As the owner of a steel building I can tell you that spray foam has a fantastic use not mentioned in this video, sound dampening! I had the ceiling of my shop sprayed and it cut the sound from rain to almost nothing.
Good point Joe! You are right, spray foam can greatly reduce sound transmission.
Thanks captain obvious.
Thanks. I was curious whether the ceiling could be spray foamed.
@@jimmarchman yes of course
Would that help water proof the roof
The applicator is knowledgeable in the application of this product, the surface finish and the condition of the whip hose tell me that. I have been spray foaming closed cell foam in northern Alberta Canada for just under 7 years and it is nice to see a well done job.
Thank you!
Houston Bros are great guys with a great product. They sprayed my attic space after I took out all of the batting and blown insulation that was making us sick. We were out of the house for only two days after with a slight "vanilla" odor that was completely gone the following day. Our heating/cooling costs reduced 30-40%, air quality inside the home is fantastic, less dust and the outside noise was greatly reduced. Call Tom and his two (working) brothers. They will be doing my new metal garage as soon as it's up in the next few weeks.
Thank you Wes, we appreciate the business!
Great service! Great price. 5 Star service. Very knowledgeable and quick to respond. If you are looking to have work done, look no further than Huston Bros. Thanks guys!!!
When you pay to have spray foam installed this is the quality you want! Great vid!
That was a good video. Good spray guy. Nice technique with the gun and checking with the depth gauge. I would definitely want to have this done when I build a pole barn
Looks GREAT and I bet it does an amazing job of sealing/sound proofing/ and insulating for heat and A/C !! I'm looking into putting up one of these building in the near future, glad I watched this vid !! Pay NO ATTENTION to the key board, do nothing, self proclaimed experts on here .... lol.
Thank you.
Appreciate the video. I work remotely for the former PlyGem in Rocky Mount.
WOW DAMN, VERY IMPRESSIVE....
AND WHEN (DRIED/HARDENED)
IT LOOKED LIKE A (CEMENT) WALL,
READY FOR SOME PAINT 🎨 ......

I am a big believer in closed cell spray foam for many applications. From my experience, the downside to applying spray foam directly to the backside of the exterior metal panel is the struggle this will cause if you ever need to replace that panel due to damage caused by storms, bikes or cars, or someone with an attitude kicking the siding. The struggle to replace the panel is even worse if the inside of the building has been finished off with metal liner panel or plywood because you can't get to the backside of that panel you are replacing to cut the spray foam at a joint to allow for its removal. During construction of your building, if you do plan to use spray foam, consider placing a house wrap before applying the metal. The foam will adhere to the wrap, not to the metal, allowing panels to someday be replaced if damaged.
This will cause condensation
Terrible idea 😂
NO, NO, NO, this will cause condensation between the steel and the house wrap, do not do this. My buildings have been up for 50 years, and nobody has ever run into them.
I researched this a lot and just had a 26 x 42 metal horse barn sprayed . We are going to be using it as a home . The foam worked great and made the metal structure solid as brick ..
Benny Bryant, I’m looking at doing this to a building roughly the same size. How much did it run you to have this done?
Made it quieter too didn't it?
I have been wondering if this has been done successfully.
Benny Bryant: Hardy as strong as a brick. Maybe stopped the ‘oil canning’ effect but not much strength added. I’m not an engineer, but my neighbor has a brother in law that knows a guy that grew up with a friend that went to school to eventually become one.
Benny Bryant any issues with off gas being put off? I am looking at buying a metal arch building but struggling to settle on a insulation for the metal building.
Damn this foam looks way way better then so many I have seen. Great job.
I did 1 1/2 rockwool between purlin horizontal and used 3m Spray adhesive to hold in place.with 6 inch of Rockwool between wall framing,vapor barrier and log siding, on inside.
Underside of roof pan, had 6 inches of closed cell and cedar T&G cieling.
I did it...made a flimsy metal building into an actual solid building. Good stuff
Awesome! Closed cell foam is a structural foam and can add a lot of racking strength to walls.
Houston Bros could you put a video up of some previous metal building that have been foamed 10 years or more ago to show that there is nothing wrong with the building? Would be nice to see how the building is holding up thanks.
This would be an interesting endeavor as we have been spraying foam for over a decade and I would like to go back and see how some of our older projects have stood up to the test of time. Usually foam turns darker in color but that's about it. It's pretty permanent and really should not change much at all over the life of the building. I have rarely had a client contact us with any issues after installation. You can see many more of our metal building projects here www.houstonbrosfoam.com/metal-buildings
@@HoustonBrosSprayFoamFerrum Mostly im curious about rust on unpainted steel.
