I have talked to 8 spray foam companies near me over the years. Really all of them are more about money than knowing the science of what they are doing. Spray foam is the best insulation but we have way too many issues with installers in the US. So most of the high end guys around me still use Rockwool and tape to ensure long life. If I had an installer that was well trained I would use it but we don't.
That's too bad.
as a technical advisor from a company that manufactures SPF, your video is very accurate and very informative. Awesome.
Thanks for watching!
i have been foaming for 15 years and some of these jobs look terrible. wish i could share some of my work here. i will say that you are very correct with all of your knowlege, very informative.
Why dont you do a video of your work it would help out the people like me who don't have the knowledge.
As a building official in the us I appreciate you information!!
Great! That is why we are here, to educate.
Ditto
These reasons are why I didn't do my own foam job in my basement. Had a bunch of people tell me to just go to Menards and get the kit. If done right, amazing product, if done wrong, a nightmare. Glad I hired a professional.
Turns out this company is just 3h from me, sadly money now days is not my friend, doing my basement seam joists, based off the videos I can make a best of a annoying situation but deff be calling for a quote int he future as I'd like to get the house done once I finish the basement more
@@Refertech101 It makes a huge difference.
The prices quoted in the US are ridiculous to its spray the my attic ceiling / underside of shingles. It isn’t made of gold. It would literally take a couple hours for a professional. So I will just buy my own and do it myself. You can buy the product anywhere but I am an HVAC dealer.
@@Balticblue93 no one can seem to do anything anymore. My 11 and 15 yr daughters are welding and installing AC units.
@@halledwardb I totally agree. My wife could pass any NATE test and install, wire and charge an air conditioning system. I think it is great you taught your daughters useful skills. The trades are a great future for the next generation.
Great commentary on spray foam wrong doings. I think it’s just too much gray area to trust the installers here in FL to do it the right way. It’s a risk you can’t afford to take back if they mess up. Unfortunate that the US doesn’t have stricter standards. It’s something we have to breathe in for the life of the home. It’s gotta be done right.
You can trust ppl, you need to learn how to weed out impostors.
Thank you sir. For informative videos. everytime im watching your videos i'm learn a lot that i use in my everyday work.
Many blessings to you. That is the idea educate and assist.
2:06 On old foam, I usually use the 2lb old stuff as a base layer of a multi inch roof. If the stink gets through the 3lb cap, no big deal. Rarely do that but as long as the total inches are up to contract, it works. Have roofs like this that are 15 years old and are still in perfect condition.
Your videos a fantastic. It is very easy to see that you are very knowledgeable and care about your end product. I am a commercial roofer and builder and I enjoy the information. I watched your video the other day about a “hot roof” and venting the attic. I have tried to tell folks that for years!!
I tore apart and rebuilt a Geodasic some years ago. The customer built it himself. He lined the studs with heavy plastic, he sealed all sides of the exterior plywood with gallons of silicone and did the stud cavities as well. He had the roof so tight with no venting that it destroyed the plywood by year 3-4. It was crazy how wet and rotten it was. He should have definitely watched your videos!!
Thanks for the comment and feedback.
Great video. To many problems to track. Its also very expensive. The quote I was given was almost $40K for a 2500 square foot house. There is just no way I would spend that kind of cash on insulation.
Hi Chris, yes it costs alot. Just curious, are you going with Cellulose?
Would you rather spend it on rising high energy bills for a lifetime?
I could do your house for less than half of that Chris...probably way less. With Cellulose I can get you at least R20 in your walls and R45 on top of the flat ceilings. We'll do your Rimjoist in the basement. We can do any interior bedroom walls that you want Sound Attenuation. Air Seal and insulate any access points. And boom, you save on your bills. Whats this guy talking about?
What state?
