The system includes a series of operable louvers mounted on a four-sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver is composing of a four-sided main frame, two panes of glass (inner and outer) and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.

A door closer with a doorjamb mounting plate is a screen door closer or a closer for a similar purposes that has an enlarged door jamb bracket that is attached with at least eight fasteners and has an integrally attached extension that allows for pivotally connecting the extendable arm of a spring loaded or gas tube closer. The closer attaches to the door or the lid and the extension on the enlarged door jamb bracket is optimally designed and angled to reduce stress on the door jamb.

A panel assembly includes a panel mounting frame; a panel cover; and a hinge configured to connect the panel cover to the panel mounting frame. The hinge includes a hinge plate; a first pivot shaft disposed on a first side of the hinge plate and configured to be pivotally connected to the panel mounting frame; and a second pivot shaft disposed on a second side of the hinge plate and configured to be pivotally connected to the panel cover. The panel assembly also includes an elastic element configured to drive the hinge plate to rotate and disposed between the panel mounting frame and the hinge plate. The elastic element is in a compressed state when the panel cover is in a closed state relative to the panel mounting frame.
