Abstract
Abstract A window insulation system adapted for use on large metal or wood framed windows such as used in factories, schools, etc., is installed in spaced relation to a window sash on the side thereof facing the interior of a building. The system includes insulation panels which are mounted on and held in spaced relation to the window by a framework which is supported on brackets mounted on window mullions. Additional stabilization of the system may be provided by brackets which are mounted on window muntins. The framework includes horizontally disposed H-shaped runners with vertical spline members mounted thereon, the spline members having double flanges which are adapted to extend between adjacent edges of the insulation panels. Decorative single-flanged splines cover the space between adjacent panel edges on the building interior side thereof, the single flange extending between the panel edges and the double flanges of the double-flanged spline to removably secure the panels on the framework. J- or U-shaped molding covers the outermost edges of the boards which are adjacent the periphery of the opening in which the panels are mounted.