EDIT: And NuWool Premium Cellulose lasts for 20-30 years
Then we throw in a 5 year guarantee on all work performed
I live in KY, USA and had a new metal garage sprayed yesterday. I had open cell foam sprayed and I think I'm going to like it. There is no wood at all and the garage will only be used for motorcycles, ATV and lawnmowers. The only thing I don't like is the metal studs are five feet apart and the foam finish isn't smooth. The salesman brought this to my attention beforehand, so I can't complain. The intentions were to spray the thickness of the 4 inch studs, but they actually sprayed out to make the walls meet the front of my electrical outlets. This is likely about six inches. I was surprised that you told the customers to tape the studs and put plastic up. The company did everything for me, except take the pictures of what they were doing.
Good for you.
Super appreciated your analysis and perspective on the various issues. Wish you were operating in the US. Keep up the amazing work! 👊😎
Oh ya the smell is only when you apply way too much in one pass and also that your foam is off ratio ( too much b side). so the inside of the foam may burn and it won't cure properly. Off ratio is also very dangerous when it's too much b side or the chemical with the rising agent. Thanks for the share for all these types of failures.
You are welcome. Spraying the foam too thick too quick and resulting in smell is a BS answer that has been floating around since 2014 CBC news article. It is quickly becoming urban legend.
@@SprayJones ah good to know, but it would not let the foam inside cure properly right, the cells will be overstretched. The smell would only come from off ratio issues right? So that cbc interview probably didn't mention specifically that there were probably off ratio areas as well. I mean those installers clearly didn't care.
@@SinnisjInsulator The CBC piece did not show ANY off ratio foam. For all purposes the foam "looked" fine but smelled. I am 90% sure why. Someone got caught putting catalyst into the SPF. Hence why the supplier was not held accountable ad the installer played dumb. Either way insurance will not cover you for fraud. Hence why they did not make a claim and have it removed.
Then this BS about too thick started being said in the bars around town... blah blah. I called BS the second someone brought that up. Too thick foam will crack, smoke, do a lot of funky things, but smell like fish?? No never it doesn't smell like that in raw form in the drum... but Catalyst does in raw form!!!
@@SprayJones well said, thanks for confirming off ratio is how foam can smell. I think one supplier was working on a foam that was much more environmentally friendly when it came to the catalyst it used.
I worked for Great Northern In Woodstock Ontario,the stories I could tell,good job explaining things.
Wow, thanks
They good company ?
Could you say if they provide good training to the reps for each are in southern Ontario? I’m looking for a solution in Kingston
I watched quite a few of your videos. Excellent presentations. I hired someone to spray part of my small house about 17 years ago (- they sprayed the ceiling and walls. (400 sq ft of living space) I had zero knowledge of potential problems and I never asked). The guy had been doing spray foam for many years and the job has had zero issues, but I have no idea what was sprayed on my walls other then the guy told me it will make that space structurally stronger as well. I am now going to spray my garage(under living space) and an adjacent inside hallway. I removed all of my fiberglass I could get to. My question - Is there a 'better' or 'best' brand spray foam? I am in northern Verrmont. Thank you.
Closed cell SPF is the top of the SPF world. That said, getting a solid installer is the major consideration, if that is achieved the should bring with them a top product like Demilec of NCFI.
@@SprayJones Thanks for the info.
I was a painting contractor for 30 years. We painted a new, 6000sq ft home for a builder and the homeowner said they smelled "Chemicals" three months after the house was built. They said it was because we sprayed the trim and doors. The Builder told them they could have their money back plus just to walk away. They did. Turned out they couldn't afford the house in the first place.
Yup. Common.
"People are fundamentally lazy and in a rush". 😂 You just got a new subscriber, thank you! 😂Great Video, very informative and on point.
Hey mike I spray in NorCal I love your content great knowledge your spray crew are top notch
Awesome thank you!
I had a new house roof deck sprayed with UPC 500 open cell foam. 4 months later and with AC handler in the attic, the house smells like urethane and in the mornings more like a sour smell. So I put a piece of the foam in a zip bag and put it out in the sun. the same sour smell is observed in the bag.
My conclusion is that the foam exposed to heat via the roof deck under the sun stars producing odors which then leak inside the house. This cycle seems to be constant even with the active ventilation in the attic, which defeats the purpose of the unvented attic to begin with. What a disaster. It was applied by a reputable company that has been in business for many years.
Sorry to hear that.
