HVAC Duct Insulation

To insulate ductwork around HVAC systems in older homes and buildings' basements and attics, asbestos paper was often utilized as a duct wrap insulation material. This material frequently contains chrysotile asbestos at a concentration of approximately 15%. Other asbestos-containing materials, such as asbestos cement, millboard, and insulation, were employed in the construction of HVAC systems.

How can I tell whether the duct wrap I'm using contains asbestos?

Asbestos duct-sealing tape will have the appearance of a thick white fabric tape that has been wrapped around the joints. A sheet of asbestos was frequently affixed to the ceiling above a boiler or furnace to provide insulation. You should avoid touching it if it is in good condition. If the material is "friable" and appears to have the potential to become airborne, there is a problem.

What type of material is used in the construction of HVAC ducts?

Galvanized steel is the most often encountered material in the production of ducting. Steel ductwork expands and contracts as a result of the heat and cold it receives.

When was asbestos utilized in ducting and how long did it last?

Heating ducts that were erected before the 1980s were insulated with asbestos, which is now known to cause a cancer called mesothelioma in its victims. Mesothelioma is an extremely aggressive disease that is caused by either direct or indirect exposure to asbestos. It is extremely difficult to treat.
