Abstract: A window screen attachment apparatus and method for attaching a screen to a window frame. The apparatus includes a mesh screen with a rigid frame, a number of ferromagnetic cups and mating permanent magnets, and a gasket. Each cup is permanently attached to the screen frame at the surface or in a recess, and includes a depression with a flat floor and a perpendicular wall. The magnet is shaped to fit relatively snuggly into the depression. The cup is either a single piece of ferromagnetic material, separate floor and wall components, or a single floor component and a wall that is the sides of a recess in the screen frame. The magnets are attached to the window frame by an adhesive that is initially protected by a release layer. The gasket is a set of compressible strips that provides a barrier items passing through the gap between the window and screen frames. The window screen is attached by placing the magnets in the cups, removing the release layer, and pressing the adhesive against the window frame.
