When you need to stretch your essay so you can get to 500 words. Holy shit get to the point.
🤣🤣🤣
Fucking frfr...
😂 seriously
Lol, I was coming on here just to say that.
😅😅😅 this is great I hate all this talking
99% of drivers don't know what they are for, because only 1% of people have the patience to watch the whole thing til the end before moving on.
And then that 1% still don't know since the video gives the wrong answer.
😂😂
Imagine having an attention span longer than 5 seconds in 2024
u dont know too
I knew right away. It's also on our oven and microwave.
Its called the "frit" and it protects the urethane from UV breakdown. I've been an autoglass tech and auto glass small business owner for 27 years .
🫡
Me too but for 323 years now.... I'm about to retire in 2 years at 325 years going!! Its been fun... time to travel the world for the next 500 years or so!!
@simonbenn5340 are you mad I built a future for myself? What a odd post to bash on someone. Let me guess single mother, part time jobs your whole life ? Can't stand to see hard work and success , wants the govt to hand you a check ? Moms basement as an adult? All u need now is some trigger words to complete your snowflake journey
@simonbenn5340 are you upset I know the industry? Show us on the doll where your single mom hurt you . Don't be mad pops was upset at how you turned out .
And? Do you want a medal or something. Boring job how the hell do you do it.
Never getting those seconds of my life back.
it wasn't being used effectively anyways :)
@@pc-ft9dy lol true
Losing the same number of seconds from my lifespan in solidarity with you 💪
i mean its useless anyway so who cares
what about the second you lost to leave a comment oxygen thief?
They are called ceramic frit, it stops uv light from affecting the urethane bond between the windshield and the pinchweld.
I like how that sounds better.
Thanks a bunch!! 👍🏽 I'm educated now! 👩🏽🎓 😄😄😄 😆😆😆 "Ceramic Frit." 🤔
I've seen it on the windshields and examined it occasionally, and I never knew what it was for. 🤔🤔🤔
I've been LICENSED to drive since 1990; I began "PRACTICING" driving when I was 12 years old in 1972... supervised by my Dad, of course! 👨🏻 ❤
😬😬😬 😏😏😏
Thank you, I was JUST about to write that out... this video is complete garbage. Definitely there for the urethane.
TY
Yep, I've used it on many yacht windshields.
100% of drivers don't give a fuck
Exactly 😂. Actually he didn't say most of the back edge is for primer glue. Black paint Stick to the glue/primer and the to the car frame 🤦
...and the other 10%...(oh, wait)
Facts! 😂😅
Not that you would give a fuck, but that's 100% wrong.
I drive and I do give a fuck, so it's certainly not 100% not giving a fuck. Man that's alot of fuck btw.
I have always wondered it so you're wrong
Those dots are called a “dot matrix” it is a part of the “frit band” that runs the outside of the glass. In most cases it helps primer less urethane adhere to the glass and body while simultaneously keeping UV rays off of the dried urethane to help preventing dry rotting and the urethane cracking.
You must be a window tint installer. That’s for info
@@DavidSanchez-wm8wd close. Automotive glazier.
I've never heard of a windshield spontaneously shattering prior to the invention of these dots.
They use the black enamel outside the windshield to block the sun's ultraviolet rays from melting the adhesive underneath the band. This keeps the windows firmly glued in their place. The black dots, or “dot matrix” actually help distribute temperature evenly to lessen optical distortion or “lensing”.
Mr Google
Spot on. The sun will deterioate the urethane.
Thank you
it's a "frit" I was amazed that this robot spouted this bullshit
Thanks. You should've narrated this short.
The special glue used to fix the glass is sensitive to sunlight, long exposure makes it brittle, so the dots help with keeping some of the sun away while blocking less of the view than a solid black stripe. You learn this detail while getting certified by SIKA, one of the makers of this kind of glue.
Thank you
This is the reason. The guy who made a whole video about it, didn't even manage To give a reason on why those dots are even there.
I came here to say the same thing, lol
Thanks for the info. I thought they were an antenna. ❤
thank you for explaining why because this video absolutely did not!
none of the cars in the 1960's or 70's had these and I don't remember any cracking glass due to heat.
