<p>This motorized, fully automated device remedies the obvious security and thermal deficiencies of glass windows in buildings generally. These R-25 insulated panels (minimum) are designed to close snuggly with their insulated frame -- which is thermally bonded to the building around the respective window in retrofits, and is built-in to new construction projects -- thus optimizing building thermal efficiency, while enhancing security impenetrability. Acting as an awning in the raised position, the panels shield direct sunlight into the window. Both models, for large windows (Fig.3) or for small windows (Fig. 10), close and open on demand by electric switch; or open manually by crank, in no-power mode; they are also fully automated, cycling according to pre-programming -- usually from dusk to dawn, or when building unoccupied. Specialty models will accommodate more intense requirements such as in the far north, hurricane zones, or inordinate crime-risk areas for example.</p> |
