Manufacturing method for a vaccum heat insulator

摘要: A vacuum heat insulator small in limitation shape of applicable objects, and wide application is presented. formed a plurality core members thickness 5 mm or less made glass fiber shaped nearly regular octagonal shape, being coated with gas barrier enveloping member evacuated side. The are octagon, disposed lattice layout at specified intervals so as to form folding lines four directions vertical, lateral oblique 45-degree directions, parallel each In order that the may be located independent spaces individually, entire surface around seal parts, it foldable flexible. By cutting parts along leave about 3 periphery, any desired effective insulating area can obtained. complicated shapes through-holes formed, insulators very scope purposes
