Hi im doing a projet on Soy Insulation at university of Guelph. I was wandering if it is possible to make one on your own. Or if i want a sample how can i get it?
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!
Very impressive product and video... could've done without the 'fake disbelief' of Kent though "That is UNBELIEVABLE!" :| Made it feel a little patronising.
What are the environmental facts, versus conventional insulation products? Is this available in Australia? Thanks
@quickdrawMMX It is non-offgassing, contains no formaleyhyde, non-ozone depleting and does not support the growth of mold or mildew. It is available in Austrailia. I know that Demilec has installers there.
This would definitely be a very efficient and warm house. The only problem is if you have any electrical problems or plumbing problems you will have to chisel and break all that stuff from around it before you can work on it.
@cloudstrifeification You are thinking of closed cell spray foam. The open cell is a soft spray foam that is very easy to work with after it is installed. About the difficulty as fiberglass but without the itch.
@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.
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.
@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.
When the beams are completely coated the spray foam will reduce the exposure of the beams to the active flames and should extend the time it takes for them to burn. All spray foam that is installed in attics and crawl spaces is either coated with an intumescent coating or has a integral ignition barrier. The spray foam usually just chars on the surface and doesn't burn through except in extremely hot fires where the entire building is going to be destroyed anyway.
Nice video! I'm wondering to what extent spraying this stuff on those OSB I-beams (which, by themselves, are notorious for falling apart in fires) will delay their collapse. Has this been discussed as a way to mitigate the structural problems with "lightweight construction" during fires. Thanks.
@NakedToes The product is a polyurethane. It is non-offgassing, non-ozone depleting, and non-allergenic. It is a petroleum based product that uses renewable castor bean oils. Some of the products we install also use recycled plastics from water bottles.
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.
@1timby You are correct. We use the ACCA Manual J and D to calculate the proper HVAC size. Properly sizing your HVAC system and resizing your duct work to work properly with the new system is critical to achieving the maximum savings and comfort in a home.
Good video - I applied Foam It Green insulation in my own home and it worked great. You can see from the video here too that you have to move pretty fast because it expands super fast.
What happens if you have a roof leak or a wall leak? Does the foam stop the water and you find it later when part of the wall or roof collapses from rot?
@malkooth The open cell will let the water leak down through it and it will dry out. When it drys out it retains all of its original insulating properties.
@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.
@malkooth "Open-cell" spray foam will let water thru, like in the event of a roof leak due to hail damage etc... The closed-cell spray foam will not let water through. Open-cell foam has an air barrier of about 3 inches. We put it in all our new homes, it's amazing stuff.
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.
@WowMike2002 Actually with the open cell spray foam shown in this video it is not hard to run wiring at a later date. If you use closed cell spray foam it is a different story.
@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.
@viper8red - My crew and myself spray foam all day every day, in everything from well pump houses to large homes. I have had customers whose foam was PAID FOR before the structure is even built. Less HVAC tonage, no vents and related installation, etc. Planning foam into a house from the beginning will result in surprisingly small cost increase. Foam insulation is not just for rich people, it is for smart people.
@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.
@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!!
@viper8red well who ever is quoting you that is absurd, we charge $.90 a board ft. At 3" we typically are in the $2.70 range for an r rating of 21. Pricing will vary obviously from location to loaction but $6.00 an inch will probably be the reason that company goes out of business. Just like I reccomend to our customers is price match do your homework , and for what you get out of foam whether open cell or closed cell the benefits are SO SO much better than fiberglass.
@WowMike2002 So you would put shitty insulation in your house incase you want to run a cable wire in 5 years?? Fiberglass should be outlawed like the Ford Pinto was.
@bkedp It is similar in that they are both spray foam. The product we use is a two part spray foam that is mixed at the tip of the gun which starts the reaction. This creates a much more consistent product that adheres to the surface and does not fall out.
This is an awsome product ! I have a delema that I hope you can help me with ; I recently purchased a rowhome that has the kitchen extended to include the 8 x 12 back porch, the walls and ceiling areas are finished and insulated. The kitchen is always cold. The floor is not insulated. there is about 12 inches of crawl space under this area, DO you have any advice ? Thanks in advance.
@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.
Is spray foam insulation optimal for sealing the band joists in my basement? I currently have NOTHING on there now and my energy company auditor encouraged me to insulate it. I've done my own reading on this and it's overwhelming how much information there is. SEALING the air is allegedly the most important thing, not R-Value. Does this mean that spray foam is the best option? How much should I have to spend for a 768 square ft band joist spray foam insulation project?
@dogfan4lyfe Yes, insulating the band joist is very important to the overall insulating of the building envelope. While R-value is an important measure it doesn't mean anything if the structure is leaking air through or around the insulation. Spray foam is a complete air-seal and stop the air infiltration. Depending where you live you should expect to pay $2 to $3 per square foot. Small jobs are more expensive due to the setup time.
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?
@dogfan4lyfe The price I gave you was for R-21 to R-30 being installed. Depending where you live the amount you need will vary. In CA R-21 is all you need but in the midwest or north east I would go with R-30. I would prefer to do the entire subfloor if the basement is not conditioned space. There is a lot of air leakage in a subfloor. The band joist is the only part that is exposed to the outside so that is the most important if you have sealed walls and floor in the basement.
