Hello everyone,
According to our development plan, windows with sound insulation class 4 need to be installed on one side of the house, while the other windows have no soundproofing requirements.
By now, all the windows have been installed (we are building with a general contractor), but to us, all the windows look exactly the same. Even the ones that are supposed to have sound insulation class 4 don’t appear any different, thicker, or more solid than the others.
So here is the question: Is it possible for a layperson to identify this from the outside? Or what distinguishes these windows?
Of course, we paid a significant premium for class 4, but at the moment we are worried they might just be the standard windows. The general contractor, of course, says they are class 4.

You can’t see it directly because the windows just have a different construction. The total thickness is the same, only the individual panes are of different thickness. Also, there is usually an invisible film and possibly a different filling.
There are 2 ways to find out anyway:
1. By law, the window or the glass must have information about its construction. Check and compare sound insulation glass with non-sound insulation glass.
2. Tap the window with your finger. A soundproof window sounds much more muffled, while a standard window sounds more “tinny.”
Personally, I would recommend installing soundproof windows with class 4 rating in any house, no matter the location. It offers great comfort for a low cost.

2. Tap your finger on the windows. A soundproof window sounds much more muffled than a regular window, which tends to have a more “tinny” sound.Great, thanks a lot for the brilliant tip! Indeed, the soundproof windows have a very muffled sound, almost like tapping on a solid wall. In contrast, the standard windows sound quite thin and tinny. A huge difference, considering they look almost identical.
Thanks @Bookstar
