Abstract
The present disclosure relates generally to duct liner insulation products for curvilinear ducts, and more specifically relates to methods and materials to universally fit duct liner insulation for lining oval ducts in air conditioning, heating, and ventilating (HVAC) systems. A duct liner insulation for a curvilinear duct is provided that includes an insulation layer configured to line an interior surface of a curvilinear duct when installed within the curvilinear duct. The duct liner insulation also includes an elastically deformable layer configured to compress the insulation layer against the interior surface of the curvilinear duct when installed within the curvilinear duct such that the insulation layer extends substantially uniformly around an inner periphery of the curvilinear duct.