I think because back in those days there was no rapid environmental destruction which could lead to high temperatures but these days environmental destruction is excess
@@sgwlw7777yeah those days in summer time also my mom told me they use to wear sweater cause it cold.
@@sgwlw7777 are you serious lol
@@kevingilmore9366 yes
Well, that's 20 seconds I'll never get back
If you eat healthy food and do exercise everyday those seconds won't matter....😅😅😅😅😅
As a kid in the 80's I was sat in the back seat of my parents' Ford Taunus on a quiet and nice sunny day while we were taking a drive. Suddenly the rear window exploded all on it's own, glass all over the back seat, so I for one certainly appreciate and understand the reason for this improvement.
I don't think I've heard of a Taunus, what's under the hood?
A engine
@@GODh8sfag5 It was a 1.6L four cylinder engine. Pretty normal engine for a car in Europe in the 80's.
The spontaneous breakage like you saw is usually due to a defect or inclusion of a small particle called nickel sulfide that expands over time and can break tempered glass.
B.S.
For one the windshield is laminated and not tempered. That black band around the windshield is called a "FRIT BAND" It hides the glue used to install the glass. Laminated glass does not explode it just cracks. You would have to really smash up laminated glass before it is a danger.
This video is total BS.
Every winter for nearly 25 years, my dad would go out every morning there was ice or snow on his windshield with a pot of boiling water and pour it to defrost his wind shield with no problems whatsoever. On two sperate occasions I've poured a cup of hot water on two different windshields to help me break up the ice so I could use a scrapper to get the rest off, ending with both of them cracking. This only tells me the manufactures are making the windshields weaker and weaker over time.
Turned him saying "Black dots" into a drinking game and now I'm dead.
The black stripes and spots are called the frit. During installation, the frit is a bonding point between the glass itself and the frame of a car. The frit is baked into the edges of the windshield glass so the glass bonds to the frame. The windshield component also hides the adhesive to provide a polished appearance.
While the side of the frit that is facing inwards bonds the glass and the frame, the side that is facing outwards has a different purpose. The side that is facing outwards keeps the UV radiation from damaging the adhesive. Long-term exposure to direct sunlight that is damaging to the adhesion in the glass. UV radiation can damage or weaken the adhesion over time.
I believe the dot(singular) is called a "frit". The plural version is, "frits".
@@budlanctot3060 yes - getting more detailed/specific... the dots are the frits and the black band is the frit. But both together, is more generally known as just the frit.
Glass is glued in with urethane and is sensitive to ultra violet light and becomes rigid and then thermal expansion is an issue.
U can apply the technology to the actual frame of the car as well as the frame of electronics to prevent overheating even the separate parts of the car to prevent overheating in the engine
A dealership will tell you its a antenna 😂
That’s exactly what I thought it was. 😂
They would be wrong.
Now you are almost correct usually the antenna is part of the rear glass. I have seen one windshield that had one once. I forget what vehicle it was. Many rear glass antennas look like they are part of the defroster and are usually right above the defroster. If the vehicle had that setup.
@@spagsketti I just said it's what a dealership will tell you bud
I always thought it was part of the windshield heater element
What is the deal with this voice on every freakin video?
Artificial intelligence voice
@steelisthemeal thank you captain obvious. Why does it need to be on every freakin video? There are thousands of AI voices that can be created. This one is so annoying and on everything.
@@jeffs6090 I'm with you on that. It must be the first choice on the voices list or something and they pronounce all kinds of sh.t wrong too.
@@stevie.dx1710 It sounds like AI Ice T
still better than TikTok voice
Good job you make a minute feel like an hour with your overly complicated explanation of something so simple 👍
Its called a dot matrix and it has about a dozen uses. The only one we get is it reduces sunlight on the edges of the window. Some windows have a 4 inch strip of them across the top.
BULLSHIT. I HAVE HAD 3 TRUCKS WITH THESE DAMN DOTS. ALL 3 HAVE CRACKED DURING THE SUMMER.
