An exemplary door includes a door body and a light assembly. The door body includes a first door panel defining a first panel opening, a second door panel defining a second panel opening, and an internal cavity. The area of the first panel is greater than the area of the second panel opening. The light assembly includes a first trim, a second trim, and an impact-resistant pane positioned in the door cavity. The first trim includes an outer frame coupled to the first door panel and an inner frame positioned in the internal cavity. The pane has an area greater than the area of the second panel opening area, and includes an first outer layer adhered to the inner frame of the first trim, a second outer layer adhered to the door body, and at least one intermediate layer.

Polymeric interlayers for use in making multiple layer panels having a unique balance of properties are provided. Single and multiple layer interlayers according to various embodiments of the present invention can be used to form multiple layer panels that exhibit both enhanced rigidity and improved impact resistance, while still retaining desirable optical performance. Interlayers and multiple layer panels of the present invention may be particularly suitable for use in a wide range of applications, including, for example, in many indoor and outdoor architectural and structural applications.

A security unit protects a glazing unit supported by a window frame The window frame defines a void that is in communication with an air space through external air vents. The window frame has a side panel that defines side panel holes. The security unit includes a security panel that is spaced apart from the glazing unit to define an air cavity and is secured to a vertical tubular bar that is secured to a side panel of the window frame. The vertical tubular bar defines a passage therethrough in communication with the air cavity through air cavity vents and defines passage holes aligned the side panel holes. Air circulates from the air cavity to the air space through the air cavity vents, the passage holes, the side panel holes and external air vents.

A ballistic garage door assembly and a kit for converting a standard garage door uses sheets of ballistic material secured to the exterior shell of the standard garage door panels along with inserts at the joints between adjacent garage door panels. Joint inserts applied to the horizontal ends of the garage door panels provide bullet resistant characteristics at the joints. Aluminum sheets with multiple plies of ballistic material between the aluminum sheets are applied to the entire garage door shell. Insulated foam is place on the innermost aluminum sheet to provide additional ballistic performance for the converted garage door. Increased levels of ballistic protection will utilize thicker aluminum panels and an additional external ballistic bumper to increase ballistic performance of the joints between the garage door panels. The outward aesthetic appearance of the garage door does not change appreciably, although a door lift with greater horsepower may be required.

A door for closing a chamber opening (4) in a chamber wall of a vacuum chamber (3) in relation to a surrounding space, in which the vacuum chamber is located, includes a door housing arranged in a surrounding space, a closing member (5) arranged in the surrounding space, and a rod (10), to which the closing member (5) is connected, wherein a first movement of the rod (10), through which the closing member (5) is displaced from an open position into an intermediate position, occurring in the form of a displacement of the rod (10) in the direction of the longitudinal axis thereof, wherein a second movement of the rod (10) subsequent thereto occurs in the form of a displacement of the rod (10) in a direction at an angle to the longitudinal axis thereof and/or in the form of a pivoting of the rod (10) about a pivot axis which is perpendicular to the longitudinal axis thereof, wherein the closing member is displaced from the intermediate position into a closed position via said second movement of the rod. The rod (10) is mounted in a moveable manner via the bearing elements, via the first movement thereof and via the second movement thereof in relation to the door housing, wherein the bearing elements are arranged in an inner space (30) of the door housing, which inner space is sealed with respect to the surrounding space or is connected to the surrounding space via a passage (41) extending through a housing wall (40) of the door housing, in which passage a particle filter is arranged. The rod (10) is guided out of the inner space (30) of the door housing into the surrounding space in a sealed manner.
