Great home, if Julia is open to it I would enjoy her and Nick sitting down with the plans or CAD model and walking through her design process. Decisions and tradeoffs etc. Especially as they pertain to high performance. Thanks for the great content.
thank you, Brian , Julia, Nick, and the NS Builds Team, for sharing the updates and insights of this amazing build; it is greatly appreciated , and immensely educational.
This content has been very informative, however, it would be nice to have the materials being used in the description so that we can do our own research and purchase them on our own.
That window/siding detail is beautiful. Please follow up with that and show window install and siding finished. Might rival the windows in a shower detail!
Why not just go ICF? I’m assuming labour cost and material cost would be much lower with ICF. I know well built ICF house here in every zone here in Canada have very minimal heating and cooling cost
What if you didn't add that second layer of plywood? Could use the Z-Girt and attach wood battens or a product like Kebony's clip-in rail system to attach siding? I am curious because I am looking for an effective and low cost way to attach vertical siding with 6" of exterior insulation that is also DIY friendly .
I wonder how they're handling the roof edge detail at the rake edges of the roof. I noticed plywood and rockwool straight to the edge. I would think a coastal area would need a solid blocking or continuous z girt parallel with roof slope for edge metal and fascia attachment
How to minimize the heat leak from gaps in the rockwool joints? If the heat leak issue big enough to be worth fixing? The rockwool joints are not staggered between layers, so that will cause a heat leak line. It looks like there will be a gap between rockwool panels caused by the 1/8" thickness of the Z Girt web and the stiffness of the rockwool. There will be variation in the rockwool x rockwool gap due to variation of where the Z Girts are installed. These points all cause heat leaks, but I are they are large enough to be significant?
I noticed the same flaw and reckon that these thin gaps (1/8" lines created by the thickness of the Z Girt) between the Rockwool panels would create a serious heat lost around the insulation. I would love to see the final result and see if this issue has been fixed.
The Z Girt is serving as spacer & support for the Comfortboard, I get that. Now you’re installing 1/2” cdx to the Z Girt, a vapor barrier sheet or liquid membrane, then cedar shingles as siding? Where’s the rainscreen airgap?
i love seeing new technology and approaches but i am curious how this compares in strength, cost, and insulation to a more pedestrian double stud wall. anyone have any insights?
The finish on the exposed comfort board is in discussion, lots of approved options. Just comes down to Julia’s decision. The top will be capped with copper
@@NSBuilders Thanks-Look forward to seeing it. I want to use a similar detail on a project, but I don't see yet how you will fasten any finish to the building without a z-girt or something similar.
I would like to know how many Sq ft , and what was the total cost . It seems this was a lot of over kill and redundancy. Was the goal to achieve no moisture ,no air . It seems impossible to be by the ocean and over time not have infiltration. I do love what you guys do , I do not understand the build . Micheal scarpino Olde house restoration N.J.
typically clips butt joints of sheathing together at center of span between rafters for more rigidity. Usually when thinner sheathing used on 24" o.c. rafters.
I'm surprised in such a highly insulated building that skylights are being used. Even the best skylights are a giant "hole" in the insulation and depending on the orientation a skylight is potentially a high solar gain during the summer cooling season and very little gain duri g the winter heating season.
Does a skylight negatively impact heat loss and gain? Absolutely. But it brings in daylight, provides cross ventilation, and makes a small space seem larger. Good design requires balancing choices across dozens of categories, not optimizing a single metric at the expense of all others.
@@julianugentarchitect bingo! I would much rather live in a comfortable house with lots of natural light, compared to living inside a sealed yeti cooler. We’re building a new house right now (just got drywall) and one of my must haves was lots of natural light in as many places as possible. We put velux sun tunnels in the upstairs interior bathrooms and the back hallway upstairs. The only “dark” rooms in the house that don’t have a natural light source are the closets, and the interior powder bathroom on the main level.
those Z girts on the roof, shouldn't they have been at an 45 degree angle or vertical, seems like they might cause water to not drain if it penetrates.
I think y'all went overboard on the roof z girts. If you understand uplift you really won't have much if any between the first layer of sheeting and the second layer of sheeting. For three reasons. 1 that area is sealed for all intense purpose. 2 the area is filled with insulation. These two actually contribute to the 3rd. For uplift to occur on the field of the roof you need positive air pressure under the sheeting. Well if air can't get in and the space is filled with insulation how are you going to get positive air pressure to blow the roof off? Yes you may get a little under overhangs if you have them but most house have them and typically you only need a 2x1 ratio of support into the roof for the overhang. Same goes for the walls. Again hard to get positive pressure in a sealed and filled space. If your roof and wall framing are sufficient to keep the first layer of plywood from blowing off I doubt the second layer has any chance of blowing, sucking or uplifting off or whatever you want to call it as long as you use sufficient method of screwing the z-girt to the framing. Prove me wrong? Think about it you only have a screw every 2 feet on the roof girts so except for the edges what does it matter if they are continuous once you put the plywood on?
I haven't been watching this channel. first time now. But at some point your amount of insulation with all this inside and outside tends toward zero return on savings during heating and cooling. 🤔
Elon is too busy buying Twitter to be bothered with his solar shingles. He needs to be able to control the narrative and Twitter will help with that. No but really. This place is incredible! I can't wait to see the efficiency numbers in real time when this home is complete.
@@alexandrep4913 I'm guessing you didn't watch the video in its entirety or maybe you just turn off the sound for the pretty pictures? Did I miss the spot where Nick talked about Mark Zuckerberg or Jeff Bezos? Or did he only mention Elon Musk? Or, are you just playing the what about-ism game? Fun game. I'll have thin my skin out and try it some day. Have a wonderful day 😊

