Yeah this little experiment proved exactly nothing... Would've got the same results with just a 5 inch air gap and another layer of plywood on the inside lol
I was actually thinking the inside temperature would have been way cooler. I still think spray foam is a nightmare for any electrical work and or future renovations.
You got to acknowledge that there are no doors so the heat is entering the inside environment but imagine once it gets doors and Ac unit how much cooler it will be
The building I’m in was owned by an insulation company. All fiberglass, and some of the inside walls aren’t even sheathed. Eight inches of insulation, pole barn over a concrete floor. It stays below 80 on the hottest of days. So, we keep the doors closed when it’s hot.
I thought open cell would condensate against the sheet metal... I had 1" of closed cell sprayed in my container house. Wish I did 2" but I'm a poor boy. Lol
I work in HVAC and I love foamed houses, the attics are always in the 70s some people even condition the attic! Money well spent, the energy savings are great and it's always an icebox inside
@@airgliderz when the "surface" is beyond the measurable capability of the $15 gun it 100% just picks up the collective density of which it's passing through.
Still think it's easier to just set the building further into the ground and into a hill. My dad did that with his house the first story and the basement stays cool no matter how hot it is
That's totally wrong how you did that test. The outside siding is that temperature because the sun is heating it up. Go do it on the north side where the sun is not cooking the steel.
He's showing the difference between the hot steel and inside. Not the cooler steel and inside. If there was no insulation, it would be hot steel on both sides.
Take the readings at 1pm. And then insert a thermometer in the foam and take the readings. Foam is great but it will also absorb and hold heat if the inside envelope is not cooled properly and ventilated good luck on the build.
As a 40 year builder, I have found the best results are from rigid foam insulation sheets above the sheathing with perlins spacing the metal from the insulation. Finish it off inside with flash & batt (1" close cell spray & rockwool). You won't even know when it's hailing...
The problem with this foam insulation installation is it should never have been in direct contact with exterior sheeting. You need at least a 1" air gap with radiant barrier facing out on foam. This would reflect most of the heat from outside and allow the foam not to heat from conduction.
I live san jose strong sun..I use foil backed foam on windows.. from articles reflects thermal radiation.. so 110 on window side 76/78 on inside of foam.. plus no thermal heating of room.. my bath.. kitchen no longer heat up. I also use at bedroom wide window to stop sun glare on tv and blocker curtains.room never heats up.. aluminum side out reflects solar radiation..I use blinds then foam sheets then curtains.. kitchen I made a foam valance covered in a curtain a foam panel undercut goes into openning..winter summer hugh difference.. no one sees foil backed foam.. I did a joke one for bathroom summer sun was brutal room heated up walls etc.. I used flat packing foam taped together to fit into window recess..then used aluminum foil shiny side out as a tester.. damn it really worked.. I still use it.. the room wont heat up..I tested on and off..hugh difference I mean hugh.. try it on a lark... it's up right now.. I even have new thermlpanes but one must stop suns radiant heat.. only sunny windows the rest just thermal sun block curtains.. just try in a sunny hot room ..you will be amazed.. great for a tv room darkens room like a movie theater. It doesnt have to be tight loose is fine..it reflects solar radiation.. aluminum is one of best reflectors of heat from sun..homes here now on roofing use foil sided sheathing.. think if suns. Heat Doesnt enter room and heat items up how cooler you would be..
If you're going to have an attic, if you were to leave an open area where you could see the roof at all times, you could put in a solar chimney and inside that building it would be about 75° to 70°
I was helping my brother a few weeks ago with a new property he bought, we gutted the whole thing and had the property spray foamed. The temperature inside during peak summer after being spray foamed went down 20°, after sheetrock it went down another 5°
Spray foam rocks. Just make sure it's applied correctly. Temp at application time is crucial. Live in the North East. My out building that houses all my water tank and treatment used to require heat tape and heat . Now is heated by the well water itself. Initial cost was expensive but it's more than paid for itself in utility costs and aggravation of frozen pipes and the worry of fire by faulty heat tape or heater. Nothing worse than the missus waking you up at 4 am to go thaw pipes because she's got to put her eyeballs on before going to work. (We were working opposite shifts, so don't get in a tizzy)
Ceramic white paint should be law in Texas, and for flat roofs, expanded concrete on foam pavers, they use in Alaska to keep the heat inside. Then solar panels to run the A/C. Done.
thats actually the point! To show the difference in heat on the same wall. The reason for the difference is the insulation, which is the point of the video. To show this difference.
