A unidirectional valve for venting moisture from a window having at least two panes or lights, the panes or lights defining an air space therebetween, is provided. The valve includes: an elongated body having an interior passage formed lengthwise therein, wherein at least a portion of the elongated body is adapted to be inserted directly through a window pane and into the air space formed between the panes; at least one resilient plate pivotally connected to the elongated body; wherein the resilient plate moves in response to changes in fluid pressure within the air space formed between the panes of the window, and wherein the movement of the plate opens the interior passage for allowing moisture-laden air to pass therethrough and out of the air space or closes the interior passage for preventing air from flowing back into the air space between the panes.
