Abstract
An insulation structure for a pressure vessel cavity is described in which a layer of fibrous insulation along the cavity wall is isolated from the remainder of the cavity to prevent circulation of fluid in the layer. Isolation is accomplished by means which define a gas flow space. Retaining means for the layer define a plurality of fluid passages communicating with the layer and allowing venting of the layer into the gas flow space upon depressurization of the cavity.