Open cell foam has to be mixed before and during spraying.
OC foam has a short shelf life
Properly installed OC foam will NOT give off constant odors even in high temps. I have a video on VOC tests and results. I suggested getting more info to help prepare you for next steps you may have to take.
Another major problem can occur when closed cell resin isn't sufficiently flushed when changing over to open cell product. The classic industry term is "clopen cell". It consists of oversized cells and/or crispy chemistry, but not dark crispy like iso rich foam. Can cause smell/shrinkage issues.
Another possible problem can occur from high lift closed cell (some brands advertise up to 8" lifts) application in cold environment. Can cause shrinkage (smell?) issues and can twist framing.
And yet another problem can occur if applicators are using cheap torpedo heaters instead of expensive indirect fired job site heaters. The exhaust from burning fuel contains moisture which changes the dew point of your spray environment. Can cause shrinkage and smell issues.
Most of these problems can be prevented by using an experienced foam applicator.
Thanks for sharing your experience, Jones, very informative channel!
Yes.
Exelente trabajo . Estoy aprendiendo mucho de tu canal . Gracias por el aporte .SALUDOS DESDE ARGENTINA
I see there are many things that can go wrong with spray foam in the event of a poor job it would be a nightmare to correct.
SUGGESTION: Do a video on spraying open cell foam over a layer of closed cell foam ! Also if this is done wouldn't this slow down the freon leakage from the previous layer of closed cell thus improving its insulation level a small amount?
It is on the list to be done. So watch for it.
@@SprayJones GREAT !!
Thank you very much for this information. My company just got the machine to start doing it and I’m going to be the main man. This channel is going to help me a lot.
Glad I could help
Where are you and who is your distributor?
Thanks, this was very informative! We are hiring some pros to come in and spray our new addition. I recently learned about taping the face of the studs to prevent the foam sticking. What kind of tape works best? I have seen duct tape, painters tape, packing tape. Does it matter which kind?
Cheap and easy to remove. Try packing tape.
Well done! Love learning stuff!
Glad to hear it!
People saying it’s so flammable disregarding the fact that you cap it in drywall which is an approved barrier when properly installed. Also the amount of fire hazards like synthetic furniture and flooring that’s is massively worse in a fire.
SPF is not a fire hazard, that is BS go watch us burn the foam in the health and safety playlist.
@@SprayJones completely agree, that is an incredible video! Such a great representation of it, thank you for posting it
I am actually highly sensitive and usually correct, like identifying a propane leak before anyone else notices, which can be verified. It's not completely made up, some people have a better sense of smell, just like hearing and eyesight. There are just also people who imagine things. Technically they aren't more sensitive if the smell doesn't exist, because there is nothing to sense.
I have extremely bad lungs, even low voc products cause me breathing problems.
Spray foam, put in during building won't have an impact on me since I wouldn't be able to enter until even low voc paint has cured and the area had the air cleared.
My lungs are bad enough I have a medical exemption to wearing a mask even during the pandemic, I definitely would be making sure the crew doing spray foam knows how bad my breathing is.
@@jaquigreenlees Yes if it is mixed correctly. Properly applied spray foam is inert but sometimes the mix is off and it does offgass after installing.
I have a 35 min video coming out Tuesday on VOC and SPF. Lots of data.
@@valeriy8502 Even when mixed properly there is some out-gassing, If it's low voc then as long as it can sit for 24 hours before drywall goes in even with an off mix, I would be fine.
regular, or high voc products I can't get near for a week.
@@SprayJones I had to learn a lot quickly when my lungs went south. I know enough to know what I need to watch for and how to tell if there are enough vocs in the air to be an issue. ( if I'm grabbing my ventolyn there is a severe problem )
I have 4 different puffers I use every day, 3 of them multiple times a day. one is a medication that is a one dose a day medication. My breathing gets worse I notice, it's bad enough I had to learn to pay attention to it.
Heck, Starbucks coffee causes problems for my breathing, I can't get closer than 10 metres to one.
Thank you for your help, love all the information you provide. Great information, detailed and easy for the novice or DIYer to understand.
