Steel Window Replacement

Vinyl Windows used as Replacement Windows were designed to fit into old wood double hung frames with both sash removed. Steel windows were usually installed with screws into the frame around the opening under the sash of operating units or outside the glass of fixed units. Usually covered with putty, most can be located with a little work.
