Been a carpenter for 30 years, I'll choose plywood Every time, I've seen too much osb fail.
i agree 100% osb is garbage compared to plywood.
Yep. Complete garbage. You might as well make a house out of compressed dog shi^.
C J Bowen and
@John Fischer I fail to see why that's a tricky question. In my case it's easy: In mostly applications 2×8/2×10 DF joists (std.pad ,post and beam app. 2×12 DF over basements for longer span.)I have on 2 houses in a 30 year career used (per engineering) TJI's and BJI's (imagine a potentially 40' long floor joist,looks like an I beam. made with a 2×3 micro lam top and bottom cord and then a osb/ply/micro lam web member.. When they get wet or long term moisture, you're screwed. Headers almost exclusively DF (An occasional glue lam or steel I-beam for long spans) I have seen micro-lam used for headers and occasionally I've used a para-lam (imagine an osb beam)(when engineered so) headers are usually much easier to keep dry,than sheeting. So,in short Douglas Fir.
OSB is a cellulose-based material so it naturally contains mold spores. The mold spores are dormant so they are supposed to be harmless. However, when OSB get exposed too moisture those dormant mold spores become activated and start feeding off the nutrients in the wood which causes surface rot.
The one advantage of OSB over plywood is you can have a half inch thick sheet of OSB and after it gets rained on a few times you now have a three quarter inch thick sheet of OSB :)
Phill Huddleston lmao
In other words - value added product. 😁👍🇺🇸
Funniest comment I’ve seen in a long time
You fail to mention that you can use .002 thick staple method to hang paper once your get the expansion water treatment. *I forgot to mention, that this may raise the R value.
@Smarter Than You That was my point.
The title doesn’t match the video, where is the comparison?
Jordan explained the differences throughout the video.
I'm with Curt. The only comparison I could really recall from the video was that wood chips are stronger when pull stress is against the grain vs with it that but doesn't really answer the question about whether it is better or not. Plywood alternates the grains on each layer to mitigate grain weaknesses as well which also helps it stay dimensionally stable just like osb. This was a good video on the manufacturing process of OSB, but didn't really serve the title.
I agree. Very bad title name. Afrer starting to follow the channel for consistent honest results, this doss not fit. I understand you want paid ads. But this is NOT the way.
as jessie pinkman would say,i came here for some science answer shit and im still none the wiser,title is misleading. osb will swell with moisture badly if not protected,here in ireland anyway.
This video sounds like an OSB commercial. Ho hum. :)
I worked at the worlds largest OSB factory called Footner Forest Products in High Level Alberta for two years. I was in charge of the forming line and tank farm. I'm a millwright. It was a continuous press not multi opening. The plant was ALWAYS full of smoke. A severe health hazard. Most times (depending on board size) the smoke was so bad you couldn't see the other end of the plant. You can see a small amount of smoke at about the 1 min mark of this video. Every time the compensation guy showed up, amazingly we were always running the small board so little amount of smoke or we were down for "repairs". LOL. Yeah the government and the companies don't give a shit about working people. I'll go on welfare before I ever work in OSB again. Obviously they weren't doing much when you were there with the camera. Show up unannounced with a camera one day and post that. Bet you won't even get in the door.
When he embarked on the spiel about their stack emissions control and how much they spent on it, my first thoughts were "how far out of compliance were they when they got caught, how big was the fine, and how long were they given to install the emissions controls before the plant would be shut down?'
Another whining Millwright, that seems to be the MO of the trade.
@@kevincrosby1760 The plant in High Level did have a scrubber but it was way to small for what it had to do. The factory was always full of smoke and super hot because it's a thermo oil system. The gov't and industries are all in bed together, it's a fact. It don't matter what industry it is. It's all about profits/taxes and jobs. We had a great crew and a great boss but then they changed management. They demoted our superintendent and he was very respected by the crew. Then the new management started to harass us. We all started quitting and within months the place went bankrupt LOL. The entire maintenance crews (Millwrights, Electricians, Power Engineers) all quit within months. Then it was over for them. That's what happens when you hire incompetent management. That was many years ago in 2004 and I don't know if they ever opened up again.
@@kevincrosby1760 They were never out or compliance. Huber was proactive. They have had no NOV's . Huber osb is so different than the commodity stuff.
@@canadianoddy8504 Footner is running, its owned by West Fraser now.
I've been working with wood for over 40 years, the Plywood cost twice as much of the OSB maybe even more, but it lasts 20 times more than OSB, I stopped wasting time and money on OSB.
OSB is good for packing boxes but SFA of anything else.
The newer osb has higher sheer tolerances than plywood.
As far as siding goes, I'd use plywood. But the new osb subfloor is completely waterproof.
@John Doe explain glulam beams and lvl's being stronger than similarly size lumber.
Buy better quality OSB
New game... drink a beer every time he says "I won't get into all the detail"
Right? I’m watching a KZhead video about OSB. I’ve clearly lowered my standards on what I find attention grabbing, more details please.
Title should be how OSB is made
It should be that, but most of his titles are clickbaity and he won't change it.
@@MrBeaux I've noticed that too.
verry good to know how verry good OSB is made or should be made. But, it's not and never plywood. Plywood can be used instead of OSB but OSB not always or almost not, where plywood is needed.
