The invention relates to a vacuum gap insulating element having a spacer (10) for maintaining the vacuum gap between two arbitrarily shaped, quasi-parallel bounding plates (14a, 14b). The spacer comprises a core (12), which has a thermal conductivity of 0.005 W/mK or less in the evacuated state, and a gas-permeable shell material (11), which holds the core together against the air pressure. |
