Basically a 4mm thick layer of window tint that holds the tempered glass shards in one big sheet. Not much of a deterrent in my opinion. The guy who smashes your window will just kick in the big sheet of glass and still steal your stuff.

Seems like a gimmick. I`m pretty sure just plain ol tint does that to a certain extent anyway. In either case the thief is inside your car in under a minute.

3M should just say it is an added benefit, but I doubt anyone is stupid enough to buy tint film just to slow down a thief for a few seconds (maybe).

4mm? Really? That is 5/32 inches and would interfere with rolling down the side windows, while being superfluous on the windshield.

Edit: I just looked at the article, and the film is 4mils thick, not 4mm. That is comparable to other window films.

Some companies that outfit Security Vehicles have used stuff like that for years, and it works well within reasonable limits; whole different ballgame compared to regular tint films, not even close.

IF the 3M stuff is relatively marring-resistant, good in the optical sense, and as tough as the older stuff, then it might be a nice improvement over what was previously available. I seriously considered such stuff at one time, but the older versions had too many downsides (unless you replace it regularly and that`d be awfully pricey).

I never thought of it as much of a *theft* deterrent, but rather a way of slowing down the ingress of somebody with, uhm...other crimes in mind, and a better means of avoiding a faceful of glass during such incidents. And maybe it`ll buy somebody those critical two seconds that can make all the difference. Good on 3M for this one.

Looks like they`re trying to expand, they already sell these for Home security but a lot thicker and effective (based on side by side video comparisons) . I would like to have the Home ones for my windows and sliding doors, looks like it gives the thief a good workout before being able to access your Home and if you have an alarm it may cause them to give up and flee.

Whoops.. sorry about that. Quite a difference between 4 mils and 4mm. Wasn`t thinking when I typed that. Got the 4 part right at least:)

I don`t think it would be very effective for that purpose either, at least not in the typical retrofit application. The glass/security film combination would need to be held very firmly in the frame in order for it to prevent ingress, otherwise the burglar would just push the shattered glass/security film combination out of the frame.

Same thing with the household glass, if it buys a couple of extra seconds (literally just two) that can make all the difference. If you`re gone and they get in, OK...they can steal stuff. If they`re up to something worse, something that involves your being there, then anything that tilts the odds is a good idea.

I mean...the ability to smash glass isn`t really necessary to gain illicit access since most anybody`d just use a glass cutter instead, which I`d certainly expect to cut right through the film too (and if it doesn`t then that`d still be easy to do with something else once the glass has been compromised).

Though for a *business* I can sure see it, oughta defeat the casual smash-and-grab quite effectively. A lot of those really *are* casual, over-and-done in a moment or they give up.

E5 Glass > 3M "security" film

One of the best OE mods I did to my ride.

So all manufacturers are required to label which glass they use, tempered, regular etc. I don`t know all the codes but I do know for Volvo it`s E5 which is their code for laminated glass. Laminated glass is actually 2 sheets with a film in between, it`s insanely strong but more importantly, it KILLS noise (Esp wind noise). Also great if you find yourself driving through an angry mob!

Same windows I have in my R, this is just a wagon.

Also note, I`ve switched out all my glass including mirrors for euro spec. It`s a million times better! European spec mirrors require a wide angle veiwing on the edges. Also installed a Convex rear view mirror as well. All together it makes driving 1000x better.

How do European first responders deal with that glass? I guess it takes a tungsten spike or something similar to break it.
