Heating and air account for @ 40% of your total energy bill. Now go to 1:44. Crooks, they are all liars. You won't even save up to 50% of just your HVAC costs. You won't save anywhere near 20% of your energy bill even in retrofit. And thats after investing thousands of dollars. In new cost. when compared to other insulations, it will INCREASE your energy bill. It can NOT perform to the r-values/thermal mass of it's competitors, is a plastic, and costs much more at the same time. Make sense?
@turbo69bird are you an idiot? I ask this in a serious way?
Do you consider dirt (as in normal Earth) to non-green? Well if someone was spraying dirt into the air, it would be smart to wear a respirator. ANY dust, no matter how "green" it may be, should be keep out of the lungs and body.
The only SHEEP here is YOU. Next time THINK before you speak.
Funny thing is you have never taken a full breathe of particulate free air in your life, so is it unhealthy? You wouldnt know would you! You gonna walk around with a repirator on? Since dust and pollen and god only knows what have been in nearly every humans breathe from the beginning of humans, WTF makes you think its "unhealthy"? "ANY dust, no matter how "green", should be keep out of the lungs and body" you an idiot? Seriously? "Well if someone was spraying dirt into the air" like wind idiot?
@HomeEnergyNow I agree with what the other people have said about you, you're an idiot. When the wind is blowing up a lot of dust, any normal person would cover their mouth and get away from it. When someone is spraying something into the air in a closed house, no matter what it is, any normal person would use a dust respirator to stop the particules from entering their lungs.
You can compare that to walking down the street breathing in dust, but that just makes you look even more stupid.
@voltagehz Youre the "dr" claiming that any dust is bad for you. Go to a new construction site, tell me how many are wearing respirators. They wear them for insulations that are harmful, paints, NOT DUST. Stay inside, keep that skin plenty pale, the discussion was on the NON greenness of foam, are you saying it is as green as dirt? What exactly is your point? You wear a dust mask when they spray water in a new home? Wet mud for walls? Please make it more obvious you know jack about construction!
@voltagehz Another comment by you having nothing to do with the video. Spray foam installers are REQUIRED to wear respirators because overspray can expand in your throat and suffocate you fast. There is no such thing as required dusk masks for "dusty days" in construction. There is no dust particulate counter with an alarm to say, over this amount of dust in the air is all of a sudden unhealthy. Spray foam is far from green, are saying it IS green? Please have a point.poly-anything can be green?
@HomeEnergyNow Keep digging your hole and making yourself look like even more of an idiot. The fact of the matter is that no one wants any dust of any type in their lungs if they can avoid it. The fact that someone wears a respirator when spraying something into the air does NOT mean that whatever they are spraying is not "green". That is what I said and that is a fact. You can argue it until you are dead, it won't change anything. No one cares what you have to say.

