ABSTRACT:
A lightweight removable combination air and insect control panel for mounting on the internal or external sides of window frames in situ for the tight sealing thereof, said panel having two portions, a full frame portion having a sheet of rigid transparent material in its upper second and a sheet of screen material in its lower section, both being tightly secured in a lightweight frame structure. A second half-frame portion has a sheet of rigid transparent material secured in a similar half-size perimeter frame sized to fit over the screened section of the full frame portion. The frame structure also includes grooves for the insertion and securing of flexible weather stripping to ensure a tight retention of the screen material and a tight seal against the window frame. Two circular loops at the top of the panel engage corresponding hooks on the window frame. A minimal number of side and base spring loaded fastening means are used to secure the combination control panel in its sealed position. Using only the full frame portion, the combination control panel functions as a window screen. Hanging the half-frame portion over the screened section converts it to a full storm sash or air control panel.
