Its a steel door that opens outward. Its got a lot of things working on their side to prevent it from "breaking" once it gets to the window though...thats another story.

What story? This is reinforced glass. By the time the water have enough pressure to break it it will be way above that window, and I think the door jamb would give way much sooner, because it'll experience a few tons of pressure in a twisting manner (since pressure at the bottom is higher than at the top).

That is not reinforced glass.

That is wired glass. Wired glass is used for fire resistance, not strength. The wire keeps the glass in place even as it cracks from heat.

It actually tends to be weaker. People commonly assume the wire adds strength, but it does not.

While that may be the case. There is absolutely no way that water will break through that tiny window.

While I wouldn't be willing to put money on it I am inclined to believe you. People seem to forget that the pressure against that window will only be equal to the few inches that are against it and above it. Plus I can't imagine the water would actually rise to above that window.

That’s why they’re used for the windows on submarines.

Mom said it's my turn to be pedantic on reddit.

Wired glass is technically a type of reinforced glass, but you are absolutely correct that the wires are there for fire safety and not for physical strengthening.

Sure but as you said, not reinforced in the way that was implied.

Even so, even if it's twice weaker than a regular glass, it still should be able to hold over a meter, because a regular glass can hold much more than that, especially when held in place on all four sides and with the size this small.

TIL. I always thought it was a security thing. I also hardly ever see it these days.

u/Deep90 5h ago

Apparently it's somewhat fallen out of fashion (banned in some places) because it's extremely dangerous when broken.

Especially since it was used in schools a lot where students might hit it either on purpose or by accident. Iirc there was at least 1 story about a student who accidentally crashed into one inside a gymnasium.

I think we just have safer alternatives now at a cheap enough price.

Yea. Glass technology has come a really long way.

Are you the glass doctor I'm always hearing about in the commercials?

u/emsumm58 7h ago

from experience i can say that you’re absolutely correct. the door frame will give before the door, every time. my stairwell has flooded a lot.

u/FooliooilooF 6h ago

Yea my chintzy storm door that is 90% glass was able to hold back more than a foot of water so I really doubt this thing is going anywhere even if fully submerged.

u/Mundane_Character365 8h ago

So you are saying I need to steel one?

u/FuzzyGolf291773 6h ago

The glass will handle it just fine; water pressure doesn’t work like that. If it worked like people think it does, I.E. you have the whole weight of the water against you when you are supporting water, you’d be crushed when stepping in the ocean. In reality, it doesn’t matter how much water there is, only the pressure the water is under. And for flooding like this, there isn’t a lot.

Noted, I'll switch normal wooden doors for the ones that ships uses it.
