Title: Method of manufacturing heat insulating structural and/or light elementsand installation for carrying out the method

Abstract: A method of manufacturing heat-insulating structural and/or light elementscomposed of at least two wall elements of glass, a glass alloy or metal,wherein the wall elements are separated from each other by supportelements and are provided on at least one of surfaces thereof facing eachother with a layer reflecting heat radiation, and wherein the structuraland/or light elements further are composed of a deformable sealing elementfor connecting the wall elements to obtain a hollow space between the wallelements which can be evacuated or supplied with gas. The method includesconveying wall elements which have been cleaned and coated on at least onesurface thereof and are intended for a structural and/or light element ina manufacturing line extending over manufacturing sections, coating withsolder at least one side of each wall element at edges thereof, placingspaced-apart support elements on a wall element, positioning the wallelements opposite each other at a distance determined by the supportelements, and subsequently enclosing the wall elements to form a gas-tighthollow space between the wall elements by applying a deformable metalsealing element at the coated edges of both wall elements.
