Spray Foam Insulation is the most energy efficient product you can install in your home, allowing you to lower your heating & cooling energy usage by 50-60%, compared to traditional insulation...

The spray foam in the video is an open cell.  Open cell has an R-value of 3.5 to 4.0 per inch depending on brand.  Closed cell has an R-value of 6.5 to 7 again depending on the brand.  Both are air seals but closed cell is also a vapor barrier.  Closed cell is much more expensive but is the only product that will work in certain applications.
Looks pretty good well done can you use this to fill cinder block?
So the cost seems to be why I do not see this widely accepted? So the reason for high cost is the machine, material? What is your profit margin with this job 50%? .What about moisture, mold? So you are burying water pipes, wiring, not sure about that could be trouble down the road.
Nice cutter! What kind of is it and where did you buy it? It seems like it safe you a lot of time
What spray foam is used here ? What is best foam product are available in the market 
Hello.  In your opinion, how much should it cost spray a 40 X 8 high cube shipping container. walls and ceiling.  I would love to hire you for my project but i am in Florida. 
I love this product. .. What is keeping me from having it applied is the cost. While I understand the cost vs savings over a long period of time, the initial estimates I received made me fall down!! Please tell me why the hell this is so expensive!! It's certainly not labor intensive so why the crazy cost?
Yeah, I got a cost here in the Northeast of $2,000. ... That's a lot especially when you add the cost of me having to remove the ceiling and put it back again. ...
I am thinking about having this done to my attic, but I heard that this stuff contains like 1% asbestos.  Is that actually true?
Najlepšia izolácia pre celý dom!
What happens if you need to modify the plumbing or other things in the house. Is it easy to remove?
+gacinaz Yes but that is very difficult. .. You are better off running some empty piping or conduit before applying the foam. 
I just had it done to my house after watching your video, but it didnt expand as much as yours, do you know why? It is only about 1 to 2 inches thick, is that going to be enough?
Thanks, that helped more than you know
We had our home insulated with foam.  It was about 6 grand in 2004.  Our house is about 1200 square feet and it uses about 350 gallons of heating fuel for a year (home is in Maine). If you can afford it, do it!  You wont be sorry.

This expanding insulating foam is oddly mesmerizing: Spray Foam Insulation - The Intelligent Choice
Spray foam insulation is a good thing to spend some of your money. It has a lot of advantages regarding the foundation and beauty of your home.
how hot and bearable is it in that suit? lol
+gacinaz cool. thanks for answering my questions! 
I've been doing a lot of reading on different types of insulation as we plan to build a home in Michigan. Foam seems like a great insulation, but I do have some questions if anyone can help... I like that this starts off green, but what happens with all of the excess foam that is trimmed off? Can it be reconstituted to be sprayed again, or is it headed for a landfill? I've read a number of complaints about people having severe health issues after moving into a new home that was insulated with foam. In some cases they blame foam in general. In others they blame the installers for not (mixing?) the foam correctly. Has anyone else  heard about these, or know how to tell if you have a "good" installer that can get the mix right? I also see the installers are wearing respirators, so I assume there are fumes. How long do they take to clear, and how long will the foam continue to emit gases? Someone else asked about how hard it is to remove if you need to work on plumbing, for example. When I had to remove even a small amount of GreatStuff to do some plumbing it was miserable. Will I have the same issues, or if I hire a contractor, is my bill going to be higher? Sorry for the long post. I only get a chance to do this once, so I'd like to make sure we make the right choice the first time whether it's foam, cellulose or even recycled cotton insulation (I won't use fiberglass). I'm not willing to sacrifice the safety of my family for better insulation, so any help would be greatly appreciated. Thanks, Tim
+gacinaz Thanks for the quick response! I figured this was not a DIYer project based upon the equipment and the fact that you need training to do it properly. I like to do the work myself where I can, but I also recognize when I would be in over my head. I'm not positive foam is the right choice for me based upon the fact that it isn't a green product top-to-bottom. That is still a very important consideration for me. Maybe foam is the answer, but I want to be thorough in my research. I have found many contractors install multiple types of insulation. quite a few that offer foam also offer fiberglass (yuck!), mineral wool (like fiberglass?), cellulose and cotton (recycled blue jeans)? I know this is moving off topic from foam, but do you have experience with any other types of insulation and or know if there is another choice that is green from its manufacture to how it performs? I have calls into a couple of local installers and have visited H.D. to see what they have, but I feel like I'm being sold what they install rather than what is available. Thanks for your time and thoughts.
