The invention relates to a method and air curtain for re-stricting heat transmission through a wall opening (120). Using the method according to the invention, an air curtain restricting heat transmission will be formed in front of the door opening. In the method on the first edge of the open-ing a blowing air flow going through a blow nozzle (12) is formed using a blower (20), and on the other edge of the opening a sucking air flow going through the suction open-ing (16) is formed. Advantageously the blowing air flow is formed at the lower edge of the opening and the sucking air flow at the upper edge of the opening. In this way, an air jet (40) will form in front of the door opening going from the blowing nozzle to the suction opening, and induced flows (42, 44) of air will form on both sides of the air jet, together forming an air curtain. The flowing of air through the door opening between the air jet and the vertical edges of the opening is reduced by side wallings (32). In the invention the induced air flow formed adjacent to the air jet is reversed back to the direction it came from in or-der to form a back flow (46) using an air deflector (30) placed on the other edge of the opening. The induced air flow and back flow form a circulating air flow alongside the air jet, with the temperature of the air mass being higher than the outside temperature. Because of the reduced temperature difference, the amount of heat moving through the opening is also reduced. Operation of the air curtain is controlled by an automatic control device (26).
