The DensGlass detail is a gypsum area separation wall and more appropriate for townhouse separations. A two family could be separated by something less than that.
celticfunding should look into a simple UL Listed rated assembly or perhaps one from the Gypsum Association book. As I suggested on his other post, I think his concern is the continuity at the floor ceiling assembly for side-by-side units.

A one hour separation is as easy as a 2x4 wall with 5/8 on both sides or maybe less in some cases, watch for supporting construction rating if needed as well... I have more issues with people not getting penetration details correct in the field....
