A defense structure and methods of use for penetrating the defense structure with a projectile from a first side and preventing a projectile from penetrating the defense structure from a second side. The defense structure comprising a plurality of wedges arranged to rotate and abut each other using a tensioning member, such as a spring. Ballistic and resilient members are provided on a rear surface of the plurality of wedges to prevent a projectile from penetrating the defense structure through deflection and/or adsorption of the projectile. A gap is formed between at least two of the plurality of wedges when a projectile is urged between the plurality of wedges from the first side. The tensioning member urges the plurality of wedges to rotate and abut each other after the projectile passes through the gap. The defense structure may be partially concealed within a structural element.

The technology provides an improved louvered panel assembly having a louver panel with at least a first louver and a second louver and a pivot bar that extends therebetween. A control arm is secured between the pivot bar and an operator to rotate the louver panel between open and closed positions. The first and second louvers include a central receiver that receives a first bearing surface to rotate the louvers about a rotational axis extending therethrough. A leading projection extends from the first louver and is rotated downward as the first louver operates between open and a closed positions. A trailing projection extends from the second louver and is rotated upward as the second louver operates between open and a closed positions. An elongated track is positioned below the louver panel and is spaced from the louver panel by a flap structure having a sealing membrane.

A shutter assembly including a plurality of shutter panels arranged side-by-side. Each shutter panel has a respective plurality of louvers and a respective operable tilt mechanism configured to adjust the tilt angle of the respective plurality of louvers. A control shaft operates the tilt mechanisms. The control shaft is configured to drive simultaneously the respective tilt mechanisms of all of the plurality of shutter panels.

A window replacement panel including an air conditioning vent incorporated into it. A window assembly may be attached to a decorative panel with a vent disposed on a first side, and a coupling for an AC duct on an opposite side. The window may be a single, double pane, insulated, uninsulated or the like. The panel may be clad with material to harmonize with the building exterior, and the exterior vent presents a pleasing appearance. The combination of window and panel may be sized to replace an existing window, or may be used in new construction.

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. The louver further includes an elongated member disposed within the frame and in contact with the plurality of louver blades. The elongated member has a body that longitudinally extends between a first member end and a second member end, wherein the first member end and the second member end are fixedly connected to opposing sections of the frame. The described louver may provide improved wind-driven rain resistance and/or impact resistance.

A louver assembly for placement in an opening for regulating the inlet of air, comprising a first blade stack and second blade stack arranged in tandem, and a sill for supporting the first and second blade stack. The first and second blade stacks have a plurality of blades arranged in a horizontally-spaced and vertically-extending configuration defining a plurality of horizontally-spaced and vertical extending air passageways for the passage of air therethrough. The sill has a generally planar first portion for supporting the first blade stack and a sloped second portion for supporting the second blade stack, wherein the sloped portion and the second blade stack define therebetween a void for equalizing pressure within the assembly to facilitate the draining of water therefrom.
