The Performance of Glass Fiber Insulation under High Vacuum

Abstract

The recent evolution of the small laboratory cryogenic system into the fully engineered industrial cryogenic plant places new demands on the performance of materials of construction. Equally important to the design engineer, however, is the availability of accurate design data for these materials, In the field of thermal insulations, for example, new high efficiency products are becoming available to meet present day needs, but good design data remain scarce. For insulating materials, the data needed are the apparent thermal conductivities under the conditions of application.
