Brake in the handle
How many times have you had a draught slamming a window or a door? That's the solution for this kind of situation; the hinge arm, I block the maximum window opening.
When opening a window or terrace door, turn the handle to the position, close the window, then the position of the sash is blocked, so that the window sash cannot be moved in any direction. A very useful function, during drafts, will protect your windows against accidental damage, and certainly against slamming.
