Different elevations can cause an insulated glass unit to deflect.
This happens frequently.

Double-pane glass is filled and sealed with air.
Meaning: When sealed at a much lower altitude, and transported to a higher altitude, it may pop.
Conversely, from a higher elevation to a lower elevation, it may deflect inward, which is very bad because deflection makes the glass look bad, unsafe, and may void the warranty.

SuperVIG® Vacuum Insulated Glass is vacuum insulated and is less susceptible to air pressure issues, SuperVIG® Vacuum Insulated Glass is vacuum insulated and is less susceptible to air pressure issues, meaning it won’t have a problem with changing altitudes.
