Looks like a great product and you could install the bottom course upside down so the overlap strip is at the top and tape that to the zip sheathing so any water that comes in from above is directed over the top of the bottom course leaving less water to be in contact with the bottom of the wall

I disagree with putting it upside down. That outer layer is not a water proofing. I believe the main purpose of that cloth outer layer is to keep material from interfering with the cavity layer. In other words, it keeps stucco mud from getting into the air chamber. The rain screen is designed to allow stucco to evaporate moisture from both the exterior facing surface as well as the interior facing surface, the inside surface. It is dealing with moisture at the gaseous level, not the fluid level, i.e. evaporation. When you tape that flap down because you put the bottom skirt upside down, you run the risk of cutting off that air barrior needed to expel the evaporated moisture It is also important to allow air to enter and leave that barrior from both top and bottom of wall as well as door and window opening, top and bottom. This becomes a problem with insects and small animals entering that cavity and efforts have to be made to prevent that

you could put a strip of bitumen peel and stick down, but really it's not needed. With Zip the issue with air / water leakage at the nail holes is with over driven heads (nail or screw). Sealing those is an extra step that provides security, if you don't have heads that may have driven through the barrier it's not a problem.

The real answer is the rain screen makes the holes null. There’s no hydraulic pressure to push the water in through the tiny holes. I had the same question about below grade fasteners through waterproofing. But what they’re always fastening is the drainage mat that makes their hole not a problem. I know it’s weird.

I don't think that's required. It isn't intended to be totally impermeable. this is the same with every siding and stucco, and standard practice: you usually are going to penetrate it with many nails and screws. I believe that is partly why two layers are required for stucco. You make so many holes plus you want free-draining layers. For ZIP, nails do not have to be sealed (check manufacturer installation requirements). Matt suggests sealing the ZIP nails in wet areas, such as the lower part of walls--it's an extra measure. Like ZIP itself, I suspect this material gives some sealing around the nails, due to elasticity.

Does this work with exterior insulation?

Matt, on a stucco install; do you still install Zip with a 5/8 gap between joints and tape over for expantion and contraction of wood like you would with standard osb or plywood?

If you install this under Hardi siding, do you still need to caulk the ends? is it important to keep it watertight?

We use rainscreen to protect WOOD siding, though I am not sure this product would be the best for that since we are seeking to drain the back face of the siding.

this just adds more work if you have to still then add furring strips to attach siding to, right?

Doesn't the secondary water barrier create all new penetrations in your primary zip barrier? When you attach it to the wall, all those nails/staples just penetrated the zip and there's no way for you to seal it after.

The plastic washer on the outside creates a watertight seal between the nailhead and the rain screen through the force needed to drive it into the sheathing. Zip system is osb + tar paper, so this is no different than driving a nail through an asphalt shingle into a roof assembly. As long as you are not exposing this to standing water this will not compromise the zip panel.

Also wondering about this, and although all the attention is on watertightness, I don't see much discussion anywhere of airtightness. My first guess is that we'd need something like a Zip "2.5" concept, with liquid flashing applied over lathe staples in the same way that it can be applied to overdriven nails at the sheathing layer.

Been using Mortairvent for years. Simply staple lath to it and stucco mortar adheres to the mesh fibers. Great product.

So do you put exterior insulation over the top of that? To me having an air circulation layer underneath my rockwool blanket defeats the purpose.

When I built my house I did not have a ton of money to spend on certain things, so I built my house out of real wood, and used hardy siding; years later , I threw some 30 lbs. felt paper over the Hardy board, and some Rock Wool, then 8 inches of Texas White limestone. You would never know, so do not knock Hardy board, it is the best option for starting out, and later you can just cover over it, and it is that much more protection for your home, so if your a home owners ass...., I would not ban, hardy siding, it is a great "starter" option that can be covered over, without removing it.. I do not use the "was wood" but I use the tape and other products on my real wood homes, works great, Great Show. Matt.

I used "entangled mesh" (that is what those little squares are made of on the back of the ZIP product shown here) between the roof deck underlayment layer and the actual metal roofing layer. The effect is theoretically to create an airspace between the metal roof and the underlayment that will draft a constant flow of air by convection, moving from a ventilated gap at the roof edge all the way to the ridge vent. Matt did a couple of videos a few years ago about this idea and I thought it was sound and able to do for a reasonable price. So far so good. Tech reports indicate a 20-30 degree F reduction in the structural roof deck temps in the sun.

I assume there's no R value attributed, but it has to add some to the wall assembly. Just allowing heated air to rise up and out must help. Would be neat to see some testing info.

Most houses of past years that fail in some way, often do not even follow the code or standard practice properly.

Hi Matt, this sounds interesting, but I'll admit that I'm lost. It sounds like you're saying this is code for reservoir claddings only and not all cladding types (3:52 - 4:01). A few of questions if you've got time: 1) Could you clarify which specific types of products qualify as "reservoir cladding"? I assume your list won't be exhaustive, but ideally a list of the more common ones we should be aware of would be a big help. 2) Will you do a follow-up video with guidance on detail after this layer goes on? Right now we're just seeing a product highlighted where it isn't clear if, say, battens should still be used in addition to this new layer if doing something like fiber cement siding (which I assume is considered a reservoir cladding and so will require a second WRB like this one by code). 3) Could you also indicate if there are other products out there that would be reasonable? And if not, could you indicate why this Huber product is so much better? Right now it kind of feels like this particular product is being held up without anyone (besides Huber itself) kicking the tires. And yes, I do trust Huber's testing to do a great job in their work, but as you and others on the Build Show have said -- trust, but verify.

