Fiberglass Roving & Silent Packs

ISW SILENT PACKS are used for packing internal exhaust / muffler components, auto compartments/cabins or even residential cinder blocks to provide excellent long term sound absorption.  SILENT PACKS are made from a continuous filament, single-end roving product manufactured with boron-free modified E-Glass (E-CR) composition fibers.  ISW’s Fiberglass E-CR Roving is engineered to provide excellent sound absorption in high temperature and corrosive exhaust systems.

FEATURES / BENEFITS OF ISW ROVING:

• ISW’s E-CR Fiberglass Roving is OEM approved and Made in the USA.
• The sizing chemistry of the individual fibers produces pillows that are uniformly volumized with a lofty roving that has low fuzz and fly for efficient long term acoustical performance.
• Has higher thermal and better chemical durability than basalt or standard e-glass.
• Is less sensitive to high humidity versus other leading E-CR roving.
• Increased fiber strength over both basalt and standard E-glass fibers even at elevated temperatures.
• Reduces opportunities for shell corrosion caused by fiberglass mat.
• Is designed to easily open to provide uniform and effective acoustic properties.
