How do you choose between OSB and Plywood Sheathing? In this video I'll give you some recomendations and some tips for building a tight & durable house that will stand for generations. -Matt Risinger Risinger Homes in Austin, TX
Thanks so much! These kind comments keep me motivated to make videos... Best, Matt
I really enjoy how thorough you are.
Very welcome. Appreciate your taking the time to comment with positive thoughts. Best, Matt
Although I'm just an average homeowner, I love learning these type of info Matt. I gives me understanding of our current house and what to look for if we ever to build ground up. Keep up with the great vidsl!
Thanks for commenting! Best, Matt
Thanks Chris! Appreciate it buddy. Best, Matt
Thanks Johnny! Miss you buddy. Glad that you've found my vblog! Matt
Man, only 33 thousand subscribers? Of all the people on KZhead you're probably one of the most knowledgeable when it comes to conventional framed structures. I watch your video's to get idea's on how to re-do older structures on my land and at friends places. Personally, if I was building my own home, I would just dig a basement into a hillside like a walkout basement with one exposed wall, and then use 4 foot thick tire bales with an R-Value of 160 for the one exterior wall, then shotcrete the inside and outside of the tire bales with concrete (and of course there would be a rebar, re-mesh, and chicken wire latticework to hold everything together over the bales). Then I would make the "roof" out of shipping containers. Shipping containers cost 7 dollars a square foot to buy. But then again, I'm not a normal person.
Brian the Brain thanks buddy. Let me know when your R-120 house is under construction. I need to visit!!!!
Matt Risinger Its gonna be while, but it will get done eventually.
I prefer Outsulation. Put on a 1-4" layer of PolyIso on top of your Tyvek Commercial D and you've got a super-insulated house for Texas. I also like that the WRB is fully protected. Best, Matt
Helpful, thank you. I will definitely check out your newer videos regarding how to address the bottom.
Good videos by Matt. Makes common sense for builder and homeowner.
No, that's why I use the "Crinkly" version of Tyvek called Commercial D or Drainwrap. It provides a gap behind the foam between the tyvek and foam to drain any moisture that gets into the cavity. I did another video a year ago and tested that in the field with red food dye in water. It worked amazingly well. Best, Matt
I'm not familiar with that method for termite control, but as long as it's flush with the shear wall it should be able to be covered. Matt
Great video Matt; well said. I was a home inspector for 24 years, and I totally agree. On one of your future videos you may want to suggest plywood of other soffit board in the eves. Sometimes I see ODB in the eves and it just does not hold up.
Great channel with awesome knowledge that a architectural technologist can admire.
No doubt, budgets are always the deciding factor. If I had it my way, I would spec marine grade plywood, primed 6 sides, then glued and screwed. I love that you are taping the seams on the exterior sheathing, and also along the stem wall to framing connection. I can look at your work and see that you and your team are providing a quality product; I just hope that the homeowners can truly appreciate and recognize it too. Thanks again for sharing.
Yes, looks like you are doing the best of both worlds. Good job
Great building practices Matt!!
Thanks Matt. Nice job!
Nice video Matt. Just curious as to why the lower section of the wall in Austin is so much more susceptible to moisture damage. Is it because of landscaping or soil being placed up against the wall? And if so, wouldn't it make more sense just to educate the homeowner on how to landscape properly? It would be much more cost effective.
Thanks for sharing, your a great builder!
matt. thanks for a great video. its nice to see that some home builders still put quality up front and i do like your approach to being cost effective but making that 2nd to quality. anyone who you build a home for should sleep well at night. thanks again
thank you for the information and the truth !! never stop
Great video! Writing a report for school on moisture control, will be sure to suggest this method.
Young Matt, Big Respect to Matt
Have you ever taken apart a house that had a leak? How did that OSB fare when it didn't have an air gap to dry it out?
IN 30 years of building i never used OSB for walls. it's like buying a volkswagen bug to haul lumber. Sure the bug can haul some lumber,,, but it makes no sense.
Matt, how do you address the bottom 2" of the Carisle product once exposed to the weather and uv? Thanks for all of your Build videos. You do a great job. Larry
YOUR BUILDING A GOOD HOUSE PERIOD!!!!!!!!!!!!
I'm a new subscriber. Very educational... I'll definitely apply in life
I know this is an old video but I love watching your videos, they are super informative! I have a question, what kind of tape is that joining/sealing the pieces of plywood together? Thanks
very interesting. you take great pride in your product.
Thanks for the info. Slightly off topic: do you putting furring between the Tyvek and the siding (not the sheathing) to allow water to evaporate?