@moviesforrandy In the application method shown in the video the waste is thrown away. We now use an injection system where there is minimal waste but the little bit there is must be disposed of.
@perkinsfan Spray foam is 3 to 4 times more expensive at the time of installation. The advantage is that it is an air-seal. Air-sealing is the most overlooked and least understood building science. Air-sealing reduces energy costs by 50 to 60 percent. Closed cell spray foam is a vapor barrier which may be missing in older remodel projects. Refrigerators and ice chests use foam insulation because it is far more effective.
@MsPollybee This is open cell in the video. We do both. With open cell it is very easy to remove an area and do your renovations. The foam is soft and you can push romex or piping through it with \out removing it. Closed cell is much more challenging as it is very rigid and needs to be cut out with a saw.
@789mark Insulation under the roof sheathing does not cause the shingles to overheat and age prematurely. Testing by the roofing industry shows that there is about a 1/2 degree temperature difference. Color of the roof can make as much as a 10 degree temperature difference. All major roofing manufacturers fully honor their warranties.
I have a house that was built in the 50's with a finished basement and main floor has plaster walls. I have to remove the plaster walls and replace them with drywall. Would this form of insulation work for a house at was built in the 50’s
@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.
What exactly are the ingredient in this formula? It says "plant oil" but their are a lot of types of oil such as corn or soybean but as individuals we can be allergic to its components. And what is the name of this said solution.
@HappyNinjaLlama The plant oils used vary by product. Some contain soy oil, some contain castor bean oil and some contain sugar cane oil. The only way to know what is being used in the product you select is to ask the installer. The plant oils are a minor part of the mix. The major component in all poly urathanes is petroleum. The product in the video uses castor bean oil.
@bigtananabig You can not use this exact foam but you can use closed cell spray foam. It is very hard when it is set and can be painted with elastomeric or water based latex. It does need to be painted with something to protect it from UV Light.
Interested in soundproofing the garage. Don't like waking up the neighborhood when I've got the tools going. Is spray foam for garage insulation more effective at reducing/eliminating noise than batt insulation?
@canucksvrider Spray foam works very well for sound control. Because it adheres to the studs and sheathing it does not leave any gaps or voids that allow the sound to escape. I have used it for sound control in a residential metal cabinet shop where the customer liked to work at 3 or 4 in the morning. It stopped all of the complaints.
@irishchrisc It is the air seal and internal air bubbles that make it an insulator. Voids and cracks are areas where there is a gap in the insulation allowing infiltration through a material. The areas along the studs where the fiberglass insulation pulls away and does not provide a seal are voids.
I had my walls spray foamed. All though I love it, the drywallers HATED it. You have got to make sure they trim it flush with he walls or your drywall is going to look like crap
@Galt425 Yes the foam completely cures in about 30 seconds. The foam is rated as non-offgassing and meets the requirements of GreenGuard and GreenGuard for Schools and Children. It contains no formaldehyde.
PLEASE COME DO MY LITTLE HOUSE IN FLORIDA. IT IS 140 DEGREES IN THE ATTIC NO INSULATION AT ALL. 90 DEGREES IN THE HOUSE WITH THE A/C BLOWING 62 DEGREES
@Devrionde Yes this can be used in brick homes. Depending where it is being applied you may need to use closed cell spray foam instead of open cell. If it is going directly against the brink then closed cell is the proper material. If there is a drain plane between the brick and the walls are fully sheathed then open cell is appropriate and is applied on the inside of the sheathing.
Would this product be ok to use it an older home? I am redoing a master bedroom on a house I just bought and I broke up all the old drywall..now that the walls are open I might as well upgrade insulation. Does this expanding foam put a lot of pressure on the studs when it expands..would it crack an older frame?
@mission762008 This product is excellent for older homes. We use it in a lot of old 1800 and early 1900 homes that are being remodeled. These older homes are very leaky and the spray foam seals up all of the holes and cracks. It does not harm the framing and in fact it helps tighten it up. We usually use the closed cell version as it adds structure to the building and a vapor barrier. Do not insulate with any kind of insulation if you have knob and tube wiring.
@dieselplow R-Value is measured per inch. The problem with R-Value is that it is a laboratory measurement and does take into account how the insulation is installed or how the building is built. The only effective measure of an insulation's effectiveness is an IR camera and blower door test. R-Value only measures a small part of the energy efficiency equation and yet most people think it is the only factor.
@gacinaz Can this product be left open to the public or does it have to be enclosed by drywall or other? We are building a new office building - using a steel building - can we leave the ceiling open and just paint it white? Or do we have to frame in the ceilings and put in drywall? I am not sure if there is flaking or chemical release that has to be enclosed in by a wall material.
@dieselplow It requires a 15 minute thermal barrier. This is normally the drywall but if you want to leave it exposed you can have BlazeLok coating spray applied over the foam and it will meet the code requirements. After the BlazeLok is applied it can be painted any color with a latex or elastomeric paint. There is not any flaking or offgassing. The 15 minute thermal barrier is a building code requirement for all insulation in a conditioned space.
@dieselplow Yes BlazeLok is an intumescent coating that we apply with an airless sprayer. It has a flat dull white or gray finish. We apply about 13 mils of it (10 mils when dry). It is similar to what they use on NASCAR and NHRA cars.
@AmazingFoamInsulatio We do conduct blower door testing and use IR cameras and spray foam is much better due to the air sealing it provides. Air sealing is the key to having an efficient insulation system. The only time I recommend cellulose is in closed spaces where it is not possible to install spray foam. We use the Demilec products, both open and closed cell.
I live in Oklahoma City and my house has so much hail and water damage that all of our drywall is coming down and the old insulation is coming out and the roof is being replace with a TPO Roof. We want to do spray foam insulation. However, we are not sure if it will work here since its so humid here. Also, any thoughts on what it would be to do a 2,500 sq ft 0ne story house?

