From Wisconsin here, and the thing is, if your basement is sealed well, Radon isn't an issue. And when people talk about how tightly sealed new homes are, they are forgetting you can always adjust how much air exchange you can install, and not have any significant extra costs of healing or cooling.

He explained that he has other ways to allow the house to breath besides allowing your house to accidentally leak from random unknown places. He's right too, most of the homes that leak through the walls grow mold on the back of drywall in the summer when the air conditioning is on. Some people think their exterior soffits should share and circulate air with their interior attic space- that's another terrible idea.

[@Rick-the-Swift]

@@travismiller5548 Radon testing and treatment is mostly a scam pushed by greedy fear mongers. Slabs and crawls are easily sealed to prevent any radon accumulation. Only the cheapest homes with rickety floors over bare dirt will have a chance at having any problems, and likely not even then as the house will usually be so drafty radon won't accumulate any more than it would out on the porch.

This is probably the most important aspect of this product. Also it might be beneficial to have a product that can put a thicker coat over the obvious areas where the AeroBarrier is visibly "built-up" after the initial spraying, that could prevent any separation of a super thin coating from the base material that would just allow a leak to develop.

We did this on our home in AZ (built in 1965). It paid for itself in less than 4 years! It wasn't mentioned in the video, but this can also get into your duct work and and seal any leaks there too! Our AC would be on all day and night and never get to temp in the summer, apparently we we're just cooling the inside of our walls and crawl space LOL! Now, it's only needed for a few hours a day. This is one of the best things we did for our house. HVAC will last longer, cuts down on gas/electricity, etc.

Um...$4,000/48 = 83. Your heating/cooling bills went down $83/mo after doing just this?

[@mjbates]

@@TheBighatter I don't know where you got $4000 from. Our house is roughly 2500sqft and it cost us right around $2000 to do. Spring and fall are pretty cheap, but summer months were up over $500/month and winter months were $350-450. Those months were roughly halved in cost. It really only took 3 summers to recoup the cost.

[@TheBighatter]

@@mjbates I heard $1-1.50/sqft in the video for a 3,000 sqft house. Apparently you paid quite a bit less per sqft so that changes the math substantially. But assuming 4 mo/yr of heating and 4 mo/yr of cooling, and taking for granted your statement that these month's rates were cut in half (saving of $225 avg for those 8 mo/yr) you would have made payoff in just over 1 year. Are you sure your numbers are correct?

[@ChrisWill]

That sounds like a good application for this sort of thing. I used to work in a business that would measure the "leakiness" of ductwork and we would manually apply Mastic and tape to seal ductwork.

[@matthewsorenson46]

​@TheBighatter in AZ it's a pretty common practice to do this just to the ac ductwork and it does drop the power bill significantly because so many builders out here do shoddy work. On a house built in '65 I'm willing to bet there were a fair number of previous homeowners that did some no-so-smart things to the ductwork as well

[@ohquinnok]

“The amount of dimensional change is estimated at 1 percent of the width or thickness of lumber for every 5 percent change in moisture content.” Quote from Canadian Wood Council. The allowable moisture content is 19%. Over seasonal time you can expect this will settle at 8%. So if you seal the building envelope during construction, would you anticipate leakage after a 2% shrinkage of lumber?

But in this situation of a new construction, tightening up the entire envelope to this extent is truly amazing. There is NO builder who would be able to manually tighten a home like this by caulking/foaming etc. Letting physics work for you to find all the microscopic (and big) leaks just makes sense.

Cool product. I added more loose insulation to my attic with Atticat, but before I sealed all joints from the attic. I also sealed inside the house by running 3 fans, 2 bathroom and stove, then walked around with a smoke stick closed each room check the whole room by closing the door and checking at the bottom of the door. Then if the room was leaky moved into the room to check windows and other areas with the smoke sticks. Best I could do with a 1978 house. Mine is really well sealed now. My attic is vented so just needed to seal the living space.

I had this done to my new home after the sheet rock, and they were able to bring a 3 ACH 50 minimum required to a 0.6 ACH 50. This was my first self build home and was not willing to gamble meeting the 3 ACH 50 requirement so I had AeroBarrier do the work. Within a few hours they were done. After being in my home for about 3 years now, it was well worth the cost of having a near passive home. The heating and air conditioning works better and at a lower cost.

My concern would be longevity seeing as how thin it gets applied. As soon as a hole is plugged, which would be very thin at that spot, it stops being applied and doesn't keep applying to build up a decent thickness.

If it has dropped, pull out all your furniture and do a Reapplication (going by what the AreoBarrier guy was saying) ... but only if your leak pressure is down to where you are concerned ???

We just did Aerobarrier in my occupied house from 1979 one week ago as an experiment. Had to move out everything, then back in. Improved air flow by about 2 exchanges, less than was hoped for. One reason: the basement door blew shut unbeknownst and so the basement didn't get the full treatment. Also one sliding door looked closed but wasn't fully closed. Easy to make mistakes that are hard to detect until later. Now we'll dense pack all walls next and also do AeroSeal to seal up the duct system for later geothermal heat pump delivery.