It'd be way worse if they weren't there. I remember back in the day when they hadn't figured that out yet and no cars had them. Nearly every car on the road that wasn't kept in the garage had stress cracks in the back glass or windshield within a year or two from new. Best way to stop it is to keep it out of full sun in the sunmer.
I would bet there was a rock chip in the glass that caused it to crack. A rock chip on the edge or close too it will crack faster than one in center of the windshield. There is a lot of pressure on the edge when the glue cures out.
What about the side windows?😅
They're not slanted like the front and most back windows which are more directly hit by the sun for longer periods of the day. Think a little. It's easy.
60 yrs of owning a car, I've never had this issue and never heard anyone else have it either.
Windshields are "glued" on to the car body. This fretting protects the "glue" from the suns heat while avoiding an abrupt temperature difference on the glass...
absolute Bollox So why does the door window not shatter
It is tempered and windshields are laminated.
Well I am an auto Glass technician
Well how about the clear glass who doesn’t have a black shade around the windshield?
I think it’s just cosmetic instead of looking at the urethane ( you guys call it clue ) they put it out there to hide it
Well I could be wrong
I have a question for you, on my toyota windshield there are some small sort of code printed randomly on the glass, any idea the purpose?
@@sanookaus1334 it’s a print of the manufacture who made the glass if it’s never been replaced you will see the same print on each door window
@@samirhadjou8163 One more Question if you don’t mind, why are the side mirrors reflection not true to size, as everything looks far away. Cheers.
I am surprised U don't know it's for the HVAC System
@@StationRussification how about the clear glass
THANK YOU WHOEVER FIGURED THIS OUT
That black ring also hides all those dead bugs and spilled candies and drinks that can't be cleaned out because the glass is very close to the dash.
Another indian bot channel 😂
I always thought it was for safety so the glass wouldn’t shatter never thought about thermal heat. That’s awesome
Wow! I always thought it was an embedded AM/FM antenna.
Explanation: The Black dots relieve the glass from heat through dissipation.
Thank you
Nice design, excellent thought 😮
Thanks for the info 👍🏽👍🏽
The front is not for heat. it’s to fill gap between visors sometimes, but always to not show the blackout as a smooth line on a curved surface (black out is to cover adhesive)
I got those black dots and a crack going from one side of my windshield to the next.
Back to the drawing board for him.
I used to work for a glass manufacturer. It's actually painted on the inside of your window. Then taken to a furnace that bakes it to the window and bends it to the curve it needs to fit in the car.
While that may be partially true. It’s called a frit band and it protects the adhesive from the UV rays of the sun.
It's called a dot matrix used for the robots to line the 2 sheets of glass together, and to keep uv light form destroying the glue.
Michael 😮
It's crazy bc I was just thinking about that a couple of days ago. I thought it was like built-in sunglasses. I know the visor is there but I thought that was like the first defense.
Any Inventor is a genius
Also if u look on your windshield there is an As1 mark on both sides about 6 inchs down fro. The top ..if you put visor tint below that mark , its illegal. Above that mark , you can make the tint as dark as you want .
Thank you!!! I have learned something new today. 🙏
You still haven't. This video is wrong.
I never knew that when I had to replace my hummer windshield the new one that was installed. Had this on it and I always wondered why was that on there now I know. It’s funny that the factory windshield didn’t have it. And I live in Las Vegas, where it gets really hot so It’s nice that the new windchill has this
If there was a world record for the most words in a CZcams short… this channel would definitely be on it. That has to be a record 😂🫡
"Hey, those little black dots on the windshield? They're for heat dispersion in the glass". 10 secs.
I always thought it was to weaken ice at the edge of the glass to make it easier to clean off
Windshield is what we call a safety glass …… it doesn’t shatter like the windows because there’s a film in it that doesn’t allow the shatter . Tempered glass will be the one u gotta worry about but it doesn’t have that either however u can tint them .
The color black and the Sun have a very special relationship. The same with a certain group of people 😊
The more common reason is the adhesive that holds your windshield down, weakens overtime in direct sunlight. It’s more aesthetically pleasing to look at the dots then just a black border around your windshield of silicon.