I was thinking same thing. There was not a sliver of info about the pros and cons of this material. Very clickbaity
More like the let's show matt show. No comparison to plywood.
Wrong title... How OSB is made, not compared to plywood in any meaningful way.
CREDIBILITY, CREDIBILITY, CREDIBILITY. Once acquired, EASILY LOST, near NEVER REGAINED!!! CREDIBILITY???
Go to a tornado material testing lab. Then tell me OSB is better than plywood.
Yes, it is mis-titled. They don't even talk about a comparison to plywood, but here's a basic comparison: Like plywood, OSB can withstand the elements during construction, and for the same thickness, has the same span rating.
Proper birch ply is fabulous stuff - when you can get it. OSB is 1/2 the price and does the job for all but the finest joinery. For jointing OSB I use Confirmat screws and prime the end grain with glue before adding the jointing bead.
Demonstration of OSB vs Plywood. kzhead.info/sun/q7yqntNvomZpe4U/bejne.html
OSB when used as roof sheeting has always caused sagging valleys between rafters after several years as the heat from the shingles heats up the glue or binding agents allowing them to become soft and pliable in summer allowing it to give under the constant weight of the shingles.
That should NOT happen. The problem was probably due to poor construction practices, i.e. wrong thickness of OSB used for the span, the OSB got wet constantly, or a combination of both.
OSB cannot handle moisture it’s really crappy stuff one time use for Concrete maybe
Richard Adam Darriau - It should not be used for concrete work. What clown uses it for concrete work? For concrete work, you want to use a plywood product called “Plyform.”
@@alan30189 Impressive improvements... Long-term data will tell all. Plyform rocks... I use it often for a smooth finish. Some of is clowns like OSB for it's texture on concrete. OSB in a freezings-thaw climate has some merit because it doesn't have voids like CDX ply. That was the hype in the 80's, but once it gets wet it becomes compromised. I know for a fact. I work with plenty of forensic engineers overseeing destructive testing, and I can show you many photos of OSB used correctly, and incorrectly and too many times we see failures.... mostly installer related or on self financed projects where people are not wise enough to use proper consult. Crates... OSB is great for a crate and Type 5 structures on a tight budget. It's a bad idea under hydronic floor panels as a sub floor, or roof decking especially if it has self adhered roofing materials over it, unless it's well ventilated for thermal equilibrium. Even then, it's taking a chance because self adhered membranes are too thin. In short OSB shouldn't be used unless a third-party waterproofing consultant's specification has it listed as part of their material and method composition. If a building is to last without problems, never use it anywhere it might get wet, without a disclaimer. Under liquid applied membranes always use plywood without voids on the inner layers. In the United States fortunately the statute of limitations is 10 years... it's pretty easy to make something last 10 years. I've done destructive testing on buildings with OSB labels that are only three years old and if one's not careful you'll fall through it if it happen to get wet. Don't get me started on OSB Beams. We use them if they're specified, but only if they're specified by an engineer and architect who are using a qualified waterproofing consultant for the building envelope. I would never use it in my own house because it stinks for a long time. Now if someone starts producing OSB with a waterproof resin, keyword waterproof not water resistant, that would be a big improvement especially if it doesn't stink.
My home is 32 years old. I chose to use OSB over plywood, and have built with it over the years with NO problems . In fact I reshingled my own home 7 years ago, and had NO panels to replace. In my experience anyone not using Advantech on they're subfloors and roof is completely unlearned or plain ignorant.
As a 40 year old wood working novice, I appreciate all these techy videos... helps me learn about all stuffs better and expedient.
"There is a very precise orientation to ensure maximum strength..." *cutaway to square piles of wood chips in random orientations*
There was a roller that turned the chips in one direction.
small saw dust makes the better finish. its smooth as glass when painted. osb chips you cant put tile floor down on. wont work. water gets in the cracks and it swells it all up. big chips make a rough finish. i look at sawdust as a floor cleaner put a bottle of red floor polish, the old floor polish in ten gallons of saw dust and throw it on a dirty floor, and wow! how clean and dust FREE they floor will be after it is all swept up.
Not that I’d ever use OSB in my house; but the point of OSB IS the “random” orientations. By placing the strands in every direction, their goal is strength in every direction. My own biases against OSB is the hierarchy of durability against damage by moisture and insects: solid wood; plywood; OSB; particleboard. The more processing the fibers get, the more you’ll be relying on glues/resins/bonding agents. Solid wood absorbs water, but slowly. OSB absorbs water quickly.
@@DanielinLaTuna More surface area to absorb water. Resin is an amazing material, when combined with a backbone. By its self, it is brittle and has no strength in compression or tension. Give it a backbone like glass/carbon fiber and it is stronger and more durable than steel of the same cross section while being lighter than aluminum. Wood on the other hand is an abysmal choose for pairing with resin in structural components. But it is cheap, so cheap it is made of the garbage left over from real wood.
@@herpnderpn2484 A very good analysis!
