Production of evacuated insulating elements, e.g. structural panels for refrigerators, involves enclosing rigid foam core or support in airtight foil, bonding core or support to foil with adhesive and evacuating foil

摘要

A method for the production of evacuated insulating elements with a core or supporting part (preferably of rigid, open-cell foam) enclosed in an airtight, evacuated foil, in which the foil is bonded with the core or supporting part by means of an adhesive.
