CONDENSATION-FREE FREEZER DOOR ASSEMBLY

摘要

A freezer door assembly with a viewing area and that requires no electric heating source to maintain the assembly free from condensation under standard conditions. The assembly includes inner and outer spaced parallel glass panes and a panel spaced between the panes, the panes and panel having confronting surfaces of which at least one is provided with coatings highly transmissive of visible light and highly reflective of long-wave infra-red radiation. The assembly includes an insulating frame at the edges of the panes, the frame having sufficiently low thermal conductivity as to in turn maintain outer surfaces of the frame and outer pane free from condensation under standard conditions.