Regarding your wrap-up: I’m surrounded by PhDs where I instruct at a university. That doesn’t mean they are better at teaching (or engineering panels), it simply means they have a PhD. So what? For a title teasing that OSB (that your channel has also referred to as vertical mulch) is superior to plywood would be much more effective with empirical data, e.g., independent lab testing for strength, durability, UV resistance, moisture tolerance, etc. maybe it’s better now, but my experience peeling back walls and roofs for remodels demonstrates a product that I can typically poke a finger through, vs plywood, that even when discolored from moisture, typically has not delaminates and is almost always serviceable. OSB is cheap. That is its sole advantage. I would love to be proven wrong, but a plant tour isn’t going to do it. I still love your channel!!!
👏👏👏
It never ceases to amaze me that ppl assume they know what they are saying but they never Ave read the spec's on a product before opening their bucket mouth full of saw dust...
@@BrianBriCurInTheOC You opened your mouth too Brian...what are you saying?
Yeah, Seems to me, the ones with degrees teaching these days (At universities) are just cant make it in the real world! Many times they made mistakes in their lessons, but oh they can be wrong can they!
@@mikeclarke3005 Those who can do, those that cant teach
When wet... Plywood warps. OSB falls apart. Hmmm. Both are bad but I'd rather have an uneven floor than a hole. lol
Paint it with Glass Fibre Resin it will adhere to the substrate you could even use a Colour pigment added into to the resin ...Job Done...
@@JeoWilson next time, try to get OSB4 ( not 12 or 3) 4 is designed for wet rooms and outdoor conditions
Keep it dry then
Such a gorgeous book - each shed is unique and inspiring, and I love all the tiny details Kotite features to help readers imagine how to create their own She Sheds kzhead.infoUgkxe9yi0sulKgsp0VJJCIrLWWkvVqcU7LFR . The feature on Dinah's Rustic Retreat is like something from a fairy tale. It's really inspiring to see how creative all these ordinary people are in making beautiful and useful spaces on a modest scale.
Ive been a carpenter and owned a remodeling business since 1985. We have used OSB wall and roof sheeting for the last 25 years apx. Recently I had a customer who requested standard plywood. It bowed, sagged between trusses @ 24 on center. de-laminated, was wavy between studs and was an awful choice, especially if you are planing on using horizontal siding or Hardie. Standard ply used to just swell on the edges when wet, now it just comes apart into individual pieces. The OSB is more rigid and does not sag. You do have to make sure it is kept dry, it does swell when it gets wet. Other than that, love it.
OSB is junk! Engineers won’t spec it for building envelope restoration. It swells, delaminates, rots much faster than ply, when used as roof sheathing it often develops mould on the underside in the attic. It’s heavy. Fir plywood is a far better product.
I'm in the middle of building a house with Zip and have been very impressed with both the product and the company. We have had several major storms roll through and it still looks like the day it rolled off the factory floor. My OSB subfloor (not Advantech unfortunately) on the other hand is in rough shape.
Zip is OSB, as you know. I've used it as well and achieved good results. It's one tool of many, many available options. I will say I worry long-term about how that particular home will hold up.
Which one is better then? I didn’t hear anything about plywood? Eh?
1806StoneHouse he definitely did not mention plywood in any comparison ever....not even once or a percentage of. This is a commercial
Clickbait title.
40 years in the construction industry and all i can say about OSB is BS. I could go on for weeks about what a lot of crap that stuff is. Now microlam and paralam are respectable methods of using wood. this ranks with propaganda because it is so cheap.
CREDIBILITY, CREDIBILITY, CREDIBILITY. Once acquired, EASILY LOST, near NEVER REGAINED!!! CREDIBILITY???
Because they know it is superior and this is an OSB commercial.
Saw this stuff at the Oregon coast on a build. It was exposed to weather for 6 weeks...looked worse than Edge Gold. Buckled everywhere.
Why 6 weeks ? We're the builders on strike? 😄 Shouldn't take that long to get dried in ! Or as we say in Australia, to lock-up stage
@@colstace2560 average 4000 square foot home with 4 car garage up here in Northern Arizona (US) takes about 3 weeks unless yoi botch your sub contractor scheduling. But high end osb subfloors are a blessing in Monsoon season.
That seems like a worse case scenario where the people doing the project don't care, and left it like that to spite the owner... The stuff is designed to fit at the bottom of your floor level and have something over it so it never has water on it. If you can avoid getting water on it.. it should last damn near forever. Then again, if you building a place where there might be flooding, you might not want to use it there because of the threat of having it soaked or submerged.. I think you need to treat OSB like you would treat your tools.. with the understanding if you use it wrong, you will break it.
Most of Oregon is currently a “builders market”. They can name their price and schedule right now. A lot of builders will start multiple projects and come back to them at alternating schedules. In addition, one days worth of rain on the Oregon coast can equal one years worth in some parts of the country.
@@stoweman34 So there actually no malice intended? It's just that hard to find people to do the work? If that just the conditions of the work in Oregon, why don't they just not use it then? It seems like it could a total disaster if between the time its installed and the time its protected that you might have to replace the OSB product on the house.
The Achilles heel of OSB is it’s brittleness. Under movement stresses (as in an earth quake for example) it wants to break away from the fasteners that hold it down especially on structures of more than one level. For this reason, codes should require plywood on both sides of corners and both sides of doorways and maybe windows. It also quickly turns into compost when exposed to recurring moisture and it increases in thickness if temporally exposed to moisture (it swells up).
