DESCRIPTION

  • Core material will not support mold and mildew growth
  • Highly resistant to rust and corrosion
  • 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
  • Heavy woven and coated fiberglass cloth core assures quiet performance
  • Uniquely constructed core will not unravel when cut
  • Bi-directional reinforced metallized jacket resists tearing—reduces chance of damage to vapor barrier
  • Core will not deteriorate in a fire until the temperature reaches the melting point of glass
  • “Outward cast” of helix keeps duct core from shrinking up inside insulation and jacket, resulting in less waste
