Armacell AP Armaflex® Spiralflex Through 1" Duct Liner
Categories: Other Engineering Material

Material Notes: Fiber-free, elastomeric duct liner for round ducts. This product is a fiber-free elastomeric duct liner for spiral ducts, considered to be the most efficient ducts made. An easy-to-cut, flexible olefin backing is pre-laminated to the foam and shipped in convenient rolls.
  • Fiber free and easier to clean than fibrous duct lining
  • Good at attenuating airborne noise from HVAC systems
  • Ducts with AP Spiralflex liners are 20% lighter than dual wall ducts. This can translate to cost savings in duct hangers, construction supports and other building costs
  • Simplified one-step installation: Eliminates costly encapsulating films and the inner metal wall for round ducts
  • ASTM E 84 25/50 rated for smoke and flame