@bearboyok There are 100s of homes in your area that are using spray foam insulation. We do homes on the Pacific coast, in the mountains and there are a number of installers in Washington and Oregon where it is also quite humid. The factory is located in Arlington Texas where it is also very humid. It is an air-seal and works very well in humid areas. For local installers in your area call 877-336-4532 and they can connect you to someone in your area.
@johne0408 Spray Foam normally adheres to concrete very well. If the concrete is very old and loose the problem may be that the surface of the concrete is not adhered to the underlying concrete. Remove the loose surface areas and any powdery residue before applying the spray foam. Use a closed cell spray foam to mitigate moisture transfer through the concrete.

@lilo5456 Yes by spraying it on the underside of the roof it will stop 98% of the heat transfer thru the roof. It is a complete air seal so it keeps the conditioned air inside where it belongs. It can also be sprayed into the walls again providing an air seal keeping the conditioned air inside.
How well does this insulate sound? I am looking to insulate my shed so that my neighbors are not disturbed by my drum kit which I have set up in there. Would this do the job?
@overninethousands Spray Foam works very well as a sound insulator. I have done many home theaters, dance clubs and video recording studios. Open cell absorbs sound and does not leave spaces and gaps where the sound can escape. If possible it would also be advantageous to put resiliant channel on the walls and then apply Quietrock. The wood or steel framing that are not covered with the spray foam will still transmit the sound otherwise.
hello. how is this type of insulation used when the house is fully constructed with existing walls that are covered in drywall and plaster? We have an old(1892) victorian home that's been renovated in the last 20 years but it's drafty. I'd like to be able to use this technology without tearing into all the walls if that's even possible.
@nacholibreconcarne This depends a lot on where the home is located. In California we do not have a good way to inject the spray foam into the closed walls. There are a couple of products on the market designed for this but they are not allowed in California due to off-gassing and chemical makeup of the product. The first thing to check is the wiring. Homes of this age used knob and tube wiring which I hope was replaced during the previous renovation.
@nacholibreconcarne PART 2: If the wiring has been upgraded then I would suggest having cellulose blown into the walls. This can be down thru a series of small holes drilled in each stud bay. The Spray Foam could be used to insulate the attic and crawl space which account for about 80 percent of the energy loss.
@bigavelli13 The video is open cell 1/2 pound spray foam. It expands 1200 % in about 3 seconds. We also install closed cell which only expands 300 % and takes about 20 seconds. Due to the moderate climate in California open cell is more common.
Yes we have used this in home theaters, HD TV Studios, interior sound walls and between floors to provide sound control. Since it glues its self to the studs and backing it remains in place permanently and does not leave gaps or cracks for the sound to penetrate.
A company that installs this type of insulation spoke at an ASHI meeting. They also touted the structural benefits of installing this type of foam for binding the structure together.
@vandstra They were talking about high density foam, 2 pound. The foam installed in this video is low density, probably 1/2 pound. Both are very good products.
How much more expensive is it vs traditional fibreglass insulation...? Also how much more effective is it compared to other types of insulation...? Thanks in advance.
Spray Foam Insulation costs about three times more that traditional fiberglass at the time of installation. It is about 50 percent more efficient than other insulations as it provide a complete air seal. DOE says that air leakage in a new structure accounts for 40 to 50 percent of your heating and cooling costs. With a properly air sealed home all of the conditioned air is retained in the structure so you are not paying to condition the great outdoors.
I live in Dallas Texas large home roof sheathing is radiant foil which is nice keeping the attic cooler but it still gets hot. From what I've read here, spraying the underside of my roof would be okay but would negate the radiant barrier. The trade off is I get an insulated attic. But unless I air condition the attic, it still will heat up. Would it be better to foam between the ceiling joists instead (replacing the blown in insulation)? Would I use open cell?
When spray foam is applied to the underside of the roof sheathing it prevents the heat from getting into the attic. The attic becomes part of the envelope. The blown in on the ceiling floor should be removed. You do not need to air condition the attic. The attic will stay within 5 to 8 degrees of the house temp. The duct work will now run through an 80 to 85 degree attic instead of a 140 degree attic. This reduces the load on HVAC by 25 - 30 percent. Open cell is the best choice.
