PURPOSE: An air curtain is provided to minimize problem on view and lighting by using light-transmissive material and reduce the loss of heat emitted through a window or a veranda window of a building. CONSTITUTION: An air curtain comprises an outer sealing line(13), an air inlet(14), a joining wire(15), and adhesive material. The outer sealing line vertically folds an outer plastic film and an inner plastic film and seals the outer circumference. The air inlet is formed on the lower part of the outer sealing line. The joining wire is formed to maintain an air curtain in a flat shape. The joining wire attaches the outside plastic film and the inner plastic film inwards an outer sealing line at fixed intervals. The adhesive material is spread on the window junction of the inner plastic film. |
