In 2006 I had my newly constructed house closed cell spray foamed from sill to attic peak . I have found that the strength of the monolithic shell is one of the best things about the product. Sound deadening is another i live on hill with many high wind days. Very reassuring

I've been trying to say this for years to building inspectors, etc. They will not adjust their thinking until it says something about this subject in the Provencal or national code. You have a good way of saying it. Thanks

There is probably nothing more frustrating than talking with officials about insulation R values and the difference with Spray Foam. The question I ask them- If you are stranded at-30 and had a choice to wrap your body in fibreglass batts or step into a Styrofoam box to survive which wold you choose?

I do insulation. And I won't even rep poly jobs. I won't do it. If a customer can't afford things. I'll suggest a batt hybrid situation. But that's it! No poly. And I'm trying my best to hot roof any situation that anyone allows us to. We dont use horse hair anymore for a reason!! We have foam. Let's foam!

Great info. Love the real-world application for the technical data 💪🏼

Pinal County in Arizona has allowed "Prescriptive performance" that exceeds 2018 IRC codes for R-Value and Prescriptive performance. If I remember in my conversation w/ the spray foam company that got this implemented 5 1/2" of open cell will met the R38 roof requirement.

But you going to sell that? Look at beautiful black (ugly) cabinets, granite (cheap as possible) countertops, tile floors (badly installed in most cases by cheap labor) and so on and on. Now, show me insulation in the wall and who will care about that if client don't see it?

One of the persons I worked with that was well versed in construction said fiberous insulation is an air filter, foam is an air blocker. When you think about it that way, you understand things differently.

What method did you use? I have an old house built 47 and was well designed for wood heat in most rooms of a 2 story house, but insulation was not installed.

No one explains spray foam better; well done!

Thank you for the video. It was very informative. I have batt insulation in my two homes. I've thought about a spray foam done in the one home to see how it goes. But I have heard a house can't be sold with foam insulation installed and that it has to be removed before being able to close on the sale. I've also heard of wood rotting because of moisture being trapped. With foam insulation wiring can't be added. IS this true? Can you address these issues that I've been told about maybe in a future video. There are so many things that I hear about it. Lastly, can it be sprayed in a wall where batt insulation has already been installed or does the drywall have to be removed and the insulation removed? Thanks for any information.

Thanks for the video. As a homeowner I would love to hear you address the concern about putting spray foam in a very old more than 100 years house. Online they say that you will end up with water problems if you use spray foam

It will absolutely cause issues if you don't address the rest of the building envelope. Think about it... Your building made it this long because it can easily dry out. If you seal it up the wrong way then it will rot in no time.

Can you apply spray foam over a radiant barrier on a gramble roof/ceiling.

I normally do renovations in the winter and when its -20 you will see in the walls where all the air leaks are And the frozen batts of pink in there i have been spray foaming my apts for 12 years and would never use any other product

Closed cell foam is so good on so many levels. I have seen so many poorly installed fiberglass insulation jobs, it’s always a battle. Splitting wires, cutting around boxes, tight fit stud to stud, this is almost always something that is missed

Framing looks amazing.

Hey Mike! It’s so great to have you share your experience here! I want to start by saying that I’m just beginning to learn about foam, so please excuse my ignorance. I’m in Dallas, TX and looking to spray my new home with open cell. I saw a Matt Risinger video about open cell being a bit more flammable than other insulations and it scared me a bit… he advertised a fire resistant coating that can be sprayed on top of the open cell. Do you have any experience with that kind of spray product? Any thoughts on open cell being flammable?

Watch the playlist I have just dedicated to open cell. Some more info is there.

I'm down in Central Texas. I'm considering a project where the walls will be built from 2'x2'x4' concrete blocks. It will be easier to spray foam the insides of the walls, and use the exterior face of the blocks as the finished surface (no extra money for siding). Assuming I furr out the interior walls to hold drywall, shiplap, etc..., how important do you think it is to have a thermal break between the concrete and the furring strips? Something like 1" pink board between the strips and the concrete.

My problem with spray foam is you have domestic companies importing Chinese chemicals/foams that aren’t actually tested in Canada, and we are taking their word for it when it comes to efficacy and safety; China is known to lie about nearly everything. I only trust big names like BASF. The other problem is that it’s so expensive. There needs to be some sort of government rebates or something to bring down the cost to make it comparable with that fibreglass garbage.

