Yes considerably more.
Although Low Emissivity Glass is used in most Glass Top Freezers, when compared to an Insulated Foam Doors they let a lot more heat enter the cabinet. To compensate for the continuous and increased heat load, Freezer manufacturers use approximately 50% larger compressor than they use in similar capacity Hard Tops. Compressors in Glass Tops work for approximately 50% longer than they work in Hard Tops.
A microscopically thin layer of metal oxides are vapor deposited over clear glass to make Low E Glass. This oxide layer causes the glass to reflect back a considerable amount of heat when compared to clear glass.
