Auralex’s RC-8™ Resilient Channel is a specifically designed durable, yet flexible 25 gauge steel channel used to attach drywall indirectly to the supporting wall structure. This mechanical decoupling increases the sound transmission class of the wall or ceiling system. The performance of RC-8™ can be enhanced using dual layers of differing thicknesses of drywall with a layer of Auralex® SheetBlok™ in between.

RC-8 has higher density (harder) and it makes to drive the screw through very hard, even if I used short screws for metal as recommended.
It also makes it harder to cut. If you are a big husky men, it is probably not a big deal. But I am a woman and it took a lot of sweat for me.
I am not sure why they claim that stronger metal makes a better noise insulation because the purpose of the channel is to decouple a sheetrock from the studs. It seems like any RC channel shall do the job. Ironically, after I finished my project, I found resilient channels at Lowes in sheetrock isle $4 each.
First, FoamTek will allow you to remove the acoustic foam from your walls, leaving little residual adhesive — adhesive residue that is easily removed from most surfaces.
Second, one can of adhesive, judiciously applied, can be used to mount 50 sq. ft. of acoustic foam.
FoamTek costs more than other adhesives, but it's well worth the extra expense.
Be sure to go to the Auralex Website to view informative videos on how to properly cut acoustic foam — use an electric carving knife — and how to properly apply the foam to wall surfaces using FoamTe adhesive.
(I did not use Auralex brand foam, but instead ordered all my foam direct from a manufacturer in Michigan for a fraction of the cost.)
Not entirely sure if it's the walls like i first said or something else, but that's my only theory.
However there is a "calking" type form of this product which I HIGHLY recommend. holds MUCH better than this stuff. Try search TubeTak to find it.

Learn from my mistakes and don't waste your money on cheaper products hoping they will work. Tried £4 and £7 spray glue for acoustic tiles before this one.
