Abstract
An insulating vacuum panel comprising an insulating support member enclosed within a sealed, flexible polymeric envelope, the envelope comprising a polymeric barrier film which minimizes permeation of gas and liquid through the barrier film, the panel having an R value per inch of at least about 20 wherein the enclosed insulated vacuum panel is useful as insulation to maintain an essentially constant temperature in a closed structure, and a system for storing and transporting temperature-sensitive materials wherein the insulated vacuum panels are employed to provide and maintain a constant temperature in the system are described.