Rarely saw any of how it's made. Should be OSB sales pitch. Useless.
Pretty much. Alot of conveyors
Drive some screws and yank them out test. support the ends and weight the middle to breaking point test. Rig up a fold test to test shear or twist.
You forgot the most important test to a typical builder: the cost $$$ per sheet test.
@@valkyriefrost5301 LOL...yep
Very well explained Matt, I'm an engineer and I worked in the development of it about 20 years ago. Congratulations!
that's not Matt :)
You kind of lost your "engineering" cred when you didn't even pay attention to who is hosting the video- I hope you paid better attention in school.
Excellent articulation of the subject at hand which makes it easier for viewers to follow and understand!
Osb when it gets wet or damp will flake apart and rot. No way is osb better than plywood
Here is the UK (the damp island) we have osb3 that will easily outlast plywood in wet conditions. Its widely used in construction
This should have been the title to this video. All those click bait banners are a waste of time.
@@darrinpatterson2764 The only OSB you can get in the U.S. that is 'water resistant' is 'Marine Grade'...which is on-par cost with old-growth plywood...which outlasts OSB-Marine by 5x. If you're paying out of your own pocket for it, the choice is OBVIOUS!
@@skeetersaurus6249 well here in the UK ive seen osb3 as we call it out last marine ply in Maby side by side situations so maybe what you use in your area is substandard compared to our local area. As a builder and joiner I know what I would use hands down in what is a very damp country
I would be curious to see how this AdvanTech stuff holds up. I would hope it has evolved somewhat in the last 30 years.
I wouldn't use OSB on a bird house
I have...it doesn't hold up in that application, either.
ive seen that. it gets very fluffy after a while XD
Osb is trash
That's cause you bought into the 'plywood is the best' Lie
The last time I did a project with OSB, about 7 years ago, it got rained on for about 2 minutes and every bit of it that got wet doubled in size like a sponge within about 10 mins. It seemed worse than particle board. I was furious. Its gonna take a lot to convince me to every try it again for anything.
What is it's purpose? What does the manufacturer recommend it be used for? i'm not in construction
Double? 1/2” to 1” In 2 minutes I doubt that story teller
You bought cheap low grade stuff. You gotta buy the good stuff if you want the good stuff. Top of the line osb is superior to plywood in most of the most important aspects
Here in Germany we mostly use OSB and not Plywood. However there are several quality classes (1 to 4) of OSB. You usually cannot get stuff below 3. And 4 can also be used for moist areas and rooms like a bathroom.
Fascinating. Thanks Buddy!
Next video "Is particle board stronger than concrete countertops?"
Well those are weak (unless some steel matting is in there)
Looks like you found someone who may want to pave roads with osb
No but lighter. High quality particleboard is quite strong and water resistant BUT most particleboard is only a 3 layer process. Good quality particleboard uses a 7 layer process.
Conclusion: Plywood all the way!
All the way to the dump
I upgraded my 2700sq ft build to 2x6 and plywood only 1/2 sheathing, decking, and 3/4 subfloor. The cost increase was $8500 give or take. 6 months of house payments, worth it.
In the early 70's we built a big housing development in San Diego called Tierasanta. About 500 homes. Couple year later they where having birth defects enough to be concerned. They tore up all the OSB floors, it was full of formaldehyde. They have formaldehyde free carpet and padding at the same price but you have to ask for it. They don't tell you.
The OSB is flaking apart on the benchtops at a place I volunteer. That is besides the holes where the OSB broke through. I'm replacing the OSB benchtops with two layers of 3/4" plywood and a 1/8" layer of tempered Masonite. OSB is only one half step not quite as bad as particle board.
Was this just an add for chip board
Yup. This channel is quickly rotting out.
Fantastic! Very cool! Thanks for the deep dive.
Sadly too many "contractors" purchase all their materials from the big box stores and judge everything by those products. A multitude of products are available from quality companies are available, but, many want to save a couple dollars only to cost them more later. No quality contractor should purchase materials from the box stores, blindly believing they are getting anything but low quality products. As always you get what you pay for. Great presentation with someone who appreciates quality and is willing to have an open mind.
I agree with some of what you are saying, but you're casting too wide of a generalization. I wouldn't be a 2x4 from Home Depot unless I was short on firewood, but have seen Weyerhauser OSB and USG sheetrock there
@@BrianKrahmer Mfg make different grades of product for different markets. Just because it has a "name" on it, doesn't mean it's the top quality that mfg produces.
@@wags99999 i've heard the same thing about electronics at walmart, etc, but have never seen any proof of it. feel free to produce some spec sheets that prove what you are saying
One sheet of 19/32 from lowes, one sheet from 84 in the last week. The lowes plywood has their color banding applied to the ends for the cashier to identify more quickly, the G-P UPC tag on both pieces was the same.. There are three choices locally, Lowes, 84 or an independent store. Besides the higher price I stopped going to the local place after multiple attempts by them to off-load their twisted up splintered junk on me. The same CANFOR branded balsa wood bs that lowes and 84 both sell. At least with lowes you can sort through the fire wood pile to find something decent, 84 to a lesser extent and the local guy will absolutely throw a fit if you dare sight down your material before accepting it.
