you mean laminated glass ?

No they mean double glazed. Two layers of glass with a thin layer of air sandwiched between them. Windows are built like this in countries where the outside air temperature is far different than you'd want, as otherwise you spend a lot of money heating or cooling your windows, because glass is a poor insulator. But _air_ is a relatively good insulator considering it's transparent, the two sheets of glass stop the air…

cool, I didn't know that about double glazing being strong.

Here in Sweden most house have triple glazed windows

Isn't the point of a lock just to keep honest people honest? I mean you can buy the world's sturdiest, more secure lock and attach it to the world's strongest door, someone with a hammer can easily break a window. If someone is determined and willing, there really is nothing you can do to stop them from breaking into your house.

No, because then we would all be using wafer locks on our front doors. There’s a balance between strength and price here.

When someone is trying to break into a house, they might have to do it fast, so that they don't get noticed. If they need to pick two locks instead of one, it's costing them twice the time, so by locking the handle in addition to the deadbolt, you're increasing your security by making your door a bit more of a pain for someone to break into.

Who picks a lock to break in? Common thieves have no need to pick locks.. totally dumb for a couple reasons. Contrary to popular nerd belief... door locks in the US are not that easy to pick. Many have anti pick features like reverse sidebars that while not impenetrable increase time or skill required. While the lockpickinglawyer has videos, note that he is extremely skilled with tons of practice, it still can take m…

I don't know about these videos but when I called my neighborhood locksmith to deal with a lock I'd misplaced the key to, it took about 20s to pick... It would seem to make sense to me if you were trying not to call attention

Precisely. You can't break a double glazed window by throwing a rock at it.

It’s still a trivial entrance point compared to a door.

"How do you know where to drill it? The lock has the manufacturers logo on the front face – drill the side of the lock in line with the top of the logo. How helpful!" In that case easy, move the logo elsewhere.

If you look at the internals of the lock then the tolerance where to drill, and still be able to leverage it open, seems to be pretty big. As such, they could remove the whole logo and it would still rather easy to approximate where to drill, it's not like measuring dimensions is impossible without a manufacturer logo.

As pointed above, it was a joke about security through obscurity and a worried thought that some manager might actually think of that as a solution. I was hoping that was obvious enough to not require a "/s" at the end.
