The latest and most efficient rated low profile wall and ceiling designs utilize the HUSH MOUNT™ type RDIC Resilient Drywall Isolation clips. Used in conjunction with standard drywall furring channels (hat track), RDIC clips increase the air cavity between the mass of the wall/ceiling (drywall) and the non-isolated structure (framing studs or joists). Resilient decoupling of the drywall and framing results in a compact, low profile discontinuous construction which boots the Sound Transmission Class (STC) and Impact Isolation Class (IIC) ratings. Standard 7/8' or 1 1/2" hat track channels snap into the RDIC clips on 24" centers horizontally. The gypsum board/drywall attachment to the hat track can be with conventional fasteners, and practices without concern for short circuiting the system. Tested single wall 2 x 4 designs yield STC ratings of 56 to 64 well exceeding similar designs with resilient channel decoupling.