@HomeEnergyNow For being a "licensed builder" that builds 30+ homes a year, you sure have a lot of free time to sling your mouthy, arrogant, insulting BS all over the internet & youtube! Beware the jackass that loves to hear himself speak! Self Praise is no recommendation...
@red80camaro At least the comments have something to do with the video, moron. Maybe we can discuss how I am typing, not speaking, and not once used "self praise". Let me guess, you are making payments on spray foam? "mouthy"? you take idiot to the extreme, bet your a fan of spray foam. Heres an idea, if you don't believe what I say about foam, prove me wrong dipshit! Worst max R value: Spray Foam Highest cost/R: Spray Foam. What are you? Doing some research before remodeling your van?
@HomeEnergyNow You a whiny, butthurt little troll? Spray foam stealing all your business? Typing is another way of "voicing" your opinion, dumbass. And you praise yourself, your work & your false sense of superiority all over the place. I'm a fan of researching all options & deciding based on facts & expert opinions, not the ramblings of an ignorant, blathering jackass in yotube comments. Where are all the houses you've built? Website? Business name? Customer testimonials?
@red80camaro How do I praise myself? I do have a building performance license and I can figure a btu load and ROI. This is the discussion right? Foam performance? CAN06347 is that number, what is yours? You "research" all the options by going to the option "snake pit" called the internet, or do you look around and see that over 95% of insulation jobs are not spray foam? I am trying to help your research, try learning to do a btu load calculation on a home, calculate foam, see it's a bad choice
Until I see one case of someone dying as a result of their home being "too tight" I can't really agree with that. People that spray their homes right, always end up having positive effects...I have yet to see one person say..."Spray foam has made this house less efficient and the living area is uncomfortable." If it costs more than the return is...well, that is a persons choice. Dollars in vs dollars out is not the only factor in doing things.
@amusingisthedawn I can promise you one thing, the smells alone aren't worth it. Forget to use the shitter fan and half your house smells like it. What positive effects? It aint saving money, it cannot be comfort, and since they can be much tighter w/out foam, it aint less draft.Other than comfort and health, performance is ALL there is left. If your goal is comfort and health, foam isn't the choice. If your goal is saving money, dollar for dollar is all that matters. Choice yes, based on lies
Even here in a hot climate they push spray foams, doesnt anybody realize that in hot climates thermal mass becomes an important factor just as R-value has always been? Spray foams might have similar R-value(just in walls, less than half the Rvalue in ceilings), they have the worst thermal mass rating. Spray foams are snake oils, keyboard warriors may never realize this, but thankfully over 99% of builders won't use the garbage.
The fact that insulation makers would even bring up air sealing is retarded. Every wall in this country is required to have two air barriers, and these companies think they have re-invented the wheel by offering a third barrier for air. It is not very hard to seal the existing two barriers and that is the #1 reason insulations that air seal arent worth any more than insulations that JUST DO THEIR JOB AND INSULATE. R-value comparisons will show, spray foam is the worst insulation on the market.
I'm confused...how is spray foaming the area behind the living space bad? If you have a taped and spackled 5/8" sheet rock home...isn't that air tight? All homes have an air tight living space to begin with. Replacing fiberglass with foam doesn't seem like that big of a deal.
@amusingisthedawn Houses HAVE to exchange air ASHREA standard is .35 air changes/hr. Most new homes w/no sealant are @.35. If you don't get .35ach you risk health problems due to all of the products used w/in a home. What is funny, spray foam usually only tightens a house to about .25, then they caulk stuff and get them down to .15. Then the A/C guy usually just pokes a hole and sucks .30ach straight in, negating any sealing the foam did. The customer pays thousands extra for inferior insulation
@HomeEnergyNow Unless they spray the foam themselves and don't care about some standard. Then they save money and chances are...they will not suffocate. I still don't understand how a sealed sheet rock room will change its air exchange by using foam behind it vs fiber behind it.
@amusingisthedawn Drywall doesnt seal perfect. Ever seen drywall installed? It doesnt fit tight against the plates there is always a gap, the perfect place for fresh air to enter really. 1/8 gap all the way around the house makes for a very even flow of fresh air. They may not suffocate from a tight house, but the VOC will cause health problems and possibly cancer. Really? You are going to risk cancer, and live in a house that will constantly smell like the last item you cooked to save 5$/month?
@HomeEnergyNow If you are saying the off-gassing from a table is going to cause cancer....you may be right, but i don't think it matters if the home is .15 tight or .35 tight. Most painters caulk the seams on baseboard moulding which would negate any fresh air from entering. I suppose anyone that lives in a geodesic dome made out of concrete is dying from the moment they enter the home as well because of how tight it is sealed.
@amusingisthedawn Air stratification and moisture distribution within a dome are unusual, and these conditions tend to quickly degrade wooden framing or interior paneling. This is from wiki on domes. You can ask ASHREA about the .15ach but it shouldn't matter, a licensed HVAC professional has no choice but to follow the standards behind their license, so if an HVAC guy allows .15 and somebody gets harmed, I would say they are liable for the life of those homes. The V in HVAC is for fresh air.
As a builder I am biased towards any supter tight home. To see people having to spray entire walls to get their houses tight is hillarious, but stupid people are out there. You would think if they were going to spend all that $ on insulation, they would at least have a better R value, BUT IT'S WORSE! LOL. Super tight homes are dangerous, NEVER let your families health hinge on a filter being clean, or a moving part such as an ERV. The only people I know recommending them, are not good builders.
ERV systems sound great, but it doesnt matter. People are stupid, you hav to build houses knowing this. You CAN NOT install mechanical ventilation if concerned about the occupant, which could change every year. How many occupants would ask about an ERV? You mean that black box thing by our furnace? My customers hardly change their regular filter, now you will let them harm themselves for forgetting they have a second filter hidden in an ERV?Plain book fag building, get your heads out of the dirt
@HomeEnergyNow YOU ARE PEOPLE! A person is smart, so I guess that leaves you out. Obviously you can install mechanical ventilation, because people are people and they all need fresh air, and buildings need to get moisture OUT! The only way is to circulate Fresh Air... That's so simple, even YOU should be able to understand it. I hope your customers are reading this so they know what you think about them. I wish I could think the way that you do, but I can't get my head that far up my ass.
Look at attic ventilation, NO home 20 years old still has its original attic fan. Look at homes even a hundred years old with passive ventilation, still working like a champ. You don't risk occupant health, you don't risk occupant health, you don't risk occupant health, why don't you understand that? ERV's are rarely insatalled right, when they are, they don't last. IAQ hinges on a fan motor made in indonesia, no thanks.You cant understand if you don't build homes you are just extreme ignorant
2: Who did the math to make sure the ERV what set right? I wouldnt trust them!
3: Dirty filter, no not that one, you need a tool to get into that black box, then you need to special order a filter, then you need to install it and hope it will last more than a few months at that price.
4: Neighbor thought they were helping with wasps, and sprayed pesticide on my air intake...OOPS.
5: People I know w/ERV's use their windows ALOT! LOL
@HomeEnergyNow It is rare to see someone SO biased who claims to be UNBIASED. Go on denying the facts. 80+% of the insurance claims and problems with buildings are in their porous envelopes. Air penetration through the envelope carries toxins and particulates that you and your customers are ingesting and breathing. Air introduced into the envelope of an air-sealed building, tempered with an ERV and cleansed via a filtered mechanical system is infinitely healthier; saving 60%+ on energy costs...
@acversusdc I am a builder stupid, 80% is MOISTURE. Obviously you are the biased one here. You refuse to use a single ROI calculator cause your must be smarter than them. You are coming up with lies to defend a single type of insulation. How long is that ERV going to last ya? Air from INSIDE the house has toxins, outside air IS THE STANDARD FOR AIR IDIOT! VOC, indoor air pollutants, come from the inside, lets lock it in huh? ERV's stop working, no warning, and who will change the filter? Ooops
@HomeEnergyNow If you are a builder, then you are the worst in the world and I pity your poor customers. Of course outside air is filled with pollutants, dumb ass. It's time to refer to Samuel Clemens who said "Don't argue with idiots because..." NextGenHome is smart to let you run your fool mouth off so everyone can see what stupid backwoods builders like you know... NOTHING! I'll bet you're a smoker, too; just keep breathing all those toxins and particulates. I'll be pissing on your grave.
Indoor air is worse than outside air, outdoor air is the ASHREA standard for air. Filters don't stop smoke, or many outdoor pollutants. Idiot. Lets see your license #, OH SHIT!!! You just another foam video watching tool that has ZERO licensing, or education in the field(obviously). So you walk around outside with a HEPA filter on your head? Actually, moisture vapor doesn't have to leave with air, that is why DOE recommends AGAINST vapor barriers, moisture diffuses through the walls and ceiling
@HomeEnergyNow Thanks for letting us know who you are... Your statements are from biased data provided and codes developed by the fiberglass industry! Going into fiberglass remediation - so you're encouraging people to put it into buildings now? 68% of energy is wasted by air infiltration (convection), the rest is via conductive loss in structural members. Fiberglass is carcinogenic and cellulose is ACTUAL garbage which allow toxic particulates into your lungs where you spend 80% of your time!
Certainteed fiberglass is rated for IAQ, certified for it too. LEARN HOW TO CALCULATE BTU LOADS. There is no bias, I don't care if it is fiberglass or cellulose, or mineral wool, or cotton. 68% of energy is to air infiltration? TOTAL HEATING AND COOLING ONLY TAKE @40%!!! Knucklehead. Foam does NOT eliminate the NEED for fresh air. Foam houses are required to have a hole poked in them so that your HVAC sucks outside air straight in, ZERO energy difference using infiltration. Better R with loose
@HomeEnergyNow You're using the wrong software and methods to calculate your loads in an air-sealed house. Used to be's don't count anymore... and yes, once you air seal a building properly, 68% or more of the heating and utility costs are due to air infiltration. Obviously you want to build leaky houses because it costs too much to build them right? Wrong. Can you build a house too tight? Can you build a submarine too tight? Admit that you're wrong! Fresh air should be properly filtered.
Your 68% is retarded. Period. It costs peanuts to seal a home tighter than a foam home. You are obviously not a builder, lets keep this simple. If every home in the U.S.was super tight, and relied on a moving part AND a clean filter to bring required fresh air w/ single easily disturbed air intake, how many would be safe today?:1/1000? There you go, mechanical ventilation is NOT RELIABLE. Passive ventilation is 100% foolproof, and will last the life of the home. 99.999% of builders go passive
ASHREA is the one that creates all of the HVAC standards. And trust me, they are up to date. I guess if fresh air should be filtered, you must walk around with a big ol HEPA filter on your head huh? Filtering outdoor air has been found to actually increase the amount of allergies people have. VOC's are the indoor toxin behind the .35ach ASHREA standard, and guess what, no filter stops VOC's or toxic gases. What happens when Gma shuts a vent in babies room in a tight house? NO FRESH AIR. Oops!
ASHREA, BPI, RESNET, DOE......None of those groups are biased. They all have software or methods of finding the energy demand of any home. Foam will perform the worst on every single energy calculator. Just try it, please, so that you will shut up and realize you are talking to a licensed veteran of the feild with no bias. Foam is like putting a stupid stamp and your forehead and people seem to enjoy that. Resnet and DOE both have free trials.....go ahead, try it out, POST YOUR RESULTS!!!!
@sagane License #CAN06347, I am the industry. Go ahead and fill out a manual J, one with foam, one with R-60 anything. Tell me which one has a smaller btu load? Please learn the manual J before you show off your ignorance to the world. You should buy a foam rig, I have never seen as many going out of business sales as I do now! LOL You can be the next dreamer selling your foam rig. If you want into the home energy business.....you might want to educate yourself first. BPI, HERS, LEED anything
i've seen your propaganda on several foam videos. You are obviously biased, let me guess, you sell fiberglass. Or are paid by someone who does. You should focus on improving the image of your product and stop trying to hurt that of others. Yes, I am biased, I've had three types in my home, foam being the last of course. Reply and I'll send you copies of my power bill, and if you still conduct business in this matter I'll buy a foam rig and put you out of business, it's inevitable
@saganemc2 I don't sell insulation, I build 30+ homes a year, I am licensed in buiding performance and HVAC, I like fiberglass and cellulose, and mineral wool. They all go to R-60. Foam is a 40+year old failure, using spray foams is proof of lack of ability to do math, maybe ignorance or pure stupidity. There is no if and or but's, no respectable builder I know would ever use foam again. Risk no fresh air, don't think so, uses more energy conditioning the attic, is subpar to R-60. Why use it?