Excited to hear more about existing builds since so many homes are 20, 30, 40+ years old, not up to code, massive air leakage (regardless of climate location)...this is such a huge concern of mine since we purchased a home that is about 20 yrs old. You mentioned in the between stage of resale, and just having to cover the horizontal areas...maybe a future video prepping an existing home in that in-between stage to compliment this video?

It's nice to see what is definitely a bleeding edge technology into what is a very traditional trade. And it can make old homes more palletable for people renovating thinking they'll never have a modern home in terms of weatherization and efficiency.

Just close off all the HVAC openings. But there is also a variant to spray in the ducts, to close off all leaks in the ducts.

[@kore996]

Out of curiosity...if you started at 1 and ended up at 0.1, I understand that’s a 10x improvement but since you were already at a good starting point will that 0.9 actually make a difference you can see on savings in your bills? I have a linked home and only attached to my neighbors through a shared garage (cinder block wall). Our neighbors smoke and it comes in to our garage and then in to our house, will regular spray foam be sufficient with this type of issue? Is there a specific type of spray foam I should be looking in to? We live in Canada if temp makes a difference on material recommendation. Thanks for any help that can be provided!

Atomized sealant in the air... No respirator. 🤔 That's gonna be a bad time.

[@rndmvar]

Definitely! It collects and sticks to surfaces where airflow becomes restricted. Like in the Alveoli in your lungs. Could lead to a dry, on land drowning. They really need to emphasize the danger of breathing that in, before they get regulated/banned due to some contractor huffing it while trying to fit in last minute work.

You want your house to breathe a little so you don't trap moisture and contaminants inside. If you do this add mechanical fresh air ventilation to ensure your home can breathe.

[@literaryebooks]

You mentioned that for Minnesota AeroBarrier was used after drywall but in North Texas especially since it snows there now this application would be the same.

Did you mean that it didn't use to snow in Texas? Check out the 1895, 1958 and 1960 snow storms in the Houston Chronicle. I think the 1958 happened about the beginning of spring. Yes global climate change is coming , along with poisoned water systems, nuclear war, famine, pandemics, meteor showers, fire and brimstone. Beforehand, be sure to buy a handbasket because that's all the insulation people around when it happens will have. It will be called the tribulation

As a guy building his own house you are 100% right. I have no desire to use this technology. My parents have a 1970s house that’s leaky, cheap windows, and poorly insulated YET it’s comfortable enough, reasonable electric bills, and suffering from very little rot or wear. All this crap is adding TOO much cost and going to hurt the industry as fewer and fewer people won’t be able to afford to buy homes. Good drainage, simple rain screen, and 2 foot plus eves and your house will last for years.

that's what i was thinking. They show those lines on the top plate. I'd be like lets hit it again with the caulk gun. They should add something UV active so you can hit it with a black light and then you know where to caulk with macroscopic globs

[@arkrainflood]

how about a theoretical back of the envelope ROI calculation?

[@StormyWeather93]

I was a carpenter for a while and in my experience when you seal your outside walls like this is when you get mold. That's why we just put vapor barrier i.e. Tyvek because it allows air flow while being water resistant. You're basically making the moisture in the house stop and build up in the wall instead of move out. I feel like, especially being in the south you guys have crazy humidity, you'll have issues with your bathroom walls having rot or mold at one point. That's just my experience and the knowledge of my teacher's. Also you're paying for this which is an extra cost just to stop the smallest draft. In this case if you really want something like this just pay for spray in insulation so moisture can't even get in the walls and it plugs holes too while giving R-value as well. I wouldn't do this and just put generic fiberglass in the walls. Not trying to be shitty though, everyone in the trades has different philosophy and methods. I'd like to hear an update down the road a few years.

[@georgiafan6618]

If his Zehnder fresh air system should decline or fail, a tight home would incur breathing hazards not normally encountered. Fresh air intake is a must in a tight house and air exchanges makes for a much more comfortable home. My home’s underside roof deck is foamed and I noticed a discernible change in air quality shortly after. Humidity levels rose by 15% despite my home’s leaky windows and other intrusions. Cooking vapors, dust, hair spray, bathroom air spray fresheners, candles, furniture, urethane from floors - all out gas and accumulate which adds stress on that fresh air intake and will fill the HEPA filters quickly. There is also outgassing from some spray foams. This is an informative video.

[@StormyWeather93]

@@georgiafan6618 Exactly, that's what I was always taught. The only big positive thing I can see from this is some sort of disaster like Ash clouds or biological warfare but those are few and far between along with a bunch of other issues you'd still have to face. Overall I think it seems unessesary and a big money drain. But I'm just another dick in the KZbin comments so take it with a grain of salt.

Windows have to be sealed before application because they all leak a little and it would gum up the operation of the window. Not much of exposed wiring is horizontal, so you might get some dust on top of outlet boxes and horizontal runs.

[@JohnR84]

Why not use some forms of HEPA Air Filters to clean the inside air from the residual air particles? Opening windows & doors after interior pressurization is going to exhaust high particulate air and could upset neighbouring projects & surrounding landscaping. Might this demonstrated exhaust method contravene some local codes?

[@ke6gwf]

Once they stop the sprayers, the remaining particles settle to the floor rapidly, so most stays inside the house, and anything that vents outside settles to the ground there too.

[@lordmugglestone]

I am glad you asked that question. When I buy a new/old house that is empty.
