The present invention relates to a double-layered insulation glass door system and, more specifically, includes: a double-layered insulation glass door frame which is built in with a blocking medium for blocking heat, and which is made of double-layered glass instead of tempered glass so as to minimize the heat transfer between the indoor and the outdoor; and an attached air curtain which minimizes the loss of heat by inhaling and exhaling compressed air through air nozzles, formed on a double-layered glass door member, blowing the air to every direction from a door frame. |
