Technician applying an Anti-Microbial Coating product to deteriorated insulation.

In many air conveyance systems, internal insulation lining is installed in the ductwork and in the air handling unit for insulation, or sound attenuation purposes. Over time, depending on the environment, this fiberglass insulation will deteriorate. The resulting fibers are distributed throughout the air conveyance system and add to the accumulation of particulate debris within the system. Eventually, these fibers are blown into an occupied space and are found as black specks on surfaces throughout a room. Fiberglass insulation can be an eye, nose and throat irritant, and may result in discomfort to the occupants of a room.

Fiberglass insulation that becomes wet due to condensation, or water leakage, also may result in microbiological growth within the ductwork and again, may cause discomfort to the occupants of a room serviced by that air conveyance system.

Insulated ductwork can be cleaned utilizing NADCA (National Air Duct Cleaners Association) standards, and NAIMA (North American Insulation Manufacturers Association) recommended practices.

In many cases, after cleaning, insulated ductwork can be treated with a Coating product designed to encapsulate and “lock-down” the deteriorated fibers. These coating products are specifically designed for HVAC duct systems and provide a new surface and extend the life of the insulation. Many of these coating products contain Anti-Microbial additives which help to inhibit future mold and microbial growth.
