Dedshete - US equivalent?

[clydethecat]

What's the closest US equivalent to the "Dedshete" bitumenous dampers that they damp thin-wall speaker panels with in the UK?

Would roofing felt be anywhere in the neighborhood?

Roofing felt is similar, but you get some inconsistency with it. Look up mass loaded vinyl. Aurelex sells it. Quite a bit more expensive!

This is not the same material.

I think it is worth considering the use of vinyl composition tile as a damping material. It is mineral loaded (sound familiar?). Commercial grades are ~50% thicker, heavier than residential grade.

I use it because I'm a tight wad, and it performs as well. ;)

...vinyl composition tile...

You mean flooring?

Yep!

And it occurs to me that there is probably some roll yinyl flooring out there that would very nearly duplicate "Dedsheet"

Maybe this is the closest equivalent for a '70s BBC-style thin wall cabinet:

Another thought might be to just use the Sonic Barrier 3-layer damping material:
