4 Pitfalls Of Spray Foam Insulation To Avoid

[@p.s8950]

Thank you So Much for the straight fact, void of heavy metal background music or attempts at stand-up comedy. Thanks.

I have never seen such an interesting and informative tutorial on what to look for when you have property spray foam insulated and sealed. The invaluable advice contained in this video informs and empowers customers whom otherwise would be completely in the dark about this subject.

Love the content.... A simple tip foamer to foamer. When spraying under a slab on gravel substrate it always helps to flash coat a light layer 1/4 to 1/2 inch on a large area, Then let set up to walk on and then apply second coat to complete final thickness. Helps stop foam from seeping into gravel and helps keep More consistent thickness. Patients is key while applying spray foam. 👌

[@ronwalsh]

We have been in contact with a local installer, and we are going to do our attic space since our house has almost no insulation up there. We were going to go with the open cell, but after seeing this video, I need to call the guy and get a new quote with the closed cell. Thanks for providing this great video.

We are just now getting quotes from foam spray installers for under our attic roof. I have taken note of your comments and will definitely be asking them...btw, it is a 105 year old home in FL and with the heat, we need more than the blown in cellulose that is on the attic floor. Also learned that all that previous insulation is removed to make it a much cleaner attic

[@SprayJones]

Sounds great! Keeping watch the playlist "how not to be cheated" keep your foam IQ up.

[@MavericksYouTube]

Explained very well. Thanks.

[@JB-jk3ow]

What are the health concerns long term with having this in your home with off gassing? Also, if sprayed under your roof, how would you ever know if your roof is leaking? I'm deciding between foam and wool blocking for insulation.

[@SprayJones]

Go to my playlist "spray foam 101" watch more videos most of your questions are answered there.

[@edwardogorman289]

Hi guys I live in Ireland and there is a problem with using spray foam insulation ,insurance and mortgage companies will not provide any service if it is used, because they say that the structure cannot be inspected, plumbing & electrical is obscured and difficult to check. We don't have termites but we do have woodworm they are tiny but love to eat everything for the roofing to the legs on your bed! So we're using the rolls of fiberglass or cutting the preformed sheets and then fitting them by hand. Ironically I can use it for my garden shed and on my freestanding garage because they are non-residential.

[@SprayJones]

Inspection argument is stupid and ignorant. Whole steel beams in commercial building are in cased in concrete for fire protection... so how do they inspect the steel? Same principals.

[@MrKabDrivr]

In other words: correctly applied, spray foam is the best dang insulation money can buy. Period.

[@SprayJones]

Correct

Thanks a lot for the great info. It was very helpful. I have an 8x8 shed that we are converting into a small workshop and have been researching an insulation solution. I like the idea of foam over something like Rockwool bats. The problem for me is that the job is probably too small for a contractor and will have to DIY it.

[@SprayJones]

No spraying over batts! Must be a solid surface with adhesion to the substrate.

And maybe not get it done late on Friday, or any day that a holiday is the next day! Because if it’s not the owner, the worker just might slack off, which I’ve had happen on a project. Thankfully they were coming back to do another part of the house and they were able to correct all the mistakes. Plus I think you should go through and clean up all the debris yourself (nails, screws, drywall dust,sawdust, cellulose etc.) yourself, prior to them get into the house. That way you know you’re getting a good bond, because I’ve seen it being sprayed on brick dust, and cellulose and it just doesn’t stick.

[@SprayJones]

Sounds good. You have proper points.

[@knalltutemichl3473]

[@petermiddo]

I wish this spray foam was available in Australia, particularly Brisbane. We're looking at building some timein the next 5 years and I hope, by then, that Australia has become smart enough to adopt this kind of insulation. Im guessing its as good for keeping the hot out as it is in....🤣

[@SprayJones]

That's a big question. I would assume yes someone will have it. Other countries have SPF, Europe, Japan, Canada, USA, Russia so I see why not in Australia. Do some research with BASF, they are the global leader in SPF tech and can direct you to anyone using their products in Australia.

I'm been doing spray foam for 16 years I'm going to tell you what the problem is. A lot of times is lack of training,lazy people,pushy bosses. And the biggest problem is that a lot of companies don't care about quality they just want you to go to the job and get it done. Also a lot of them like to pay guys by square footage so the guys don't really care if is being sprayed correctly or if the foam is good or anything else they just want to spray a lot of foam so they can get paid a lot. Plain and Simple. #facts

[@SprayJones]

@@wlfgang That's a lie. Our foam is certified to ZERO VOC in 24 hours. It is a requirement and is a federal standard.

