The present invention relates to a ventilation device for ventilation of a building with a double-window construction with an air space, wherein the device communicates with the air space and has at least a first throttle, a second throttle, a third throttle, ad a fourth throttle, wherein the first and the second throttles are able to selectively cut off the passage of air from the air space and into a first and a second chamber, respectively, of the device; wherein the third throttle is able to selectively cut off the passage of air from the first chamber and into the building; and wherein the fourth throttle is able to selectively cut off the passage of air between the open and the first and the second chamber; temperature-sensitive actuators for actuation of the throttles, whereby the air from the space will, in case of increasing temperature within a first low range of temperatures of the air in the air space, to an increasing extent be conveyed into the device via the first and the second throttle and on into the building; and temperature-sensitive actuators for actuation of the throttles, whereby the air will, in case of increasing temperatures within a second range of temperatures of the air in the air space 5/the flow passage 17, above said first temperature range, be conveyed from the space and out into the open by closure of the second throttle and the third throttle and opening of the fourth throttle, simultaneously with air from the open being allowed to flow into the second chamber via the fourth throttle. Hereby a ventilation device is accomplished, whereby, in particular circumstances, it is possible to regulate the amount of air and the temperature in the air space of the window and hence of the room in the building, as it is hereby ensured that a certain amount of air is supplied to the room of the building.
