M-KE Features and Benefits:

• Underwriters Laboratories UL 181 listed, and complies with NFPA Standards 90A and 90B.
• 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.
• Acoustically rated CPE core assures quiet performance.
• 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.
• CPE core material will stretch over fittings providing a “snug” fit and reducing labor costs associated with a poor fit.
• CPE core will not “blow-out” and eliminates costly call-backs.
• Labor savings and reduced waste result in lower installed costs. Pioneer maintains an inventory of M-KE Insulated Duct and list:
