FireMaster® Fire Protection Products

PlenumWrap®+ Plastic Pipe and Cable System Fire Protection

Product Description

Building Codes require that materials exposed within plenums shall have a flame spread index of not more than 25 and a smoke developed index of not more than 50. Many plastic pipes and plastic coatings on electrical cables do not meet these requirements. Thermal Ceramics FireMaster PlenumWrap+ is a thin, lightweight, and flexible wrap material tested and laboratory listed to UL 1887, NFPA 262 (UL910), and ASTM E84 to reduce flame spread and smoke development of plastic pipe and plastic insulated copper cable installed in environmental air spaces (plenums).

PlenumWrap+ core blanket is manufactured using Thermal Ceramics' patented Superwool fiber, a 2000°F rated, non-combustible, alkaline-earth silicate wool with low biopersistence. PlenumWrap+ is OPL (Intertek) Listed, and is part of both OPL's and UL's Listing and Follow-up Service Programs to ensure the consistent quality essential to the critical nature of this life-safety application.

Product Features

  • Approved to reduce flame-spread (<25) and smoke development (<50) of plastic components in air plenums
  • Thin and lightweight at 1/2" thick, 8 pcf density
  • Contours easily to complex pipe and cable installations
  • Fully foil encapsulated for fast and clean installation and to minimize dusting in return air plenums
  • Easy to install using 1" overlaps and banding or wire ties to fasten
  • Fill blanket is completely inorganic and non-combustible
  • Contains 2000°F rated fibers for added security versus mineral wool or fiberglass fibers
  • Resistant to mold growth at conditions of 75 – 95% relative humidity (ASTM D6329)