I think the #1 reason I see rot/mold/decay in the bottom 2' of houses I remodel is SPRINKLERS! So many people have their sprinklers set to go off at 4Am and have no idea they are wetting down their houses 2-3x per week. This detail is meant to be a belt/suspender approach to a very common area of moisture intrusion for Texas houses. For the minimal cost increase I feel that we are vastly improving the durability of my houses with this detail. Best, Matt
I have done this multiple ways, on walls with a brick lug and without even wrapping the bottom of the sheathing before installing it with a self adhered membrane. Matt you’ve got good ideas and the areas you address certainly are issues more often then not that are not addressed. Have you ever tried sealing the wall and concrete using asphalt primer as the adhesive instead of the expensive stuff you show that isn’t readily available? Perhaps in conjunction with Grace Vycor Plus? That’s what I am thinking of using on my next project.
Matt, I saw this video years ago and it just came up again today in my feed. I like the suggestion to use PT plywood for the bottom 2’ but you now seem to recommend only Zip systems instead of plywood and have abandoned the PT plywood lower section. Is that correct? I plan to build on a lake and am especially concerned about rot, termites, water damage and air intrusion. Advice?
Good Video Matt i will use 1/2 Plywood for my 1st Build : 12"x10 ' Backyard shed with a HIP ROOF 4:12 Slope
@Matt Risinger Is the bottom 2' of pressure treated plywood on the house in this video sitting on the concrete, or hanging off it?
Matt, first of all thank you for making all of these videos! They are great at explaining why it's so important for all of your systems to work in conjunction with one another. What are your thoughts on the Huber Zipwall system. It has taken off in my location over the last 3-5 years.
I think it's a good system for "standard" homes with 2' or greater overhangs. Be sure to make a sill pan for your windows, and I'd definitely use a Rainscreen when using Zip wall. Hope this helps. Matt
Thanks, Matt. Do you still recommend using plywood for the bottom 2 feet even if the house has a 10-12 foot tall basement and is not slab on grade?
I agree the sheathing is NOT supposed to be getting wet, but my point is that plywood over the next 100-300 years is a more durable product. I use the pressure treated on the bottom 2' because that's where I've seen the most damage when remodeling. See my other videos for "proper building wrap details". Matt
Along the coast in Texas the use of pressure treated along the first two feet should be the standard. Always find damage & problems in that area
what about using advantech sheathing? better than OSB or plywood for moisture resistance
Appreciate your videos, especially since I've been in the market for a new home. I was wondering how much you know about Dryline TSX structural wall sheathing? Is this sheathing good or not really? Would you buy a home built with this sheathing? Thank you!
Hi Matt, I can't tell you how helpful your blog has been to my building process here in Thibodaux, Louisiana. I have 2' of Treated Ply along my base with OSB on top. I'm looking to use Tyvek C/D - do I really need the CWS or Ice / Water Shield at the bottom? and if so - where would the Mason plastic Flashing be applied in the process? Behind the plywood? Would the CWS still be applied over plywood and stuck to the flashing?
Good videos, my 40 yr old home in canada was built with backer board as an exterior sheeting. i eventually want to re-side and resheet the house, but will only be able to do the top half as the bottom is brick, do you forsee any issues down the road structurally only doing the top half?
Really enjoying your videos. It's a pity I have not been able to find a builder like you for my new home project in Brisbane Australia.
I like your polyguard/carlisle combo, but I'm having a hard time sourcing the Polyguard 650 LT locally (or online for that matter). Any advice on what I should look for when shopping around for an equivalent?
solid wood ship lap, like they did in the good old days.
What do you think of using ICF's (insulated concrete forms) for exterior walls, how to they compare to the walls you show on your website?
super helpful Matt. Thanks
Being a builder for many years, I can appreciate the attention to detail at what I view as the second most important in the building envelope; with the foundation naturally being the first...:)...Sweet job and if it's done right like that, you can sleep easy every night! If you build quality , they will come...
+godbluffvdgg Thanks buddy! Matt
Also have another question Matt, What type of tape is that you are using to seal the osb wood?
How would you weatherize a house with a plywood exterior (sheets) and vertical planks spaced out on the plywood siding? This is the way my house is built and I need to replace about 6 ft due to that rain damage he was discussing in that bottom zone. It wasn't weatherized correctly the first time.
Is the pressure treated plywood dry enough use off the rack? Dose pressure treated ply need to air dry before you nail it up?
I am currently in the process of backing out from a contract because the seller is not repairing their stucco properly. Your video really helps! I wonder if you guys build homes in Houston?