KZhead recommends these videos to me once in a while. Every time I click one it's clickbait. It's the main reason I haven't subscribed and won't.
Sorry, I didn't hear a thing that led me to think, "OK this is truly revolutionary stuff, it ought to hold up for at least a couple hundred years come hell or high water." On the contrary, I suspect that it will turn to moldy mush if it gets even a hint of water on it. And taking a look at the pictures didn't convince me that the strands were all that "oriented". They looked pretty random to me. Scattered just like sprinkles on a cupcake. What wasn't talked about at all, not even mentioned, was all the outgassing from that polymer resin. No assurance at all that this stuff isn't going to gas you in your sleep if you build your house with it.
dlwatib wow that’s a very extreme assumption....
The Sky is falling The world is flat!
Probably shouldn't use carpet, laminated flooring, many kitchen and bath cabinets, etc, because they all off gas. If your not dead yet from your house, most likely it's ok.
My mentality is facepalming itself every time i read someones comment mentioning the 'off-gassing' of plastics let alone spray foams. The worst thing spray foam does is just smells bad if it was applied incorrectly, its not going to kill you in your sleep or even if you were awake and just sniffing the minor amount of the said gassing.
Randomness is a quality in and of itself.
Lots of comments about mistitling, and I agree, but I just wanted to say what a great explanation of how the stuff is made, beginning to end. Well done.
Really cool seeing that factory--thanks!
I realise there are different grades of OSB as shown in this video but structural ply is just so much stronger generally , easier to work with and better in moisture resistance . As a carpenter we have all used particle board flooring and even the best moisture resistant versions are inferior to plywood flooring . OSB is different again but similar idea . It is just so much more reliant on glues / resin and usually fails earlier than plywood . My old boss used to refer to it as " compressed horse shit " ..... !!
What makes Huber’s AdvanTech products different than other Saw dust boards is the genuine science and Adhesives/resins they use in the manufacturing process. This is why they had to come up with their own Adhesives to use in the building process (see Matt Risinger’s video from last year detailing why he does not use Liquid Nails or Locktite PL on AdvanTech products). Old Timers will never change their thoughts and ideas because they refuse to learn science.
@@BrianBriCurInTheOC the reason most believe plywood is better is from personal experience using both.
@@BrianBriCurInTheOC You forgot to mention the fact that those resins and adhesives are TOXIC and harmful to human health. Off gassing is gonna be recognized as a problem only when people start suffering health consequences, just like the cigarette industry.
Reptilian Lord I’ve had more wise men tell me to NEVER ASSUME... SO I will not assume you’ve attended any Leadership, Management or Communication Classes that give the wise lesson about assuming something... Yes PAST product have been TOXIC, BUT a cut of coffee is more valuable than what you said. I trust Matt and Huber! Two things hold back advancement in Construction in The USA. HACKS NOT KNOWING WHAT THEIR DOING & Ole School guys not willing to learn. Matt’s bank account shows he knows what he is doing. Oh and him hiring a new guy too.
Sawmiller Smith Have you used this specific product??? AdvanTech by Huber? Once again you ASSUME you know what you are speaking about but...
Jordon does a great job as host. A natural in front of camera.
I used this on my subfloor up here in the Pacific NW right before we got dumped on with rain. Even when we couldn't get the water off we ended up with only about 1/16 of swell on A FEW edges and other than that the whole thing is strong and flat. I actually have a few pieces that have been sitting outside in the weather as temporary decking for about 4 months with no deformation or structural issues. Plywood will often return to size and shrink back down, but I've found there's more squeaks and when it swells it delaminates so the damage is already done.
Osborne is shit should be outlawed
Osb
I won't hesitate to use OSB for a subfloor. Right after laying it down, I throw a layer of deck sealer on it. I figure it's all the weatherproofing it will ever need, and doesn't cost that much.
@@fucyu3924 Osborne is awesome moron
My dad built a doghouse out of OSB a couple of years ago. It sits outside in the rain. He did paint it. However, it has held up just fine in the elements. So obviously the best use is to put a covering on it whether that is paint, siding, shingles, etc.
Also - make sure it bears no load
@@maverickstclare3756 False
OSB could use some inner strength such as some kind of structured webbing and overlayed with some form of laminate even bonded plastic.
I sheeted a wall with OSB. The glue did not protect against humidity. It got wet and it cost a fortune to take it out. Plywood has a chance to dry if a leak occurs.
its easir to get of tho> you can sweep it off the flooring.
That plant is incredible!
I have a small 4 inch square section I cut from a sheet of OSB that has a bolt impeded in it. I saw its expression within the board as I was cutting it with a circular saw just an inch before hitting it. I know its rare but the bolt must have been dropped onto it during the pressing process. The bolt's about 3 inches long and maybe 3/8's diameter. I keep it with the message written on it that says "Check before you cut".
Where's the comparison between this and high quality plywood? I have NEVER walked over an OSB board that felt stiffer or better than same thinckness plywood.
Walk on some Advantech and you'll change your mind asap.
@@skliros9235 but is it better than same quality plywood at same thickness?
