In the past, laminated glass was usually installed in the windshield, with side and rear windows being tempered only.

The difference is that tempered glass is per-stressed so that when it cracks, it shatters into many tiny and dull pieces. Laminated is the same thing, but with layers of plastic sandwiched with layers of tempered glass. Laminated glass will still shatter, but will be held together by the plastic layers.

In an emergency, small improvised, or purpose built tools meant to shatter tempered glass will be useless if the glass is laminated.

Anyone know of a reasonable tool that can get through laminated glass and be kept near the drivers seat?

[-] M0oP0o@mander.xyz 5 points 8 months ago

In the states? Gun.

Rest of the world? Crowbar?

Not a handgun if you want to be able to exit through the opening. Under water? Not sure a shotgun will even be helpful unless you fire at all corners to break it up more thoroughly.

18 pounder cannon, as the founding father's intended.

vixtorinox (swiss army) rescue tool. It's a locked knife - most probably illegal in many places.

[-] ColeSloth@discuss.tchncs.de 2 points 8 months ago

Use the same type of glass tool as before to shatter it. Then just push it out of the way. It's still the same glass. It just stays held together with the plastic.

[-] phoneymouse@lemmy.world 1 points 8 months ago

Will that work when you’re submerged underwater and the pressure of the water is pushing against the glass?

[-] ColeSloth@discuss.tchncs.de 7 points 8 months ago

Instead of pushing out, the water pressure will make it fold in on its own after you crack it.

[-] cynar@lemmy.world 6 points 8 months ago

The recommended (and slightly terrifying) advice is to let the car fill first. Basically, use the time and air to prepare yourself. When the car fills, the pressure will equalise, and you can push the windscreen out with your feet.

Unfortunately, unless you've thought it through beforehand, most people panic.

I would assume that when shattered it becomes flexible so you can move it out of the way

[-] Confound4082@lemmy.ml 2 points 8 months ago

A "Glass-Master" is what I used in the fire service. Goes a lot faster than you would think.

[-] RightHandOfIkaros@lemmy.world 1 points 8 months ago

They make safety glass shatter tools and they usually also come with seatbelt cutters attached to them as well. Looks like a really large, sharp ballpoint pen tip.

[-] NOPper@lemmy.world 15 points 8 months ago

These don't work on laminated glass.

[-] boyi@lemmy.sdf.org 0 points 8 months ago

I thought 'victorinox rescue tool' works for laminated glass. It even has glass cutter.

[-] doggle@lemmy.dbzer0.com 1 points 8 months ago

I would guess you could use a regular tool for breaking a normal window, then cut through the plastic with a sturdy knife. Not great to need two tools in an emergency though, and keeping a combat knife in your glove box might raise some eyebrows.

Unfortunately, being difficult to get through is the whole point

Small bits of ceramic, like from a broken spark plug easily shatter any tempered glass even when thrown lightly. https://www.jdpower.com/cars/shopping-guides/why-do-spark-plugs-break-windows

They asked about laminated glass not tempered glass.

[-] doggle@lemmy.dbzer0.com 2 points 8 months ago

Laminated, not just tempered. There's a strong layer of plastic inside the window. Even if you shatter the glass you still can't get out.
