Spray Foam Insulation - The Intelligent Choice

by gacinaz • 773,941 views

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.

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. 
Report spam or abuse
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.

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. ...

+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).

Sounds like a great idea but new homes are pretty tight nowadays. What would be the R-value in a 2x4 exterior wall? Thanks.
Report spam or abuse
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.

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.

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.

@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.

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.

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.

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.
Report spam or abuse
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.

Report spam or abuse
@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.
Report spam or abuse
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.

Report spam or abuse
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.

@1ncs It works very well in older homes. I have done home from the late 1800s to current. Depending where you are located make sure it does not have knob and tube wiring as this type of wiring can not be insulated over. You may want to use an 1" or so of closed cell first to provide a vapor barrier and then finish filling the wall with open cell. If you are in a very cold climate use all closed cell as it has a much higher R-Value. In the southwest the combination works well.

@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.

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.
