Abstract

A heat-insulating wall, such as a refrigerator door or housing, includes a substantially vacuum-tight outer paneling, an inner paneling, a substantially vacuum-tight connecting diaphragm formed from material having low heat conduction, a diaphragm cover formed from material having low heat conduction, and a protective profile with an opposite magnetic pole or a magnetic seal. The diaphragm is respectively vacuum-tightly connected to the inner paneling and to the outer paneling at free borders thereof. The outer paneling, the diaphragm, and the inner paneling define an evacuable cavity that is filled with an evacuable supporting material. The diaphragm cover covers at least a part of the diaphragm. The protective profile is secured one or both of the inner paneling and the outer paneling and substantially covers the diaphragm cover.
