Security Window Assembly

A security window assembly comprising:

• a frame coupled to an opening in a structure;
• a first window section coupled to the frame;
• a second window section slidable within the frame relative to the first window section, the second window section having:
• a closed position where the first window section and the second window section substantially fill different portions of the opening;
• and
• an open position where the first window section and the second window section substantially fully overlap each other;
• and
• a security panel coupled to the second window section so that the security panel is stowed within the structure when the second window section is in the closed position and at least partially fills the opening when the second window section is in the open position.

A security window assembly comprising:

• a frame defining a frame opening;
• a first window section secured to the frame and occupying a first portion of the frame opening;
• a second window section slidably secured to the frame and slidable relative to the first window section, the second window section having:
• a closed position where the second window section occupies a second portion of the opening different from the first portion of the opening with the first window section and the second window section substantially filling the entire frame opening;
• and
• an open position where the first window section and the second window section substantially overlap and occupy the first portion of the frame opening;
• and
• a security panel coupled to the second window section so that the security panel is outside of the frame when the second window section is in the closed position and at least partially fills the second portion of the opening when the second window section is in the open position.