Thanks for sharing.  Adding insulation to your home is a sound investment that is likely pay for itself quickly in reduced utility bills.
i'm trying to apply for a job to do this, how hard is it? and i'm left handed, looks like he's doing it right handed, would it be a problem for someone like myself?
They will give u a left handed sprayer.
Sounds like a great idea but new homes are pretty tight nowadays. What would be the R-value in a 2x4 exterior wall? Thanks.
Pretty sure it's R6 or 7 per inch using spray foam if that's what you were asking. But at $2 per 12inches by 12inches by 1inch thick for 2lb. closed cell.... well damb; that's quite the bill.  Also, you mentioned "new" homes... so are we now talking about filling a 2x6 external wall cavity? It makes more sense to find a solution that puts a blanket around a home (as in external insulation), using 2x4 walls(a lesser amount of used natural resources), that will keep the wall warm in the winter and never allow moisture within to condense or frost up and melt later in the wall.
Is this the same stuff as you buy in the spray cans at the hardware store for small jobs?
+TheFarmerfitz . It will stick to that black plastic stuff "BUT" plastic easily peels off spray foam after it is cured. 
+ChasingTruth TakingFlak 1. It does act as a sound barrier, it's not 100%, but it is does reduce noise substantially (if sprayed properly. 2. If you select heavier (more dense) foam it can be very rigid, and there could be a slight possibility for it to crack. But in most cases, it's flexible enough that it shouldn't (I've sprayed vans, moving trucks, semi trucks & never seen it crack) 3.If it's not covered or painted over with a polyurethane coating it will deteriorate over time. after maybe 5-7 years of exposure it'll turn a dark yellow and have a higher chance of cracking. It must be applied to a clean, dry surface (no vapor barrier) and then covered with something (sheet metal, coating, something).
i want the job spraying.....also are you guys just walking around while this guys is breathing through a fresh air system? that might be why he keeps making that face
Is this closed cell or open cell? I didn't hear if you said which it was.
I watch this video to fall asleep, this is mesmerizing
Is it have any EDCs(endocrine disrupting chemicals) or Sick House Syndrome problems?
Can it be used to insulate around a Jacuzzi tub? The builder didn't insulate ours so in the winter, when you really want to use it, you can't keep the water in it hot very long.

My parents had this in a house they built about 10 years ago. One of the most comfortable homes I've ever been in. No drafts and the temp was fairly even throughout. Granted it was a new home so much of that could have been other elements of the construction.
Can you use this for spraying in floor joist in crawl space for floors to be warmer?
hey guys, i got some questions about your setup. what temps and pressure are you spraying at? and what mask. i like the idea of the roll off lenses. 
i like the idea of the page covers. the release doesnt effect vision much? you guys spray demelec heatlok soy 200 close cell? 
How well does it insulate against sound? 
How much will it cost me in the Netherlands? I am preparing to build container housing. And if this is possible in Holland, does anyone of you have any tips on how to actually apply this to the container itself?
I would like to have a product that I can completely be removed in about 10 days.
Is there a liquid product to spray on and remove it if needed? Or how do you remove mass quantities of this product on a rough surface? Is it bio - degradable?
Can you travel to Alvin to spray a 40x60 building?

I still didn't hear the bottom line, whats the per sq. ft. cost?
@viper8red I charge $1.60 per square foot for the first inch, then less for additional. I don't compare foam to fiberglass, because fiberglass should be outlawed like Ford Pintos were...it is unhealthy, it settles signifigantly, it is not an air barrier. Why is your hvac filter made from fiberglass?? Because air goes right through it!!
I doubt it is possible. You need to be able to get within 12 to 18 inches of the area to be sprayed. It might be possible if it is a really small bathroom and you could remove a few more blocks.
for some reason this foam makes me think of ghostbusters
What happens when you renovate and need to change some plumbing or electrical elements? Also, is this open-cell or closed-cell foam you're using? Mspollybee
Whats the name of that automatic knife?
is this open or closed cell foam??? thanks Ron
Any outlets to purchase spray foam in pressurise can in abudahbi uae
The initial cost is 3 to 4 times more but the pay back is 5 to 7 years and then is a positive cash flow. You also have savings with smaller HVAC systems, no attic venting, ducts within conditioned space and improved comfort.