Should have purchased a light colored steel siding. I had black shingles on my house and when temps were above 90 i could never get my AC set points to match, couldn't keep up. I purchased light grey metal roofing and it was like we upgraded the entire AC system, never had a problem with it again, had nothing to do with insulation in the attic, because there isn't one in my 1926 craftsman home, just 2x6 with rock wool and plywood.
I had a metal roof that was getting so hot it would melt the wire insulation on the inside, and it was way too hot to even touch. I painted the outside with white elastomeric silicone paint, and now I can hold my hand on the inside in direct sun, and no more melted wires. I imagine it would be even more effective with insulation.
How are you doing the HVAC there. Here in Texas I see so many foam building and homes like that and they don’t put the right HVAC system in and make the place unlivable. I love the foam but so many people don’t think ahead on the HVAC side. Then don’t get a unit with dehumidification or the right size system for the house. Load calculations are very important on a foam house.
Go back at midnight and measure the difference. Spray foam is a insulator that holds heat pretty well. So while it keeps heat out it also will keep it warmer for longer.
There is no doubt spray foam is an excellent insulator but do your research before having it installed. Most reputable pest control companies will NOT issue a termite warranty if you have spray form because it holds moisture and termites eat it. Second issue, if you were to get a roof or plumbing leak it could be months before it was discovered because the foam absorbs the moisture and hides the leak. That being said in certain colder, low humidity climates where termites are not an issue the R-Value spray form provides is impressive.
You did great mike. The heat rises. I did the same as you. In Texas. 40 by 90 metal building. 2 inches closed cell everywhere Then 6 inches open cell on roof and r19 fiberglass on top. Whole house dehumidifier and 3 ton AC. The way to roll
You’d have it so much cooler in there if the outside wasn’t black… like paint it with white or silver paint. But black is just gonna cook you n absorbs so much heat from the sun like place a white painted metal piece in the sun to see how much difference it makes. It’s probably gonna be 50°f difference already
Makes you wish you went with white now . Had that same discussion with my wife when I was building my 50x60 shop. Might be 110 outside, without insulation it's in the 90's.
The open cell foam will be his downfall. It's very pourise and doesn't block out moisture it absorbs it. 3 inch of closed cell would have kept it in the 90s without being conditioned. Plus closed cell adds rigidity to the building. Meaning the building is stronger and heavier with the closed cell.
It will make a big difference if you intend to drywall and tape all that up. Then you can run a small AC unit and the building will retain the cool air better. Vice versa in the winter in regards to heat.
definitely should of did 2 or 3 inches of closed cell or 5 plus of open cell. 1 inch is not sufficient enough for a conditioned space. maybe in a shop to bring down the radiant heat off of the metal. so now to have r7 on roof which is a no and and r 19 on the walls. with spray foam 50 percent of the efficiency is in the roof deck and 30 percent is in the walls over conventional insulation.
But you have to attach a metal plate on the foam surface. The light and electromagnetic energy refractory period is different. It needs a condensator/ energy storage
You can compensate by changing your emissivity rating, Styrofoam insulation is 0.60, but this idiot took both readings with the same E rating of 0.95. He is just spreading lies on the internet.
With no air-conditioning in the building and open to the outside air both sides of the ceiling and roof should be the same ambient temperature minus direct the solar load
2" of Styrofoam insulboard at least 4 feet wide around the inside circumference of your floor will make a huge difference as well. Put it down, then your substrate, reinforcement and then concrete. Isolate your concrete floor from the outside footings with a rubber expansion strip. Should hold about 60°F year around in the center of the floor. Easy to maintain inside ambient with the walls and ceilings that thick and tight. You made a giant cooler. I think 2" spray foam closed cell is like R72 in value. Heat with a candle, cool with an ice cube. Proper insulation always pays you back.
The sun doesn't look like it's been up long enough to fully thermally heat soak the foam. Do it again after high noon. But it does work great, love the open cell foam insulation nice tight homes nowadays.
While this tip is too late for this guy, if you want to do a metal skin building always add a thermal break between the metal and the studs. I typically spec a horizontal Z-channel/Z-furring with a thermal break. All of your mechanical fasteners, transfer hear from one material to the next, if you use a proper thermal break you can significantly reduce that temperature even further... also closing the doors and windows will help too.
messur a black panel in direct sun, but I can do you one better Rockwool do a demo where they take a gas torch to the back of a think 100mm run og for a couple of minutes, the back is glowing red but front stil cool enough to toutch. And it handles that torch for a long time before it burns through, if memory serves me right about 30 min of what 7-800 C. That's impressive.
There's a pretty big error on those guns when measuring the temperature of different surfaces. You'd probably be just as accurate putting your hand on the surface and saying "hot" .. "warm".
