Vacuum Glass for Freezer & Cold Room Doors
Vacuum Glass for Freezer & Cold Room Doors
Commercial-grade VIG for refrigerated and frozen display cabinets, walk-in cold rooms and supermarket cold-aisle doors. Eliminates the heating elements traditionally used to prevent condensation — saving 80%+ of door-frame electricity costs.
Trent Glass Vacuum Glass for Freezer & Cold Room Doors is a specialist VIG product engineered for refrigerated and frozen display environments. The exceptional U-value (0.5 W/m²K) prevents condensation on the warm-side surface without the need for traditional perimeter heating elements — typically saving 200–500 W of continuous power per door. Specified by major UK supermarket chains and cold-chain logistics operators.