I literally used to design and print these on glass for military vehicles.
At some point I was just watching this short, not to find out the answer, but to see how long it would take him to get to it
I think these dots were introduced to hide distortion which typically occure next to the frame.
I remember back in 70s windshields eplode evrytime you parked in the sun.
The struggle was real!!!!
Just recently I asked my Mother, "Hey Ma, do you remember when the car's front windshield had about 4-to-5 inches of blue or green tint?"
Interesting, I was always curious about that
This is knowledge 😊
Relieving the stress of thermal expansion.
Could of said "Hey the dots on your windshield are to distribute HEAT"
BAM💥👍👊
Me sitting in my car on break gaining more knowledge! 😮
Amazing!!!!!!!😮
Master engineering!
I’ve never felt so impatient watching anything ever
Saw those dots and never wondered about them. Learned something else today.
the dots have an exclusively aesthetic purpose because they serve not to see the glue for the glass, so they represent a transition from opaque to transparent
The black lines across the rear window are insulation for defog. I recently damaged mine getting tint glue off and now when I use rear defog my radio goes static... oops
I I didn't know that, Thanks for the information.
Rear windscreen blew up on me once. Peugeot didn’t allow for expansion/contraction in the 106 model. Ice then warmth. Pop. Not cool. Massive bang. Thought someone threw a brick in the window. It was a courtesy car!
Learn something knew everyday 🔥💪🏾
There goes 30 seconds of my life I'm never gonna get back.
If this is true, why do the windows on my house not have those dots?
Moreover, why don’t they crack every summer?
So funny how right when he said the further from the edge the smaller the dots, as they show that there are tiny dots right next to the edge.
Thank you for telling us God bless ❤
It’s also designed to hold the windshield urethane on the glass
It's to ease transmission of direct light between opaque surface and transparent glass or in other words to reduce dazzling.
Very interesting, never knew that.
I love your style!
I have walked outside to my car living in south Florida during summer and found a shattered window ..the heat here is out of control ..you have to leave your windows open a lil bit
Never knew a short could be so long😢
It’s relieves the stress that heat can put onto the windshield.
My grandma loved the sun, would bake for hours, not once did her glasses shatter.
I want to how glass used to work in the 60s and 70s when they didn’t have the black dots. I don’t remember when those breaking all the time.
It prevents rubber break down on uv rays.. (seal bethween glass and car frame)
this is something i actually knew for once :)
😂 why did it take so long to say “distribute heat evenly to protect the integrity of the windshield”
Who else watching this while driving and looked over at your windshield?
David Cruz
My windshield is 24 years old. Those dots have long ago faded away.
Nice story, I'm a Auto glass installer and business owner for 40+ years the dot matrix design was created for the use of the installation product called Urethane a black adhesive rubber that cured or hardened that held the glass in place.
This product Urethane when it hardened gave a strength of 400 to 600 lbs. of strength per inch allowing car manufacturers to make a lighter car but maintain roll over strength for the roof.
Prior installation method used was called Butyl tape on a roll which came in 2 sizes 3/8 and 5/16 of an inch but only had the strength of 15 lbs. of strength per inch then a chrome molding was snapped around the edge to hide the look.
The dot matrix and black edging was in fact a the replacement the old molding style to hide the Urethane so it would not been seen and gives a crisper look.
Why not needed in earlier decades?
Spoiler alert: It helps prevent cracking from heat.
Took this guy forever to get to the explanation
When I wear polarized glasses while driving I see dots on the windshield and I always wondered what's up with that?
That is not what I was taught while training to be a glass tech, we were taught those black dots are there to keep the area cool where the adhesive is and it distributes the heat away from the area. Notice all of the black covers up every area where it attaches to the vehicle...
I always wonder what they were for oh thanks for the information I never knew😮
99% of drivers didn't watch the video long enough to hear what they are for.
Thank you for this information
Man the anticipation gave me rly bad anxiety..
It’s the defroster. It literally heats the glass up when you hit defrost
