Abstract
A method is described for the manufacture of a vacuum insulating structure intended mainly, but not exclusively, for use in such domestic appliances as refrigerators or freezers as well as for vehicle walls including aeroplanes and in buildings. A hollow plastic or metal panel is purged to atmospheric air by means of a getterable gas. Vacuum is produced by removing the purge gas and the vacuum is subsequently maintained by contacting the residual gas with a getter material. A vacuum insulating structure thus manufactured is also described.
