Spiracoustic is a Johns Manville engineered interior liner for spiral ductwork that is positioned as an alternative to the Double Wall method of Perforated and Unfaced Liner by providing a lighter, easier to install that product that fits tight and secure regardless of diameter with exceptional acoustical and thermal performance. Simply cut the factory grooved board to the diameter you need and slide it in. Factory coated to prevent any fibers in the airstream, but use of JM SuperSeal Coating to recoat any fabrication cuts or installation damage will help to ensure an ideal system installation.