Sir what shall we need to provide for waterproofing in the plywood, i am going to construct a new house, so I am planning to prefer plywood for exteriors wall n this is my first project as a engineer, very tough challenge for me becz i never had experienced on this field n is my challenge to our locality with some economy we can build better house compare to made of brick....in our locality 1st class brick is expensive. So my choice is plywood. Sir I have one question ? can we afford colour paint on the plywood so that it much protective from water
here is another video why you should not use OSB kzhead.info/sun/jKaYZ92kkZ-thac/bejne.html A MUST Watch
Any future reviews on usage of Zip Sheathing? Seems to be quite popular in Austin on a lot of apartments that are being constructed.
Hey Matt hope all is well !! I am hoping you can help me out,, I am making a HOMEMADE CAMPER 16x7 ft. I'm going for the all plywood exterior "NO SKIN/SHEET METAL" except for the roof. I'm going to use regular 23/32 4x8 sheets of RTD plywood ,, I know I should be using MARINE GRADE PLYWOOD,, but there are to many reasons to list why i'm not,,but none the less in YOUR OPINION what is the best SEALENT other the Thompson water seal I can use..THERE HAS TO BE SOMETHING ,,Once again i'm only asking for your opinion,, PLEASE RESPOND..THANK YOU & GOD BLESS
what's the best sheathing option for Southern CA building where there is very little rain water. Zip vs Advantech vs OSB +weather layer?
Matt, love watching your videos and have learned lot, appreciate your work. I am building a house here in Toronto this summer and please come and visit the site if you ever plan to be here in Toronto.
Great tip thank you.
If the foundation is properly made with, say, poured concrete raised above ground level, could OSB be used from the bottom to top plates at the trusses? We're probably going to be building in a year or so and want to build green-ish with minimal waste. We're looking at TallWall exterior sheathing with raised heel trusses. It should stiffen the house, and minimize the number of cuts for the sheathing. Would that make sense?
A lot of times builders in the south use a galvanized metal strip between the foundation wall and the framing wall for termite protection. Can the Carlisle strip go directly over that?
I really like this system…only thing I would mention is to you use all hot dipped nails at the entire portion where the marine grade plywood is installed, including all hood down straps….that perimeter water resistant tape and primer is a great looking system
and prior to plywood and still a good option! shiplap!
Matt- you're such a stud! Keep up the great work!
i was looking at a brand new house the guy used OSB on the outside walls, floors, and ROOF. should i steer clear?
No reason to steer clear because of the OSB. That's the formula for 90%+ of the custom homes built in America. It's a good product.
Matt Risinger even on a roof, that stuff is okay?
randomrazr Yes, I often use it for roofs. The key is taking care of the waterproofing details. Keep it dry and it's a good product that performs.
Great video. They would never build a home like this here in the midwest (Iowa). We moved here last year and couldn't find a home that wasn't completely built from OSB, floor joists included. The place we ended up buying has been a nightmare. Built in 2000 and had to replace all of the exterior doors/frames and underlaying OSB due to water damage. Very poor quality construction compared to what I'm used to seeing in the south (Georgia), at 2X the cost. But, you have to live somewhere. As long as the house stays glued together long enough for us to sell it in 2 more years, that's all I'm worried about. The midwest really sucks. Never coming back.
Sounds like your problem isn't the OSB as much as the methods used to water proof during the build. I live in Utah and built my home in 2002 using OSB on the walls and roof; exterior walls are framed with 2x6 btw. We get tons of snow each winter and have driving rain in the spring and fall. During the summer we always have at least a weeks worth of days in the triple digits. To date, I have had absolutely no issues with water damage of any kind. As I am a retired contractor, I've built many homes in northern Utah using the same building techniques as when I built my own homes, and none of the homes I've built have had water issues of any kind. So like I first indicated... Perhaps your problem has more to do with a low quality build than the materials used.
about to butt osb to stucco for a covered patio. will sikaflex be enough sealant? i really dont want to have to cut stucco.
Does lowes or homedepot carry that compressed plywood you mentioned for the bottom 2ft
OSB is only more moisture resistant because it is coated. It needs to be coated because it is otherwise horrible in a wet environment, cut edges are not coated so water will get in there and through nail holes, for instance after a re-roof. By the time all the membranes and other systems are implemented the cost advantage largely goes away. Of course the strategies are good for other issues like air infiltration, ice dams, etc... This is a good summary of the comparative advantages, even pretty reasonable since the recent findings against OSB, and removal from some codes. Well done. Two minor points, if you see high end homes being built it is plywood, often heavy stuff all the way, like 1". Particularly in places near the mills like in Whistler BC. If you are doing your own building for your own use other factors than a few bucks may intrude. So for instance the pleasure of working with nice wood and not covering your property with toxic glues; the cost difference is a lot on a big project, but I am building a small addition there are only about 14 sheets of ply in it, at about 15 dollars more. That is more, but if I was paying someone to do it, it would be 20-40K minimum, my cost will be sub 3K, just how cheap do I need to be; prefer not to have off-gassing every time the sun hits the building; find it easier to move the lighter panels. My main point is that while production building has one set of rules home building has another. Home builders may want to think creatively about that.
