Insulating air ducts helps the control the temperature within the ducts and to prevent the ducts from leaking air, resulting in greater energy consumption and costs. Heat loss through the duct walls is also an expected and inevitable drain on the system. Effective thermal insulation of the ductwork reduces this heat loss and helps to minimize energy usage. 

Cool air passing through warm areas of a building can cause condensation and dripping, which could lead to mold growth, corrosion and multiple safety issues.  Condensation can form on duct surfaces with a temperature either equal to or lower than the dew point. This moisture can become a hotbed for microbial contamination and corrosion.

Without proper air duct insulation, up to 30% of the energy used to heat or cool your facility could be lost.  Air duct insulation can help limit energy waste, leaks, temperature drops, and condensation buildup. A closed cell insulation can help limit moisture ingress than can lead to energy losses, build-up of condensation, and the consequences that go along.
