Abstract The paper discusses the susceptibility of fiberglass duct liner to fungal (Penicillium chrysogenum) growth. Three fiberglass duct liners, one of which contained a bound biocide. Were tested using a recently developed method for evaluating fungal resistance. Each sample was inoculated with P. chrysogenum and incubated in a static chamber controlled at 97% relative humidity (RH) and 21 C for 6 weeks. Culturable spores on each sample were enumerated before and after incubation to determine the extent of fungal growth. The results indicated that newly purchased fiberglass duct liner samples, as received from local vendors, have different fungal resistances. No amplification of the P. chrysogenum was detected on two of the three liners tested; however, significant fungal growth was detected on the third. Wetting the samples with sterile water enhanced the susceptibility of two of the liners to fungal growth, but not the third. However, soiling the samples with dust collected from residential heating and air-conditioning systems significantly enhanced the susceptibility of all three liners to fungal growth. Even the fiberglass duct liner containing biocide supported fungal growth after soiling.
