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.

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.

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.

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.

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.

*$60 sheet of 5/8 plywood*

39$ a sheet for osb

Exactly!!

@@sorgism yupp. Around $36 here. Its Ridiculous

65 for 7/16 up here

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.

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.

Ryan p

@Ryan, you ought to look into AAC.

Shouldn't build one for a client like that either. I pass on jobs that spec this trash

(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

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.)

Thanks so much, that’s really kind of you!

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

Try AAC.

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.

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.

Often the first iteration of any product is overbuilt, its later down the road that they start cutting corners.

Try siding a house with redwood and then talk about splinters.

Your ignorant as can be.

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.

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?

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.

Very typical for older homes to have shiplap/grove 1x6 decking for the roof. See it all the time, though much of its in pretty bad shape now plus many of the knot holes have fallen out.

Good points. Thanks for watching

Argo Tungsten 7

Argo Tungsten must be cheap "Koch bros " OSB.

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.

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.

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

Good points

roofer of 16 yrs, 90% of my resheets are because of dry rotted plywood. due to poor venting but osb seems not to delaminate as bad under them conditions.

And also the Fire Resistant Treated plywood roof problem of the late eighties. Charring because of poor ventilation

I've built a couple houses. I've repaired a couple houses my boss built a few years before I got to his crew. When we fixed leaks where OSB was used as sheathing, we noticed the water would soak into the OSB and wreck it. But, peel it off (in dusty chunks) and the framing was virtually unharmed. We've concluded that here in western Washington OSB is great because it's not if but when you have a leak. And framing is always more difficult to replace the second time. It also stands to reason that the OSB probably has way more glue that is much further advanced than its predecessors ultimately giving it an additional life span.

I'd have to add both plywood and OSB lifespans are limited to the life of the glue. My older (96 years old now,) home has 12" to 18" stone foundation, and rough-sawn oak for all the structural joist and frame work. I have to wonder how many homes built with OSB will be standing in 96 years? Smiles!

Down south they still do that...

Brandon Upchurch I'm from New York City but I moved all around the country I've seen what you're talking about in Louisiana

That's very common in my area on the east coast of Canada, the clapboard was nailed directly to the studs but they were sheathed inside with 8" 3/4 straightedge board

Doesn't that require diagonal cross-bracing in most places now? I've seen only houses with a diagonal stud embedded in the vertical studwork, but I suppose the modern alternative is to put diagonal steel strapping on one side or the other.

They did that in my 100+ year old house. Rough cut actual 2x4s. Cross blocking more than once in nearly every single joist bay. And a diagonal 1x4 across major walls. With the clapboard nailed on with massive old 20 penny nails. It's an old way to build it but it's standing fine here in a seismic zone with just some minor plaster cracking. No weird expansion or contraction noises either.

Rich man

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

Try AAC.

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!

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.

Then that would make him a good builder. Those are few and far between.

Maybe run some activated Fibreglass resin over the lower quarter of the sheathing on both sides with a roller prior install off site allowing same to cure, then bring onto site to use on those bottom sections, there no way same will take in moisture ..bit like a hull of a boat...

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.

Whats a step above plywood? For longevity.

@@designstudio8013 Thanks Studio.

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.

Plywood isn't glued together? LoL

@@TaylorHaubrich yeah years later he can smell osb off gassing. Thru the drywall, insulation, thru the paint, and all the plumbing glue and carpet and all the cooking that's been done in the house, not to mention pet odors and laundry smells , fireplaces, etc etc this guy can sniff out glue used in osb, even tho he can't actually even see the osb, he can tell the difference between glue in osb and plywood. Lmao. Have you EVER heard such bs in your life?

Here in France if you wish to make your house airtight you have many choices in ventilating your home using heat recovery systems or just mechanical ventilation! I agree about the sick house syndrome,stands to reason if you breathe air all the time in an enclosed space you will deplete the oxygen and saturate with co2,and that is certainly no good for your health! You can have your cake and eat it it just costs a little more!

Carpeting is also a major source of indoor air pollution, some is very bad.

That's why code in Canada now calls for an air exchanger or heat recovery unit. Fresh air all year round!

Not a problem with the house. That’s a problem caused by The owner and HVAC guy not installing a HRV to bring fresh air into the home. I live in a completely air tight home, fully spray foamed from floor to peak (which I installed myself, because I own a spray foam company) and I have zero problems because I installed a HRV.

Yup... it’s why codes require a certain amount of air exchange on tight construction homes...

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. kzfaq.info/get/bejne/fpqViKqamdu7l4E.html
