The main purpose in my opinion is that when the window is tilted open, it's still almost as safe as when it's closed, while still giving you a breeze inside the house. Keep in mind that this windows are sturdy and quite heavy with often triple glass so is not something you easily brake or force.

Newer model have crazy good insulation.

    It still seems incredibly over engineered. Every window I've used in the US has a latch you flip out that prevents the window from opening more than a couple inches so that it's still effectively locked. Newer windows here are also all double or triple panes with inert glass in between the panels for insulation.