[@SprayJones]

@@hairband80s69 Ok, let me amplify. In the USA there is NO mandatory off gas testing for SPF. So the suppliers can use whatever products they want - good or bad. In Canada you cannot install a SPF into a building that falls under code that does not meet the standard. So the foam that is certified cannot and will not smell within 24 hours or less. In the USA you can get foam that will NOT smell, but no one is going to make that a requirement other than obvious marketing reasons. I have a video on "I don't want stinking foam" that I am going to update and improve with more info. Stay tuned.

Yes, please. I'm dealing with sprayed in electrical, plumbing, tv rg6, and cat 5. All of this in an area that should not have been filled.

[@nick3d155]

I'm actually seeing that this means spray foam may be ideal for my 2.5 car garage. Reason: rodent gaps, 2 car garage door will always be venting some air, window AC can cook the garage well, hanging furnace with a cut-through vent will help in the winter. Goal: spend more time in my garage with easier short-term climate and humidity control. Since the door is about 1/5 of the total perimeter, air exchange should still exist. There's minimal electrical along walls, mostly along roof studs instead, and no plumbing. I'm also not opposed to a 2 type solution.. like fiberglass ceiling and foam sides. Am I way off?

[@PhpGtr]

Rodents will still get into the spray foam - easily chewed. Sad but true - from experience.

[@bearlissa]

If you have termites, it will be very difficult to find them or the damage with foam.

[@carsondavis9675]

I have a question and you seem like the most knowledgeable guy. Can you completely encase the studs in spray foam? I am looking into staggered stud construction and I want a complete thermal break using closed cell. But I also plan on using zip R sheathing outside. Do you know if this is doable? Or do I have to leave some stud exposed to allow for drying.

[@SprayJones]

The technical answer is that one side of the stud should be exposed to allow for internal moisture to have a way out. I would chat with my supplier if I was doing that for you because Zip wall is not bonded to the stud. So that side in NOT 100% tight and can equalize. But would chat with the technical advisers.

[@repalmore]

What was that purple single component that was being sprayed on the cracks. I would rather put that through my sprayer than run through a couple dozen caulking tubes. For checking foam depth I made what I call a pokey thingy. Arrow shaft with an adapter pressed in so a sharpened piano wire from a hobby shop could be set it. There was a set screw so the depth of the foam would be at the adapter(piano wire would plunge full depth). Great for an installer to keep in the other hand while spraying. What foam was that purple foam? I love NCFI antimicrobial foam. It lays down like a 3 lb foam and you still get 4k+ bf out of a 1k lb kit.

The single component is Eco Seal from Knauf. You will have to get it from a dealer. We get ours from Minneapolis.

It is funny how building ideology changes and develops over time. I can only talk about the snippet that is Europe and can say: We have been there, we have done that. All this artificial styrofoam, spray foam, glas-whool, rock-whool, ... you name it. Combine it with one of these high tech fresh air systems with all the gimmics in the world and you will get a perfectly insulated home that feels like.... living in a freaking thermos bottle =) I do understand the aspect of saving energy in a not so expensive manner, but I see a huge trend over here away from these artificial materials and back to what houses originally had been made off: Wood, clay, stone. Insulation to combine to it commonly are things like wood whool that you can get both loose and in slabs, cellulose, hamp or if more effectiveness is needed, then calcium-silicate. Everything that makes sure that a building is NOT air sealed, which is what we have been told to do for years now. You would be surprised how much better you feel by just sitting and breathing in a house made of natural materials ;)

[@themindunset]

You do really nice work. Thank you for the video. One quick question. Is there any benefit (say if you're building a tiny house and you want some structural support), in using the two-pound foam first, and then using the open-cell foam over it for the sound and r-value? I know the expense would be doubled but in a small space, I might want both properties. Just thought I'd ask. Sorry, if it's a dumb question or has been answered already.

[@SprayJones]

It is not dumb, getting this question more and more so will have to do a video on it. You can... anything is possible. I always weigh the cost to benefit ratio and for open cell to have better sound properties you need 4 inches and up. So switch out to just get 2.5 inches is a waste IMO.