So satisfying to watch. Wish it covered the whole process. Great videos!
You can see more here at our website: www.houstonbrosfoam.com/metal-buildings
You guys do really nice work, good to see
i was in dmz korea in the mid 90s and most our bldgs were 50s quanset huts. they had been sprayed 'on the outside' with foam, very thick. worked great in winter. also in summer.
Why spray on the outside the building why not inside
What is the average price per square foot for close cell foam? Great video
Spray foam really does work pretty good. The problem is the cost . For the same or a little less price I can bubble wrap my garage and insulate it with faced fiberglass. It’s unbelievable wha some of these guys charges here in southern Ohio. I’ve had the floor of a small house insulated awhile back. It was 28x40. Estimateswas $1500 to $1800 . I had half that in the fiberglass
And I thought you were out of Houston Texas 🤦🏻♂️ good video guys 💯
We get that a lot! I have had to turn away many Texans.
@@HoustonBrosSprayFoamFerrum Bummer... Was just about to check your site.
I have a building that needs to be done right now. I live in Greenville S.C., let me know when you can swing by for my free estimate! Haha, just kiddin. Great video. Had a few buddies recommend this and now I’ve made my mind up. Godbless
Great info, thanks I am planning a building and needed this info.
Great to hear! If you need more information please check out our website: www.HoustonBrosFoam.com
Wish you were closer to the Abilene area. I am looking to have my building done exactly like that.
Check out the sprayer's attention to detail.
I just had an estimate for my arch steel building, it came in at $17,500....so I bought my own Chinese spray unit for $3,700 and had 4 55-gallon barrels delivered and I'm going to spray my own building for less than $10,000 and then my other building as well.
Do you prime the galvanized steel first?
Spray Jones says from test that 2" is best to stop enough heat transfer which will cause condensation and is all you need to insulate almost anywhere in the states. Did you find 1.5 enough?
I'm actually putting up a 18 x 22 metal garage up at my Basecamp in northern Wisconsin
Texas sun. Would you recommend 2 in on walls and 3 or 4 on the ceiling? Or would 2 inch be enough on the ceiling?
You want to have at least a 2-inch layer.
One you do closed cell should you have any condensation issues?
Should I run electrical wire first?
would this work if the metal shed was for welding purposes ? does this foam burn much ?
Real nice. Makes it tough against wind damage too. But if some siding gets damaged by oops tractor impact and i want to repair 7 sheets...
Simple .... no dwi :D
You should house wrap the building and spray the foam on that. Then it's no big deal.
Why is all the foam around me yellow? This Looks great! Wanna load up and come up to montana?
Nice video, I'm an architect in Michigan and I spec nothing but closed cell spray foam in all of my commercial projects. Lately, we have been told by metal building companies if spray foam is applied directly to the metal panels it will void the warranty of the panels. I'm not sure why, any ideas? Have you heard of this?
The thought or worry is that foam is applied in high humidity trapping water between the closed cell and steel eventually causing rust
Hey Tom, i'd call you to get a quote but I'm in Australia so that wouldn't quite work. Question ; can you put this same product on the roof as well as the walls? EDIT : never mind just looked at your website for metal buildings, first picture that came up. Keep up the good work mate.
Will the spray foam delaminate from the steel? The metal has a large thermal expansion coefficient.
I have put spray foam on a number of houses. Curious how you could wall board this job if you wanted since the metal studs are now covered?
What kind of foam is that and about what did it cost to spray this building?
This is a plural component 2lb closed cell polyurethane foam. It's about r-7 per inch and is a moisture, vapor, and air barrier.
I don't recall what it cost to spray this project. Projects can range in price from $1,000 to $10,000. Pricing can vary depending on a lot of factors like:
>Total square footage
>Type of corrugation
>Type of foam sprayed
>Thickness of the foam sprayed
>How far away the client is
>Will a lift be required
>How much preparation (plastic and masking) is required
>How many doors and windows
>Will the foam need to be cleaned off of the studs
It's not an easy answer. This is why we do free estimates so we can give you a custom price for your project. I hope this helps!
@@HoustonBrosSprayFoamFerrum Duhh, that is an extremely easy question to answer, you got paid, what was the amount written on the check?
I had a company come in and spray he flushed out the 2x6 on the walls and gable. I did under the roof with batts.
difference with closed cell and open??? one for up north and the other for down south?????
metal buildings expand and contract with outside temperatures. how is that possible once foamed ?
