Various systems and methods are provided for controlling access to the insulated glass space of a fenestration unit. A hinge lug is provided including a lug body having a mounting portion, a cam portion defining a curved cam surface, and a retention portion projecting from the cam portion, and a first retention arm extending from the lug body such that the retention arm is elastically deflectable away from the retention lip. A restrictor link is provided including a restrictor link body having a first end and a second end, wherein the restrictor link body is elastically deflectable, a securing lock positioned proximate the second end, and a cap extending from the securing lock, the cap defining an engaging surface operable to engage the lip channel of the sash. A latch system is provided including a latch base with a ramp access aperture and a latch body including a ramp.

A frame system for securing a glazing unit to a window portal includes an elongated primary mount extrusion, an elongated mount stop extrusion, an elongated first gasket, an elongated second gasket and a structural sealant. The primary mount extrusion is secured to the window portal. A mount stop extrusion engages the primary mount extrusion with a pair of ratcheting members. The first gasket and the second gasket define a passage therebetween and the passage has a width so that the glazing unit fits therein. A structural sealant is disposed so as to affix the glazing unit to an inner upper surface of the primary mount extrusion.

A retrofit window kit includes a plurality of magnetic sash elements configured to be positioned at one or more locations on an interior perimeter of the sash and a corresponding plurality of magnetic window grid elements each configured to magnetically couple to one of the magnetic sash elements and constructed as a clip or a cap that fits over and frictionally attaches to an exterior end of a window grid muntin.

A security panel mounting system having: a mounting unit configured to attach to a mounting surface; a securing unit configured to attach to the mounting unit to form a base fixture; a shock gasket configured to nest within the base fixture, wherein the shock gasket is configured to secure a security panel within the base fixture; and a cover configured to engage with the base fixture. A center mullion may be implemented to allow multiple security panels to be mounted within the mounting surface. One advantage is that the security panel mounting system may allow for the utilization of security panels within any window or door to enhance security. Another advantage is that the shock gasket may allow for the expansion and contraction of the security panels, as a result of changes in ambient conditions, to occur without resulting in bowing or deformation of the security panel.

Provided is an internal window system, including: a plurality of sheet members having different functions; and a window frame body for laminating and holding the plurality of sheet members. The plurality of sheet members may have at least 2 different functions among light emission, light dimming, heat shielding, heat insulating, ultraviolet UV shielding, heat generation, solar power generation, electromagnetic wave shielding, visual display function, visual monitor function or visual screen function.

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 press-fit window insert configured to provide secondary protection to an existing window, having a carrier, a fin, and a fastening clip. The carrier includes a substantially rigid framework having channels within the framework configured to securely accept one or more attachments. The fin extends from the carrier and includes a substantially flexible blade extending from a base portion of the fin. The base portion of the fin is configured to interlock the fin to the carrier. The fastening clip includes a substantially rigid brim extending from a base portion of the fastening clip. The base portion of the fastening clip is configured to interlock the fastening clip to the carrier.
