Zusammenfassung:METHODS OF INTERNALLY INSULATING A FLUTED CORE SANDWICH STRUCTURE A method of partially insulating an interior space of a pre-formed fluted core panel (100) is disclosed herein. The fluted core panel includes a first facesheet (110), a second facesheet (112) spaced apart from the first facesheet, and webs (114) between the first facesheet and second facesheet. The interior space (124) is defined between the first facesheet, the second facesheet, and adjacent webs. The method includes positioning (214) a spacer (134) in a first portion of the interior space (124), positioning (216) a membrane (136) between the spacer and a second portion (139) of the interior space (124), and positioning (218) insulation (120) in the second portion (139) of the interior space (124). Additionally, the method includes pressing (228) the membrane (136) against the spacer (134), curing (230) the membrane (136), and removing (232) the spacer (134) from the first portion (138) of the interior space (124).
