Abstract
A vacuum insulating panel includes first and second substrates (e.g., glass substrates), a hermetic edge seal, a pump-out port, and spacers sandwiched between at least the two substrates. The gap between the substrates may be at a pressure less than atmospheric pressure to provide insulating properties. The vacuum insulating panel may include at least one passivation layer for reducing outgassing from a glass substrate, in order to improve lifespan of the vacuum insulating panel.
