Armacell Announces New WIDE WIDTH AP Armaflex® FS Duct Liner and Wrap

Makes installation of insulation for longer ducts quicker and easier.

Chapel Hill, NC – November 1, 2017 – Armacell, a global innovator in foam technologies and a world leader in the market for flexible mechanical insulation materials, announces the introduction of new wider width duct liner. Armacell is now making our closed cell, fiber free AP Armaflex® FS and AP Armaflex FS SA Duct Liner and Wrap insulation in 1-1/2" thickness in wider width 56-1/4", 59" and 60" rolls. Specifiers and contractors can now meet R-6 code requirements while saving time and labor with easy-to-install matching widths that eliminate the need to splice 48" material into longer ducts. 

All of this with the same great thermal performance, noise absorption and condensation control customers have come to expect from AP Armaflex, but now in a width and thickness that provides the R-6 value needed for duct liners and wraps.


  • New 60" width aligns with common lengths of sheet metal ducts
  • Save time with insulation rolls that perfectly match duct sizes
  • Reduce scrap and waste from cutting and piecing together undersized rolls
  • Saves energy with an R-value of 6 that is required by building codes
  • 25/50 rated, in all sizes and thicknesses
  • AP Armaflex FS and AP Armaflex FS SA Self-Adhering duct liner are available made-to-order

Why Use Duct Liner or Wrap?

Mechanical engineers specify the AP Armaflex family of duct liners for its acoustic benefits, attenuating equipment noise that can be bothersome to building occupants. Duct wrap provides thermal protection, preventing heat loss or gain to the HVAC system and saving energy, allowing the system to work more efficiently. Wrapping ducts can also prevent condensation drip from happening on cold ducts that are installed in areas with warmer ambient temperatures.
