Thanks for sharing your experience. I have a metal garage similar to yours except smaller. And I watched about 20 videos on insulating one of them and have seen about 12 different methods. Each method seems to have its pros and cons. I hope you are satisfied with the results.
You are losing over half of the R factor by not having the foil face the metal to radiate the heat back and also you need a 1/2” gap for even a higher at factor. But overall it looks great
most spray adhesives will delaminate with high heat. that's 3m super 77? that's why we don't use it for upholstery unless we want a temporary glue joint. We either use weld wood contact adhesive or Alpha adhesive. but I think those would attack the foam
It’s doing it’s job good enough lol the building holds heat really well and the ac got it down to 75 when it was in the 90s outside, now granted it takes about an hour to 2 hours to get it to cool down but for what it cost I think it’s good, I called for spray foam and they quoted me 6500$ so that option was out lol
What part of the content do you live in I am in the South East hot swampy summer mid to (90’s with high humidity)mild cold winters 30’s to 40’s. Are you in the same climate?
Yes I’m in sc near the beach, the humidity is the biggest problem, the ac keeps the building around 78-80 mid summer heat which feels like a fridge compared to the 90s and humid outside lol
@@hodgepodgegarage3911awesome I am in GA so similar climates. I appreciate you posting this video. I have been debating between saving for spray foam or try foam boards.
@@hodgepodgegarage3911 do you feel a bigger AC unit would bring the temp down further, I guess I am asking do you have an undersized minisplit. Or would a dual zone mini split work better. I could something similar to what you did (foam insulation and minisplit) it would still be cheaper then sprayfoam alone. I was looking at buying 2" foam boards they are $25 a board.
@@markfayerman1206 This will depend a lot on how you plan to condition the space. For a garage where you will have it unconditioned most of the time, but turn on AC when you walk in and are in there a bigger unit will cool it faster when it's running. If you wanted to keep the building conditioned most or all of the time then investing in more substantial insulation would give better returns than a bigger unit, also keeping in mind that a bigger unit will use more power and raise your power bill if you plan on having it running all the time.
@@hodgepodgegarage3911 It must not get that hot there. I live where it's 100+ on some days, that unit you installed wouldn't even keep a small garage cool. Your shop looks great.
The roll up doors let lots of heat in. Insulated sectional doors would be much better. But metal buildings are not easy to cool if they have no shade and are in hot climates.
According to everything I've ever read about insulation, apparently the thermal bridge that is created from your support poles pretty much negates any R value that this insulation may afford. Look it up.
The support poles' surface area is tiny compared to the walls, so the insulation has a great effect. But covering the poles would also make a difference.
@@hodgepodgegarage3911 thanks for the update man! I’ve been wanting to do this with mine too, is it working pretty good? Notice big differences? You should make an update video when you have time!
@@tmontel2116 it works good for what it is, it’s only 1/2” insulation and I k ew when I installed it it wasn’t gonna be a refrigerator in there but that mini split unit I have says it heats up to I think 1500ft2 and in the summer at like 95 outside it will keep the inside in the high 70s which is all I can ask for from it! I was thinking about doing an update now I have the addition to the garage that’s uninsulated, might make a video comparing the 2 without the ac on
@@tmontel2116 oh yeah it stays warm easier than cool, the metal Building is pretty good about holding heat! And that mini split unit has a good heater!
I thought the silver side was supposed to face the metal so it can block the metal from radiating heat

Isn’t there supposed to be a gap between the metal walls and insulation ?
And isn’t the foil supposed to face the wall ?
Simple rule of thumb...Foil faces where you want to keep the heat
most spray adhesives will delaminate with high heat. that's 3m super 77? that's why we don't use it for upholstery unless we want a temporary glue joint. We either use weld wood contact adhesive or Alpha adhesive. but I think those would attack the foam
With only 1/2 in foam, did it do what you wanted for cooling and heating?

Did your insulation stay up. I’ve tried several gluing adhesive. Finally used furring strips
Nice but you put the board up backwards .
Always let builders install the double bubble on roof as it's built !!!
I see the Firebird... I have a 95 Trans Am 👍
what size building and how much did that all cost?

@@markfayerman1206 I’m sure spray foam is better but the cheapest quote I got was 7k for spray foam so that was out of the question

If you're in a hot location you would need about four of those AC units for the shop, even with your insulation.
I’ve already thought about adding another it take about 3 hours for it to cool down in the summer

What size is your mini split? Was it enough for the square feet?
What size if your building and how many total sheets did you use?
The building is a 24x40 12 high I honestly couldn’t tell you I want to say it was about 90 sheets somewhere around that
Why not overlay the insulation boards under the metal siding?
Much simpler and efficient.
I used 2” in between then went over the frame with 1/2” because the frame is metal and radiates cold or heat
flip all the boards. go over the bracing on the ceiling not under the lip. other than that looks good. hope to see the finish
What size is your metal shed
How big is the mini split that you installed
I don’t remember exactly I believe it’s a 2 ton? Said it was good up to 1500 square feet
I just bought a 24k BTU for my garage like yours. To bad that I can't load pick,s of my garage how I insulated it

Any condensation issues so far?
None that I’ve noticed, the concrete has a plastic moisture barrier under it and I spray foamed all the cracks I could find before insulating it

@@tmontel2116 oh yeah it stays warm easier than cool, the metal

Not much r factor in that insulation
A lot more than the steel siding lol, also super helped with the echo in there!
I have vertigo please stop
UPSIDE DOWN
Listen I made a mistake with the first 2 and it was too late at that point lol