Glad it was helpful!
Así no se esprayea
Great video thanks for posting. Can you comment on duration of smell after installation? The first 3-7 days after having closed cell foam installed an incredible stench was off gassed from the foam but resolved after. Foam appears to have proper ratio, density, cell structure and installed within parameters and recommended lift height. I've never been around spray foam before and wondering if this was expected with usual installation. Thanks
Seems slow... but I have seen circumstances that can prolong disbursement of the odors.
Talk with the SPF manufacturer...
Thank you. Solid info, well presented.
What about it being so much more flammable than other types of insulation?
Go watch the burn video I made. It is in the playlist for health and safety. Then see...
Is it true the hvac has to be different if you use spray foam? More return air?
No, you have options...
smell can be caused from spraying to heavy more than 2 inch lifts also the heat can cause smoldering and can catch fire also but it causes a fish smell
Only at the 11:00 mark did the tech spray the corners of stud and wall First. I thought it was standard proceedure to do that?
I think I will stay with rockwool and only use spray foam in small areas, maybe less than 10% .
A lot like when I got into carpet cleaning, if your not a chemist, don’t play one.
Sure.
Hahaha i have since been watching your videos! Ill watch them all before i start my first job
Good.
Sub then if you haven't
So how do you fix these problems seems to me it really adheres to everything and if it's bad sounds like you would have basically no remedy for problem
It has the potential to be messy and tiresome if it needs to be removed. But then shouldn't it be painful if you screw up? Learn your lesson.
From many videos on UA-cam the problem leaves homeowners without a house to live in while fighting a company to admit there is a problem to fix...then the lawyers and court and well you get the picture.
Thank You
You're welcome
I really want to spend a year as an apprentice trained by someone like this.
If the wood was dry but standard pressure treated will that cause delamination?
No.
Wet or oil causes issues.
Great vid.
Can you spray new foam onto cured foam? If there was a missed area or a gap, can you just spray over and fill?
Yes you can!
Do you still need a vapour barrier on those walls and ceilings where you have sprayed closed cell directly to roof and wall plywood between joists and studs?(unvented roof).
No. But watch for next week's video. I have a specific one coming for vapor barriers both Open and closed cell.
Hi Spray Jones
Have you ever seen closed cell sprayfoam delaminate from trusses in attic floor? With the wide temperature change from winter to summer and trusses being wood, I am concerned that the sprayfoam would separate from the bottom chord of the trusses.
I'm in Ottawa, 2 storey home being built.
Thanks
It will not. A CCMC certified product has to meet adhesion standards.
As long as it is installed properly you will be fine for generations.
This is great info, thanks for doing this video! I'm looking at hiring a company to spray my new shop, and I'm concerned about the health impact of the off gassing after seeing some horror stories of people getting really sick and having to go to extremes like removing their entire roof. I've tried to find a good, well priced (meaning I'm willing to pay more for quality) contractor that has excellent ratings, but that has failed me in the past. Is the off gassing issue fairly rare, especially for well-established and well rated contractors?
I have the same worries!!! Every foam company uses this excuses “that’s ur problem….u look on the internet…” it’s 2022 and I’m sure there is still bad installs
@@diaperdood1 I checked the company I ended up using out thoroughly, and they did a great job. The problem I ran into afterward was loud popping and snapping sounds. I applied it to a metal building. No one ever suggested this might happen. Doing more research, it's a common thing, and could mean separation. Probably a complete waste, and I will probably never do it again. It's quite cool inside though
@@supernat1978 how long did u stay outside before going back in
@@diaperdood1 I got covid the week they finished, so about 3 months now 😆 I haven't actually been able to spend any time in there, but have gone in for a few minutes at a time, definitely is a smell, but not super strong. And didn't cause me breathing issues. Having said that, I probably would never put this in a home.
@@supernat1978 WTF...shit!
I know codes vary depending on where you live. That said, is it a code violation to spray closed cell foam onto old BX electrical cable? I have a damp enclosed crawl space and I want to spray foam the plywood of the floor above to prevent moisture from rising into the room above. How many inches of closed cell spray foam do I need to stop moisture pentation? Which brands of spray foam do you consider the best to use in an enclosed crawl space? Should I dehumidify the space before having the foam installed?
