Abstract
A freight insulating system for either temporarily retrofitting a conventional uninsulated freight container or insulating cargo transported on individual pallets is provided. When retrofitting a container, a plurality of individual insulation support members are selectively attached to the interior walls of the freight container and a multi-layer insulated bag is attached to and is suspended from the support members, covering and surrounding the freight cargo. When fashioned out of a cross-linked polyethylene foam, the support members provide heat insulation capability as well as spacing the insulating bag a distance from the interior container surface, creating an insulating layer of air while simultaneously providing the requisite minimum air space for the reflective foil layer (described below) to perform at its maximum thermal efficiency. Additional insulating enhancement is provided by constructing the bag out of individual insulating blankets, each of which being fabricated out of two layers of a closed-cell polyethylene material laminated together, with a layer of reflective foil attached to the blanket surface that faces the container wall. These individual blankets are th…
