Exposed edge margins that are formed when a window film is installed on a glazing surface using an aqueous fluid as a lubricant are immediately covered by a series of elongated members that adhere to one or more of the window film or the surrounding frame. The elongated members provide concealed gaps or channels that allow for the slow evaporation of the aqueous fluid as the adhesive on the window film slowly wets and develops maximum bond strength to the glazing surface. The elongated members are preferably left in place as an inner frame. The inner frame device and method can be deployed in attached an light control film to a window, such as UV protective film, IR rejecting film, absorbing film and daylighting film.

Frame systems for sealing window films

An automated ganged louver assembly is adjusted in orientation by an actuator in the louver header that suspends or supports the louver rotation mechanism. The actuator is energized in response to a determination of solar elevation, which is optionally from a light sensor output via a controller. The light sensor employs an optical element to detect at least one of the sun elevation and azimuth, as well as general exterior light levels. The solar elevation and azimuth can also be determined by calculations from the window orientation and latitude. The optical elements and the controller are coupled to at least one of the louvers or the louver header to provide a self contained system that does not require exterior power or controls, unless desired.

Window louver control system

Generally plano rectangular louvers are capable of being ganged in a stacked tiltable array to enhance light re-direction when titled to follow the solar elevation. Combinations of features and optical characteristic avoid optical artifacts and enhance efficiency of light utilization and manufacturing. Different louvers can be combined in alternative ways in such arrays.
