The Perfect Wall. Finally.

- Just what is so perfect about this wall? It's very easy to connect the 4 layers of the enclosure if they are all on the outside. In order of importance, the 4 layers are:
Water Control Layer
Air Control Layer
Vapor Control Layer
Thermal Control Layer
What to do about errors in the building code? Why does the code suffer over insulation and R-Value? If I can't apply this to every building (and win every battle), what are the most important battles? What is a great reason for a green roof? How to keep your clients happy and stay out of trouble? Where are most of the problems in the building enclosure? How do you find the water control layer on a window so you can connect that to the water control layer on your wall?
All these questions are answered here. Want more?

We love your ability to pass on great building knowledge. Thank you.
I know you don't like social media but I sure like you sharing this information in your signature understandable/consumable way. You are helping me tremendously with my 1st time DIY remodel in an entirely new climate to me. Thank you very much. New Subscriber!
If every architect watched this 10 mins of building science and if every builder forgot what he was taught about putting vapour barriers on the outside of buildings in Australia, we would avoid alot of pain from NCC2019
Is that a Star Trek vessel designation?
I love your opinions, cracks me up!
Truly a living legend
I like this guy.
I love this guy's attitude. Truth over fashionable politics.
Love it.
So amazing
Now I know whom to blame for the torn rubber booth around a vent pipe on the fairly new roof on the house I bought last year
AMEN
Are there viable options for adding to an existing wall from the outside?
Water destroys everything that man builds.
2:46 The cladding should be back-ventilated and drained.
In my opinion he is a succinct genius AND a regular Joe too, ... a human occam's razor. Purchased his books: "Builder's Guide to Mixed Climates", Builder's Guide to Cold Climates and keep them within arms reach at my design workstation, right next to Christopher Alexander's "A Pattern Language" (co-authors - Ishikawa, Silverstein, Jacobson, King, Angel).
Mr. Lstiburek is quietly telling truth to power. Wish he could give me some insight in my quest to bring global warming activists to face reality: reducing anthropomorphic carbon emissions is good, but not not even close to impactful if we can not also engineer a way to improve earth's natural atmospheric carbon sequestration efficiency, which if unaltered will take 600+ years to re-balance the EXISTING extra Co2 humans have already dumped there before global temps stop rising. Google: atmospheric carbon clearing time. I am working on a method in my retirement to sequester an additional 30-gigtons annually of Co2 in deep ocean from making ocean phytoplankton happier by naturally replenishing their nutrients (at scale without producing new energy to do so ..etc). If successful with the help of a large team, we could solve global warming in 30 years and have a 280ppm Co2 atmosphere. If civilization only achieves carbon neutrality, sans our exhaling, we have achieved a hollow inconsequential political victory we might ruminate about for the next 600 years. Physics is a harsh mistress.
This is great, but how do you attach an overhanging roof over the top of everything if it needs to be supported by the structure which is on the opposite side of all these layers? If I built in a cold climate I would probably use 6 inches of mineral wool insulation and it would be hard to attach your cladding and roofing to such a thick unsupportive thermal layer. I have an idea though. What if you build a wood framed structure like a cube, then cover every inch from top to bottom with sheathing, apply a control layer (Zip, Carlisle membrane, etc), cover everything in 6 inches of Roxul mineral wool, and then build another load bearing 2x4 wood structure up tight around the mineral wool which will support the roof and those stud cavities are the vented space for the cladding and roofing?

You can't do it the way you described (with non-structural insulation/rockwool), but you can if you use rigid foam boards or other structure capable materials; In essence, this is precisely what he's railing against. Too much concern for optimizing thermal performance (insulation) at the expense of everything else.
Build monopoly style house with fake overhangs. Watch risingers video.
Apply the decorations to the house after the initial shape is created. The decorations are anything unnecessary to make the house functional from a control layer standpoint. So overhangs and such are applied after.
The point is to create a sealed structure SO effective that even if all the windows are open, the temperature doesn't change too much - if at all - unless the weather is REALLY bad. Because the house itself stays the same humidity and temperature all the time, regardless of the season, the frame will move less (which also means you use less energy for HVAC - which also means less risk of condensation in the water pipes, and so on). If the frame moves less, it stays square longer. Which means your doors and your windows and your weatherstripping and LITERALLY EVERY SINGLE THING ON YOUR HOUSE will last longer. Which means the value of the house stays high for decades to come. The individual components don't matter AS much in terms of pure performance numbers is the point that he's trying to make. It's the method and execution of making all the layers individually sealed inside each other - the exact same way you layer clothing to stay warm - that matters the most.

While he might know what he's talking about, kind of weird and confrontational presentation style. Why not describe why the layers are ordered as such? Discarding any concern about thermal insulation sufficiency is flippant at best. Also it would be interesting to hear about the materials that are best for each layer from performance and environmental perspectives. Just stating structure, control, insulation, and back-vented cladding over and over again for 10 minutes isn't actually very interesting or helpful.
You will not get that information in a 10 minute video, fortunately there are numerous complete lectures from Joe on building science. A simple search of Joe Lstiburek will give you all you want.
E=MC2 is too elegant and too difficult to explain to laypeople. Just do what he says. You think insulation is more important than water control?? He doesn’t care what materials you use since they can all be made to perform. Joe is not an environmental activist but you can find lots of them on the web.
The materials used are choices to be made based on many variables, he’s not going to do that for you. He’s seen bad code based on political leanings, his is the recipe for the best wall, it’s up to you to make decisions on “ingredients” to your taste/budget, and I’m sure he doesn’t care about you feeling he’s confrontational
He makes it interesting by being sassy
That's his shtick- wry and a bit ornery but very sage. Read his stuff as the humor may translate better on paper.
This man is God.
I wish you could sound more enthusiastic and excited about the topic.
Man's at retirement age, preached this stuff for over 40 years, yet he's still seeing these same mistakes being done by design teams/builders on a daily basis. Can't blame him for being a bit cranky about the topic.
You can’t detect the dry humor?
Has to be the most contrived biased video on walls. What about ICF, ICCF, CMU, concrete, rammed earth, aercrete walls etc. Light stick framed walls are the worst walls.
I know. And he knows it too. But the perfect wall philosophy is THE best way to get a modern stick framed house to last for decades instead of years without needing major repairs.
Too many unnecessary words spoken, that are not needed to make the point. Had to quit watching.
The man is a genius. Accept wisdom in your life.
@@Alexander-lk6yo I agree. This is just an excerpt from one his information packed talks. He’s the go to guy on this subject.
I have looked at dozens of articles on this subject and this guy made everything clear in 10 minutes THANK YOU !!!!!!!!!!!!!!!!
