New Construction Window:  New construction windows come with an attached nailing fin along the outer frame that’s used to attach the window to the home before the application of the exterior siding.  New-construction windows typically are of inferior quality as builders continually try to keep costs low, whereas replacement grade windows are of higher quality to replace the original new construction windows.
