Window soundproofing pics

[Gypsy62]

"Soundproofing windows" thread died.
Hopefully, here's pics of 2 sound-insulated slider/art-surface assemblies, one in up position, one down:





I attempted to post detailed pics and info at other thread, but couldnt, so I'm keeping it simple here. I'm glad to answer any questions or supply more detailed pics if requested.

Your project opens a whole new range of possibilities for window treatment AND insulation. The over window bookshelf is so easy. Great job.

The pics are showing properly. Did you do a decibel test yet?
I'm curious to see how much it helped.
