you got more than one fan. I just started spraying myself, im not very good. dont have anyone to show me, just teaching my self by watching your videos.
Regarding your “generational home” comment, I’m just learning about spray foam and came upon the concept of “thermal drift” where the structure of spray foam degrades, supposedly up to 10% over time. Most info on this is behind paywalls, so I can’t find useful info. I’m more concerned about structural impacts (foam pulling away from backers) than potential degradation of R-value from R20 to R18. In short: what will closed cell spray foam look like 10 years after installation? 20 years? 30 years?
LTTR is Long term thermal resistance. It is rated to 30 years. The certification, testing and ASTM / UL tests are industry standards for testing of products. So how can we be required to test to the highest standards in the industry only to claim that the product will degrade or lose vapor barrier characteristics or adhesion when it passed the tests to look for those exact qualities...? Why is the foam listed in the building code? Why do engineers specify it? Why has it already been studied and used for 45 plus years? Ignorant speech sounds important until someone who knows what they are talking about shouts down the liars.
@@SprayJones not sure I’d use the term “liar”, they may be as ignorant as I am and assuming way too much. Which is why I’m seeking to be better informed. Thanks for your reply. I have also heard that this affects the foam base used for stucco, causing failed stucco over time, this also seems overblown.
Mike...I am fairly new to the business but when I spray...seems like foam splats go everywhere...watching you do it...well ,let's just say that.....your way neater...experience?your foam?temp?pressure?...thanks Lee
Good foam is essential. Pressure has to be turned down, temperature is vital: must be Goldilocks. Stay patient. You are watching guys with 7 & 9 years experience spray our foam. Give it a year, keep playing with settings to find the sweet spots.
Having watched a few of your vids, I notice it's so far just wooden structures. Is foam in hollow bricks something you'd say is ok? I've just used some canister, not spraygun, but I'll expand next year with lots of bricks, and insulate with foam (think it's 0.5 lb, which I just learned from the previous vid of yours I just watched). I dig your vids btw, started with the 40+ mins on foam, where I found the link to this vid. Subbed
@@SprayJones Yes, that's it! Didn't know (or recall) what it was called in English. Thanks for clarifying, and for that matter already uploading something relevant to my question.
Just wondering did this house have 2x4 “ outside walls? If so was this because of the use of spray foam? What is the average costs comparison between spray and bat insulation on a complete home? I do agree that the building code should require a leak test for every home built, people will argue the cost but over 20-30 yrs how much fuel is used and how many green house gases are created? If people want to lower green house gases then start with insulation and the building code not high efficient furnaces! Once again great video just need to pan a little slower when videoing! P.S. You may of saw this, it was on CTV news regarding a extremely poor spray foam job in Bears paw, Calgary .calgary.ctvnews.ca/video?clipId=2046367
Why doesn't the house have housewrap? I would think housewrap should be before windows and insulation. If you are paying for excellent insulation you don't want rotted walls from crappy window installs and no house wrap...
Relax have a Zanyx. They will wrap the house before stucco. Timing sometimes means the builder won't wait weeks if the stucco trade is held up, so we come in.

You have more than one fan here in NC!
Another
Great video. Very informative thanks for citing all three very different examples/scenarios
Glad it was helpful!
Im your a big fan also. Now im working also here in qatar as machine operator. And sprayman of foam i'll getting sime ideas on your video
Wow. Thanks for that word. You are a long ways away from where I am.
Do you do many double studded walls where there is a space between the studs to stop bridging?
Very minimal. It is not worth the added costs and time.
Man you do a great job , other company’s should use you as a example of how to do there work , also you have another fan
I appreciate that!

I am not following on the hollow brick thing.... like cinder blocks? I have a video just on old brick structures to watch...

What was the blower door score?
Was that blue stuff spray-caulk?
I like the sealing bonus of that but wouldn't it be a pain to drywall over and cause uneven surfaces?
No. Compressable by 80%
@@SprayJones Oh wow that's cool. What's it called?
@@aaronsvoboda5897 Eco Seal
@@SprayJones Sweet thanks for the info! Gotta admit, your videos are pretty cool & super informative :)
@@SprayJones I find that eco seal isn't being used much anymore, I wonder why since it's such a good concept.

2"x 6" framing.
Thanks for passing along the video. I had no seen it. Wow! That is the worst spray job I have ever seen.
What is the cost difference between spray foam compared to fiberglass insulation?
X2 or x3 more than batts
can modular homes be done you know glorified mobiles
Yes. If they are gutted or open.
The music is gone? What happened?
I thought we'd try something clean for a while. Had nay sayers o the music early all the time.