It’s Texas. What do you expect? Lol “let’s add insulation to prevent heat from coming in and then let’s paint the building black so that it absorbs the maximum amount of solar radiation.”
Black is actually the absence of color (light). We see red, green, blue. The three together makes white. Also the reflectivity of the material makes more of a difference. Dark and shiny reflects better than light and matte
Man I wish u would've give me a call before u sprayed foam it differently works as a great insulation but man be having alot of problem with it Corroding and rusting out with in a couple of years because of Condensation in-between foam and metal
A black surface will measure hotter than a white surface with an IR thermometer. Your thermometer is measuring the amount of emitted radiation and every material is vastly different. You need a contact pyrometer to actually see the actual difference in temperature
The uk not long had a 40c plus day. Last month and a national drought. Very unusual for our climet. No chance for our bodies to adjust as it came to use in an instant then it was gone. I believe it was 104-109f. That was hot with no ac in our homes.
The surfaces have to be close to the same color to compare ir temp. Black radiates better than white. Stick a piece of black duct tape on the inside and see how much of a difference it makes. I don't know what the difference will be, only that there is one.
Lmao as one of the biggest builders in Texas I at one time sold this product. Then one day I had a leak in a million dollar house. You figure out the rest. That’s not the only problem I had with foam, if the chemicals are not mixed properly it can be hazardous.
With the door wide open your foam should be the same temp as the outside air temp. Not sure what you're trying to test here other than black things in the sun get hotter than the air temp.
Would be cool to see the same test done when it is finished and has some hvac in there. Even just with doors and windows closed st the air temp isn't showing up on the inside.
Interestingly, so many people who don't know much are telling him he should have chosen another color when it's not your building. It's his choice not ours
Damn this really shows how well the sun is at heating up black surfaces. Good job little buddy.
Ha ha yeah maybe they should have thought about painting the outside white as a more cost effective way to reduce the temperature inside 😅
Yeah this little experiment proved exactly nothing... Would've got the same results with just a 5 inch air gap and another layer of plywood on the inside lol
If you want to experiment with having a white reflective exterior - paint some
CHALK PAINT on the black stuff . The
difference will be HUGE.
It ain't easy being trendy!
I don’t get it-it’s 100°F outside and 110°F inside the building. There’s no temperature relief for someone working inside the building.
Since you double framed it, you should have integrated an air gap.
I was actually thinking the inside temperature would have been way cooler. I still think spray foam is a nightmare for any electrical work and or future renovations.
You got to acknowledge that there are no doors so the heat is entering the inside environment but imagine once it gets doors and Ac unit how much cooler it will be

It's not finished so no air conditioning inside
Well, it's not going to be cooler than the outdoor temperature, that's for sure. It's not rocket science!
And thats with open doors and all true it makes a huge difference.
Thanks. Really shows how good closed cell is. Its more expensive but 1" performing almost as good as 5.5" of open cell is impressive.
And the same cost. 1” of closed is the same cost as 5.5” of open.
So you're saying 1 inch can be a good thing after all?
I thought open cell would condensate against the sheet metal... I had 1" of closed cell sprayed in my container house. Wish I did 2" but I'm a poor boy. Lol

Did you remember to adjust your emissivity?

The ambient temperature is what you should be measuring. NOT surface temps.

Just curious why you'd use black rather than a more reflective color if you're worried about heat?
With the door wide open your foam should be the same temp as the outside air temp. Not sure what you're trying to test here other than black things in the sun get hotter than the air temp.
Would be cool to see the same test done when it is finished and has some hvac in there. Even just with doors and windows closed st the air temp isn't showing up on the inside.
That would be a test if the HVAC system. It would be literally whatever temp the thermostat is set at
@@ryanstreckfuss9590 I will give you a chance to think about how that statement is incorrect before telling you why it is incorrect.
Nice next time use a light color inside of black to reflect the heat so it would be even cooler
But it's his property. Maybe he likes it black.
Paint the building white. Would stay much cooler
You'd get 98 degrees with no insulation using reflective underlayment and a vented45° batten system.
I need to know how much spray foam I need to keep it at 70°F!!!
100 is still too hot.
This response shows you don't understand heat ;)
@@ryanstreckfuss9590 It was a joke
Color makes a difference with that type of Temp reader
Black metal in Texas smart choice. If it was white it would be 50 degrees cooler to start with.
Interestingly, so many people who don't know much are telling him he should have chosen another color when it's not your building. It's his choice not ours
Funny thing is people in arizona think it's hotter there than In Texas that 100 with humidity is like 115 real feel
For a second this guy looked like an old Aaron Rodgers
With your doors open it will be base 100 on all surfaces inside if its 100 outside.
