Air Distribution System Ducts

Air Distribution System (ADS) Ducts, require a high temperature blanket specifically designed to provide one and two-hour fire ratings around fire rated ventilation ducts. This flexible, fire protection wrap meets the requirements defined by the Mechanical Code and is an alternative to a traditional fire-rated shaftwall enclosure around ducts. It is used to wrap HVAC ducts, stairwell pressurization ducts and smoke extraction ducts and provide critical fire protection and life safety.

FyreWrap® Elite® 1.5 Duct Insulation

Unifrax’s FyreWrap® Elite® 1.5 Duct Insulation is a single layer flexible duct wrap enclosure for 1- and 2-hour fire-rated air distribution systems (ADS ducts). Typical duct types include smoke control, hazardous exhaust, laboratory chemical fume, stairwell and vestibule pressurization, ventilation, supply/return ducts, commercial dryer exhaust, as well as refuse and linen chutes. This slim, compact design is an alternate to code prescribed fire-rated shafts and results in significant weight, space and labor savings when compared to traditional shafts.

FyreWrap Elite 1.5 Duct Insulation Air Distribution System (ADS) offers the following features:

  • 1- and 2-hour fire-rated enclosure (3 hour available)
  • Alternate to fire-rated shaft
  • Zero clearance to combustibles at all locations on blanket wrap
