Vented protective panel for glazing

A window unit adjacent to an air space having an external air humidity, the window unit comprising:

• (a) a window frame that defines a void therein and that has a front panel and side panel, the void in communication with the air space through a plurality of external air vents in the front panel, and the side panel defining a plurality of side panel holes;
• (b) at least one glazing unit supported by the window frame;
• (c) a security panel spaced apart from the glazing unit and defining an air cavity there-between that has an air cavity humidity;
• and
• (d) a rectangular securing structure that is affixed to the window frame and to which the security panel is affixed, the rectangular securing structure including a rectangular first vertical tubular bar, an oppositely disposed rectangular second vertical tubular bar, a rectangular bottom tubular bar and an oppositely disposed rectangular top tubular bar, the rectangular securing structure disposed in the air cavity, at least one of the first vertical tubular bar and the second vertical tubular bar defining a passage therethrough that is in communication with the air cavity through a plurality of air cavity vents and defining a plurality of passage holes that are each aligned with a different one of the plurality of side panel holes so that the passage is in communication with the void therethrough, so that air circulates from the air cavity to the air space through the plurality of air cavity vents, the plurality of passage holes, the plurality of side panel holes and the plurality of external air vents, thereby maintaining the air cavity humidity at the external air humidity.
