Abstract
A freight container insulating system for retrofitting, on a temporary or semi-permanent basis, a conventional uninsulated freight container is provided, and consists of a plurality of individual insulation support members selectively attachable to the interior walls of a freight container and from which one or more insulating blankets are attached to and suspend to cover and surround the freight cargo. When fashioned out of a cross-linked polyethylene foam, the support members themselves provide heat insulation capability along with spacing the insulating blanket a distance from the interior container surface, creating an insulating layer of air. Additional insulating enhancement is provided by utilizing as the insulating blanket, 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. The insulation envelope is completed by an insulated floor covering sheet, which may also consist of a closed-cell polyethylene insulating material.
