Abstract: Fanfold thermal insulation and method of manufacture includes an elongated generally planar web comprising a plurality of generally planar sheets of non-fibrous thermal insulation material. A plurality of connectors are positioned at an interface between adjacent edge portions of two of the sheets. The connectors hold the two sheets together in a particular rotational relationship that allows rotation of the sheets about an axis generally coincident the adjacent edge portions of the sheets. The particular rotational relationship allows rotation between a first orientation in which the sheets are in facial contact and a second orientation in which the sheets are generally aligned in a plane. The connectors comprise at least two hinges defined by a continuous portion of the thermal insulation material spanning the sheets and a disconnected extent of the adjacent edge portions that is between the hinges. The adjacent edge portions are substantially disconnected at the disconnected extent.