[@themindunset]

@@SprayJones thank you. Makes sense when you drop in that 4 inches is needed for the sound benefits. All the best.

[@christophergruenwald5054]

@@themindunset like he was saying, you can. I don’t personally like switching back and forth all the time between open and closed cell foam with my rig. Kind of a pain and there is always wasted chemical that you can’t do anything with. In a 2x6 wall I’ve done 3 inches of closed cell and then a 1.5 inch Rockwool AFB over the top for sound. I’ve had customers that have put a 2x4 fiberglass batt over the same as well for sound and additional R. In South Dakota here the majority of what you will see installed in closed cell foam. And actually on my garage roof I did closed cell with about 12 inches of open cell over the top of it for maximum R value at lower cost. And about 6 inches of closed cell in the walls.

I'm highly considering having my garage speay foamed. The only question I have would be one regarding prep work. If I'm having the inside of the roof done with closed foam would I need to put an extra decking on the inside? My concern is if I ever need to replace the plywood.

[@christophergruenwald5054]

No. If you ever need to replace any of the plywood from leaks then you are going to pry it off the foam with pry-bars and drop a new sheet in place. Using a synthetic breathable membrane over the roof instead of tar paper will help the roof dry out quickly if it ever gets damp so it won’t rot.

I don't know what that purple stuff was... however I have never, not one time, done a remodel or fix on a house that had spray foam that the foam wasn't at least 1/2 inch to a full 2 inches away from the sides of the wall studs. You can see bits and pieces where it was clearly sprayed fully into the wall studs but over time has shrunk inside the wall. I'd never use that stuff unless I could be convinced I wouldn't be re-doing it in 5 years because it shrunk in the wall. Sorry mate.

You are generalizing from a specific problem. Adhesion to the substrate is VERY important. You have described a failure but what you have NOT done is give any clues as to what went wrong and why. Instead you just ban the use of. Even space shuttle challenger got an investigation. Foam sticks, it has to, otherwise we wouldn't be allowed in the building code. Someone messed up and it is down to 3 simple things.

[@timothymcrae77]

@@SprayJones Yes, you're right to eschew generalization and I agree. Thus my statement 'unless I could be convinced I wouldn't be redoing it in five years...' That being said, 100% failure rate thus far as far as I've seen doesn't speak well for the product. Wood walls, concrete slabs, cinderblock walls they've all had huge air gaps on every job I've been to that had it used.

[@SprayJones]

@@timothymcrae77 Very well. The testing is there (Canada) for adhesion, cohesion, dimensional stability. All of those pertain to the foam staying in place. When applying surface contaminates are what most frequently will cause a failure. So it you want I have a video on basement adhesion test report, or watch "Trouble with SPF what 5 things do we test for", also have a video on structural strength added. These may help... Cheers.

Are any isocyanate free ? The auto body industry is starting to get isocyanate free primers . Many talented friends of mine had quit the industry because of isocyanate poisoning and sensitization

[@SprayJones]

Not yet. Iso sensitization always comes from being around it unprotected......and smoking.

The first pitfall of spray foam insulation is the use of spray foam insulation.

[@SprayJones]

So kick it out of your: couch, shoes, doors, helmets, dashboards, garage doors, desks, Sofa chairs, all seat cushions, coolers, fridges, freezers... This is the nice response.

[@m.j.9627]

@@SprayJones A career in spray foam insulation. I will bet the price of entry into that job is fierce.

Hello from Toronto Ontario Canada known as zone one climate. How does a spray foam contractor spray the attic if there's no drywall or vapor barrier for it to be sprayed onto the second floor ceiling? What can the homeowner do to prep ?

[@SprayJones]

Go watch my videos on vaulted roofs. I have a playlist.

[@Daniel2w3]

Is sprayfoam allowed in Los Angeles??

[@SprayJones]

I cannot say for certain since I don't have any dealings with that area for any reason. My initial guess is 98% yes. They will just be picky on what qualifies.

[@pcno2832]

I'd think it would help a lot in quakeproofing a building.

[@SprayJones]

@@pcno2832 It would.

[@davidcart28]

Just out of curiosity what is the fire ratting on the product

[@SprayJones]

Going to have to do a specific video for that. Stay tuned.
