My daughter is doing an addition and a remodel in Libery, Maine. Her designer/contractor is using Polyiso spray foam in the new structures. She has had mold and chemical respiratory sensitivities since moving to Maine. She is very concerned about polyiso spray foam after reading about Vermont spray foam nightmares. Therefore: Is there long term out-gasing due to large temperature changes? Is there a significant R value loss or gas release due to shrinkage? Thanks, Sam
Nearly all spray foams in the USA have a 24 zero VOC rating. I suggest that you watch my fire health and safety playlist and view the videos that ask questions you have. There are ones there for VOC and off gassing.
What is your opinion of reusing the blown fiberglass in an attic. I’m going to have it vacuumed out then have the attic sprayfoamed to the proper insulating level. Is there any negative of having them put that blown fiberglass back on top. I understand why flash and batt is a bad idea in a wall because of space constraints. But there is not the same space issue in my attic.
Question regarding spraying on the exterior. I'm looking at some shipping container construction in zone 5/6. I was hoping to insulate the exterior with R60 but it looks like you can't get that with spray foam since it's limited to 5-6" total thickness. Though all the info I'm seeing is from over a decade ago. Is that still the case? Just wondering if I can get this done using a spray foam on the exterior or if I gotta seek other means.
You need some help. Why are you spraying R60 in the first place? Go watch my vid on "how much foam do I need" Second get speaking with a knowledgeable SPF company in your area to walk you through how much and what it'll cost. Yes foam can go to the outside. Just prepare to cover the foam and all that will entail.
Impossible to answer. Too many variables to factor into the price: travel, thickness, type of foam, time of year, access at site, hard to get details, extra prep or clean up.. etc etc.
Excellent video. And what you said about the U.S. standards lagging behind Canada is so true. It is such a joke here In the U.S.. I have a friend who work in the southwest portion of his state and between the 3 states that border each other which has 7 or 8 counties the construction regulations all differ to some degree. And sometimes each city has different regulations as well.
Your chanel is better then even manufacturers
Lol that's not hard to do. Too many lawyers for them.
Thanks
Excellent video! Expansion is key!
Great overview thank you. I will definitely review this right before I call the contractors.
Glad it was helpful!
Excellent foam application, very satisfying to watch.
Thank you very much!
You have not spoken about open cell spray -.when would u use it? And isn’t it less toxic because the expansion agent is water and water-based?
Another super informative video!! Thanks, Mike!!
Glad you liked it!

Can you do one on "Foam-it-green" DIY foam kits?
Go watch my already made videos on DIY foam on the channel

I dislike fibrous of all kinds. So anytime I can get rid of it do so.

Do you purchase your spray rigs already built or do you outfit the trailers yourself?
Both
Whats A fair price per sq ft for spray foam install? Wanna make sure I don't get screwed by contractor
