Abstract: A method of insulating a member, such as a cryogenic tank, pipe, or other cryogenic or extreme temperature element with multilayer insulation, and a packaged multilayer insulation blanket for use in the method. The packaged blanket includes (1) a multilayer insulation blanket including a plurality of alternating layers of aluminum or other heat-reflective foil and microfiberglass insulation spacer material, and (2) two layers of plastic sheeting sandwiching the multilayer insulation blanket therebetween. Each layer of plastic sheeting has at least one edge which is sealed to thus define an evacuated inside space containing the multilayer insulation. In the method, the edge of the packaged insulation is opened and an edge of the multilayer insulation blanket therein is attached to the cryogenic tank, container or other member to be insulated. The multilayer insulation is then guided onto or around the member, and out from between the plastic sheeting until edges of the multilayer insulation abut.

Abstract: An improvement of the conventional method of wrapping cryogenic insulation around an inner tank disposable within an outer tank of a cryogenic tank system, where cryogenic insulation paper is unrolled from a roll thereof, wrapping the paper in serially disposed wraps around the inner tank, unrolling cryogenic insulating metal foil from a roll thereof and wrapping the foil in serially disposed wraps onto respective serial wraps of the paper. In the improvement there is provided at least one combined roll of cryogenic insulation having alternating combined layers of the paper of a defined first width and foil of a defined second width wherein the defined second width is less than the defined first width and the foil is centered on the paper so as to provide edge portions at each edge of the paper which are not contacted by the foil. Lengths of combined layers are unrolled from the combined roll, and the lengths of combined layers are serially wrapped around the inner tank.
