My wife died in 2013 of brain cancer, but, thanks anyway.
Hey I just want to say +1 to James Allen. I spent months combing their gemstones selection until I finally found the perfect ruby, which they set into the band I had also chosen. We get tons of compliments on the ring. When we had the wedding band made to match it a lifelong jeweler said it was one of the most stunning rubies he'd ever seen. It took him over a month to source one with the same attributes. Anyway, I figure you sponsors probably would appreciate this so what better way to support you guys. Rock on.
Cement that is binding/drying releases due to the chemical processes between the minerals and the water Carbondioxide at massive scales. So making tons and tons of concrete is a climate factor.
I love that you are willing to take the whole crew to these listen-and-learn experiences. Pays dividends in performance and morale.
Thanks John… I think we all did actually learn a lot of this thing and glad we were able to go
Priceless Info! Everyone on the same page. What A Team!
Perkins Brothers seem like an A+ employer to me. That's why their crew is so good. They find and keep skilled people with good attitudes.
Hey Guys! I work at a concrete research lab under Dr. Tyler Ley (look him up if you want to learn all about concrete).
Concrete and other materials like mortar are made of cement, aggregates, and water. While the energy and fuel used to mix and transport the concrete contribute to emissions, the main source is the production of the cement (ingredient in concrete). Cement production accounts for 6-8% of total human emissions. Cement is made by burning limestone and other materials in large kilns. Of that 6-8%, 60% of it comes from the decomposition of limestone at high temperatures in the kiln. The other 40% comes from the fuel used to heat the kilns. Now, once the concrete has been mixed, poured, and hardened, concrete will overtime absorb CO2. 60% of the CO2 lost during the burning of the limestone will be absorbed. This process takes many years.
Great videos guys!
and that absorbed CO2 is what's going to wreck your rebar and crack your concrete.
I love Tyler’s videos. As a civil engineer he has some great videos on concrete.
@@RenovationDestinations34only if you’re using metal rebar 😊
Hey guys. If you are still interested. The concrete industry is responsible for 6% of all carbon dioxide emission worldwide. The production of 1000kg concrete produces 700kg of carbon dioxide.And those numbers are only for concrete, not for all "cementatious" products. :D (all those numbers I learned at university)
Much love from Germany
The majority of that comes from heating the raw material to produce clinker which gets processed into cement.
I think this is true, and there are strategies to reduce the amount of CO2 from concrete (mainly by reducing the amount of Portland cement in it). Fly-ash are the ash leftover from coal fired power plants and is a waste product. I believe you can replace a decent chunk of Portland cement with fly-ash and it reduces the overall amount of cement in a building.
Compared to comercial construction, residential doesn't use as much cement. However some folks work to see if they can find ways to use less concrete in construction.
Instead of slab on grade, a couple houses have had their exterior walls (and interior load bearing walls) rest on footings and the ground level subfloor floor is plywood on top of 2x4 sleepers on compacted gravel. Kinda a wild idea but would be interesting to see if it would work.
Great to see training in building. In Australia the building standards have crashed since I retired. Our kids just chase the big dollars with no skill. Love your channel. Cheers to all.
I've seen concrete as high at 11% of global GHG emissions. We really need to have less of a reliance on concrete as a foundation solution
People think the env impact is large, but in reality concrete is pretty green because of how long it lasts. Spread that impact out over the life of the structure and it will show as better than other options. Concrete is almost all new construction.
My first week at Delft University of Technology (40 years ago) to become a building engineer. Asks the professor the 200+ students in the hall "Why are people complaining that their houses are leaking and their cars are not". His answer: The first thousand cars of a new model are leaking too!! But those leaks result in design improvements and the following millions are 100% waterproof. However with houses we often build single ones and at most a hundred. I will never forget !!
Love that y’all invest in educating yourselves and the crew. So many don’t.
Would love to see an episode every week that is called "Let Jamie Speak" And its how he goes about his processes etc. Would be very interesting.
Happy Birthday Eric I hope you had an amazing day and hope you have many more. Much love and Big Hugs from Michigan
Steve Baczek is a super intelligent engineer, and the other three are good too, but I’d prefer to hear Jamie talk as any one of them. He’s smarter than most and been out in the field doing the actual work for years. Should’ve featured him and Erik
Haha… thanks bro
It’s actually a bit of a myth that passive house is twice as expensive, it’s about 7 to 10%
And that’s really because you’re not changing much outside of the amount of insulation, add good air control on the outside and the quality of the windows and doors.