First time seeing this type of construction, very interesting!

Nick: How much Insulation you would like us to use?
Architect: Yes
😂
Architects brother sells insulation..😂😂
Crazy amount of insulation. What are you guys building? An art gallery? Lol
Love the work you guys do btw!
Maybe a bit late but you should offset the joints horizontally and vertically on the to layers of rockwool comfortboard to minimise the bridging.
I was thinking the same thing, but I do not know how they can do it with the system they are using.
Why not just go ICF?
I’m assuming labour cost and material cost would be much lower with ICF.

Absolutely killer system.
Does this outside insulation technique end up with alleys between the vertical mounted roxul? Basically the width of,the clips?
Great work on the video! it's nice to see more interest in the building envelope.
isn't rockwall hydrophobic?
I wonder how they're handling the roof edge detail at the rake edges of the roof. I noticed plywood and rockwool straight to the edge. I would think a coastal area would need a solid blocking or continuous z girt parallel with roof slope for edge metal and fascia attachment
What is the total cost of thisi compared to spray foam? That looks like a lot of labor.

tuck tape joints before you apply the sheating and on sheating the vapour barrier? (Tyvek)

@@LukePighetti this seems like crazy overkill. Just spray foam in a 2x6 wall is really good
@@rmkensington depends on your climate. up in central/northern maine you get condensation on studs if there isn't a thermal break
How is that Z Girt working on the outside corners?
Isn't that Z-girt system thru the airbarrier labor intensive? Maybe I don't understand the detail. Can we see a sketch pls?
Where did you buy the z-girts? What's the brand?
The company is called Armatherm.
dont you want to offset the joints of the rockwool?
How much does a house need to cost before it's warm enough to survive in?
😂🤣😂 eleventy billion dollars
What is the detail at the base? How are you covering that comfortbatt?
The finish on the exposed comfort board is in discussion, lots of approved options. Just comes down to Julia’s decision. The top will be capped with copper

@12:14 No way to get moisture in there in a coastal region, ya right. That stuff looks like sponge, let alone it can't breathe.
Where can you buy the z girts?
This company is called Armatherm. STRONGIRT is another company.

Idk how many times they have explained this
I really hope you guys get sorted with the tesla roof, TH-cam has many disaster stories
those Z girts on the roof, shouldn't they have been at an 45 degree angle or vertical, seems like they might cause water to not drain if it penetrates.
Why are people still not building with ICF?
They have a lower r-value period.
I would add zip's peel and stick in just to make sure there was zero water infiltration in that roof system
@@damianokon6209 I think it may be possible for them to get in contact with Huber and work out a deal to showcase that product on this build.
Plywood, why not Densglass?

Thats a huge pile of rockwool. Id be wary of leaving it all out like that lol. Thats a good bit of money invested right there
I think z girt is a better SIP
Real shame about the view being ruined by gas silos and wind turbines, nice installation regardless .

Seems like overkill on the insulation. Especially at the Price of Rockwool. Love the design!
Lol no such thing as overall for insulation
@@daveklein2826 Joe says what? "add as much exterior insulation as you can afford"
@@GenZyannd that's what I said
Elon will tweet you when the roof is coming,
Looks like a complex cobbled mess