Thank you for this excellent video. It answered a number of questions I had concerning installing spray foam insulation
Not for nothing but this channel has all these questions answered in videos. Cruise around and find them, I have wiring videos, condensation videos...
What kind of mustard do you like?
Spicy
@@SprayJones great video.
Thanks for your explanation about spraying in different temperatures. I want to get my Garage and Room above my front porch sprayed. Can they be safely sprayed at this time of the year March-April without having issues regarding the temperatures being too cold or having different temperature swings from one day to the next? Also how long does it take for the foam to completely cure?
I forgot to mention I am in Ontario Canada (East of Toronto).
You more than likely will be fine. But that is not my call it depends on the day and temps, along with system chemistry. Ontario is quite warm now.
Watch " what conditions do we need" video.
I did sales for a company and they used expired foam they bought expired, they had me selling b.a.s.f. foam, which is the best, however they installed expired off brand foam and the foam stinks and pulls back off the studs. Also the installers where so stupid and did bad work, also there truck leaked oil and they would park right in the driveway without a care. They only stay busy because they get new customers from home shows. I quit after I realized their ethics were so incredibly low.
Very common unfortunately.
Well you have idiots in every trade
Working on a bonus room and wonder If that's OK to use fiber glass insulation in between floor joists and use foam in between rafters for the rest ?
it is a very pitched roof
Great informative video. I would like to know your suggestions for areas of an attic that are above outdoor areas: car port, front and back porch. Do you spray those areas or something else? Thanks
The body of info on this channel is vast enough that if you are learning you should be able to come up with a proper idea for those areas.
I’m curious to know If you’re spraying a 2 x 6 wall do you spread the cavity completely full it’s full and then shave it off I’ve seen some people putting fiberglass insulation will see the spray 3 inches of foam which deck technically gives you an hour 21 and then they put bad insulation on top of that is that recommended desert sweat what are the problems what are the issues
very helpful information like always.
Glad it was helpful!
Excellent
Thank you! Cheers!
At 250 what is on the studs to make them so shiny and why? Great video series
Tape. No scrape
Thanks for sharing the information, I live in Grand Rapids Michigan and this summer I plan to insulate my garage and I wanted to know who do you recommend ?
I have no idea.
All boils down to, can i trust the operator. And considering how much can go wrong and the issues it can cause i would not.
Hmm, so no flying in an airliner No driving at night, no eating food you didn't prepare, medicine you didn't test, medical procedures you do yourself.... get my drift?
I’m getting close cell foam in my garage, my question is do I need to use MC cable to avoid mice from eating the wires or is there something in closed cell that will prevent mice from eating it?
Mice will not eat it. Get a cat... Lol
@@SprayJones Don’t think my 165 pound mastiff would like that too much
can you foam the roof of a pole shed, ( the outside top of the roof, not inside the building ) and coat it with a waterproof coating to keep the inside from dripping in Minnesota or will it still not stop dripping because the steel is still exposed inside?
Yes.
We don't.
You should have 3 lb roofing foam and UV stable top coat - many to choose from.
Good video thanks a lot
I live in Asia
How can we test/know if they are using open or closed cell when they spray?
We don't always get what we pay for here. It can be common to pay for one thing, and them give you a lesser product
Watch my videos on Open cell. It very different. Put the time in to educate yourself on SPF in general. Thieves flourish through ignorance.
After watching the way it can destroy a family home when not installed correctly, and the denial from the companies to fix it... it is NOT worth the risk. There are other solutions that don't risk your health hoping some guy had his head on straight and cared while playing chemist in a van.
1. Denial to do the right thing is human nature find and industry that doesn't have this
2. We don't play chemist that part is already supplied
3. The regulations allow and have allowed for SPF for 40 years in buildings
4. SPF solves more issues for people every year than it creates.
5. These things are are all open source.
@@SprayJones sorry. I didn’t mean to imply that you yourself do a poor job.
