floating floor on existing floor - ??

Guys,

What's the best way to attach a new floating foor of 2x4 on it's side on rubber feet to the original timber particle board floor? I,m thinking:

(a)bolts
(b)large nails
(c)don't attach at all, let it "float"

if the answer is (c) how do I attach the new "inside room" to the existing "outside" room for stability. Where the best place?

Thanks

JohnG

If you're floating a floor, but want to attach it to the existing structure, it won't be floating anymore. The structural connection will defeat the purpose.

Are you worried about your floor marching around on you? You'd have to vibrate the floor hard enough to make it actually bounce up and down off the sub-floor, and anything that can generate that much LF vibration is going to be heavy enough to weight your room down.

Let it float.

Kase is right, the answer is "C" -

Depending on your DIY abilities, you can either build your own "sway" brackets for the tops of walls, similar to my illustration here -

Or, if you have no way to build your own brackets it gets more costly -

If you do a thorough search of kinetics' site they have install manuals in pdf, etc, that are fairly educational. Buying their products requires getting the contact info of their local rep, they don't sell direct as I recall... Steve
