My pleasure - it really is a beautiful build -
What you're talking about here would be similar to room treatments in your mind - you absorb the reflections and thus lower the resonance of a room..
When it comes to absorption - you would need much larger quantities than that small strip of fiberglass to create any effective absorption..... and what little sound might pass through the crack between those 2 walls (which will in some small part be absorbed by the much larger quantity of fiberglass within the wall itself) - after it passes through the fiberglass trim strip - is relatively small as well.
These systems work simply based on the decoupling effect of the walls - as well as the mass of the glazing - and in your case - a little extra beef due to the fact that you have laminated glass.
The fiberglass strip is a manner of handling the void between the a frames while maintaining a decoupled assembly- just a very clean neat & effective architectural detail......
