Claims22
A pipe insulation comprising:
- an elongated hollow cylinder of insulation material with a thickness t, the thickness extending from an inner surface of the cylinder to an outer surface of the cylinder,
- wherein a plurality of regions are defined through the thickness t, each of the regions being concentric relative to a central axis of the elongated hollow cylinder,
- wherein a property of the pipe insulation in a first region of the cylinder differs from the property of the pipe insulation in a second region of the cylinder,
- wherein at least one of the first region and the second region comprises a plurality of adjacent layers of the insulation material, each of the adjacent layers having the same property and each of the adjacent layers being a nonwoven fiberglass mat having a thickness less than 0.5 inches and an area weight less than 0.08 lb/ft2, and
- wherein a lengthwise slit extends through the thickness of the pipe insulation.