Yes the spray foam can be applied directly to the underside of the roof sheathing. The vapor barrier requirements vary by geographic zone. Hot dry climates, usually zones 1 through 5, have a vapor drive from the outside to the inside so the vapor barrier is on the outside of the roof. other climate zones do require an interior vapor barrier and it is sprayed on over the foam. Closed cell spray foam is considered a vapor barrier at 2 inches or thicker but that is not always a good thing.
Open cell spray foam is not a vapor barrier so it needs to have one spray on if required. There is a lot of differing opinions regarding vapor barriers in the building science community but local building code always rules.
Cutting the surface of the spray foam has no effect on the spray foam. The foam has the same properties throughout the foam. We do use some different injection methods now but that is purely to reduce the waste.
i insulated my attic in laredo texas with this sealection 500 product. it really saves on my electric bill an average of 145.00 dlls a month i recomended to every one, the company that did the work is called apply-tek. superb work!!! this foam rocks!!
Thats weird, I had two estimates and both of them told me they don't want to cut it because it loses some of its insulating value. I have to trust what they tell me.
The product a Class I rated product with a Flame Spread Index of 21 and a smoke developed index of 216. What all this means is that it is rated better than any other kind of insulation except rock wool. The studs will burn long before the spray foam will. It is rated for both residential and commercial buildings.
Yes, We do attics and crawl spaces every day. Adding an air-seal insulation to the attic and crawl space reduces about 80 percent of the air infiltration in the house.
Open cell spray foam will be about 13.3 at the low end and 15.6 at the high end. Closed cell spray foam will be about 20. The spray foam we use is non-offgassing so you are not adding any chemicals to your home. It is also non-toxic and non-allergenic.
I doubt that the initial cost of installation will be reduced. It has a 3 to 5 year payback based on energy savings and as energy costs continue to rise the payback will be even shorter. It is a matter of comfort and energy savings. On the average new home you are looking at between 1 and 2 percent of the total budget yet it provides the largest return on investment of anything in the structure.
It can be done if you are able to remove a band of siding from the outside of the wall or if you are willing to remove an 18" band of drywall. Then it can be correctly. I have not seen acceptable results when it is just injected. Too may gaps and holes and a lot of bulging drywall.
If you are talking about the gap between the AC and the wall the answer is yes. Get a can of low expanding spray foam at the hardware store and apply a small bead into the gap. Wait 24 hours before installing more as the can spray foam expands very slowly.
Spray foam is the absolute best way to go. For the absolute best thermal envelope use spray foam to stop conductive heat and radiant barrier foil as a house wrap instead of Tyvek to stop radiant heat flow. High performance builders are combining the two products for maximum efficiency. Great video!
It looks like its safe to spray directly on to electrical wiring, what about spraying on things that get hot like recessed lighting? Thanks, great video and great responses.
You would need to build a box around the recessed lighting so that the foam is not coming into contact with the warm surfaces. There are definitely risks involved with direct contact or overheating - this goes for both 1/2lb and 2lb foam.
Recessed lighting, even the IC rated lighting was not designed to be enclosed in an air tight insulation like spray foam. The spray foam works so well that it can cause the thermo couplers to shut the lights down. We use a box or something that is air permeable around the lights to allow air circulation through the light to keep it cool. We then insulate up to and over the box to finish the air seal.
and what happends if you have a repaire to do in back of the wall after a few year or by mistake you put a nail trough the water pipe like where/when would you see the leak?
It is not a problem to repair. The foam is soft and romex or a fish wire can be pushed through it. Depending on the size of the leak you would know in seconds to minutes. The foam can also be removed by hand and then replaced using can foam.
So i guess i need a dehumidifier huh? I have about 850 sq ft, I can get one at Lowes for about 250.00, it is expensive but my tools are more expensive than that, my lathe tools alone cost as much ha ha. thanks,
I don't think so. In fact I think it will make the problem worse as it will draw hot moist air into the building from either other vents, around doors and windows and will also increase the temperature of the air inside the building causing the metal and tools to condensate even more. You need a way to reduce the humidity.

