Metal Studs in Floating Basement Wall

I have read on this post that you can frame a floating wall with metal studs, but I am not quite clear. Here's my question,
1. You start with a 2x4 attached to the concrete floor.
2. This is where I am confused. Do you use a metal stud for the botom plate? Not clear on how it would float with a large nail going through a metal bottom plate, seem like a sqeeky situation here? Can someone clarify? Yes, I do live in Colorado.
Thanks,

You use track for the botom and the top of your wall. Your metal stud fits inside of the track. Screw the track to your 2x4 witch is attached to the floor,and use track at the top of your wall which you will screw to the bottom of yor floor joists. I use 1-1/4 inch drywall screws to attach to the wood members. You can use mini screws to screw the studs to the track. If the wall needs to be free floating, cut your studs 5/8 inch shorter than your actual wall height and don't screw the stud to the track at the top. The track has 1 1\4 inch leg so your studs will still be in the track but won't fall out. This still leaves plenty of room for diflection in the floor.Go too yor local supply house and you should find all these materials there.

 

so, on the floor there will be no floatingoccuring, that will happen at the top? On a traditional wood floating wall you use a 40 p nail to hold the bottom plate above the 2x4 on the floor. You are saying attach the metal track directly to the 2x4 and the stud at the bottom, but not at the top? Why have the wood there at all? Why not attach directly to the concrete on the floor?

 

You can attach directly to the floor, but some people like to put pressure treated lumber down first so your bottom track won't rot if you get water in your basement.

 

Ok, clear on the options for the bottom. Thanks. Now for the Top.

You state not to attach the metal studs at eh top for a free floating wall? Then where do you attach your drywall? It seems that you have to attach it at the top track and at the bottom. That's the way you do it with wood studs, but where is the float with the drywall attached in this manner?

The track is connected to the framing above. The track supports the top of the floating wall within, allowing it to move vertically.
