, I'm all CDX unless its planned to be cheap in which case I'm not interested. Marine grade in sensitive areas because my customers expect it.
If your doing the math on $2 a sheet I dont want to even see what the finish will look like.
Like you said, show your grandkids what quality over quantity looks like. I've seen enough mushrooms growing out of 10 year old structures.
Haha! Yeah as soon as he started talking about price difference adding up he disqualified himself as a quality builder. Geez, you saved half a mortgage payment on a 7000 sf house? THAT will make the buyer happy.
He did mention that he used 5/8" plywood on the house.
You seriouly have no idea what your talking about.....marine grade in a house? Lol right
If your company is building a 7000 sq ft and using osb .. Don't ever call me for work..
Doc Johnny
Well said. I still say... Try AAC.
Take the time to fully waterproof the material with a liquid water proofed. So if water does get behind vapor barrier the water wont soak into material. Extra cost, yes. Extra time yes. Worth it yes.
do builders today offer the option to build with tongue and groove shiplap? how does that price compare?
OSB has formaldehyde in it-hence toxicity.
Many forms of plywood as well, although OSB is going to generally be worse for any given adhesive.
I think the big difference between OSB and plywood would be linear shear strength. Put a piece of OSB across an elevated surface on one end and stomp on it and it will fracture much easier than plywood.
very true, but that's not the kind of forces plywood or osb is expected to withstand. first and foremost, both products are substrates that will be covered with flooring/roofing/siding. and for support, they have joists/rafters/studs behind them. their structural integrity is when they've been properly nailed to the earlier stated support material, and the resistance to "racking" it provides. they both do a fine job keeping straight walls straight and squared buildings square. penetration/fracture isn't really a building concern you'd apply to sub sheeting. there shouldn't be anything striking your home with that kind of force... unless a tree hits your roof, and in that case, no amount of sheeting is gonna save you from damage.
david pape OSB strength is not in its bending properties. OSB strength is in its lateral properties. If you were to elevate a 2 x 12 by 10 ft and stand on it it would hold your weight however a 2 x 12 truss would snap but yet the trust is stronger than the 2 by 12 on vertical loads. OSB is a superior Shear product.
Architect here. I refuse to specify OSB in any of my custom home builds - plywood only. OSB is often referred to as "Vertical Compost"...
Whats a step above plywood? For longevity.
@@designstudio8013 Thanks Studio.
who is roofer here? tell us what happens when OBS touch the water or is a little humidity? just got in dust, we can not compared OSB vs plywood, OSB is garbage
For shed building it's got to be plywood. OSB is inferior over time.
Question: what about concrete board?
wood is way cheaper than concrete whether u can use concrete as base for wood house
Americans could get rid of so many of these headaches if y'all just built houses with bricks and concrete.
The first thing that I wanted to say is this! Brick and concrete would be a good idea for them not to lose their houses by hurricanes...
@@chrthm27 Exactly. Hurricanes and forest fires happen there so often and they continue to build with wood.
@@AR777bomb man, I guess their wood industry is huge and they don't want to have such a loss, using concrete and bricks. I don't know what else would be the problem not to use stronger materials. It's ridiculous
They could AT LEAST use cement boards on the outside (ex. Aquapanel by KNAUF)... Still gonna be better than Plywood/OSB
Brick is such a terrible insulator though
I had a garage built in SouthCarolina and they sheathed it with osb...So the fellas had it all framed an just a bit to have all the sheathing done..It started sprinkling and I asked if they would cover the roof before all the sheathing was soaked.They replied"oh it will be fine"..Well after the rain stopped and the sun came out the next day ,the osb started swelling up...Great stuff..Not! So the attic floor was buckled and it looked like thick hair was standing up..Well it was particles of the osb popping loose ..So I swept it twice with a stiff bristle broom and vacumed it..To this day when u walk on the attic floor the wood particles pop up.To me its just about two steps better than particle board after it gets wet period.So dry in your building and have plastic ready to cover it or have saggy nasty sheathing...
I've seen a millionaire home build using 6 inch c chanel as the studs. And 1/4 inch 4x8 plate for exterior wall frame build ..it was amazing..
Being in construction most of my life, here in south Florida we won't use osb.
I used 1x pine on a diagonal that was left over from milling dimensional lumber for my sheathing.
"O" Shity Board
keenanman1000 A short but hilarious comment. Loved it. Cracked me up. Thanks.
One shitty board
Conclusion: Stone bricks are superior to both OSB and plywood!
Until the earthquake comes
@@charlesvaughan3517 I would trust brick and mortar far more in an earthquake than a construction of sticks and board nailed together. Unlike most people's perceptions, cement mortar doesn't stick bricks together, it actually keeps them apart. In an earthquake, every mortar joint acts as a movement joint, allowing absorption of forces and settlement when they pass.
As for a hurricane or tornado...!
Look at what buildings are still standing afterwards. Bricks and mortar with concrete slabs and roofs.
Plywood all day. Don't care what anybody tells you. Osb is junk.
If you want to see how the OSB started out, let it get wet a little while and watch it swell back out to the thick matte again. ...and bring the kids.
