Home Window Replacement — What is That?

Home window replacement refers to new windows that mount within the frame of an existing home window. They are typically made without a structural frame; instead, they rely on the strength of the original window for support.

Replacement home windows are different from new-construction windows because new-construction windows have a "fin" along the outer frame. This fin provides a surface so that the window can be nailed in from the outside of the home before siding is installed.

Because windows manufacturers make replacement home windows without this "fin," they can be installed with minimal interference with the existing trim and siding.

New replacement windows can greatly decrease energy loss and outside noise, compared to a single-pane window. Most replacement windows carry the "E-Star" rating for home efficiency.

When windows have become deteriorated, drafty, non-functional, or simply unfashionable, home window replacements are an inexpensive and long-lasting solution for homeowners.
