isis: We've just put down some glued on flooring from Carpet Court in our new home. Main reason was that it didn't have that hollow sound when walking over like you do with floating floors.
The glued on sounded a lot more solid. We went with an edge pattern around the house and looks quite cool!
We've got Torlys floating floor with their upgrade sound absorbing underlay on a concrete rib-raft floor, and we have absolutely no hollow sound. It actually feels a bit too solid for me, expected some warmer acoustics (I'm a part time sound engineer). The #1 reason for a floating floor is so that you can easily replace a board when it is damaged, and Torlys (and a couple others) you can pull the floor apart in the middle of the floor instead of lifting everything from one side.
I might do the edging later, it does look cool. Our builders just put in normal stuff and then Torlys undercut it to slide the boards in.
