The RSIC-SI-X Low Profile is designed for use with any wood framed and steel framed ceiling system where vibration and noise control is needed. The RSIC-SI-X isolation spring ceiling system assembly decouples and isolates the gypsum board or plywood from the structure with a low profile spring increasing the acoustical performance of the system. With an Acoustical design load range from 7 lbs to 25 lbs per isolator, the RSIC-SI-X resilient sound isolation clip can support up to two layers of 5/8″ gypsum board. The spacing at 16″ x 48″ oc is the same for 1 or 2 layers of gypsum board.