@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.

When the beams are completely coated the spray foam will reduce the exposure of the beams to the active flames and should extend the time it takes for them to burn. All spray foam that is installed in attics and crawl spaces is either coated with an intumescent coating or has a integral ignition barrier. The spray foam usually just chars on the surface and doesn't burn through except in extremely hot fires where the entire building is going to be destroyed anyway.

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.

Less HVAC tonage, no vents and related installation, etc. Planning foam into a house from the beginning will result in surprisingly small cost increase. Foam insulation is not just for rich people, it is for smart people.

Is spray foam insulation optimal for sealing the band joists in my basement? I currently have NOTHING on there now and my energy company auditor encouraged me to insulate it. I've done my own reading on this and it's overwhelming how much information there is. SEALING the air is allegedly the most important thing, not R-Value. Does this mean that spray foam is the best option? How much should I have to spend for a 768 square ft band joist spray foam insulation project?
dogfan4lyfe 1 year ago
@dogfan4lyfe Yes, insulating the band joist is very important to the overall insulating of the building envelope. While R-value is an important measure it doesn't mean anything if the structure is leaking air through or around the insulation. Spray foam is a complete air-seal and stop the air infiltration. Depending where you live you should expect to pay $2 to $3 per square foot. Small jobs are more expensive due to the setup time.
gacinaz 1 year ago
@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?
dogfan4lyfe 1 year ago
@dogfan4lyfe The price I gave you was for R-21 to R-30 being installed. Depending where you live the amount you need will vary. In CA R-21 is all you need but in the midwest or north east I would go with R-30. I would prefer to do the entire subfloor if the basement is not conditioned space. There is a lot of air leakage in a subfloor. The band joist is the only part that is exposed to the outside so that is the most important if you have sealed walls and floor in the basement.

