Living in Punta Gorda or anywhere in Charlotte County, FL, means being prepared for hurricane season year after year. Your hurricane impact windows are one of the most important defenses against Florida’s severe weather—but how can you tell if they actually meet current Florida Building Code (FBC) standards?
Whether your home is in Punta Gorda, Port Charlotte, or anywhere across Southwest Florida, here’s how to make sure your windows are code-compliant and built to protect your home.
1. Check for the Florida Product Approval Number
Every hurricane-rated window installed in Florida should have a Florida Product Approval (FPA) number. This number confirms the product has passed rigorous testing for impact resistance, air pressure, and water infiltration according to state standards.
You can usually find this number:
-
On a small label etched into the glass or inside the window frame.
-
On documentation from your installer or manufacturer.
To verify, search the Florida Product Approval database. If your windows don’t appear there—or lack an approval label—they may not meet the latest Florida Building Code for impact windows.
2. Look for a Miami-Dade or Broward County Notice of Acceptance (NOA)
In South Florida’s High-Velocity Hurricane Zone, all impact-rated products must carry a Notice of Acceptance (NOA) from Miami-Dade or Broward County. These are among the most stringent certifications in the nation.
Even though Punta Gorda and Charlotte County aren’t within that zone, using windows with a Miami-Dade NOA is a smart investment. They typically exceed standard code requirements, giving you added protection and long-term peace of mind.
3. Confirm Wind Zone and Design Pressure (DP) Ratings
Florida’s wind-borne debris regions each require different levels of strength. The Design Pressure (DP) rating indicates how much wind force your window can withstand.
For Charlotte County homes and other coastal areas in Southwest Florida, you’ll generally want:
-
DP ratings of +50/-50 or higher, depending on your home’s exposure and elevation.
-
Large-missile impact resistance, tested with a 9-pound 2×4 traveling at 34 mph.
These ratings are often printed on your window’s certification label or paperwork. If you’re unsure what your property requires, a licensed contractor can confirm your zone and the correct specifications.
4. Review the Installation Date and Building Permits
The Florida Building Code has evolved significantly, especially after major storms like Hurricane Charley (2004) and Hurricane Ian (2022). If your hurricane impact windows were installed before 2010, they might not meet current standards.
Check your local building department’s permit records or contact your installer for documentation. Properly permitted windows in Charlotte County, FL indicate that they were approved under the building code in effect at the time of installation.
5. Inspect for Damage or Deterioration
Even if your windows were compliant when installed, wear and tear can compromise their effectiveness. Look for:
-
Cracks or delamination in the glass.
-
Corrosion or discoloration on frames.
-
Loose seals or gaps around the window edges.
Any of these issues can reduce your window’s ability to withstand hurricane conditions. If you notice signs of damage, it’s time for a professional evaluation.
6. Schedule a Professional Window Inspection in Punta Gorda
The best way to confirm compliance is through a professional inspection by a licensed contractor experienced in hurricane windows. They can verify your window’s certifications, test the frame and anchoring system, and determine whether replacements are needed.
