Is anyone here familiar with a company called Quiet Solution, making
some sort of polymerized drywall panels? A friend is unwilling to do
the usual dual stud or staggered stud remodelling to soundproof his
house, and intends to use these things. Seems like it could be snake
oil to me, and they are NOT cheap ($120/4x8).

Appreciate any feedback, thanks.