2 issues. First is the vulnerability of the ZIP itself, because the whole principle of the ZIP system is that it is a "perfect" water barrier, which is not possible in reality. Seams and penetrations that didn't get sealed or J-rolled adequately, dirty surface before the tape is applied, nail strikes during attaching the ZIP that don't get sealed adequately, penetrations that get added later than they should ("oops" moments), etc, etc. If the siding is directly on the ZIP there is not a definitive air gap to allow aggressive drying, so if any water gets behind the siding, any imperfections of the ZIP system (which are basically caused by application, and handling issues) make it vulnerable. Second, the lack of adequate drying behind the siding will rot the siding from the inside out if water infiltrates, even if the ZIP is perfect. Probably not an issue with cement board based siding, but the ZIP vulnerabilities are not solved (nor are the mold issues). This idea is really to overcome that. Oops, I just realized this my fourth comment to this thread.... way too much, sorry.

If the wrap is vapor permeable, the moisture on the back of the siding can evaporate easily "into" the space. It's a forgone conclusion that no residential construction will keep all water out of any given wall, or certainly the interface between the structural wall and the outer veneer of the wall (i.e. the brick, the stucco, the stone, siding etc.), so there has to be a way for evaporative drying to occur easily. I have not studied this particular product but I am guessing that is the idea here, as it is with other products that seem to be of a similar nature.

Thank you for watching Jesse. You can do rainscreen air gaps with many products or even simply plywood or corrugated plastic strips. It’s the air gap that’s the code. Lots of ways to make that air gap

How long can ZIP System Rainscreen be on house and exposed?

Looks like great product. Why no suggestions of the details of top and bottom venting? This presentation is prtty much , "here, you figure it out, (and take all the liability)"

Vent grid all the way!

I love this product. So many homeowners associations don’t allow hardy planking they want to stucco or stone. This may be the answer.

Can't I just use Zip and Coravent battens behind my board and batten?

It's a must yet I never see anyone do it - except my guys who I hand the ZIP roller to and tell them the job requires it.

its like, we pushed and pushed zip system for not needing a weather barrier, but now its needs rain screen which is not a weather barrier. Also I feel like they should just make the whole product have full brillo at the bottom. Its not like moisture wont stick in there and stay only in the clear paths.

So you’re saying it’s been code since 2021? And it’s 2023 now, what if I’m building an ICF home in SoCal?

It was added to the 2021 edition of the IRC/IBC but most jurisdictions do not immediately adopt/enforce the most recent code. A new addition will come in 2024 with some changes as well.

Depends on what your exterior cladding will be. Easy enough to ask the bldg dept.

AMICO has all Vinyl components that Drain (at the bottom) and Vent (at the top) Rainscreen systems including the Zip Rainscreen - talk about best practices!

I thought the point of the zip system was to ensure water & air tight/resistant?

This product is outboard of the water/air tightness, and is used to dry a cladding system that soaks up lots of water. That's why they used the sponge analogy, but imagine the sponge was nailed on, so the ZIP has a wet sponge over top a bunch of puncture holes.

What about the penetration from the nails? Doesn't have to defeat the purpose of sealing over the screws on the zip sheathing

This may pass the stringent codes in Canada.

What a bunch of crap ! A new house won't last long enough for a person to pay for it.

One other thing they haven’t done a lot of remodeling because when you go and remove the exterior siding or even stone ,stucco the nails are rusted and you can see where water starts to penetrate.

What is this two WRB requirement that you guys talk about? I don't see any details of that showing up anywhere, yet.

What's the point of paying up (BIG TIME) for the Zip System sheathing and tape, then rolling the tape, only to now need this? I don't get it. I thought the Zip boards were pretty much waterproof on the outside, especially if you dot the nails with the liquid sealer. So: This is either complete overkill ($$$) or the Zip Boards aren't as good as previously thought. Which is it? As for the two water barrier code, I call BS. This looks soft enough to flex under the wire lathe. I’d like to see if the stucco cracks more with this stuff. Personally, if I were building something to be stuccoed, I’d go with masonry.

Zip boards are not waterproof. They are water resistant. Either Zip is just making shit for really high end all out construction because they know people will buy it being from Zip system (you see 99% new construction all zip system now) and it's something to add protection or and most likely in my opinion, the Zip system boards aren't nearly as good as originally thought over long term. Just wait till you have Zip system tyvek for on top of all the other shit lol

​@@Donkeys_Dad_Adam That air gap behind the brick is not a true air gap. It gets filled with mortar and touches the sheeting throughout the wall. Those areas will rot due to constant moisture from the brick and mortar.

What about cost for say a 1600 square foot home.

Stucco is always installed on a 1 inch EPS foam with drainage channels on the back, continuous R-Zip make no sense.

What is the cost per roll?

Water will still penetrate through because of nailing the rain screen on and what other products you put over top of that. Find away to install a exterior without nailing into the wall and then you will have achieved the goal .

All those nails are making holes in the rain screen, which is ok because the water will drain down but are also making new penetrations in the first ZIP barrier, right?
