The door has a revolutionary design where treated air is emitted into the space between the two curtains, creating an effective insulation layer that prevents temperature transfer. This works on the same principle as double-glazed windows, which use two panes of glass with a sealed gap between them to reduce heat transfer and improve energy efficiency.
