Saving Energy in Supermarkets with Vacuum-Insulated Glass

Vacuum-insulated glass offers outstanding performance with an airless space just ¼ mm thick. It’s finally coming to windows but already here for cooler doors.

November 5, 2018

A vacuum is a near-perfect insulator, making vacuum-insulated glass (VIG) a tantalizing option, and a commercially available R-10 replacement for single-pane windows is finally within reach. In the meantime, Guardian Glass already has a substantial market for this miracle glass—in supermarket display cases.

Anthony’s Vista Elite series of display case doors are a VIG option within the company’s “optimized merchandising” Vista line. This line consists of all-glass doors to maximize visibility into the cooler. Although neither Guardian nor Anthony advertise this fact, BuildingGreen learned that the Vista Elite line uses Guardian’s VIG units.
