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.

Methods and materials to universally fit duct liner insulation for oval HVAC duct systems

The embodiments described herein relate generally to improved fit duct liner insulation for curvilinear ducts in HVAC, exhaust, or other similar gas flow systems. A duct liner insulation for a curvilinear duct may include an insulation board having a first major surface and a second major surface. The duct liner insulation further includes a plurality of rows of kerfs in the first major surface of the insulation board configured to allow the insulation board to flex in a direction of the width of the insulation board such that insulation board is foldable into a curvilinear configuration. Each of the kerfs has a v-shaped cross section with sidewalls extending from a kerf base portion at or near the second major surface of the insulation board to the first major surface of the insulation board. The sidewalls extending at an angle from 10 degrees to 20 degrees relative to each other.
