ClarkDietrich Sound Clip® (CDSC)
Quote requiredIdeal for use in multi-family dwelling, hotels, theaters and hospitals
The ClarkDietrich Sound Clip® (CDSC) is used in conjunction with 18mil (25ga) 7/8" deep drywall furring channel. It is used to fasten gypsum wallboard in various wall and floor to ceiling applications, while simultaneously providing acoustical separation. This significantly reduces the amount of airborne sound filtering from room to room. The ClarkDietrich Sound Clip increases the STC ratings in most assemblies while reducing sound transfer.