@RowdyRacer17 $5-6 a board foot is what I was quoted right here in Oregon. What do you charge for a 12"x12"x1" of closed cell foam? It's not cheap stuff. It's just as costly doing it at the beginning or later. It's not like it gets any cheaper. It is expensive stuff. Like I said i've never seen it less than 5-10 times more expensive than fiberglass batts.
@Gater180 The open cell spray foam is a soft foam and you can easily remove it to add additional wiring or plumbing. It is an air seal but it will dry from both sides by diffusion so it does not hold moisture or cause the wood to rot.
Great movie for Spray Foam Insulation
Yes it sticks to both flat and sloped ceilings. Most of what we install is on the underside of sloped roofs and in the cavity of flat roofs.
Oh super Thanks for your help never had to use this stuff before .
i have a question,, what is the insulation value on 100 mm. ? fire ? Claus Hotpaper.dk
this is excellent job!!, can we use this foam for gas sealing? we need 0% leakage of gas from compressed gas casted part container??
so whats the r value you get with that open cell low density polyurethane foam in a 2x6?
We are installers in California, USA and are not involved with manufacturing so I don't know.
How is this charged out? By the sq ft, or by the room, or by the amount of foam used?
What do you do with the extra foam that's trimmed off? Is it recycled or a process where you can turn it back to the liquid?
This is half pound and it is not a vapor barrier. If a vapor barrier is needed we spray a latex vapor barrier over the finished foam.
The one in the video is made from a flat plate sander. The sanding plate is removed and the custom made blades are attached where the sanding plate attached. We now use ones made from reciprocal saws and a custom blade adapter.
What can you do if you have a problem with you're plumbing or electrical, in between walls?
@sprayfoamwales Probably because at the moment the cost it astronomical in the uk. When it becomes more affordable it will be used.
Spray Foam is a competitive business just like all other businesses in the United States. There are numerous manufacturers of Spray Foam and if there was the ability to reduce the prices someone would do it to gain market advantage. Yes it is expensive but it takes more than a straight edge and razor knife to install it.
There are two types of spray foam. The video is open cell and it can not be used on the exterior. The closed cell can be used on the exterior if it is painted with an elastomeric paint such as Roof Guard. You need something to stop the UV light.
@malkooth The spray foam is an air seal and does not let air or moisture laden air pass through it. When water leaks into the cavity it will very slowly find its way through the spray foam and dry out.
The one in the video will not work for marine uses as it is open cell spray foam. We have done a number of marine applications using closed cell spray foam. Most of them are Coast Guard approved flotation foam. We have done floating docks, filled barges and filled floating buoys.
@Mandelbiten The spray foam is rated as a Class 1 product. It is approved for both residential and commercial buildings.
I live in Southern CA where the summer temps reach 120 some days. My garage has no insulation in the roof so the garage gets crazy hot. Would this product be a good choice for such an application? And would you recommend the open or closed cell foam? Also, is this product better than other foam insulation in any way? Thank you.
Open cell, as in the video, is very good at sound absorption. It glues it's self to the studs and backing so it never settles and it gets behind and around all of the penetrations, wires and pipes so there are not any gaps. Closed cell is a sound reflector and is very good in preventing outside noise from entering the building.
Yes it is bio-based. We are not resellers of the foam. We are installers. You will need to talk to a spray foam manufacturer to get the cost. Demilec, Gaco Western, SWD, BASF, Bayseal are a few of the manufacturers.
Wouldn't closed cell be even better for sound proofing?
@gacinaz Is that with 1 inch of spray foam applied? When I said 768 square feet, that is the size of my basement, not the area to be treated. I don't know how much area needs to be sprayed. Is there a formula for that? Are band joists fairly standard in size?
@4n6md Depending on the age of the home it may be possible to inject the spray foam into the walls. You need to make sure it does not have knob and tube wiring. If it has knob and tube it must be upgraded first. The crawl space could be sprayed if someone can crawl under it to reach the underside, even if they need to dig out a little of the dirt. I would call Demilec at 817-640-4900 and find a local contractor to take a look.
@SynaesthesiaOfficial It provides superior sound through the wall cavities but you still need to deal with sound through the studs. Build a wall with 2x6 top and bottom plates and 2x4 studs offset side to side then spray foam it. Install 2 layers of drywall over RC1 channel and you will have the best sound booth possible.
