Abstract
A ducting system for a heating ventilation and air conditioning (HVAC) application includes a duct assembly having an inner duct member, and an outer duct member disposed around the inner duct such that the outer and inner duct members together define a pre-determined amount of space therebetween. The ducting system also includes a bonding and insulation composite that is disposed in the pre-determined amount of space between the inner and outer duct members to insulate the inner and outer duct members from each other yet adhesively bond with each of the inner and outer duct members for imparting structural rigidity to the duct assembly.
