Ask anyone who has boarded up a beach house the night before a storm and they will tell you it gets old fast. That is a big reason so many homeowners on Treasure Island, Madeira Beach and the rest of the Pinellas beaches ask us about impact windows and doors.
They are a real investment, so it is fair to ask whether they are worth it. Here is how we walk homeowners through the decision.
Why openings matter in a hurricane
In a strong storm, wind picks up roof tiles, branches, patio furniture and pieces of other buildings. When debris breaks a window or door, wind and rain rush inside. That pressure can push up on the roof from below and lead to much larger damage.
That is why the Florida Building Code has special rules for areas called the wind-borne debris region. The code defines it to include land within one mile of the coastal mean high water line where the ultimate design wind speed is 130 mph or greater, plus any area where the design wind speed is 140 mph or greater. In those areas, glazed openings on new homes need protection from flying debris. Your permit drawings and building department will confirm the requirements for your address.
Your two main choices
Protection can come from impact-rated windows and doors, or from approved shutters or panels that cover regular openings.
| Impact windows and doors | Shutters or panels | |
|---|---|---|
| Storm prep | Lock them and you are protected | Must be put up or closed before each storm |
| Everyday use | Look like regular windows | Stored or rolled up most of the year |
| Noise | Laminated glass can reduce outside noise | No effect when open |
| Security | Laminated glass is hard to break through | Helps only when closed |
| If you are away | Protected all season | Someone has to close them |
| Upfront cost | Usually higher | Often lower, depending on type |
Shutters can be a good fit for some homes, especially on a tight budget. They only work if they are in place, though. For seasonal residents and rental owners on the islands, that is a big deal.
How impact openings show up on your wind mitigation report
Florida insurers use the Uniform Mitigation Verification Inspection Form, OIR-B1-1802, to document features that reduce wind damage. A newer revision of the form took effect for inspections starting April 1, 2026. One of its questions covers opening protection.
The inspector looks at every exterior opening, including windows, entry doors, sliding glass doors, garage doors and skylights. Openings are classified by the type of protection and the testing standard the product meets. The highest class requires every glazed opening to have protection rated for large missile impact. The form then separates whether solid doors and the garage door are also impact rated, only verified for wind pressure, or cannot be verified.
The key point for homeowners: a single unprotected opening can pull the whole house down to a lower rating. Replacing most of your windows and leaving one old slider or garage door can leave money on the table. Our wind mitigation guide explains the rest of the form.
Keep your paperwork. Save the Florida product approval numbers, the permit and the final inspection for every window and door. Wind mitigation inspectors need proof of the rating, and labels on the glass do not always last.
This is general information, not insurance advice. Discounts and credits vary by insurer and policy. Ask your insurance agent how a wind mitigation inspection could affect your premium.
Permits and code rules for replacements
Window and door replacement in Florida needs a building permit. Products must carry a Florida product approval or a local approval for the way they will be installed. The Florida Building Code, Existing Building volume, also has rules for replacement windows and doors in the wind-borne debris region. In general, replacements there need impact-rated glazing or approved opening protection. There are limited exceptions for older homes, and the details vary.
Check with the building department in your city, whether that is Treasure Island, Madeira Beach, St. Pete Beach, Indian Rocks Beach, the Redingtons or St. Petersburg, for the exact requirements. Note that a new edition of the Florida Building Code is expected around the end of 2026, so rules can shift.
Side benefits people notice
- Quieter rooms. Laminated glass can cut down on traffic, wind and beach noise.
- Better security. Laminated impact glass is hard to break through.
- Less storm prep. No hauling panels or wrestling with fasteners.
- UV filtering. Many laminated glass products block much of the sun's UV, which helps protect floors and furniture.
- Peace of mind when you are away. Seasonal and rental owners do not need someone on standby to close shutters.
So, are they worth it?
For many island homes, we think the answer is yes, especially if you are already remodeling, replacing old leaky windows, or planning a new home. The everyday convenience and full-season protection are hard to beat. If you are not ready to do the whole house at once, start with a plan and protect the largest openings first, like sliding glass doors and the garage door.
Pair new openings with a strong roof for the biggest jump in wind resistance. Our guide to the best roof for a beach house covers that side.

Common questions
Do impact windows help on a Florida wind mitigation report?
Yes. Form OIR-B1-1802 has an opening protection question, and the highest class requires every glazed opening to be rated for large missile impact. One unprotected opening can lower the rating.
Do I need a permit to replace windows in Pinellas County?
Yes, window and door replacement requires a building permit, and products need Florida product approval. Your city's building department sets the specific submittal rules.
Are hurricane shutters as good as impact windows?
Approved shutters can protect openings when they are closed. Impact windows protect all season without any setup, and they add noise and security benefits.
