These are replacement windows by JeldWen (seven total).  They are white vinyl, double-hung, double pane, with half screen.  Quite nice when you consider the old wood-sash windows were probably over 50 years old.  Replacement windows are nice because they require no major framing work to install.  Just remove the old sashes along with a couple pieces of trim, install the replacements, insulate, caulk, and replace the trim.  I charge a VERY COMPETITIVE flat rate for replacement window installation.  Give me a holler!  419-212-3200
