Claim:
1. A vacuum insulated glass (VIG) unit, comprising: first and second substantially parallel, spaced apart glass substrates defining a gap therebetween; an edge seal provided around a periphery of the first and second substrates to form an hermetic seal; a plurality of spacers provided between the first and second substrates; a lamellar coating to impart closure stresses on the first and/or second substrates proximate to the spacers to at least partially offset tensile stresses also applied to the first and/or second glass substrates, wherein the first lamellar coating is provided across substantially an entire surface of at least one of the substrates, a second lamellar coating provided so that the spacers are between the first and second lamellar coatings, and wherein the gap is provided at a pressure less than atmospheric.