@@AluminumHaste Yes: OSB depends ENTIRELY upon the resin used to glue it together. You can buy Crap, and you can buy good stuff. The resin is superior to the wood, but costs more $$$. You get what you pay for... Shocker huh?
Well then, where do they sell this product and is all the OSB at home depot low quality? Just about all of the OSB I've ever bought at home depot has been lousy but I recently bought some plywood there that also started to delaminate as soon as it got wet.
@@dangrimes5078 Ding ding ding: Give this man an award. Used to be able to buy OSB for outdoor use. I still have some that is sitting outside for last 30 years used as a splash shield for my firewood. Same spot also has plywood of different varieties and most of it has died(delaminated and blown up). Some has not.
oh my god, THE BEEPING...
Incredibly annoying!
If you have a home on a solid concrete foundation you can use OSB on the outside and inside of your walls, you can add sheetrock directly over top of the OSB on the interior, of course you need to add a vapor barrier and appropriate insulation. by adding OSB on the interior you can use smaller pieces of sheetrock because you can drill the drywall directly into the OSB sheating. Of course you have to make sure that building codes OK the process. If you are going to do this on a regular foundation you may be able to add in the crawl space or basement an extra layer of concrete block or poured extension to hold the weight. If doing an arch on the interior or curved wall you can use a mesh similar to gutter guard mesh between the two sections then layer with plaster, it is time consuming but worth the effort.
Thank you so much! Without you here in Italy such kind of info seems impossible to find! Here people still think that you cannot build a “real” house just with wood ! Even engendered wood! I wasn’t able to find the fantastic I beam with osb and wood you use in your beautiful houses! Looking crazy for info about it! I am ready to produce bymyself for personal use! Thanks again to teach and show so much! Wish you best from A desperate “wannabecarpenter “from Italy :)
That was way cool, awesome video. Interestingly, back in the 80's plywood mills started using strands on the inner layers of ply, they we're just bigger than osb chips. Strand plywood became the norm because of how the timber industry was affected by the tree huggers and stricter regulation.
If i get the chance to build my own home i would never use osb plywood. Ever. I have built everything from garages to churches and always found osb to be crap
AMEN!
Very clear and informative presentation of the OSB making process. As a board I was doubtful about its durability, this has given me confidence to use it as a Home DIY user. - Thanks. Bill, Cornwall, England.
Very informative on OSB. Thank you for that. Is there a particular step in manufacturing that makes this cheaper than Plywood? Not as much log handling and individual manipulation?
I'm taking a guess by saying you can use a poor grade lumber for making strands where plywood takes a better grade of trees to get decent veneers.
I don't know anything, but it looks like they use much thinner logs for the OSB. It doesn't have to grow as long and if you need to clear out small trees anyway, they can't be used for plywood but you can turn them into OSB.
I built a 3 drawer 3x3 dresser one time for my daughter. It was in a box that was 5 inches wide 3 feet in length by 3 feet tall. OSB material. It weighed 630 pounds. Collapsed after a year when all the screws tore out.
Jordon: "This check ....I'm mean tour has completely changed my mind on OSB"
Damn. Your narration was awesome, and mike and sound eng were tops! Great job!
Nice presentation - very educational - great presenter - Thank you!
Building a house. Going with Advantech glued floor decking and wall sheathing all the way.
Where I live I have been watching them build many new homes. These are very large expensive houses. I have yet to see one sheet of plywood on the roof or sides. I can't see the floor but I'm sure it's also OSB. So you can hate OSB, but all the homes are built with it now. It's kind of interesting that home depot carries way more plywood than OSB. I guess when people have a choice they want plywood.
Your right. The high end OSBs like Advantec for subfloors, is a superior product, that can take being rained on for months without damage. That's why it sells so good. It's much better than plywood, and anyone saying otherwise doesn't know construction in our modern times.
In some places, they build entire apartments out of wood framing and sheathed with OSB
A suggestion --- It would be helpful to print two ruler lines on the board .. to help people make the cut or nail a support rail or something .. You can experiment with prints with visible inks and another with inks that one would need special glasses to see .. For those exposed boards that they do not want to see the ruler lines ..
Highly flammable and termites love it. I prefer insulated masonry block or even 'Faswall' which is a block made withmineralized wood chips.
I just had to replace a roof in less than 15 years with all the OSB failed
I had the Twin Peaks theme song stuck in my head the whole time. need to rewatch.
Lol
Wow amazing how original. I think I saw a OSB was made on This Old House a quarter of a century go
Excellent job Jordan!
Problem with OSB is that it is extremely flammable, and condos that have used it flare right up in massive fires.
Not nearly as flammable as that pink foam board they used to use for sheathing.
Yeah, never mind the pine subfloor, pine studs, pine joists...
@@9mmkahr Yes that's stuff as flammable to, but the OSB is unbelievably flammable and quickly flammable spreading flames a lot quicker.
AND crumbles like toilet paper when wet!
Osb sheet burns 2 mins faster than plywood. everything we build out of is extremely flammable. I've seen plywood assembled homes go down in minutes.
DON’T WATCH! He doesn’t answer his headline question! You could have had me as a subscriber but you blew it.
