My. Guess is that the laminate is doing most of the sound reduction or it is do to the smaller air space, just guessing.
The OTIS rating is slightly better though.
Dissimilar glass, does it matter which number comes first?

Todd is right on. The Laminate glass gives us the best sound protection. The next step is the spacer being used in the IGU. Sometimes the spacer has to be downsized in order to meet the windows glass pocket. If the maximum IGU is one inch they can’t exceed that width. So the thicker your glass choices has to be corrected with a spacer to get there.
