1. A flexible insulation comprising:
an insulating material having a thickness between 3/16 and ⅜ inches, the insulating material including a closed cell polyolefin foam;
a reflective covering material positioned over the insulating material, the insulating material having a side that is directly or indirectly adjoined to the reflective covering material; and
a plurality of punched holes, wherein each of the plurality of punched holes has an initial diameter of at least 1/16 inch and extends completely through at least both the insulating material and the covering material, at least some of the plurality of punched holes having a spacing of about one inch between adjacent ones of the plurality of punched holes, wherein formation of the plurality of punched holes removes material in the form of the punched holes from the flexible insulation.
