SOUND ISOLATION AND DAMPENING CLIP
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-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.
- Ideal for use in multi-family dwelling, hotels, theaters and hospitals
- Used in conjunction with 7/8" 25 ga Furring Channel with a total standoff from stud of 1-5/8"
- UL fire rated for most common assemblies
- Complies to UL 263 test standards. See full list of UL® design assemblies in UL R19331
- Rubber ASTM standards: D2240, D2000, D412, D395, D573, D1149, D2137
- Maximum spacing 48" o.c. (laterally) x 24"o.c. (vertically)
- Maximum acoustical design load is 36 lbs.
- SOUND TESTING FOR TYPE X & TYPE C BOARDS