I am building Metal building in Northern Arizona. My insulation company bid one with open cell. Do I need to use a vapor barrier here? We rarely have humidity higher than 15% except in the monsoon season (4 months) when we can get in the 70% range at the most and not everyday. We get freezing temps and snow up here from Jan - March, as well. I hope that is enough info to get a good idea of the proper way to insulate up here. The wind is so bad here that it is almost impossible to put on the insulation from the metal garage companies. TIA
Would this be suitable for steel shipping containers ? Thanks
I am trying to find someone to do this to my 30x80x14 pole barn shop here in Indiana. Wish u was closer.
Looks great.
have metal porch cover ,screws stick thru n leak,porch issohot,canmy metal co er b spray foamed with the leaks.
Great video, Tom!
Thank you!
Does this foam burn
Can you spray about six inches on ?
Question. I have a new metal building planned for April. I will have natural gas heating and the horizontal vent pipe gets hot, how do spray foam companies manage this when spraying around the vent pipe?
i use to spray foam it is the best nice job boys
how would this be in a van conversion to a camper/ thanks in advance
After the foam is applied is it common to leave the walls like that? Or do most people put drywall or plywood or anything over the top of it?
How long does off gassing take? I've heard of some horror stories where in some cases it never stops off gassing, making people very sick!
What’s the name of the gun your using? We use a gun threw nitrosys and I hate the pattern that comes out of the tips. The tips constantly block up if you can’t move fast.
Is this better than the regular insulation you always see?
after the foam sprayed can you add rockwool for better insulation?
Why? More closed cell would be better..
Typically the SPF is so effective that additional insulation is not needed.
Mine sweats and it rains inside. How much does it cost to have an 16 x 16 ft building done?
What's the R value when your done?
What type of mini split or unit?
i put some in the corners of my chicken house to seal the metal ribs behind the corner posts to keep snakes out ,,,, long story short chickens love it and ate it all ...chickens never got sick,, just saying dont use it around chickes.....have a great day!
What about off gassing and the gasses that get released inside the building down the road .
Is that BAD for ur lungs???
Older formulae used to have that issue it they were mixed at the wrong ratio, applied too thick in one layer before it had to cure or applied at an improper temperature.
Newer formulae used today are not as sensitive to temperature and will cure even if applied thick.
They still need the correct mix ratios, but this being wrong can be detected almost immediately.
When using closed cell where you can see it and touch it, you can find any problems just by looking.
More expencive than we would have ever thought ! The guy is suposebably the cgeapest in our area and ihis estiment was 8 grand. The whole building with the cement was only 3 times that , And that was with a cemented lean to. We cant afford that as much as i like the stuff.
We would like to build a house next year and go with a cathedral ceiling (beams, t&g boards, then insulate the top). However, I just had a local contractor telling me he wants 7.5 CAD/sqaure foot for 5" insulation. Now that sound ridiculously expensive to me or is that normal?
You can buy the 10 gallon spray canisters with the built-in and gun from Home Depot. Save yourself $16,000. You could probably do this whole building yourself for 1500 bucks, 2000.
What is the R value you end up with? Thanks!
R-7 per inch applied
He makes the application look simple, but believe me it is not!! 2lb foam is perfect!!!!
Isn't off gassing a major issue in the summer?
No, off gassing only occurs during the first 24 hours. After that the foam is totally safe.
@@HoustonBrosSprayFoamFerrum That a relief! Not enough to worry about without 'off gassing'. It sound like me after a Mexican dinner!
Do you have to vent a metal building once you do this? If so how?
Hi, I’m in the process of getting my metal building done, 24x34x9 2 car doors entry, can you give me an idea how much $$$ I’m looking at for Closed cell insulation, thank you
I've heard that it's a good idea to pressure wash or somehow clean the metal panels before applying closed cell foam to remove manufacturing oils which might cause closed cell foam to pull away from the metal over time. Is that true? Planning on building a barndo here soon and would like to know the answer to that. Thanks! Nice video.
Check out Spray Jones. He’s another good source of information all things foam.
Does it off gas much after it's cured? Will it off-gas in the heat of the summer when the sun is baking the building?
Ty's Videos It will completely stop off gassing between 24-48 hours. The typical cure time. After that period, it will never off gas again
What is the cost average for a 40X60 metal building roof only?
Projects can range in price from $1,000 to $10,000. Pricing can vary depending on a lot of factors like:
>Total square footage
>Type of corrugation
>Type of foam sprayed
>Thickness of the foam sprayed
>How far away the client is
>Will a lift be required
>How much preparation (plastic and masking) is required
>How many doors and windows
>Will the foam need to be cleaned off of the studs
It's not an easy answer. This is why we do free estimates so we can give you a custom price for your project. I hope this helps!
