Difference Between New Construction and Retrofit Impact Windows

Where New Construction And Retrofit Windows Separate

New construction impact windows are designed to go into an opening that is still being framed, so the installer can work from the studs, set the flashing correctly, and build the wall assembly around the unit.

Retrofit units are built for removal of the old frame and installation into the existing opening, which keeps the drywall, stucco, and interior finishes largely intact.

The practical gap is bigger than it looks on paper because it affects how the unit is anchored, sealed, and finished.

In places like Redington Beach FL, where salt, wind, and storm exposure matter, the installation method is not just a technical detail. It affects long-term performance.

How Code And Structural Conditions Shape The Choice

The Best Choice Depends On The House, Not Just The Catalog