That adds about 15% of cost , would you get a lot of that back by having a smaller heating system, reducing the cost again.
There’s a wonderful paper from BCIT that show is exactly how much more tends to cost.
Obviously not everyone has 7 or 10% extra, but it does pay itself off over time. Through lower bills and lower maintenance.
And it does significantly increase the comfort in the home as well.
Also, if you do sell the house , it’s still more valuable, so the time you live in the house doesn’t change the payback.
It still pays you back even if you move .
I have to say that this idea of high performance building really needs to catch on. I think it's easy to get carried away in the technology but sticking to basics what we are really talking about is thoughtful, forward-thinking practices as opposed to more expensive materials or equipment. I'm in Canada, and you wouldn't believe the amount of new builds with drafty areas or cold spots because of folks cheaping out on r-value, for instance. Also, roofing? Why are we still putting roofing material up that has to be replaced every 20 years? I could go on and on and it probably differs quite a bit depending where you're from, but I guess above all what I love most about this channel is your willingness and often incessant need to think through these details and make it right, as Mike would say.
Love the idea about a semi-annual or annual home inspection checklist. If you guys make one, I'll use it.
Awesome that you guys could do this. I've always wanted to be a framer like my dad, but the majority of building crews have a sort of culture about them - that's all I'll say about that. I'd quit my job tomorrow to work for a crew like yours. Kudos.
Hey guys, this training is really good. Here in Brazil we use 90% cement in construction, all the walls are made of fired clay blocks and joined with cement. All wall finishing uses sand and cement. The Romans who invented concrete. Big hug from São Paulo - Brazil.
Concrete is the third largest CO2 emitter behind coal and oil. From my understanding, there are two main environmental issues with cement production. These don’t include the issues with procuring the other materials for concrete. The first is the heating of the kiln with fossil fuels to generate heat to cause the reaction creating lime; a main component of cement. The second, and less avoidable problem is that the reaction releases CO2 as a byproduct. So, even if the plant was powered by renewables, the carbon output would remain substantial. I hope this helps, and there are many other places on the internet to find more information on the subject! Thanks for the videos!
Because of the ground freezing so deep, here in the north, and the added challenge of hydraulic clay in some spots; we have to be able to put the perimeter drains far enough below the bottom of the footing to make sure ground water and frost can't heave the foundation and crack it! On the other side we quite often have a crawl space or basement! So building footing forms is sort of a must!
The Tretheweys are awesome!!!
Eric I keep telling you this but honestly if you ever thought about doing quarterly teaching at your local high school. I’m serious tech our young people. Do an apprenticeship program, the state will give you money for there salary during the summer months. Get them out of the house and learn something. Your to good of a teacher, father, mentor to not challenge some you men. My father always told me, no matter what you do in life always learn to work with your hands. Jamie can take them to do shop in his workshop. Again, awesome, awesome show. 😊
i’m living in a zero energy house in europe (zero energy = passive house with solar, producing more energy than the house need on yearly basis) and it cost me only 20% more than a standard low energy house. Proof again that standard european house are way more efficient than standard US house. It’s great to see that it finally start to be a real concern in the US 👍
Good to see y'all keeping up with the future of building. As you said, let's find a way to increase the performance and minimize the cost. Most don't care about a passive certification but we want a comfortable living space. Thanks for your videos, entertaining and educational.
Who was the lady at the picnic table at the end? You should have introduced her. Great show. My wife and I love you guys.
Thanks Mark! That’s Charlotte who works with Sashco! She hooked us up with the tickets for the symposium.
Baczak is a god, I feel unrelieved with you all falling asleep, as I am an electrician and know he has great thoughts and methodology.
FACTS!!! 🔥🔥🔥
Always interesting. Always entertaining. I appreciated JohnO's input too! Thanks !
John-O’s observation about the “Book” is spot on in light of what you all were saying about the architect and value adding. Many many people struggle with reading the Bible. Preachers who help the people understand it do a great service for God and for the people they help when they can give the understanding. Great connection John-O!!
In Charlotte, there is only one custom builder that I am aware of that builds to the Passive Certification. Walking through his current custom house build was amazing. One of the many take aways was the increase in the air quality inside the home. This is a factor that everyone will want in their home and it seems building to Passive standards is the future of construction.
Do you remember the name of the builder?
