FEATURES AND BENEFITS:

• Underwriters Laboratories UL 181 and CUL S110 listed, and complies with NFPA Standards 90A and 90B.

• Acoustically rated resilient calendered film core assures quiet performance.

• Core material will not support mold and mildew growth.

• Fully lined for efficient air delivery.

• Large diameter, heavy, spring steel wire helix assures dimensional stability, resists mechanical abuse and provides more efficient air delivery.

• Bi-Directional reinforced metallized jacket resists tearing— reduces chance for damage to vapor barrier.

• Uniquely constructed core will not unravel when cut.

• All components are self-extinguishing and will not support flame (see oxygen index figures under application and engineering data).

• “Outward Cast” of heavy spring steel helix keeps duct core from shrinking up inside insulation and jacket, resulting in less waste.

• Resilient calendered film core material will stretch over fittings providing a “snug” fit and reducing labor costs associated with a poor fit.

• Resilient calendered film core will not “blow-out” and eliminates costly call-backs.• Labor savings and reduced waste result in lower installed costs.

• Available through broad national distribution.

• Meets California Department of Health Standards - OSHPD.

• GreenGuard Certified for children and schools.

• State of Florida AHCA approved.
