The RSIC-V® The RSIC-V is designed for use with any wood, steel or concrete application where noise control is required. The RSIC-V works best on wall systems. The RSIC-V assembly decouples the gypsum board from the structure, giving the assembly enhanced acoustical performance. With an Acoustical design load rating of 36 lbs per isolator, the RSIC-V clip can support up to two layers of 5/8″ gypsum board when spaced no more that 24″ x 48″ oc. For heavy loads, the RSIC-V backer can be added to support cabinets or other heavy items. The RSIC-V clip fastens directly to the framing or structure and can be used on light gaude, heavy gauge and wood framed systems.
