This system is supposed to offer better sound control than masonry . . . . -------------------------------------------------------------------------------- Interesting since this is contrary to my experience living with both kinds. While I have been unable to find any published numbers to support (or deny) my experience but there is some data at http://www.practical-home-theater-guide.com/support-files/making-walls-quiet.pdf In the table from the link - (which lost its formatting in the copy and paste) - the number before the word "Note" is the STC- Sound Transmission Coefficient . The higher the STC rating, the greater the sound attenuation of the acoustical barrier: that is, a higher number is better. The link notes that the numbers don't add if you add attenuating elements together, i.e. two walls 5/8" Drywall both sides (at STC = 34) don't make an STC of 68. I have no connections with any of the products being discussed.