Not a very active builder. Kind of lazy truly ;)
Do you mean the decrease in indoor air quality? As you tighten up the air flow you get a loss of air exchange with the home exterior. Construction materials, paints, insulation, etc. , and even home furnishing, such as carpeting may degas volatile compounds that can degrade the indoor air quality. Definitely worth considering as local/state requirements for new builds are trending to "tighter" housing construction requirements to improve energy efficiency. Sort of you "fix" one problem but you create a "new" problem.
Steve Baczek is the goat. 🐐
@@munkydotorg Absolutely...Steven Kasay with Kasay Custom Homes....He is currently building a 7,200 square foot house that will meet Passive Certification. Beautiful home that should be finished in April 2024.
Happy Birthday, Eric. I enjoy your channel which means I’m impressed by you and your team’s work. Many happy returns!
Love Steve Baczek - pay attention to this guy!
I'm not a construction person but I did work for a Contractor friend for a couple of months as a snark in 1977 (busting down lumber piles, slinging boxes of nails up to an upper level) and now enjoy watching your vids from literally the ground up.
I was at a country Holiday Farmer's Market in Santa Cruz County where I live this past Sunday and saw a tent made by," Vervor". Thought to myself that's a brand name I now recognize so that tent must be of high quality
Thanks for posting this video.
Hi Guys, The way you work together is the atmosphere I try to promote on my construction sites over here in the UK. We build a little different to the way most of you build in the US, we preferer to have at least a Brick face building, but use timber frame internally a lot more these days. You are quite correct in saying that we have much higher costs for our energy usage, and need to be very conscious for out Bills. My wife and i have purchased an old house build in 1937. A solid Brick building, which we are flipping, where I tore out all of the old central heating, the old plaster and installed insulated Plasterboard to the exterior walls and run new electrical supplies for electric heating to each room. A few other alterations as well to improve the insulation of the house. The whole idea is to move away from the old conceived idea that you need to have a Central Heating system. These are designed around hearting water when you don't actually need it and an amount you will never use. we use an electric shower unit and instant hot water heater under each sink. Our electric Bill is a lot lower than the yearly average in the country. Just wanted to share. Cheers.
The last guy speaking about high performance HVAC system is on This Old House. His dad is Rich Tretheway, the plumbing and systems brain. Little FYI. ❤️❤️👍👍
ITS THE SAND!! Cement uses a finite resource. A very specific and diminishing resource - fine sand only found in some places. This amongst other factors as well.
To make Portland cement-the most common type of cement-powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete
Hey thanks Shawn… did not know all of that!
@@PerkinsBuilderBrothersand the net energy to mine, crush, heat, package, and ship “concrete” from origin to retail consumer is a massive amount, to say nothing of the CO2 contribution the product itself has on the environment. That’s why it’s the most impactful element of contemporary construction materials.
@@DrMJJrShipping and packaging is actually pretty easy for cement when compared to most things. Since most of the mass of concrete comes from aggregates and water, neither of which have very specific requirements (usually), they can be acquired on-site through local sources. Only the actual cement is required to be manufactured and shipped from a potentially long distance. Most of the emissions from the process come from generating the energy required to heat the limestone to several thousand degrees to actually create the cement.
My dad was a gifted woodworker but my interests are more at the "crafting" level and even I learned new things watching your video today.
Thanks for sharing what you know and do. Even us non builders love your videos.
Thanks for the positive comment!!
I love your channel guys. Being in the military, I've lived all over, in a lot of different builds. Look through the lowest of lows and the highest of highs. You cannot stop "mother nature". I think you guys are in the right direction, by asking the questions. Right? As with most trades, in each step, you have to ask "what if". As a tradesman you stay 10 steps ahead and you have to take into account cost? Is the juice worth the squeeze? It is all about risk management. I assume, as you design, build a house, you have to manage risk. I don't build houses but I love watching your crew do it. In closing, let Jamie talk!, he may be long winded, but the information is not lost among us. Shout out to Ray also.
Look you have a great crew. Let them all talk! You perkins bros. are great leaders but you guys are not afraid to ask why. Never stop asking why! Why waste time adhering to a plan you don't understand?! If I ever meet you guys on the street, first round is on me! Love you guys! Keep it up
The last house I built for myself had 300mm insulation under the slab and 285mm rockwool insulation in the outside walls. The ceiling had 500mm rockwool insulation.
It was the outer walls end ceiling was a bit extreme for Sweden but the insulation under the slab is pretty much the norm.
In order to reach overall efficiency demands required by code at least 8 inches or 200 mm under slab insulation is needed in Sweden. But going above is cost efficient in a cold climate, especially with underfloor heating. I’ve seen up to 400mm or 16”, but our heating requirement here in northern Sweden is twice that of Perkins bro’s neighbourhoods.
Happy Birthday Bub! 🎉🎈🎂
Thanks Erock!
Wounderful ! LOVE YOU ALL !
I work in aircraft and we refer to your Value Eng. as “Design to Build”. We’ve done this over the last 20 years now and it makes a tremendous difference when you hit the manufacturing floor to build the product.
My husband and I built our house and have zero roof penetrations. Our plumbing vents and bath vents and ERV vents go out the side wall. Plus we only have 2 roof lines and they do not intersect. We did our research before building. I'm so glad you do some CE. You can pass the information on to your clients and then they can make an informed decision. Good job guys!
I do love the way you all work. I'm a tell me why kind of learner. I need to know why, so I can understand how. Sometimes the architect hasn't ever built anything and doesn't know real world applications and has never come across problems that can be seen on the job site. It's important to work together. I have a theory that everyone within a company should work every single job for a couple of weeks so that they understand everyone's roll and can work together to be more efficient. I've done janitorial for years and people don't realize that changing a couple of things about how they do things or not do things, even placement of a trash can, can make it easier for the cleaning person. Retail is the same way, always work together to understand the needs of everyone. Sorry for the speech, but I think it's great how you all do that intuitively.
Me too. Gotta know why
I'm in a completely different industry, software engineering, but I'm the same way. I ask questions until I understand the underlying ask. A lot of times that knowledge doesn't change much in my proposed solution, but more than a few times I saw that the client's actual desire didn't line up with exactly what they were asking for, so I proposed a completely different solution that better fit their needs and they ended up much happier than had I developed exactly what they asked for. It's also a pretty regular occurrence for me to have comments on proposals like "if you make this one small change, it's going to be much easier to develop and maintain" which is my industry's equivalent of value engineering. A lot of that comes from adapting visual designs into functional websites because, like you said, the designers haven't actually built a website before so they don't know what it takes and the pitfalls associated with it. It's my job to align the the design with what's possible and practical.
Re: Value Engineering - Architects will design something from their software and catalogs with next to zero knowledge of what products are available and if other than specified materials, that are available, will do the job, or do it better. The real “value” is in knowing what may be less money than specified, available and still fulfill design criteria.
Hope that makes sense. Great videos as always! Keep rockin’!
I am a huge fan of you guys. I love that you are getting more educated on the building science, and that you are helping educate us and others.
Thank you.
Fun time. Be kind to each other. Stay safe. Love to all
Many of the speakers at your symposium publish Build Show Network videos on UA-cam every Tuesday and Friday. I enjoy their videos and having had 3 houses built, I'm all about water control, air sealing, insulation and environmental comfort. However, I agree with your assessment of most folks not owning a home or living long enough to break even on the cost of super high efficiency equipment or solar panel equipment. . You guys do a superior job on flashing details from what I've experienced/seen in the past. Keep up the good work and entertaining and informative videos.
Yes.. it's all well and good to seal up the building envelope;
* what about ventilation and air circulation to control humidity and availability of natural light. The two elements in elimination of building moulds.
* cooking
* showers
* window sizes (natural sunlight)
* human habitation per zone (exhalation)
* leakage of services
All contributors to respiratory and associated illness.
🌏🇭🇲
Seal up all the holes and then pay extra for a ventilation system that uses extra energy. You know it makes sense to someone.
Awesome! Do more videos like this one. Thx!
In one of Matt Reisingers videos they about the potiential health risks of spray form insulation due to outgassing. The context was a customer who had big problems with allergies and avoiding sprayform insulation was part of the solution. Apparently foam from a spray bottle was ok though because those get perfectly mixed in the factory but foam mixed in a truck just outside has the problem of improper mixing because you can never get it perfect. This leads to outgassing overtime wich is considered a resperatory health hazard. And I get that
Also a lot of the blowing agents have high greenhouse coefficients.
Happy birthday, Eric .Big fan... great channel ..
In the Netherlands some houses are built 8 meters/yards below water level. So we do care about draining! Sometimes the houses sink over 1 meter (3ft) over a period of 10 years...
What a beautifully done ua-cam.com/users/postUgkxYGamVaHfdHiPlAQaLa7zkwR02OKpGYDU ! The instructions and the photographs are brilliant. It is thorough and genuinely informative. Ryan got another winner! No one does it better!
That Building Preacher observation was spot on!
When the big New Orleans build back was happening, I was surprised that they were not using forms for footers.