@RowdyRacer17 Have you ever priced this stuff out? I have.. in some cases it's 10 times more expensive than a fiberglass bat. That's why not everyone does this! It can be up to $6 a board foot (1"x12"x12". That means a 2x4 foot wall is $12.00 for each square foot of that wall. Thus it can be up to $1000-1500 to do one wall. Yah that's very pricey when you consider that same wall could be less than $100 in fiberglass.
@chisaoboy We are located in Northern CA and deal with hot summer temps also. The spray foam makes a huge difference in the attics. It stops the heat at the roof plane and stops it from entering the attic space. We see a 50 degree reduction in the attic temperature. I would use open cell as it is less expensive and is applied thicker allowing the roof rafters to be buried. Wood rafters do not provide much R-value and having the spray foam cover them stops the thermal transfer through them.
100 mm equals 3.97 inches so the R-value would be R-15. The foam is a class I fire rated product. The studs will burn before the spray foam will. The spray foam will char on the surface.
Polyurethane foam is a great way to insulate your home indeed! You should check out our polyurethanes Passive House project in Brussels, Belgium where we're building and insulating a house using not only spray foam but boards as well!
We actually install the spray foam by injecting it into the wall. This results in minimal overfill and very little waste, about 2 trash bags in a 2,000 sq ft home. The waste is disposed of as trash. The cutting shown in the video is how we did it a few years ago.
They are using a flat tip on that gun so that they get a wide narrow pattern. I prefer a round tip and I box the edges of the studs and then fill the middle.
New construction is better served with a combination of insulated concrete forms and spray foam. The wood frame construction shown in the video is best avoided in new constructions. Spray foam is terrific for renovating older homes.
@WowMike2002 So you would put shitty insulation in your house incase you want to run a cable wire in 5 years??
Are you talking about the walls or a vaulted ceiling or an attic. Usually hot rooms on the second floor are the result of poor insulation in the attic. As the upstairs tries to cool it pulls the hot are from the attic. If it is an attic we go in through the access port, remove the existing insulation and install the spray foam. If it walls or vaulted ceiling we need to remove the drywall.
@gacinaz thx a lot i was thinking about using it that way,instead of absorber mat.
That is absolutely amazing. Great product idea.
We have done a number of cabins in the Sierras. Just need to make sure we can get a 20 foot box truck into the location. We have also done sheds, cargo containers and metal buildings to keep them warm/cool.
@siroatmeal No it does not. It will burn, like all insulations but it just chars on the surface. The current spray foams have either a top coat or a built-in intumescent coating. It the fires that have happened the studs burn and the spray foam is still standing there.
I've a question concerning the HVAC. Since foaming saves 50%, wouldn't the HVAC be far too large for the dwelling? So, what process do you guys follow to insure the home has a properly sized HVAC unit? As you know the HVAC would waste a ton of money if improperly sized not to mention the comfort factor.
This is open cell. You will never see anyone cutting closed cell like they do in the video. It is much harder so we tend to underfill the stud bays so no cutting is required.
No Attic Venting. Been building for 30 years and that's a first.
Gawd help you if you ever have to get to that plumbing or electrical lol
ICF is a very strong and secure wall system. We do a lot of spray foam in the roof assemblies of ICF buildings. The spray foam extends the advantage of the ICF walls into the roof providing an incredibly tight, well insulated building.
@Briansgarage The spray foam is non-offgassing and has been certified by GreenGuard for Children in addition to the standard ICC testing.
Shame that foam manufacturers are being allowed to charge 1000% mark up. There is no reason other than pure greed that these manufactures charge the price they do for this product. The actual material cost to spray 1000sf just 2" thick is probably around $200 and they would charge about $2000+ and DIY foam kits LOL well that would be over $3000! Yes foam is superior BY FAR but the manufacturers are being allowed to go wild with profits.
Yes it works very well for sound studios. The open cell spray foam is very sound absorptive. It fills every crack and penetration and does not settle. You should use 2x4 studs offset from side to side on a 2x6 base to stop any sound penetration through the wood.
If you haven't installed spray foam insulation, then you're missing out and wasting money on energy
I'm just curious.. how can you control waste? Seems like there's about 10%+ waste per area sprayed.