You don't risk occupant health, you don't risk occupant health, you don't risk occupant health, why don't you understand that? ERV's are rarely insatalled right, when they are, they don't last. IAQ hinges on a fan motor made in indonesia, no thanks.You cant understand if you don't build homes you are just extreme ignorant

ERV:
1:Cant shut a register, you won't get fresh air.
2: Who did the math to make sure the ERV what set right? I wouldnt trust them!
3: Dirty filter, no not that one, you need a tool to get into that black box, then you need to special order a filter, then you need to install it and hope it will last more than a few months at that price.
4: Neighbor thought they were helping with wasps, and sprayed pesticide on my air intake...OOPS.
5: People I know w/ERV's use their windows ALOT! LOL

I love how 99% of the houses in this country haver fiberglass insulation, yet a few are still so stupid they will believe it is harmful somehow.

@HomeEnergyNow It is rare to see someone SO biased who claims to be UNBIASED. Go on denying the facts. 80+% of the insurance claims and problems with buildings are in their porous envelopes. Air penetration through the envelope carries toxins and particulates that you and your customers are ingesting and breathing. Air introduced into the envelope of an air-sealed building, tempered with an ERV and cleansed via a filtered mechanical system is infinitely healthier; saving 60%+ on energy costs...

@acversusdc I am a builder stupid, 80% is MOISTURE. Obviously you are the biased one here. You refuse to use a single ROI calculator cause your must be smarter than them. You are coming up with lies to defend a single type of insulation. How long is that ERV going to last ya? Air from INSIDE the house has toxins, outside air IS THE STANDARD FOR AIR IDIOT! VOC, indoor air pollutants, come from the inside, lets lock it in huh? ERV's stop working, no warning, and who will change the filter? Ooops

@HomeEnergyNow If you are a builder, then you are the worst in the world and I pity your poor customers. Of course outside air is filled with pollutants, dumb ass. It's time to refer to Samuel Clemens who said "Don't argue with idiots because..." NextGenHome is smart to let you run your fool mouth off so everyone can see what stupid backwoods builders like you know... NOTHING! I'll bet you're a smoker, too; just keep breathing all those toxins and particulates. I'll be pissing on your grave.