Your comments helped me, a yankee, understand why.
22:31 looks like Ross Tretheway from "This Old House".
I use black flex seal on the top of all my joist before putting down deck boards. Easy to apply and since it's a rubber membrane it beds the decking well.
I'm no expert but the process of making cement basically takes calcium (Ca) containing rock (often mostly calcium carbonate ; CaCO3 - limestone) through a high temperature baking process that drives off some of the carbon dioxide (CO2). The resulting powder, which is very reactive, gets rehydrated by the addition of water and reacts with the water and makes artificial "limestone" rock. The baking process is responsible for the majority carbon dioxide emissions.
Vox has a great video that explains cement emissions, but like you said, it's all in the manufacturing process. ua-cam.com/video/asLWBGtAhZk/v-deo.html
CO2 it is.
Eric, I’m sure someone made the connection with Ross Trethewy and This Old House. Ross is following his father’s footsteps as it were.
Happy birthday Eric 🎉🎉 I do watch every video and I lve you jamie and boys ❤❤ . Cannot wait for the next video xxx
I saw that on another channel where they blasted their new windows with water and, sure enough, several of them leaked. It was good to see that they fixed the problem before they move onto the siding.
I'm sure someone else has already said so, but Ross is Rich Trethewey's son from This Old House and I think it's more like "Tre-thoo-wee".
Was surprised to hear that bungled name pronunciation get messed up! I just figured everyone who likes to build stuff would have grown up watching TOH and would be familiar with Rich and how his name is pronounced.
@@billymacmakes and course everyone should know how to pronounce cabinet "draw" like Tommy and Norm.
At 17:33 when you mentioned deep freeze and the need to go down below the frost line, this is not always the case. In certain soils like Hard Pan Sand, some maximum depths for footers are just 8". I built a home on Higgins lake, Michigan, and there the hard pan is 17' deep so the maximum I could go down for the bottom of the footer was 8". 12" x 8" footer needs to be 3,000psi with 2 - #5 rebar & 3 courses of solid filled block with 1 - #5 rebar in top course, with 8" J-bolts every 4'.
Tre-thew-ee. The great Richard Trethewey’s son 😂
One of the criticisms I’ve read about foam insulation is that the spraying must be exact since you are essentially manufacturing the foam on site in your home. There’s been cases where the foam never fully cured and off gases forever. I’m sure it’s rare but it is alot of chemicals being sprayed into your living area. A combo of rigid and spray foam seems a good choice since the rigid is manufactured in a factory under strict conditions.
Concrete requires sand and that has become a precious commodity!
Not sure I get the no holes in roof since these guys have solar panels on the roof so there’s gotta be some penetration!
Another point is that the foam is bonded to every plate and wood framing forever. So if you wreck the house later on it is impossible to split it from the foam and to reuse or recycle things out of it.
@@DeCSSData Theres been cases where the foam was sprayed but not precisely at the right temp or ratio so the stuff just never cured and kept off gassing. They literally had to remove the entire roof and restart. And to your point. In the case of a roof if you ever wanted to replace a single sheet of plywood or OSB it would be a bear to remove plus you'd make a huge mess and have to clean that up too. Its too expensive a solution and has too many issues in my opinion
I believe the sand for concrete is gathered from freshwater areas like river beds and riversides. The ecological damage of that harvesting is usually severe.
Thanks for taking us with you !!!! Cheers to all the sponsors toooo. Happy Holidays PBB!
During COVID I dove down the rabbit hole of high performance building (that’s how I found you guys and binged through your videos!). Huge respect for Joe Lstiburek of Building Science Corp, with kudos to Matt Reisinger too. Check out Joe’s video on “building beyond Net Zero” to get a sense of key pieces of the technique. It does present new challenges for mechanicals (ERV ventilation, especially). But it means buildings that will last a long time.
And I’m a Southeast whitewater kayaker! In Bryson or the Ocoee quite often! Build my dream mountain house for me!!! Thanks for such awesome videos.
Here’s the video I mentioned. It was a webinar by Joe Lstiburek, and it covered in very straightforward terms the basics of Building Science. Their website has more articles. And they have a lot of good humor in them!!
m.ua-cam.com/video/sBcNFeiWjrg/v-deo.html&pp=ygUYQnVpbGRpbmcgYmV5b25kIG5ldCB6ZXJv
One thing I’ve noticed from your videos vs. Joe Lstiburek’s principles is that you all don’t usually add a drainage gap between the sheathing and the siding. Furring strips or special mats designed to provide this gap are typical (you did have a house where LP smart side sponsored and had you use a beaded wrap, I think. Joe would say always use the gap and it controls drying and any water infiltration well.
