TL;DR
A replacement window insert is a complete new window unit sized to fit inside an existing frame after the old sashes and stops come out, leaving the original jambs, exterior trim, and siding untouched. Installation is fast and clean—often under an hour per opening—but each insert gives up roughly an inch of glass in both directions and inherits any rot or squareness problems in the old frame.

Full-frame replacement is the alternative when the existing frame itself has failed.
