@@powerof9915 You don't know what your talking about. All plywood is glued together with the same isocyanates used in the A material in spray foam. To ban foam you'd literally have to ban plywood . Spray foam is designed to be completely neutralized and inert after it is set up. In a closed cell format the foams in the cells of the foam are little vacuums and they are not releasing O-VOC they're they're airtight little bubbles, a vacuum bubble, and that it's actually drawing the chemicals inward not expelling the pieces outward. Now the first initial part of the test lasts for 24 hours and that's why the Toxicologists state a reoccupancy at 24 hours. Because the initial test is done and that they are not detecting any vocs within a 24 hour period hence they set the reoccupancy at 24 hours. Now reoccupancy is you coming back into your house to live in. re-entry into a house is RATED at just an HOUR. Within the first hour they can't detect the iso, nor the catalysts, nor the fire retardants. The toxicologists said the data is clear, we can see that it's not anywhere near harmful levels at all and that it's it's nearly zero after just an hour of it being sprayed.
"Isocyanates are commonly used as adhesives in the manufacturing of composite wood products such as Oriented Strand Board (OSB), Medium Density Fiberboard (MDF), and Laminated Veneer Lumber (LVL). These adhesives provide strong, durable bonds that are essential for the structural integrity of these wood products"
Spray foam off gasses the first 24 hours. Not good for your health during that time.. after that as long as properly done there are no concerns or evidence of problem. basically there are a lot of other initiatives in the industry that would like for spray foam to go away

Josh, you said 1" closed cell on steel, then open cell (probably filling cavity ?) on House section? Also is your plan 1" or 2" closed cell in Shop section only?
@@ronaldteselle4530 yes that’s the plan except we also spray the roof again to a desired R-Factor with open cell too. The closed cell is just to create a thermal break
Great rundown of the fear mongering that happened in the UK with foam stupidly applied to very old houses that need to breath to prevent rot. This doesn't apply to a new construction houses. It especially doesn't apply to a barndo designed like a Texas Best with a 26 Ga metal panel and Zip. Nothing comes close to closed cell sealing up metal panel.

Wpuld love ypur opinion on the healthbadpects pf spray foam, I was disapppointed hearing it may not be good
It will be outlawed within 10 years

I’m always hearing the same thing.

I like the color.
Thanks Tim!
Great update and explanation about spray foam. Having a great spray foam Installer is important, too. This is not an area where one could cut corners.
Great point! Thank you guys!
Lots of good information in this video!
Sweet! Glad you enjoyed it.

That’s a great point about the commonality of isocyanates in building materials! Thank you!
Josh as soon as the house sells we will be calling to see what we can do..I hope Emory is close enough❤
Ok then! 🤩

If you could only afford one what would you recommend: 1.) Spray foam sprayed on the metal panels (no ZIP) or 2.) ZIP with fiberglass batts?
@@dgerfan8475 zip roof with open cell foam how I would prefer it.

Yes, you are correct! Thank you!
I have heard that some insurance companies are not wanting to insure homes that have spray foam insulation in them. What has your experience been?
Josh addresses this in the video.
Yes we covered that in this video. Thank you
