Abstract
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.