@perkinsfan Spray foam is 3 to 4 times more expensive at the time of installation. The advantage is that it is an air-seal. Air-sealing is the most overlooked and least understood building science.

Refrigerators and ice chests use foam insulation because it is far more effective.

@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.

@mission762008 This product is excellent for older homes. We use it in a lot of old 1800 and early 1900 homes that are being remodeled. These older homes are very leaky and the spray foam seals up all of the holes and cracks. It does not harm the framing and in fact it helps tighten it up. We usually use the closed cell version as it adds structure to the building and a vapor barrier. Do not insulate with any kind of insulation if you have knob and tube wiring.

How is the R Value of this judged? inches?
dieselplow 1 year ago
@dieselplow R-Value is measured per inch. The problem with R-Value is that it is a laboratory measurement and does take into account how the insulation is installed or how the building is built. The only effective measure of an insulation's effectiveness is an IR camera and blower door test. R-Value only measures a small part of the energy efficiency equation and yet most people think it is the only factor.

@gacinaz Can this product be left open to the public or does it have to be enclosed by drywall or other?

I am not sure if there is flaking or chemical release that has to be enclosed in by a wall material.
dieselplow 1 year ago
@dieselplow It requires a 15 minute thermal barrier. This is normally the drywall but if you want to leave it exposed you can have BlazeLok coating spray applied over the foam and it will meet the code requirements. After the BlazeLok is applied it can be painted any color with a latex or elastomeric paint. There is not any flaking or offgassing. The 15 minute thermal barrier is a building code requirement for all insulation in a conditioned space.

@johne0408 Spray Foam normally adheres to concrete very well. If the concrete is very old and loose the problem may be that the surface of the concrete is not adhered to the underlying concrete. Remove the loose surface areas and any powdery residue before applying the spray foam. Use a closed cell spray foam to mitigate moisture transfer through the concrete.

@overninethousands Spray Foam works very well as a sound insulator. I have done many home theaters, dance clubs and video recording studios. Open cell absorbs sound and does not leave spaces and gaps where the sound can escape. If possible it would also be advantageous to put resiliant channel on the walls and then apply Quietrock. The wood or steel framing that are not covered with the spray foam will still transmit the sound otherwise.

nacholibreconcarne 1 year ago
@nacholibreconcarne This depends a lot on where the home is located. In California we do not have a good way to inject the spray foam into the closed walls. There are a couple of products on the market designed for this but they are not allowed in California due to off-gassing and chemical makeup of the product. The first thing to check is the wiring. Homes of this age used knob and tube wiring which I hope was replaced during the previous renovation.
gacinaz 1 year ago
@nacholibreconcarne PART 2: If the wiring has been upgraded then I would suggest having cellulose blown into the walls. This can be down thru a series of small holes drilled in each stud bay. The Spray Foam could be used to insulate the attic and crawl space which account for about 80 percent of the energy loss.
I hope this helps.

MrThingy3 1 year ago
Spray Foam Insulation costs about three times more that traditional fiberglass at the time of installation. It is about 50 percent more efficient than other insulations as it provide a complete air seal. DOE says that air leakage in a new structure accounts for 40 to 50 percent of your heating and cooling costs. With a properly air sealed home all of the conditioned air is retained in the structure so you are not paying to condition the great outdoors.
gacinaz 1 year ago
I live in Dallas Texas large home roof sheathing is radiant foil which is nice keeping the attic cooler but it still gets hot. From what I've read here, spraying the underside of my roof would be okay but would negate the radiant barrier. The trade off is I get an insulated attic. But unless I air condition the attic, it still will heat up. Would it be better to foam between the ceiling joists instead (replacing the blown in insulation)? Would I use open cell?
FreddyKoshMusic 2 years ago
When spray foam is applied to the underside of the roof sheathing it prevents the heat from getting into the attic. The attic becomes part of the envelope. The blown in on the ceiling floor should be removed. You do not need to air condition the attic. The attic will stay within 5 to 8 degrees of the house temp. The duct work will now run through an 80 to 85 degree attic instead of a 140 degree attic. This reduces the load on HVAC by 25 - 30 percent. Open cell is the best choice.
gacinaz 2 years ago
Can you apply it to the underside roof decking? Is a vapor barrier needed? If so could you explain I've heard both yes and no.