@SprayJones

In Canada anyone with a foam going into houses or commercial has to pass CCMC certification of all the 3rd party testing. I am not sure China companies can do that. I agree on the rebate idea. Talk with conservative party leaders.

Cheaper foam would help. 12 years ago the foam was drastically cheaper then compared to now and people had the same thoughts. "Oh it's too expensive". It is a mindset issue. No one expects hardwoods to be closer in price to carpet or lino, so why do we expect rigid insulations to be in the league of non-skilled batts.

A fire rating is only evaluated in assembly. Why isn't the thermal envelope?

@SprayJones

They have done that, It is called the wall energy rating. When it was done fibrous came out looking disastrously. There are people who do not want things to change for the better.

If you can get it done then get the price lower, this is the reason people are still using fiberglass, we all know the theory of foam being better , it's the price pure n simple

12 years ago the price was much lower than it is today. Back then your types said the same thing. For some the issue is between their ears.

R-Value is still very important. But good insulation needs to have resistance for heat AND air/vapor. Spray foam is not the only solution for this. Smart framing, good WRB, exterior insulation, and a properly installed air barrier are all critical components of a modern building (and should be in building code). Combining those methods with blown-in insulation or PROPERLY installed batts will be fine.

I had my metal pole barn/wood shop insulted with closed cell foam and am very happy with it. Just now the KZread algorithm popped up a counter/anti spray foam video "Spray Foam Bummers: Make Informed Decisions.... " kzread.info/dash/bejne/lpemuq58o7PQqps.html You (Spray Jones) have rebutted most of the "cons" but I am wondering about the claim of fire retardants in the foam that would come out of the foam (before I insulate my next house with foam) Thanks

@SprayJones

7 ай бұрын

I am going down that list claim by claim. I will get to the fire retardants soon enough because I want the facts to be thorough. For now I can tell you to proceed and there is no issues with USA made products.

Okay, I think I have binged on all of your videos over the last couple of days or most anyway. Take what I am saying as my thoughts, not perfect but as a builder and current inspector with experience, I do have opinions. I am not against the principles and concept in reality they are Joseph Lstiburek founding principles of Building Science. Many I have noticed have tried to adopt them without due credit. Thats okay, I am not the thought police. If you have been in his classes, you know Joe is not short on words or always politically correct…LOL. Like I mentioned I think the foam insulation is overall beneficial if done right. I also think that it is very expensive when compared to other options. I know that it will probably outperform other options, but it still comes down to money. A new Corvette will outperform a Toyota but not all can afford a Corvette. At least with traditional insulation a homeowner can do it themselves to save big money on labor, not so with spray foam. I have not looked into it but I am sure the lobbyist have demanded licenses just to get the product in raw form and the equipment will be expensive as well, not DIY friendly. Good for the installers. I think purposely its pricing has been pushed to similarly compare to other insulation options. Not because it cost more to produce but using all the "benefits" to support the extra costs. So do I think some over costs are happening at the supplier/manufacturer and the installer, yes of course. If you build a perfect home no one can afford it. Well, most folks anyway. You’re making the case for the product, and I understand it, that is your business. I do think you should share the drawbacks; nothing is perfect, and this product will come to pass as something else comes along even better. Remember when they thought aluminum wiring and Federal Pacific Panels were so great? The major drawback I see at this time is inflated costs, and eventual roof repair. Roofs do not last forever, and eventually the sheathing will need replacement in some areas when shingles (most roofs are composite or fiberglass for the same reasons, costs) are replaced. It is very easy to replace on a typical vented roof but not so much on a spray-foam now conditioned attic. Of course, it can be done but it will cost more. Any future renovations, gaining access to wires/plumbing will be more difficult as well. How does arching wires in a wall or ceiling assembly react with the product? So, if a new home buyer has a choice of conventional insulation and spray foam the cost, I guess will be quite a bit more as even the builder will try and get in on the act… Now if the cost of spray foam insulation and conventional are similar then it is a no brainer. There is less labor involved and is quite a bit faster so it should be less expensive, but I do not think it is. Again, I think it can be a great upgrade to our current homes and new builds but as always, we may need to let the new thing wear off as prices stabilize like all new things that come out very expensive than the price decreases due to market. Thanks again for your hard work on the videos. I know you cannot be unbiased as it is your business and you need to sell it, kind of like me recommending a home inspection…LOL. Thanks again. I forgot, I could recommend this to a client if they could afford it, and if they are replacing their roof, preferably metal roof properly installed, and all renovations are done.