But as a consumer there is very little protection when there is a problem. You even said some people just believe they smell something when there isn’t anything there. That is the same excuse that a bad company would give when there actually is something terribly wrong... even when the smell was obvious. Not like you can argue smell in court. Causing a family to abandon their house and hire expensive outside sources to prove the problem then lawyers and courts to attempt to remedy it. While the family is left to live in a trailer on their driveway.
When a customer complains that the odor is giving them a headache but you don’t smell anything how to you test it?
Sure it’s a great product when installed correctly. But when it’s not the risk and expenses and sometimes critical health issues are all on the customer.
It’s quite the gamble.
As you stated removing it is extremely difficult especially by a company who poorly installed it and refuses to admit there’s a problem when it happens.
So a consumer could end up with great insulation, or get so poisoned the wouldn’t have the energy to fight it out and have to abandon their house.
Solve that issue, then we can talk.
Again sorry if this is your industry, as a consumer there are better and safer methods without that risk.
Good point
@@c.m.303 shittttt
I have spray foam insulation on shingled new build home.
Now 6 months in I have to replace the roof due to hail .
Can I put on a metal roof?
Does the roof need venting with spray foam? Visually my shingled roof has seam vents. I don’t know if they sprayed the foam over these vents .
What do I need to know when replacing my roof? Thank you!
I don't know about your needs. Contact your SPF installer, chat with them.
If non vented roof with SPF you can re-shingle or place metal over with out any major changes.
Just curious on what tape you use on studs & do you use a tape roller with an extension?
I was wondering if you have any videos on different spray guns and what pattern is best to use in spray foaming. I have a PMC PH-2 gun and I’m considering getting a fusion Ap. I’ve seen a lot of people using them and I’m wondering if there is a spray patter and quality difference between this two guns.
Personal preference. Most of the guns will deliver just fine. It is the foam, settings, environmental conditions and operator that sways results.
What's the blue stuff on the narrow portions of the studs?
Air seal caulking.
So i see purple and blue colored foam in this video, does adding color change the quality of the result one is trying to get as well? Why have color in it?
Trademark colours
My spray foam smells so bad. Looks cured. Turning into a nightmare. I have tried ventilation and it isn't working. Do you know how to remediate or any suggestions on remediation? Does it need to be removed? Just desperate!
Removal....
Great vid
Also, what gun do you use
Good info !
Glad it was helpful!
Where can I get trained by someone like him?
3 years later. No Off Gassing laws.
What about fire resistance
I used spray foam over my basement foundation walls. I remember hearing a popping sound come from that area after I finished. Could the spray foam have exploded and leaked liquid down onto the floor? The floor around there is all damp and sticky now. There is a foundation crack behind there that has never leaked in 50 year old home and that area outside is under the deck so I don’t think it’s leaking. I did try and fill the crack with a Sika epoxy resin and that stuff ran down onto the floor also. Thoughts?
Foam disbonded from the wall. That is the sound you heard.
Cut it out and re-spray properly. Dry!
@@SprayJones awesome thanks for the reply. How imperative is it to respray? Just by looking at it it looks okay minus the “leak”. Will there be future issues if I don’t respray it?
@@ennsy9 Then leave it. Up to you...
@@SprayJones I hacked out the stuff that was wet from the leak but left the majority. Seems to be fine. Thanks for your help.
Where can I buy this if I live in America
You hire a spray foam contractor
Can you spray over XPS (styrofoam) for the purpose of increasing R value and filling a wall cavity?
Yes, but the XPS MUST be well adhered or it will be a disaster.
Very nice
isnt the masking under the rim joist in the video at about 3:37 preventing a seal between bottom plate and top of foundation?
There would be a sill gasket in between which you likely cannot see. Wood on cement for example is not permitted. Please ignore the rude remark above.
Can that spray foam from the great stuff can also off gas?????
Catch up to Canada? Sir, please stay focused on the title of the video, thank you.
Can I used closed cell foam spray on a unvented metal roof?
Yes.
Watch the roof series. Part 3 is the one you need.
