Once again, thank you so much for your clear, precise, and concise presentation with the actual facts and figures. I really wish I knew more about all this 6.5 years ago when my wife and I bought a home in Az, sucked out the 1.5-2" of shoddy attic "insulation" (in an 8yr old home, obviously the inspectors didn't inspect anything up there and the insulation subcontractor cut corners) and replaced it with 18" of the same for 5g...and it needs to be done AGAIN. Az gets windy and DUSTY. That stuff has been blown all over up there, rendering large portions of my attic effectively uninsulated but for the drywall.
Thank you for being so detailed in your description of how foam works! This video was far more helpful than anything I've found on RU-vid pertaining to this subject. Excellent video.
if true waterproofing is required then Polyurea is the right fit for that use case. That's the industry standard for remediating water storage tanks and other containment vessels. BASF has some great polyurea solutions under the Elastocoat brand (amongst others)
Depending on my money situation, I plan to do 2" closed cell and fill in the remaining cavity with open cell in the walls and ceiling and then 2-4" on the under side for a container home. Though if I am able to completely fill with closed cell, I will do that.
Closed cell all the way, lol. But it is harder to install, much more technique required to install it. Open cell is open trigger, loved installing it vs closed cell, less neck aches in garages, lol. Your installer has great technique.
AT 1:00 in video you show a wall with lots of wall noggins, could reduce that by 3/4 or eliminate them and just have the foam for holding the studs from moving?
Odd craft question...there are a lot of people using spray foam in arts and crafts. Specifically speaking it is used to make a maniqine or dress form. In essence its a human body double. (Torso mostly) In turn the maniqine is often used for sewing and costume making. A cast is made with plastic wrap and duct tape. (Crafters think outside the box..inside the box and then use the box to make a new box.) Once the cast is made it is removed from ymthe human by cutting it off and re tapping and filling in areas to prevent the foam from escapinfmg. Foam does not come in direct contact witgmh people. The foam is sorayed in the casing material. The taped plastic wrap surpringly holds the sape of the model. The foam is used to give the duct tape cast a firm filling and will cause it to kee its shape over time. The tape cast can be remove or left in place. The foam is there and can be pinned with sewing pins and will help make clothing. Sometimes others use the maniqine for props and whatever. What type of foam do you recommend for this use? What type would be best for painting or other paint or other finishing? Does it come in colors?
A polyurethane pot mix that is spray applied. There are too many specifics to list as options. This is a highly specialized commercial / industrial coating.
Well I could but what would you have? I am Canadian, what currency? Is travel to a job site factored? Complexity of design? So what I am saying is that numbers given will vary heavily and then will be every changing. So there is no point...
Hi there, My contractor is going to use a product by Carlisle called SealTite. Any experience using that product .. thoughts. I ask because seems you typically refence BASF products, after receiving maney quotes I'm also learning there are many other products out there. Wondering if there are inferior products our there ..?
Mike, great information. Quick question. I’m looking to insulate a shipping container roof. Based on your info I’m planning on 2” of closed cell on the roof, then two layers of foam board then enclose with a shed roof. Would you recommend the foam board on the container then foam or spray foam then board? Thank you
How about flooding? If you have a coastal off grade frame home gutted. And you spray closed cell foam in a complete continuous envelope, are you protected from tidal surge? I understand the structural mechanics have to be in place. But from a water permeation perspective, are you safe from water intrusion?
Is it advisable to use a sheathing with bonded polyisocyanurate like ZIP-R and to spray closed cell polyurethane foam to it in the cavities? Will the spray foam have negative effects on the polyiso? I believe both are vapor-impermeable.
im an absolute newbie tho ive been airless paint spraying for 30 yrs ..only just ordering my reactor...are there different grades of closed cell or is it closed cell and that's it..i will mainly be looking to fix leaking roofs. does it have to be sealed with silicon or will a acrylic based masonry paint do the same thing..I'm in the uk..any help is much appreciated including a uk supplier
I'm a big fan of spray foam but I have to wonder how many decades it will be before we figure out that filling houses full of chemicals was a bad idea.
Right now. SPF has been around for 50 years in Canada / USA. The building code is written for it and has 3rd party testing. We are the most extensively tested insulation product on the market. Worry about, glues, paints, stains, etc that have NO mandated off gas testing or standards to certify against.
Thanks for all the great content. I'm interested in your comments on this. Maybe a future video. 👍 Froth pack fail on "The Build Show" - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-F10ZDg_G98A.html