Thanks Tom.. NOC!!
Lots of good information in that one. I’m going to have to watch that again to gather it all.
It's great that you guys hang out together in work-related situations too - builds camaraderie! Even though you have to listen to Jason's "jokes" 😂 I'd add.
Happy Birthday Erik 🎁🎂🎈
Hey guys, I made it!! It is always fun going on an adventure with the PBB crew!! KUTGW 😅
Hope you all have a Happy Blessed Christmas & a Healthy New Year🙏🏻🎄❤️🥰🧸🎊
I would never use spray foam insulation. Regardless of how well it insulates. My choice would be Rockwool or a similar product.
SAME
The majority of the carbon intensity in concrete comes from when the limestone or other materials are heated at the quarry to make cement. The cement in the concrete is therefore what makes up the most of the carbon emissions. That’s why a lot of places are trying to use supplementary or SCMS to substitute as much cement as possible while still maintaining its structural capabilities.
I always recommend find your contractor first and designing your home with him and the architect. Going directly to an architect can be expensive and the plans always have to b revised once the builder gets them and makes changes
I agree
Happy Birthday, Eric Hoping you have a great day
Building a healthy home is very dependent on your climate...the vapor barrier placement moves in the wall assembly, compared to your rainfall, temperatures, etc.
Very informative video, but my favorite part was when Erik mentioned “liquid water” 😂
Water can be in 3 phases… solid, liquid and gas… what is funny about only discussing one of these phases😢
@@Aidan-tu4un it's funny because each of those phases has it's own name
@@Aidan-tu4unmost know what he meant, it was just funny the way it was said
You guys... so funny! I like the mural behind you.
Well in the Netherlands energy used to be affordable.
Then Putin started a war and prices skyrocketed.
So we import a lot of LNG from the US.
Prices are coming down slowly and now the government raised taxes.
From all of Europe we pay the highest taxes on gas
Luckily we've had mild winters the last 2 years. 🙂
If Jaime reads all
Comments then hello Jaime I love all your videos especially the ones Jaime reads the comments on!! lol
Let Jaime read!!
I’ve read several accounts of improperly installed spray foam insulation destroying homes, either causing dry rot issues, or ruining the air quality from off-gassing.
Happy Birthday Erick 🎉 turned the big 50 on the 6th myself.
Happy Birthday Eric and hope you had a great day. Enjoyed this as very interesting information. Humidity causes mold and some houses have been built where this has occurred. If a window has been properly caulked around the outside with good product why would you need to spray it with water. Installation is key I would think.
Happy Birthday and the best for the good work you all do ....gr from Holland (the Netherlands)
Happy birthday Eric. Much love hope you have a great day brother.
Pressurized water, we used a water extinguisher that I had on a few jobsites. You can fill the extinguisher up with water and pressurize it with an air compressor for the life of the can.
Here in Sweden it's very much standard to be selling the excess power your solar generates to the city. It's completely automatic. Which is a good idea since storing electricity season to season isn't really realistic - at least it's not as cost efficient as selling the excess.
We watch you everyday. We get a lot of information about building from all you guys😊 I hope your holidays are filled with Joy 💓
lol at Ross Trethway. i'm like "isn't that Richard Threthewey's son, from This Old House?"
So rare & wonderful to find someone who can use what u have on hand to accomplish your goals...😅
Jason's che klist contribution was lit. Well done big bro.
Great you take the whole team there…!
Thanks guys. Your stuff if always fun and informative. Always enjoyable..
Merry Christmas 🎅 🎄 hope all the crew has an awesome one 👍🇦🇺
Architect is the writer. Builder is the editor😉
Architects the writer, engineers/consulants are the editors, contractors are the publishers.
@7:20 about roof penetrations, the last time I referenced the plumbing and building codes, they require 1 open air penetration per system, and all other vent stacks can tie back into the system and get to fresh air by that 1 penetration. (Or, if allowed in your local area, some plumbers install an admittance valve)
The limestone cycle: To make cementous materyal, superheated limestone (old coral reefs) is split into quicklime and CO2. The CO2 goes into the atmosphere as greenhouse gas. The quicklime goes to slaked lime, then lime water, then back to calcium carbonate as cement, where CO2 is re-sequestered.
Happy Happiest Birthday Eric, hope you have a great day 👏🏻👏🏻🎂🎈🎁🎉😍🍰
