<p>The window frame has a flat casing around three edges. A flat sheet of glass is applied over the window frame as a storm sash. Flat ferromagnetic strips are secured along the face of the casing adjacent the three edges. A mounting member extends along the edges of the sheet and is made up of outer and inner portions connected by a hollow, resilient intermediate portion. The outer portion has a flat face for engaging the strip and the inner portion has opposed resilient edges, at least one of which are grooved to receive the sheet. When the sheet is applied flat to the frame, the face of the mounting engages the strips and an edge of the member engages the bottom of the window frame, for sealing. Permanently magnetic material in the mounting member is adjacent the flat face for magnetically and resiliently holding the sheet to the frame.</p> |