Indoor air is worse than outside air, outdoor air is the ASHREA standard for air. Filters don't stop smoke, or many outdoor pollutants. Idiot. Lets see your license #, OH SHIT!!! You just another foam video watching tool that has ZERO licensing, or education in the field(obviously). So you walk around outside with a HEPA filter on your head? Actually, moisture vapor doesn't have to leave with air, that is why DOE recommends AGAINST vapor barriers, moisture diffuses through the walls and ceiling

@HomeEnergyNow Thanks for letting us know who you are... Your statements are from biased data provided and codes developed by the fiberglass industry! Going into fiberglass remediation - so you're encouraging people to put it into buildings now? 68% of energy is wasted by air infiltration (convection), the rest is via conductive loss in structural members. Fiberglass is carcinogenic and cellulose is ACTUAL garbage which allow toxic particulates into your lungs where you spend 80% of your time!

Certainteed fiberglass is rated for IAQ, certified for it too. LEARN HOW TO CALCULATE BTU LOADS. There is no bias, I don't care if it is fiberglass or cellulose, or mineral wool, or cotton. 68% of energy is to air infiltration? TOTAL HEATING AND COOLING ONLY TAKE @40%!!! Knucklehead. Foam does NOT eliminate the NEED for fresh air. Foam houses are required to have a hole poked in them so that your HVAC sucks outside air straight in, ZERO energy difference using infiltration. Better R with loose

@HomeEnergyNow You're using the wrong software and methods to calculate your loads in an air-sealed house. Used to be's don't count anymore... and yes, once you air seal a building properly, 68% or more of the heating and utility costs are due to air infiltration. Obviously you want to build leaky houses because it costs too much to build them right? Wrong. Can you build a house too tight? Can you build a submarine too tight? Admit that you're wrong! Fresh air should be properly filtered.

Your 68% is retarded. Period. It costs peanuts to seal a home tighter than a foam home. You are obviously not a builder, lets keep this simple. If every home in the U.S.was super tight, and relied on a moving part AND a clean filter to bring required fresh air w/ single easily disturbed air intake, how many would be safe today?:1/1000? There you go, mechanical ventilation is NOT RELIABLE. Passive ventilation is 100% foolproof, and will last the life of the home. 99.999% of builders go passive

ASHREA is the one that creates all of the HVAC standards. And trust me, they are up to date. I guess if fresh air should be filtered, you must walk around with a big ol HEPA filter on your head huh? Filtering outdoor air has been found to actually increase the amount of allergies people have. VOC's are the indoor toxin behind the .35ach ASHREA standard, and guess what, no filter stops VOC's or toxic gases. What happens when Gma shuts a vent in babies room in a tight house? NO FRESH AIR. Oops!

ASHREA, BPI, RESNET, DOE......None of those groups are biased. They all have software or methods of finding the energy demand of any home. Foam will perform the worst on every single energy calculator. Just try it, please, so that you will shut up and realize you are talking to a licensed veteran of the feild with no bias. Foam is like putting a stupid stamp and your forehead and people seem to enjoy that. Resnet and DOE both have free trials.....go ahead, try it out, POST YOUR RESULTS!!!!

@HomeEnergyNow step aside, or change your incorrect mindset and join an industry of the future. You are the asbestos of the 21st century.

@sagane License #CAN06347, I am the industry. Go ahead and fill out a manual J, one with foam, one with R-60 anything. Tell me which one has a smaller btu load? Please learn the manual J before you show off your ignorance to the world. You should buy a foam rig, I have never seen as many going out of business sales as I do now! LOL You can be the next dreamer selling your foam rig. If you want into the home energy business.....you might want to educate yourself first. BPI, HERS, LEED anything

i've seen your propaganda on several foam videos. You are obviously biased, let me guess, you sell fiberglass. Or are paid by someone who does. You should focus on improving the image of your product and stop trying to hurt that of others. Yes, I am biased, I've had three types in my home, foam being the last of course. Reply and I'll send you copies of my power bill, and if you still conduct business in this matter I'll buy a foam rig and put you out of business, it's inevitable

@saganemc2 I don't sell insulation, I build 30+ homes a year, I am licensed in buiding performance and HVAC, I like fiberglass and cellulose, and mineral wool. They all go to R-60. Foam is a 40+year old failure, using spray foams is proof of lack of ability to do math, maybe ignorance or pure stupidity. There is no if and or but's, no respectable builder I know would ever use foam again. Risk no fresh air, don't think so, uses more energy conditioning the attic, is subpar to R-60. Why use it?

Allergens? VOC's and indoor air pollutants are far more dangerous, sealing them in better is not improving Indoor Air Quality.
