What about this Semi-Floating-Sub-Floor system?

Below is a link for a sub floor system I ran across in another post (not sure which post!). I was wondering how well this would work to assist in stopping floor flanking noises. (Check out the installation video) http://www.subflor.com/ADVANCE/home.asp Also, I wondered how well this would stack up compared to the suggestion (butyl sheeting) Knightfly gave me for having a "semi-floated floor" in this post: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=4845 Another question is because I'll be placing my framing on top of this, (which will include the weight of the drywall etc etc) I'm wondering if this system could handle that much weight and also, how far back from the very edge of the last flooring "sheets" would I have to go to put my frame up? (For the flooring sheets to securely hold all the weight mentioned above) I plan to check with the manufacturer today and post they're comments here.

It might help a bit with footfall, but I doubt it would do much for airborne sound... Not enough mass. --Keith :mrgreen:

Cami, it won't even help with impact noise (foot fall) - in fact - it will probably make it even worse. Because of the fact that this is a high impact hard plastic base - all of the energy will now be transmitted through the plastic "spikes" that connect with your floor........... bad idea - I would suppose it works well (however) for it's intended purpose - which is comfort - not isolation.

Thanks Keith and Rod... :) Just so you know I did get a call back from a rep at the company. He said each panel is designed to take up to 9000 lbs (He stated that a car could be placed on a finshed constructed floor). He also said it's mainly made for basements and will raise the floor temp 5-7 degrees. He's sending me a bunch of other stuff in the postal mail but I guess I'll mainly be looking towards possibly using this product in a basement office (If/when I have to take up my laminated floor in that room). Thanks again for the input! :)
