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.

UPDATE, March 30, 2021: Anthony has informed BuildingGreen that it no longer offers vacuum-insulated products. See the comments section for a full statement on the status of vacuum-insulated products from Guardian Glass.

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.
