Thanks Matt for your vid👍🏻 I’m a general contractor and I still always learn something from your videos you should be very proud man super inspirational keep it up. 😎👍🏻🔨
Note the "button cap" fastener attaching the wrap.....effectively holding the lexan away from the crinkle wrap...not a "real world test"....Fasten w staples and see how well the crinkle wrap drains.....need a true "gap" typically one millimeter to achieve effective drainage..
This is all-but-worthless - better than nothing, but not by much. Spend the money to install a proper rain screen assembly - probably the most important detail for a long-lasting structure.
Did a remodel on my house, I built in 1985, using Dupont Tyvek. Total waste of money using it. The stuff was all to pieces. What little of it remained whole, you can tear like tissue paper....something impossible to do when it is new. I'll never use anything but 30# black felt again. Pulled that off 100yr old buildings that looked like new. I have samples of the crappy Tyvek that came off my house for anyone that wants to see for themselves.
I have never understood this. Why make a home so air tight that you have to install a special device to bring fresh air in (in addition to any ac or heating system)? Is you have to bring in outside air anyways because the home is air tight, what’s the purpose? Water tight makes sense. Air tight..... don’t know. I know it helps with thermal performance but again, brining in fresh air kind of defeats the purpose. Help with my knowledge gap
Moisture control is highest priority. But air control is a close second so that good water control usually means good air control. However air control has been taken to extremes with dubious programs like Passive House that require less than 0.6ACH (vs code of 3ACH-5ACH) because you then need continuous conditioned ventilation to provide healthy air. The marketing for tight homes is that you want to control the quality of the air, so that you only introduce 'conditioned' air that is run thru expensive HVAC systems using high-cost devices and filters. Sounds great right? Who doesn't want conditioned/filtered air vs having air leak in thru 'nasty' crawlspaces/attics/walls? Except the problem is tight homes require difficult-to-design HVAC systems that are expensive to install (and maintain). Get any one wrong and your indoor air quality can be far worse than outside air. Plus if your power goes out (say in a storm or a heat wave) your ventilation stops and you'll need to open windows for 'fresh' air. And if you use offgassing spray foams/OSB/laminates (most houses use this crap sadly) in a tight home, and your expensive HVAC system isn't working properly you're gassing your family - the exact opposite result of what the marketing hype is about.
@@ArthurDentZaphodBeeb Thank you. Nothing says airtight like a 6 inch hole in the wall on your front porch bringing in the nasty neighborhood air with car exhaust into your home's HVAC air return. Yet, that's what poor people get who can't afford the "passive" house while they sign away their rights to claim the "green" credits they paid for so their builder can claim them. Quit putting the toxic crap into your homes, that'll solve half of it. A firefighter once told me about the toxic fumes from foams. Oh, and then there's the little gizmo that shoots plaster to plug up every tiny frigging hole so your home is tight. Then they say, let's put some bath and stove fans in because those holes are negligible. Sheesh. I love building science, but when it makes more sense, let me know.
I'm just stumbling upon polyurea sprayed on membrane....why are we not using polyurea waterproof barrier on the entire house from foundation to rooftop peak? Do we need a membrane that has some perms over the exterior substrate? Is the cost prohibitive for polyurea? The characteristics of sprayed on polyurea seem by far superior to any fluid applied WRB membrane, peel-and-stick, and certainly traditional housewrap. I haven't been able to find anything on a polyurea membrane applied on the entire house but I imagine you could achieve Passive ACH standards on an 1890's barn that has had polyurea sprayed on. The Pentagon has used polyurea for blast protection. Is this overkill for residential construction? Shouldn't we start building quality architecture with an anticipated life of at least 500 years?
Awesome Video Matt. I have experience with Tyvek and its a excellent product, its the best house wrap in my opinion. Also their flashing products for windows are great you should do a video on those. This Builders show looks sweet!

Matt, Dupont products seem great, but when someone you interview is a rep for a product, you should make that clear. Also, if there is a language barrier for a product in the US, just make a Spanish version. That wouldn't cost much at all.
Ever think about the air inside the structure. Heated and cooled. You cannot perfectly seal a wall on both sides or bottom and top. Only way to stop condensation is to completely seal house with shrink wrap remove all the oxygen and never open it.

Geoff911sc nah it works no matter what. I've used it under cedar, Hardie, t-111, southern yellow pine ship lap.

T Willey need 5 perms min by code. tyvek is around 50 perms, for faster vapor diffusion.

Very well done Matt, what handheld mic do you use.? App link or name? Great job, look forward to more.

Absolutely, between the flaws between Tyvek and Zip I have diarrhea.
Can we just quit acting like Tyvek isn't garbage?

I domt get how if air or water doesnt come through how does it release moisture from condensation from inside the wall?? Lol makes no sense.

Language barriers...The documentation doesn't come in "undocumented?"
Matt must cringe that just 5 years ago he was promoting this garbage. Wonder why he hasn't taken these crappy vids down?
Language barrier at the job site... ha! You can say that again! Those people need to learn the language of this country! USA!
