Difference Between New Construction and Retrofit Impact Windows

How The Frame And Wall Prep Change The Job

What changes most is not the impact rating, but the way the unit integrates with the home.

That one detail drives almost every other difference, from labor time to finish work to how much disruption the homeowner feels.

In Redington Beach FL, the choice often comes down to whether the home is being built, rebuilt, or updated inside an existing wall opening.

What New Construction Impact Windows Are Built For

New construction impact windows are usually chosen when the wall assembly is still open, such as during a new build, a major addition, or a full wall rebuild after severe damage.

When the framing is exposed, crews can correct out-of-square openings, improve flashing details, and set the unit with the wall system in mind from the start.

A poorly flashed new construction unit can underperform a well-installed retrofit window if the work is rushed or the wall details are handled badly.

What Homeowners Should Ask Before Signing

• installation method and anchoring details
• condition of the existing frame or wall opening
• permit and inspection requirements
• frame material, finish, and coastal durability
