Is There Waterproof Spray Foam Insulation?

[@TheIdeaLounge]

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 KZbin pertaining to this subject. Excellent video.

[@SprayJones]

Glad it was helpful!

[@2006gtobob]

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.

[@scruffy6151]

I like the fact you are making better videos on the property of each foam. 👍👍

[@SprayJones]

Thanks Scruffy. Watch for my thermal bridging video coming soon!

[@jtr82369]

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.

[@SprayJones]

You better stay tuned. We have videos on both those subjects coming out. Answers may surprise you.

[@SinnisjInsulator]

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.

[@SprayJones]

Thank you. The rise of open cell foam is for the exact reasons you have given. The speed at which the industry could grow and set up new installers.

[@mikelayman5972]

What to use for under a bus rv

[@SprayJones]

Closed cell SPF of course.

[@Andrico77]

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 ..?

[@SprayJones]

I don't have an experience with those products. Go watch the 3 tiers of SPF video and follow my guidelines to vett things out.

[@mrgylex123]

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)

[@SprayJones]

Yes, you got that right.

[@Mitalayeka]

This gets right to the point, thank u Spray Jones.

[@SprayJones]

You bet.

[@safffff1000]

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?

[@brotherheed00]

Noticed the fungal rating which I liked. Am sure you have a video on that too.

[@SprayJones]

Not yet. One day...

[@richardmccombs617]

You speak of secondary coating to seal the closed cell in wet environments. What is this secondary coating?

[@SprayJones]

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.

[@darbabowers8054]

Excellent information! Thank you.

[@SprayJones]

Glad it was helpful!

[@mrsoccergod5001]

Can you give us the cost breakdown for closed cell. I think thats pretty important as to what factors increase or decrease the price of installation

[@SprayJones]

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...

[@ruthalexander6681]

More great info!! Thanks, Mike!

[@SprayJones]

Glad it was helpful!

[@organicvids]

What if roof leaks? What if wall barrier fails?

[@morgangreek3862]

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?

[@SprayJones]

What happens when everything else is wet? Closed cell foam holds back a lot of water.

[@DF-tz3ix]

Great and useful video. Thank you.

[@SprayJones]

You are welcome!

[@jaysousa8319]

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

[@SprayJones]

All spray foam. No panels. Going to be doing a container home video soon. Perfect fit of the insulation it what matters most.

[@jaysousa8319]

Thanks and look forward to the container episode.

[@PerfectExsneeder]

What is "poly"?

[@njsongwriter]

Can I buy closed cell foam in a can?

[@jasonyork1435]

So what about doing this outdoors in a humid part of the world? Like under houses on piers on Australia's coast??

[@SprayJones]

Sure. Vancouver, B.C. has a wet and warm climate. Peru has used SPF in buildings for scientific research stations.

[@currentliveoccupant]

In a Humid Tropical climate would it be a problem to closed cell foam each side of a cement/CMU wall? Or Roof/Ceiling(Roof would also be the celling)

[@SprayJones]

With the limited info you gave I cannot see why this would be an issue.

[@AnthonyBrusca]

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.

[@SprayJones]

There is no issue spraying to that system. It is not much different than a commercial grade EFFSI wall and SPF.

[@barbaramatthews4735]

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?

[@SprayJones]

IT could be a 2lb foam or higher if they want the unit to be more firm.

[@dekebell3307]

Thank you!

[@singtracks]

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

[@SprayJones]

I am not a roofer. You need to choose a supplier and tech rep who will answer those questions for you.

[@FJB2020]

That garage looks very familiar....

[@like5705]

Thanks for the information.

[@SprayJones]

Our pleasure!

[@smuhhhh]

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.

[@SprayJones]

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.

[@johnwhite2576]

WHY NOT JUST USE POLYISO ON EXTERIOR FOUNDATION WALL ??

[@SprayJones]

I am not sure of what you are saying...... why not eat more beef?

[@jerryf609]

@@SprayJones i get a chuckle out if your comments like this. You sir are a straight shooter.

[@CanadianParamedic]

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" - kzbin.info/www/bejne/fGKTi3edlKxsbqM

[@SprayJones]

So so typical. There are 4 things needed to make good SPF: heat & mix & heat & mix. DIY has none of these.
