Thermal insulation PlenumWrap™+

interiorfor ductfireproof

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 Intertek Listed, and is part of both Intertek’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. 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) • Unaffected by oil or water • Does not lose fire performance capabilities with age
