Duct board releases fiberglass particles into the airstream, this is obviously a health hazard. Mold is another huge problem. The original product deteriorated rapidly and I have found samples where little more than the paper was left upon removal. In recent years manufactures have improved the product by adding thicker coatings inside and mold resistant chemicals. Cleaning is still a problem. It is now a better product, however fibers are still released, how much greatly depends on the installer's methods. Because it of its relative simplicity to on site fab, many unqualified installers are out in the market doing sloppy work. Some trained installers still do not fully understand the importance of sealing all fibers. I have even seen installers who do radius fittings by making little slices so it will bend. RADIUS FITTINGS ARE NOT FOR DUCT BOARD!!! Everyone out there doing this-PLEASE STOP. You are releasing fibers for people to breathe and trapping dirt,spores,germs ect. The cleanest healthiest way to move air is in metal duct with insulation on the outside. Remember "Cheap ain't Good and Good ain't Cheap.
