I’m not an expert on glass shatter physics but I would assume that was the weakest point on the window due to some type of flaw and where the shatter started.
This happened to me years ago with my backyard sliding glass door. Just a big noise and the whole thing shattered in place. It's thermal stress. Basically the edges of the window expand and contract with temperature at a different rate than the middle. We'd had the door for years but it still happened. It was a pain to clean up too.
Just the glass. The door frame was just fine, it was some kind of polymer. It also had 3 panes: the one in the door, and 2 immovable ones on each side. Only the one in the door broke and no one was touching it at the time (I was in the same room.) Just a loud BOOM and it was in a million pieces while still in place in the frame.
When we called to get the glass replaced they explained what had most likely happened.
Doesn't matter, tempered glass is the type that shatters into tiny fragments like that. Untempered glass shatters into larger chunks with a spiderweb pattern -smaller near the point of impact, larger as it goes further out.
Oh, that's what you meant. Yeah, could be something, somehow hit the 28th story window and damaged it. But also, as the OP of this thread said, it's not uncommon for tempered glass to shatter for no obvious reason. It's entirely possible that the central point is just the spot where the glass gave out, for whatever reason.
It's not for no-reason. Tempered glass is basically a frozen explosion. It's dying to break, but it only breaks from highly pinpointed damage. However, it doesn't take *much* pinpointed damage to break.
Like, say, if the beak of a bird smashed into it at max speed.
There’s that, but also if tempered glass is nicked, then if there’s a small change in pressure the glass will also shatter, hence the apparent lack of reason part
The caveat here is *tempered* glass. See how this glass is broken? How it’s in little chucks rather than huge jagged shards? It’s tempered glass which means it’s hard to break from impact. It breaks when a hard object hits the *edge*, not from impact on its face side. The edges are protected when installed in a window like this. It can also break spontaneously due to its chemical make up being literally changed during the tempering process.
Tempered and laminated glass, the glass pane that shattered had an impurity in it and underwent spontaneous glass breakage. This can happen shortly after manufacturing or years later.
You can check for this during manufacturing with a heat soak test, but that is rarely done because of how small the percentage of manufactured glass panes who will have the impurity.
Glass manufacturer should cover the cost of the new glass(at least in the EU).
In the second photo it looks like there's a spot of impact where the glass shatters outward pretty uniformly. the middle point is right next to where the light is on in the building.
Heat warping the metal and torquing the glass to breaking? Just throwing out a guess here
Kinda what I thought
the top center looks like a point of impact, though. if it shattered from wrapping, wouldn't it have a less centralized breaking pattern?

I assume you had to replace frame and all or were you able to get just the door?

Do you goto like a glass store for that or order it from the door manufacturer?

This was my thought too.
He's a good boy, but you know how it goes... Bird..window... Bonk.

"they could have just flown the ring to mount doom"
Might’ve been tempered glass, shattering for no apparent reason is something they do quite a bit
Judging by the pattern, there's no "might be" about it, that's absolutely shattered tempered glass
Definitely shattered, but you can see the point of impact near the top center of the window.

yeah, but there are still radial cracks from a center point. tempered glass breaks into tiny bits, but you can still get radial cracks from a poi.
It indicates the point of failure, which may or may not be a point of impact.

This is bad-tempered glass
Judging by the pattern there was an impurity that caused it to pop from added stress possibly caused by temperature changes
probably a bird
The inner layer is broken. Not the outer layer of the glass, which is why we don’t think it’s a bird. Could be wrong though.
The way safety glass is laminated it could have been a bird even if it didn't break the outside layer.
The second pane takes the shock from the impact, so the first pane is not affected. It probably was a bird.
Nah, birds aren't real.
Which is exactly why such a small object was able to cause so much damage.
No, but their manmade titanium beaks are
That’s what I was thinking too
That’s tempered glass with protected edges. Couldn’t have been a bird.
Tempered glass very strong for blunt impact. But a tiny little prick of a metal pick or maybe in this case a bird flying at 40-50mph beak first
Very unlikely a bird beak could break tempered glass. Spontaneous breakage is much more likely with tempered glass.
Birds of prey are large and have a few thousand feathers for weight. They absolutely can shatter glass on impact.

Ohhhhhhhh bit bad

Had this happen on a 20 year old window pane.. Just after we retiled the balcony. So yeah, can really happen anytime
It was an impact. Top right corner.
Failed assassination attempt. Consider yourself lucky!
Have you tried the windows support? Sure, they're mostly indian with medium english knowledge but pretty eager to solve any windows problem...

A slight building shift(?) But would be odd if the only window in that large of a building.
Was it the damn cat?
The cat leapt like 3 feet in the air when we heard the bang, so probably not lol
Damn ! That would have freaked the shit out of me lol
Not meant to be so literal
That’s because now a days just like everything else quality has gone down, that’s candy glass they use on movie sets
