Abstract

L'invention concerne un panneau isolant à vide comprenant une première feuille 3 ou feuille extérieure, une seconde feuille ou feuille intérieure 4, et un élément de pontage 1 s'étendant entre les feuilles 3, 4. En section transversale, l'élément de pontage 1 présente un aspect ondulé. L'élément de pontage 1 présente des régions de fixation aplanies 2 qui sont utilisées pour lier (par exemple par collage adhésif) l'élément de pontage 1 aux feuilles supérieure et inférieure 3, 4. Les feuilles 3, 4 et l'élément de pontage sont tous constitués de feuilles de matériau flexible et des compartiments 5 définis par les feuilles 1, 3, 4 sont remplis d'un matériau isolant approprié. Un vide est ensuite établi dans les compartiments 5. Les compartiments sous vide remplis d'isolant sont isolés les uns des autres afin que si un compartiment est percé, il n'y ait aucun effet défavorable sur les autres compartiments.
