ICW is engineered for performance, ease of selection, and installation. Full one-inch deflection coils provide acoustic performance across a wide frequency range. Included shop drawings will lay out the isolators utilizing ten different spring coil capacities—ensuring the ceiling is level after construction. The hanger bracket aids installation as it holds the spring in place while fastening gypsum board. ICW’s channel clip fits a typical cold-rolled-channel grid system and allows for leveling. ICW also makes fire ratings easy. A single UL assembly number allows for use of either wood joists, engineered wood beams, or open trusses.
