Abstract
An insulated duct includes an inflatable jacket surround the duct. The jacket is inflated, preferably with air traveling in the duct, to create a static condition in the air space formed by the jacket to provide additional insulation for the duct. When the jacket is combined with additional insulation and low emissivity material, the R value of the duct can be increased in a more efficient manner from manufacturing and cost viewpoints.
