PlenumWrap ® + Plastic Pipe and Cable System
1. 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 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 2192°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
inch 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 2192°F (1200°C) rated fibers for added security versus
mineral wool or fiberglass fibers
• Resistant to mold growth at conditions of 75 -95 % relative humidity
(ASTM D6329)
• Uneffected by oil or water
• Does not lose fire performance capabilities with age
• Available in 48 inch widths for less joints and installation labor
2. Applications
• PVC Pipes • CPVC Pipes • PP Pipes
• PVDF Pipes • ABS Pipes • PB Pipes
• PE Pipes • Electrical Cables
