Abstract:
1. A vacuum insulating glass (VIG) unit comprising: first and second substantially parallel spaced-apart glass substrates, including edge portions thereof; at least one metal strip located between the substrates and proximate to the edge portions of the substrates, the at least one metal strip having a coefficient of thermal expansion so that the coefficient of thermal expansion of the at least one metal strip and a coefficient of thermal expansion of the glass substrates do not differ from each other by more than about 25% over a temperature range of from about −40° C. to about 50° C.; wherein the first and second substrates are sealed together proximate to the edge portions thereof via the at least one metal strip and an edge-sealing material provided proximate the at least one metal strip and the first and second glass substrates; and wherein the at least one metal strip is spiral shaped so as to include multiple folds and at least three substantially coplanar portions at different planes between the glass substrates, and wherein the at least one metal strip is provided between only the first and second substrates and not between any other glass substrate(s).
