Impact Windows Built for South Florida Weather, Code and Permits

Impact windows and impact doors are built to resist flying debris and strong wind pressure during a storm. If you’re replacing older openings in South Florida, they’re one of the most direct ways to protect your home before the next storm season. This guide explains how the glass works, how to check a rating, what Florida rules require, and what to expect from ASP Superhome.

What Impact Windows Are and Who They Are For

Impact windows use glass designed to stay in the frame when windborne debris hits it. Standard windows use ordinary glass that can shatter into sharp pieces, leaving an open hole in the wall. Homeowners in storm-exposed areas like Miami, Fort Lauderdale, West Palm Beach, Kendall, Boca Raton, Naples, and Fort Myers often consider impact glass for this reason. Many also want one permanent solution instead of boarding up before every storm. Miami-Dade County’s hurricane window and door guidance covers both approved shutters and plywood boarding, and it notes cost considerations for impact-resistant glass. For a full category overview, read our impact windows guide.

How Impact-Resistant Laminated Glass Works

Impact-resistant laminated glass has two or more glass layers bonded to a tough plastic layer between them. When debris strikes, the glass may crack, but the plastic layer holds the broken pieces together. That helps the opening stay closed during the storm. The glass is only part of the system. The frame, anchoring, and seals must also perform, so installation quality matters as much as the glass itself. The Pacific Northwest National Laboratory’s resource guide on impact-rated glass describes impact-resistant construction and ASTM impact testing in general terms. A product’s rating comes from testing the whole assembly, so the rating must match the exact product you buy.

How to Tell If a Window or Door Is Impact Rated

A properly rated product should come with approval documentation you can check. Florida law says a product may not be advertised, sold, offered, provided, distributed, or marketed as hurricane, windstorm, or impact protection from wind-borne debris from a hurricane or windstorm unless it has the required approval (Fla. Stat. § 553.842). Use this checklist:

• Look for a certification mark or listing from an approved certification agency, which may be used only for products for which the code designates standardized testing. Under Fla. Stat. § 553.8425, a product with that mark needs no further documentation to establish code compliance.
• Check that the documentation names the manufacturer and the model number or identifier. Our team can explain what paperwork your project may need when you request a quote.
• Confirm the rating covers your exact size, frame, and glass setup, not a similar model.
• Ask for the approval documents in writing with your quote, so you can verify them yourself.

What an Impact Window or Door Project Covers

A typical project includes the impact glass units, frames, hardware, anchoring and fastening, sealing, and removal of the old units. ASP Superhome offers impact windows and impact doors. Florida’s statewide product approval system covers exterior doors and windows, and a product may not be advertised as hurricane, windstorm, or impact protection from wind-borne debris from a hurricane or windstorm unless it is approved under s. 553.842 or s. 553.8425 (Fla. Stat. § 553.842). Exact measurements matter because they affect both fit and the rating. Some homeowners with large openings, such as sliding glass doors, also look at permanent accordion shutters. Pinellas County’s retrofitting guidance lists approved storm shutters as one option for large openings like these. Inclusions, exclusions, and warranty terms appear in the written quote, so you can compare each line item.

Florida Building Code, Permits, and County Rules

The Florida Building Code sets construction rules for buildings and for their repair and alteration (Fla. Stat. § 553.73). Installing or replacing exterior impact windows generally requires a permit. Your local building department can tell you which permits your project needs. Window and door projects may require permits, so check with your local building department before work begins. Window replacement requirements can vary by home and location, so ask your local building department about your specific project. Before work starts, confirm which permits apply, which inspections follow, and who handles each step.

What to Expect: From Free Consultation to Installation

The process starts with a free consultation. The first consultation is free, confidential, and carries no obligation to continue. Here is what follows:

1. Free first consultation. We discuss your openings, your goals, and your questions. You can reach us through our contact page.
2. Site measurement. We review each opening, frame condition, and door location.
3. Product selection and written quote. You choose the glass type, frame style, and door options. The quote lists documented product approvals.
4. Permit confirmation and scheduling. Permit and lead-time timelines depend on the facts of each project, so we confirm the schedule in writing.
5. Installation and inspection. We install, seal, and clean up, then complete any required inspection.
