摘要

Window with a window frame to be built into a building wall and casement arranged therein, at least one insulating glass unit being inserted in the casement. Positioned on the casement on the inside of the room is a front frame which is equipped with at least one glass pane and which forms a chamber-like transmission trap towards the insulating-glass unit. The casement has below the insulating-glass unit a device for introduction of outside air into the transmission trap and above the insulating-glass unit a device for outlet of the outside air introduced out of the transmission trap into the associated interior. <IMAGE>