@@SprayJones Thanks! What about it being so tight that inside moisture can't escape, causing excess humidity as some say? Is this also covered in Part 3? I will watch and subscribe in that you were kind enough to answer.
@@rickblythe4864 It is covered for sure in the series. I strongly suggest taking the ride and watch videos 1-4 so you will be up to speed on the science and ways of doing it.
@@SprayJones Thanks again!
Looks good
Thank you for watching.
I'm doing siding on a new home that is getting sprayed. I showed up to half a wall soaking wet and half dry as a bone on the house wrap (tyvek). The wall inside was half sprayed 10 days prier to me showing up. The part of the wall that was dripping with condensation was sprayed the part that was bone dry was not sprayed. You could see the studs through the plywood and tyvek. Was -1 c in the morning . Any ideas why
Seeing studs in normal. That is the storage affect of the lumber mass.
I need more info to assess what you saw. Was there heat on inside the house?
Watch my video on why there are lines on the roofs of homes sprayed with SPF. You'll find it in the playlist for vaulted ceilings. Explains the phenom for you.
There was no heat in the house and was around 1c in the morning. Picture a wall on half sprayed and the other half not sprayed. The insolated part of the was soaking wet with condensation on the outside ply wood and house wrap. The part that was not sprayed was dry as a bone.
@@SprayJones
I had 2 way spray foam done in September in Ohio, weather was warm, but my garage in mid to late Oct garage is very cold. I have photos. It seems like it's 1" after sprayed. Do you have a Web site or email. You could advise me on why the garage is very cold meaning not functional as an insulation. Thank you.
Go stick a probe in the foam and measure the depth that way.
You rock
Is it ok to apply spray foam insulation when the attic is 110 degrees? Will it fully cure? Or will it off gas forever?
Most of the super hot climates have special summer grade foams that will allow the SPF to be sprayed that hot.
It is not so much "cure" as it is to have a controllable pattern.... plus who physically can handle being in that environment?
@@SprayJones thanks so much for responding. I’m just worried about it. There’s no real info about it such as warranty if installed
Peace… Shalom… Salam... Namaste and Thank You so much for All that you are doing to Heal our Mother Earth 🙏🏻 😊 🌈 ✌ 🌷 ❤

Welcome aboard!
Glad to have you around and gleaning info.
You guys spray the studs too ?
Can you do an equipment trouble shooting video?
No. If things continue to grow we will look at a podcast for 2022 geared towards installers and making them better.
@@SprayJones awesome. I've been doing spray foam for a short while now. Your content definitely helps me to improve. Also just watching your spray technique helps me a lot.
@@truthpreppin7630 Thanks. Glad we can help.
Have you made-; since I’m a lazy American and will not manually search your videos-; a detailed video of the many ways the chemicals are not being sprayed properly?
No. Waste of time. We concentrate on doing it right.
Hey I just seen a video about this aerobarrier product? This seems like a scam, what's your opinion
It cannot take the place of walking all aspects of the job and hand-applying caulking.
What is the blue colored material I see on studs and headers?
Spray on caulking for air sealing where there's no room to spray foam
I used closed cell on my walls , can I use closed cell on the roof ceiling in the attic?
Yes.
@@SprayJones would I benefit from a radiant before or after the foam?
@@21gonza21 No, SPF is all you need. Conductive and convective out weigh radiant when in comes to roofs.
Watch the shingle life video I made and see the attic temps with SPF.
What is stated is not true, you have green guard in the states. Most manufactures conform to it that I know of.
Stinky closed cell is somewhat a thing of the past for the reputable manufacturers.
Also if that video being shown is in Canada, then it is over a 2 inch lift which is a no no
I hope you watch more videos and click on some ads, it will be a big help.
You have to have eletric wiring done first ?
Watch the video just released today about wiring.
@@SprayJones yes or no would suffice.
@@madmedic366 Yes you should when the it makes sense to. No you shouldn't, sometimes when the conditions call for it.
I was trying to help direct you to the very question you asked in greater detail.
Any chance you could share your voc testing information.
Go watch the video that just launched.
Do you always spray that much on the studs?
No, depends of how the guys are feeling day.
