Abstract
A building and/or light element includes at least two parallel wall elements (1) between which support elements (2) for the formation of an evacuated interspace (3) are placed and are connected by a flexible seal on the edge. The distance between the wall elements (1) is less than 0.5 mm and the support elements (2) are formed as disks lying flat between wall elements (1). The production and application of support elements (2) occurs with a punching device placed over the gridlike predetermined distribution surface of wall elements (2).
Claims9
A process for the production of a heat-insulating building and/or light element comprising the steps of positioning a plurality of flat support elements (2) between at least two substantially parallel wall elements (1) to space the wall elements a predetermined distance apart, applying a metallic foil seal to the edge areas of the spaced wall elements to form a tight bond therebetween so as to define an evacuable interspace (3) therebetween and to absorb any differences in expansion of the wall elements resulting from differences in the temperatures of the wall elements, evacuating the interspace to a vacuum between 1 and 10.sup.-2 mbar, the distance between the wall elements being smaller than the free path lengths of air molecules as determined for that vacuum such that the heat conductivity of the air molecules between the wall elements is substantially cancelled.