that's what you need is the moisture resistance and this is one of the many reasons why i use it always
What about sheeting on the roof. Which is better. Nice video. Thank you
If money were no object, I'd go 4' with the marine plywood at the base then the rest of the house would get 1/2" CDX. As you know lumber fluctuates greatly as a commodity and sometimes OSB needs to be specified to keep the house affordable. This method gives the best of price & durability. That being said, I never compromise on my weatherization system. No matter the sheathing you use if there is a water intrusion bad things will happen. -Best Matt
Hi, i want to make some walls with OSB, but which side go on the inside, and which on the outside? (there is a side with bigger wood parts, and the other side there are smaller parts). I will put polystyrene on both sides to insulate it anyway, but in general which is the part that has to be put on the inside? Thank you
What is the saving between the method shown in this video vs a zip type system ?
Hello, I have a question. We are building a home and noticed that they are not using plywood or OSB on the outside of the home in certain spots. From what I can tell they didn’t use it in the kitchen behind the stove or in the laundry room on the exterior walls. Is this normal? We have an inspection today I just wanted your opinion before we go to the appointment.
Hello all! How do we feel about the Zip System? I'm building myself a small home in Houston and would appreciate your feedback.
Cement board or like product for lower 2 feet ? Would that work ?
Matt what is your opinion of Cellotex as a sheathing material?
Should the sheathing be tongue and groove? Should the sheathing be vertical or horizontal?
Matt - Great videos. I'm building a custom home in the NE and trying to determine if Advantech 1/2" Wall sheathing is worth the almost 2x price of commodity 7/16" OSB for the walls. My primary reason for considering it is water resistance (came from a house with moisture issues). I like your idea of CDX on the bottom. Have you considered/tried Advantech for the walls?
If I were building my house today I'd use all Plywood. Advantech is great, but Plywood has some HygricBuffer capacity. IE if your house leaks it can absorb some water and eventually dry out. I've not tried Advantech for walls, but I'm sure it's a good product. Either way, don't get your sheathing wet. Best, Matt
Are there any other stronger materials That are termite and water resistant ??
Matt What is your opinion of OSB being used on the roof? Regards Randy
Those are Jeld-Wen windows. It's my first house with them. Matt
I like this idea for my new build. Are there any concerns with a chemical reaction from the treated plywood on the bottom against an open cell foamed cavity insulated wall? Also does the open cell foam adhere to the treated wood as well since usually the wood tends to feel damp when new?
I've been doing this technique for about 3 years now without any issues. If you were concerned you could run a strip of 15lb felt behind the plywood before nailing it up. Best, Matt
Huh, I used the zip board which it’s OSB. Wonder if plywood would have been better? It’s a tiny home 12x16
I am building with KB Homes in San Antonio and they are using Thermo Ply. Is that ok? The reason I went with them is because I noticed another construction company using only wrap for sheathing and nothing else. At least KB is using thermoply and not just wrap. Any suggestions?
Thanks. Nice video.
What are your thoughts and experiences with ZIP system?
8 years ago. Man! Huber wasn't even mentioned! Who'd have guessed. Plywood is my preference- I used to be a roofer. Frankly 1x sheathing is the best.
I like Georgia Pacific blue ribbon osb because the 7/16 had a blue edge and the 5/8 had a yellow edge on it.
Matt - Great videos. I'm just started build our house, and these are very helpful. My builder is using OSB, and about halfway through the sheathing the rains came. The OSB that's hung and the remainder that in a stack has gotten wet. Is that a problem?
Hi Matt. Great start in expanding the knowledge base in our industry. What brand windows did you use on the project that has the dumpster in front of the garage? Thank you,
wouldn't exterior foam trap moisture in the house?
What about gypsum fiberglass based sheathing choices?
Is it okay to apply Copper Green onto OSB?
Matt Also, what is your opinion of post tension slabs? Regards Randy New Orleans, LA
AISLE3B I'm not a fan personally, but I know lots of builders/engineers that like them. I prefer a rebar and beam slab. They are more expensive but in my opinion better in the long term. Foundations are not the place to save money. Matt
I wish I could follow you around for a while
Matt, great channel! Are you still using OSB & Plywood, or has the ZIPsystem replaced them?
+Andrew Colwell I do like Zip but don't use it on every build. I decide based on exposure what's best for the house.
Makes sense. Keep up the great work and congrats on 46k!
Which gas less formaldehyde and off gassing?
Thanks for video helps!
