Window mounting assemblies

A security window assembly comprising:

• a frame constructed to extend along at least a portion of an opening defined by a building structure and having a weather resistant window disposed in the opening, the frame having a riser that is oriented to be disposed in a plane of a security window and located radially outboard of the security window and offset from the weather resistant window such that the security window overlies the weather resistant window, a reinforcement flange that extends along a portion of at least one side of the security window, and a mounting flange that extends in a lateral direction from the riser and is constructed to secure the frame to the building structure at a location laterally outboard of the weather resistant window;
• a first opening formed through the riser that defines an unobstructed passage that fluidly connects opposing sides of the security window at a location radially outboard of a perimeter of the security window;
• and
• a second opening formed through the riser that defines another unobstructed passage that fluidly connects opposing sides of the security window at a location radially outboard of the perimeter of the security window and which is vertically offset from the passage defined by the first opening and such that the first opening and the second opening are each circumferentially bounded by the mounting flange, respective adjacent ends of the riser, and an edge of the security window when the mounting flange is secured to the frame of the building structure and vent a space between the security window and the weather resistant window.

A method of forming a security window assembly, the method comprising:

• providing a laminated window pane assembly shaped to overlie a building window opening and a weather resistant window mounted in the building window opening;
• providing a frame assembly that is constructed to cooperate with the laminated window pane assembly and is constructed to define each of a riser that extends between the laminated window pane assembly of the building window opening, a reinforcement flange that extends from the riser in a direction toward the laminated window pane, and a mounting flange that extends from the riser in a crossing direction relative to the reinforcement flange;
• forming a first opening and a second opening through the riser such that each of the first opening and second opening are unobstructed and bounded by adjacent portions of the laminated window pane, the riser, and the mounting flange and extend to opposing sides of the laminated window pane assembly and the first opening is located nearer a bottom of the laminated window pane assembly that the second opening and the second opening is located nearer a top of the laminated window pane assembly than the first opening;
• and
• extending at least one support post through the mounting flange and into engagement with a structure surrounding the building window opening at a location aligned with a respective one of the first opening and the second opening such that the laminated window pane overlies the weather resistant window and the first opening and the second opening vent a space between the laminated window pane and the weather resistant window.