What is the spray foam made of , cellulose or poliuretane? Is it safe, In the sense that It doesn't liberate poissoneous gases?
What is the typical cost for something like this?
My dad built a house can you spray foam? The people that bought it we're allergic to the foam gases, they had to tear out all the inside drywall and dig out the phone and replace with fiberglass insulation. Cost almost as much as the house. There's other video showing where if it's not put on proper the right temperatures are the benoliel shin isn't right? The guy had to tear his whole roof off and replace it. That was many years ago? That stuff turns rock hard I've never seen that.
great foam applications
Do you spray the center part of the roof where the 2 sheets meet my contractor had left a small opening there. With a seperate cap I'm assuming it was for ventilation. My spray foam guy covered that up it seems to trap all the heat inside now should I open it back up?
Wow great job!!!!
Thanks!
That had to make a huge difference.
Do they have companies in northwest Florida?
What is a cost on a 24x50 x 8' tall legs walls and ceiling?
great job nice and clean
Question is how much R value do you need? I live in NC and we some nights into the single digits. On these metal buildings if you get the insulation the seller offers you can only get 6 inches or R19. I am not sure that is enough in the roof, but unlike a pole barn you don't have the option to blow insulation in the attic. Seems like with this stuff you would have to put at least 2 1/2 to 3 inches to get the same r value.
It depends on what you mean by "need". There are code requirements for living spaces and commercial buildings. If your building isn't being lived in or subject to code then you can do whatever you like as far as thickness. R-value isn't as important as an air seal. Performance is vastly improved when you achieve an air seal. We have seen huge success with 1 1/2" -2" of closed cell foam. Clients report easily heating their spaces with with just 2" of closed cell in metal buildings.
The wire is supposed to be in conduit the first time a wire shorts the building will burn
It will trip the breaker
@@slopoke8656 BS reply ////////////////////
I'm buying a 30 by 30 foot building. The company charges about 5 grand for a mylar double stick insulation that has an R value 15. The building is in the desert so I imagine the reflective value of the foil may be better than foam. But it certainly won't stiffen the building. Should I use foam instead? Do you know what the R value of foam is? If I can afford it, can foam be sprayed over the foil insulation?
@@Drizimar1 The foam adds stiffness, which is a concern due to high winds in the area. But I assume the R value of the foam is less than 16. So since it's in the desert, which can reach temps of 120 in summer, should I go with foil instead of foam?
Can I do spray insulation BEFORE I run the electrical? I would rather do it that way so if in the future I need to get to any wires, I don't have to cut any foam to get there?
Yes, by electrical code, you can run all of your wiring on the inside of the building using conduit.
Additionally, it completely seals the interior envelope.
What kind of temp difference is it in summer? I wanna store plastic baits and other fishing gear in my big metal building. And was considering this. I will not have an AC or anything
Spray foam is a fantastic insulation product, but it cannot generate heat or cool, it can only maintain the internal temperatures of the building more efficiently. Think of it like a drink cooler. You will still need to add ice to make it cool, but the ice will melt slowly because of the insulation. With that said, many clients have reported back to us that their non-air conditioned metal building felt significantly cooler after the installation in the summer. If maintaining a specific temperature is critical then you will still need to consider installing a climate control system of some kind.
How long after application does the off gassing continue to produce fules?
Once the surface has hardened (takes minutes to go hard) then it's 100% safe and no gasses come from it, then the rest hardens over 24 hours and it's solid.
No more than 24 hours.
Is there future off-gassing that is toxic?
I wonder if it's flammable? I do a lot of welding.
It is plastic so it can burn, however It doesn't burn readily and can be covered with a fire barrier paint if need be.
i live in alabama....have a 40 x 60 12 feet high..........any idea of the cost...will not hold you to it...just a guess....thanks
Just saw your video , great job. Question I have is I had a metal building for 8 yrs and I insulated the crap out of it ceiling to floor but every year when it was damp out it was so wet inside looked like someone soaked insulation , I had no vents at all and beleive that was the issue , I have since moved to new property and want to install same building but don't want the moisture will the spray foam take care of that or do I need ceiling or gable vents?
Thanks for info
I think you need a vapor barrier.
Closed cell spray foam insulation is a moisture barrier. As for needing vents, that depends on what you plan to use the space for. Since it is closed cell, air can't pass through, so highly volatile chemicals will build up in the space if not properly vented.
Any recommendations for a company in San Antonio Texas area?
How much does it cost for a shed this size?
Awesome job
Love it
Thank you!
