fibreglass insulation

Analyses possible biocontamination of fibreglass duct materials used for thermal insulation and noise control in both residential and commercial heating, ventilation and air conditioning systems, in the light of concerns about the safety of their use in high humidity conditions. Static environmental chamber tests were carried out over six weeks to investigate conditions which might support the growth of a fungus, Penicillium chrysogenum.

In the confusing world of insulation materials, telling the difference between fraudulent claims and the real thing is not easy.