When you go to the lumberyard and grab say osb you really don't think of how much thought and process time goes into it .great video I'm always learning . Thanks
Excellent episode!
No way in ........ I just removed that crap for my floors. It is a nightmare. I think it would be very beneficial to never have this problem child in your home.
You must be talking about "pressed wood" made from nothing more than glue and sawdust. Not osb.
I’m a Canadian Forester... about 20 years ago, the Minister of Environment, referred to OSB as Oriental Strand Board. Oh my. Just reminiscin’
When I started out, houses were sheathed with gyp board, which is sheetrock with a waxy paper on the outside. A little perspective on home construction. In the 20's , 30's and 40's houses were sheathed with nominal inch thick wood, 1X10s. They were and are sturdy.
And most of them are still standing today!
TITLE_ 3of10 // CONTENT_ 10of10 . . . . THANKS for what you guys do, very helpful/interesting !!
Reading through the comments here, it looks like he failed to make OSB look better than its horrible reputation as the crappiest building material out there. He didn’t even answer the video title’s question.
Mr Innovator Wayne, I don’t know who this Jordan guy is; but it’s not Matt
Better if it stays dry!!!
Well I'll say that particle bord, widely used in prefab Insulated panels and floors in mobile homes and modular homes are much worse. A small undetected leak/moisture and it crumbles.
@Matt Risinger: The real question is will it wick up water, swell as well as fall apart like old OSB. We want to see these test done to huber regular OSB and ZIP.
One idea i have for Advantech to consider would be coating/encapsulating the wood pieces in a poly material instead of just resin. If they can make it waterproof rather than water resistant? That would upgrade this engineered product.
OSB is like hot dogs, its all the leftover garbage that you cannot sell for anything else. I use plywood for making fixtures when water jet cutting and some of that plywood stays soaking in the tank for weeks or months before getting too cut up and destroyed. It does swell slightly but stays together. Recently I had a shipping crate made from Huber green zip OSB show up and I recycled it by using it for making a fixture. Less than one day in the tank and it was swollen, crumbling and done. The roof on my house was re-done in 2003 and they replaced any 'bad' plywood with common 7/16 OSB, walking on it I can feel the softer bouncier spots and know exactly where they replaced anything. OSB is junk, it always has been and always will be.
What would happen if they put liquid foam with this wood and then formed and pressed and dried it.
When osb first came out I said it would be inferior and that has proven to be correct, I put a sample in the back of my truck for a couple of weeks and when I pulled it out it was 3 times the size it was when I put it in😯, in a perfect world it might be acceptable (not) but in Florida with the humidity no way, mold and mildew set in to osb quickly and it fails structurally when it swells causing fasteners to loosen, not okay in a Hurricane, last I heard our County had banned osb
I have had particle board with metallic chips in played havoc with router and saw blade not so good if in wet areas in time starts to grow and disintegrate.
Very interesting. How would I tell high end OSB, from the low end stuff? Is it actually stronger than plywood? If so, how much stronger?
Not when you add water it's not
yea right, I threw an extra sheet up on my scissor lift as a cover to keep it dry here in PNW, didn't even last a month, maybe better in the desert but I'll keep with my known quality, marine grade in trouble spots, CDX everywhere else. OSB is for temporary barriers and floor protection.
I wonder a lot about OSB's off-gassing of VOC's from the adhesives.
Plywood has adhesive to bond the layers...
FYI, it was addressed though not explained properly (I manufactured PB and MDF for 12 years, and except for the desired milled fiber geometry, the processes are identical). He spoke some in the middle about the adhesive, and said they’re using MDI instead of less advanced adhesives which might be easier, but not give the same longevity. That’s nonsense. The adhesives used for 50+ years were all UF (urea formaldehyde) resins, and they always made a durable well adhered product (not discussing the pros and cons of specific engineered, or non, products, they each have good and bad about them, and good reason use each for specific applications). The real reason for switching away from UF adhesives has to do with formaldehyde emissions. As California legislates environmentally in the wood products industry, so too eventually goes the whole country, and beginning 7 years ago began the transition. At this point, whether MDF, particleboard, plywood, or OSB, with the use of newer adhesives like MDI, the products do not emit any more formaldehyde than do trees naturally in the forest. MDI is quite hazardous to work with, requiring respirators and special cover when in close proximity, when it is still wet, or most dangerously when it is in aerosol form, but once in contact with moisture (it’s catalyst) and cured with heat, it is inert. Babble, blah, burp, fart (oops!;)
Bill Reynolds that’s great info thanks! And with today’s HRV/ERV systems homes can get a lot healthier. Home Depot sells a formaldehyde free finished plywood and it’s awful. It has all these voids, delaminates, splinters. So it’s good to know the other manufacturers are coming up with alternatives.
MrBrianDuga Home Depot is likely selling a non A grade product, possibly what’s referred to internally within the industry as, “mill run,” which means it has some percentage of defect, or one of the of the downgrade (subpar properties, sold at a discount) categories such as “shop” or “utility.” Resellers who sell direct to the public often seem try to pretend or ignore that grades are known, even to act unaware that they exist at all, and as such, if they don’t tell you, you don’t know what you’re getting, nor if they’re banking or passing along their savings to you.