Blgtn43 2 years ago
Yes the spray foam can be applied directly to the underside of the roof sheathing. The vapor barrier requirements vary by geographic zone. Hot dry climates, usually zones 1 through 5, have a vapor drive from the outside to the inside so the vapor barrier is on the outside of the roof. other climate zones do require an interior vapor barrier and it is sprayed on over the foam. Closed cell spray foam is considered a vapor barrier at 2 inches or thicker but that is not always a good thing.
gacinaz 2 years ago
Open cell spray foam is not a vapor barrier so it needs to have one spray on if required. There is a lot of differing opinions regarding vapor barriers in the building science community but local building code always rules.

Whats the R value in a 2x4 wall with this spray foam? What kind on chemicals is it adding to my home?
dchrbac51 2 years ago
Open cell spray foam will be about 13.3 at the low end and 15.6 at the high end. Closed cell spray foam will be about 20. The spray foam we use is non-offgassing so you are not adding any chemicals to your home. It is also non-toxic and non-allergenic.

Will this stuff ever get any cheaper?
kchedville 2 years ago
I doubt that the initial cost of installation will be reduced. It has a 3 to 5 year payback based on energy savings and as energy costs continue to rise the payback will be even shorter. It is a matter of comfort and energy savings. On the average new home you are looking at between 1 and 2 percent of the total budget yet it provides the largest return on investment of anything in the structure.

Anyway to apply this or similar method to existing/finished walls?
Grizzlee310 2 years ago
It can be done if you are able to remove a band of siding from the outside of the wall or if you are willing to remove an 18" band of drywall. Then it can be correctly. I have not seen acceptable results when it is just injected. Too may gaps and holes and a lot of bulging drywall.

Can i use such a spray foam around the air conditioner, towards the inside of the room? I have a lot of cold draft problem from around AC.
mamatalu 2 years ago
If you are talking about the gap between the AC and the wall the answer is yes. Get a can of low expanding spray foam at the hardware store and apply a small bead into the gap. Wait 24 hours before installing more as the can spray foam expands very slowly.

Spray foam is the absolute best way to go. For the absolute best thermal envelope use spray foam to stop conductive heat and radiant barrier foil as a house wrap instead of Tyvek to stop radiant heat flow. High performance builders are combining the two products for maximum efficiency. Great video!

It looks like its safe to spray directly on to electrical wiring, what about spraying on things that get hot like recessed lighting? Thanks, great video and great responses.

You would need to build a box around the recessed lighting so that the foam is not coming into contact with the warm surfaces. There are definitely risks involved with direct contact or overheating - this goes for both 1/2lb and 2lb foam.

Recessed lighting, even the IC rated lighting was not designed to be enclosed in an air tight insulation like spray foam. The spray foam works so well that it can cause the thermo couplers to shut the lights down. We use a box or something that is air permeable around the lights to allow air circulation through the light to keep it cool. We then insulate up to and over the box to finish the air seal.

and what happends if you have a repaire to do in back of the wall after a few year or by mistake you put a nail trough the water pipe like where/when would you see the leak?
speedygonzalez22222 2 years ago
It is not a problem to repair. The foam is soft and romex or a fish wire can be pushed through it. Depending on the size of the leak you would know in seconds to minutes. The foam can also be removed by hand and then replaced using can foam.

So i guess i need a dehumidifier huh? I have about 850 sq ft, I can get one at Lowes for about 250.00, it is expensive but my tools are more expensive than that, my lathe tools alone cost as much ha ha. thanks,

Will an attic fan mounted on a wall work?
dannypw3 2 years ago
I don't think so. In fact I think it will make the problem worse as it will draw hot moist air into the building from either other vents, around doors and windows and will also increase the temperature of the air inside the building causing the metal and tools to condensate even more. You need a way to reduce the humidity.
