Abstract
A flame resistant insulation product comprises a fibrous mineral material that has been rotary fiberized, preferably a fibrous glass. The composition of the mineral material has a softening point of at least about 699° C. An insulated duct includes a tubular wall that defines a hollow interior for conducting a fluid, and a layer of the insulation product wrapped about the wall. The mineral material reduces the number of samples of the insulated duct failing the flame penetration test of a UL 181 Standard compared to the same insulated duct with a mineral material having a softening point of less than 699° C.