Oh, and I promise you, the manufacturers always know what they’re selling, what the specs and properties are, and clearly label. When manufacturers sell direct to industrial fabricators, or to retailers, it’s all above board, and with discounts given, or when they’re dissatisfied, and when they’re not, they file claims against the manufacturer. Large industrial customers are often very involved with the manufacturing process, demanding special properties, trials to achieve specific performance, etcetera.
Was building for a company and we put 5/8" OSB on on the roof, before we shingled it the inspector came out and made us rip all of it off and put 5/8" Plywood on the roof, maybe it was just the local code, but the "White Hat" was no happy!!
Wow in the 12 minutes I took to watch this the price at Home Depot went up 2%. Actual prices at H.D. Jan 17 2022 $33.98 for 3/8 osb. Feb 2 $40.98, Feb 14 $45.78. (35% increase in 28 days.) Gonna hit 85.00 this summer again. Glad I bought the 160 sheets I needed last October for $29
If it goes to $85, solid pine is Thicker and cheaper.
When is the strength test comparison coming?
Obs is garbage
Comparison? There isn't any.
You just gotta believe the sales man, he wouldn’t lie. I’m told OSD helps with erectile disfunction as well.

"Could OSB be BETTER than Plywood????" I get it, the title is in the form of a question because you don't have any idea. NEWS FLASH GENIUS: We don't know either.
News flash, no it isn't.
@@iseverynametakenwtf1 It's a lot more sustainable than plywood and it's a lot cheaper. For many applications that makes it 'better'. I've not used plywood for more than a decade - it's been superseded for most building applications by OSB. There are facing applications when ply is needed. Both materials have grades and if it's going to get wet for long then those grades matter.
@@Wookey. I've used "Silent floors" it's an I Beam style using OSB. If you are banging on the wall/floor (as in nailing) they can pop apart. I don't care how cheap it gets, it will never outperform plywood.
I know, it's not
So when a roof is being constructed in South Florida and before you know it a heavy down four comes down on it before the composite board is protected with roofing material , is it going to absorb moisture ? is it going to be ruined ? how long can it be out there in the environment without being protected and still be viable ?
Fascinating!
OSB has a very bad reputation to overcome. Typically OSB is considered cheap and prone to water damage. Nice to see a video on how it's manufactured but I would be far more impressed by an independent plywood, OSB longevity comparison study.
EclecticFortune2 - as a remodel contractor, I've seen LOTS of deteriorated plywood or plywood that has delaminated.
@@micahwatson9017 Thanks for the reply Micah. What are your thoughts on plywood vs OSB. I suppose the resin or binding agent determines the longevity. Your thoughts will be appreciated.
135SoHc Obviously you've don't read well and don't do it much. Advantech is NOT PARTICAL BOARD nor is it cheap OSB. YOU BB ARE A TYPICAL GUY THAT LEARNS HOW TO POUND A NAIL... AND THAT'S HIS EXTENT OF EDUCATION IN THIS INDUSTRY.
HEY I CAN TYPE IN CAPITALS ALSO!!!!! Where in this sub-discussion is advantech being mentioned ? Advantech is not cheap, locally it costs the same as real T&G plywood (both being nominal 23/32) so no I wont use it because real plywood is better. Other than shingling I cannot remember the last time I used any nails... Squeaks, creeks and pops are not something I like to come back for, GRK FTW! I suppose your still hanging drywall with nails right ?
135SoHc Try in the first minute of the video! Jordon clearly states in plain ENGLISH this video is at Huber's Plant where they produce AdvanTech and Zip products. Once again, ADVANTECH is made with resins which are much more stable and resistant to water damage. Someone else said AdvanTech is nearly as costly as plywood. Well if you had an open mind and if you could read you might take the time to LEARN it just could be even better than plywood at resisting water damage and equal in strength. And if you had an open mind able to learn you would have viewed Matt's video where he presents Huber's own adhesive that functions much more effectively than Loctite's best because the Huber product is designed with the Resin ingredient in AdvanTech. As far as Zip goes -- Zip is coated and with installation detailed paid to the required items using the Liquid Applied sealer... Maybe it is time for you to join the modern world which knows the Earth is not flat any more...
You really need to cover osb asap.
I wonder if the differential drying of the layers to achieve post tensioned material?
Great job on the video. Another thing they stamp on the panel, is the span rating. OSB is an amazing product. I've sold tons of it, over the years.
Matt, sorry for all the negative comments here. I enjoy all the information you bring. Thank you. I’ve learned so much!
sorry for yourself
Nice description of the manufacturing process, which should have been the title of the video....Not a word of the comparison of the plywood vs. OSB. Apparently, Mr. Risinger is morphing into a hired salesman for various products.....Too bad he doesn't cover alternatives like Hempcrete....
Turning into a hired salesman? That's exactly what his channel is now.. you can't get through a video without prominent name brand placement. It's almost suspect when a company does do a lot of marketing.. if the product is good builders will use it.
This is fascinating!
Dropped a piece of 7/16 Zip in a bucket of water, and left it there for about a month. It swelled maybe 1/8" thicker, and still had a lot of bending strength resistance. Not scientific, but enough to convince me that Zip is much better with water resistance than other OSB's I have seen.
