THERMAFLEX® M-KE R4.2 12 Acoustical Insulated Flexible Air Duct, 12 in Dia, 25 ft L, R4.2, -1 to 10 in-WG

The M-KE acoustical duct offers exceptional sound control. Its acoustically-rated chlorinated polyethylene (CPE) core allows sound energy transmission through the core and insulation and into the plenum space. A highly efficient, self-extinguishing duct, the M-KE is suitable for use in all pressure heating and cooling systems.

THERMAFLEX® Acoustical Insulated Flexible Air Duct, M-KE Series, 25 ft Length, 12 in Diameter, -1 to 10 in-WG, Fiberglass/Steel, R-Value: R4.2, 5000 fpm Velocity Rating, -20 to 250 deg F, 0.05 Vapor Transmission

• 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 of damage to vapor barrier
• Uniquely constructed core will not unravel when cut
• All components are self-extinguishing and will not support flame
• 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
