This is completely false. Nowhere on that link does it say anything at all about Mylar. Your link refers to a broad category of plastic films used in a wide variety of applications, some of which may or may not include Mylar, but none of which are specifically identified in your article. As you say yourself in the thread's opening post, Mylar is a specific type of plastic sheeting developed by Dupont, so you do know the difference. Here, read your own link -
Read Dupont's own material safety sheets. They clearly state: "metallized mylar(PET, a plastic, fiber) may support combustion". Normal Al foils don't support flame or combustion.
How many people here use automotive window tinting as reflective material in their grow rooms? None, right?
This is a piece of promotional material put out by a company to sell their insulating product
Let me stop you right there. It's
merely one example.
; of course they're going to brag it up by making the most favorable comparisons possible between that and whatever competing product they can find.
I agree, to an extent.
The fact that they don't even specify which particular product they're comparing themselves to ought to raise a red flag right off the bat
Because it really doesn't matter. The plastics used in these fibers melt much lower than aluminum coating itself. They also support flame, and produce noxious fumes(smoke) when they do. Try it, outside!
, and the fact that they offer no substantiation of their comparison -
Grains of sand. Get enough on them and you could make yourself a beach!
and don't even say what testing methods were employed - makes their promotional material worthless in this discussion.
Now start refuting the evidence from PhD's and experts in their fields.
I can call myself a unicorn if i want
Ok, you're a unicorn.
, and put up a website claiming that I've been tested and found to be a unicorn.
OK! You're a unicorn.
But that doesn't mean my website would be valid evidence in an argument about the existence of unicorns.
I still believe you're a unicorn.
I'm sorry to say this, but this is a perfect example of why an increasing number of people don't take anything you say seriously.
You're not sorry. BS and lies.
You show a pattern of using anything you can get your hands on to win an argument
Isn't that how arguments are won?
, with no regard at all for whether or not the information is accurate
You obviously have far more time than I do to verify facts. Which is why you picked solely to refute one source, and not more than one.
, or whether it even has anything to do with the particular point you're debating.
Radiant heat and radiant visible light are both electromagnetic. They are both said to be light. One is merely invisible to human eyes(guess which one).
You make it sound good because you're a very good writer, and a smart guy,
Thanks!
but the more closely people look at what you're saying, the more they notice all the bullshit that's mixed in with the good information.
Er.... Fuck! I already said thanks.
And they get tired of having to trying to figure out which parts are the good information, and which parts are the bullshit, so they stop paying any attention to you at all.
I encourage everyone to come to their own conclusions.
I was honestly at the point where I assumed a very limited few people didn't even read them(as I point out in my replies). I never claimed the examples are perfect. Or that they should be taken as gospel.
It's just
one example! Just like people claiming aluminum foil which is 92-99% pure aluminum is less than 50% reflective and yet magically causes hot spots.
Those vastly out number my
one boner, so to speak. But yet I dismiss them all. And I think any person who can read, and understand basic(fundamental) physical laws can come to that same conclusion. These aluminum haters are telling a completely contradictory tale. Fuck them haters(lol). I don't hate on Mylar. I don't hate on Foylon. I just spread information, so people can come up with their own
facts/conclusions from proper knowledge on the subject, mixed with experimentation. To prove it to themselves!
You're not trying to help people, you're just trying to get as many people as possible to pat you on the head and tell you how smart you are.
Don't be ridiculous. Speak for yourself, you'll be exponentially more accurate.
I'm sorry to get so personal
BS and lies.
, but the fact is the bullshit you're tossing out is doing more harm than good,
I'm sure you can prove that fact, instead of just claim it as fact. No? Mhmmm. Thought so.
and if you're going to keep doing that then people need to call you on it. After this one, I'll never take anything you say seriously again.
Good for you. As far as I'm concerned your science education is over.
Next!
Thats mylar that is used not tin foil. tin foil conducts heat better than mylar. try this your self cut a pice of foil and a pice of mylar leave them hang in the room then touch them both what feels colder? they are both the same what you feel is the aliminimum foil conducting the heat from your skin making it feel colder when infact its not its the same temprature! ok try this if roll the foil up and stick it down your back and then do the same with the mylar then you will clearly see aliminimum foil is not the same as mylar.
No one is talking about tin foil here.
Mylar has a microscopic layer of aluminum of it. It's subject to flaking off, wrinkles/crinkles, poor durability, and the thinner the coating the worse it reflects.
The surface of the foil being hot is not significant as it has an extremely low emissivity. It's probably doing more good than harm, as it's pulling and storing heat inside itself instead of the air.
Like I said, you can make a solar oven with either reflective Mylar or conventional aluminum foil. The major difference is durability. Mylar smokes, and is a fire hazard, while aluminum foils aren't as much so.
Just make sure to get a thick coating of aluminum!
