The RSIC-1 Sound Isolation Clip is the industry’s most economical and effective solution for reducing sound transmission in wood, steel, CMU, or concrete wall and ceiling assemblies. Engineered for both new construction and retrofit applications, the RSIC-1® system decouples and isolates gypsum board or plywood from the structure, dramatically increasing acoustical performance while maintaining structural integrity.

Each RSIC-1 clip supports an acoustical design load of 36 lbs and can carry up to two layers of 5/8″ gypsum board when spaced at 24″ x 48″ O.C. For heavier assemblies, additional isolators can be added to meet load requirements. The clip and 7/8″ hat channel (noted below) creates a 1-5/8″ cavity between the framing and drywall, stopping airborne noise and vibrations that would otherwise transfer through rigid connections. When used with 7/8″ 25-gauge galvanized steel hat channel, the system ensures professional-grade decoupling, significantly improving both airborne and impact sound control.

Versatile Applications :

The RSIC-1 can be installed in residential, commercial, and institutional projects where high-performance sound control is required. It is also approved for use in shear walls, enhancing the performance of low-performing wall designs without compromising safety or code compliance.

Backed by decades of proven results, the RSIC™ family of products represents the most cost-effective way to achieve consistent, professional acoustic isolation across a wide range of construction scenarios.
