What Replacement Windows Are and Why They Matter

Definition of Replacement Windows

Replacement windows are units installed to upgrade or repair existing openings, often without removing the entire window frame. They can be installed in two main ways: retrofit (pulling in a new sash or unit within the existing frame) and full-frame replacement (removing the entire window, including the frame). Retrofits minimize disruption and cost if the current frame is sound, while full-frame replacements maximize insulation, sealing, and alignment with modern standards when the existing frame is aged or damaged.
