Johns Manville has introduced Microlite Black PSK Duct Wrap. This formaldehyde-free fiberglass duct wrap insulation is adhered to a black-coated poly-scrim-kraft (PSK) facing designed specifically to offer a sleek, sophisticated look. It is recommended for exposed applications inside the building envelop, such as open ceilings with exposed duct work. Now, users can insulate with aesthetics in mind without sacrificing any performance characteristics.
Microlite Black PSK meets the UL requirements for 25/50 flame spread/smoke developed. Matching Black PSK seaming tape is also available
