IMPACT RESISTANT WINDOW

A novel impact and blast resistant window is presented. A surface of a window pane that is adjacent to an interior of a building has a durable transparent polymer film coated or adhered thereto. The surface of a window pane that is adjacent to an interior of a building is sealed to the sash by double sided tape. The resulting window produces an unexpected ability for the durable transparent polymer film to retain pieces of broken glass driven toward the interior of the building by a missile striking an exterior of the window, without the durable transparent polymer film pulling loose from the window sash.
