In South Florida, protecting your home from the devastating impact of hurricanes isn’t just a luxury—it’s a necessity. Between June and November, the Atlantic hurricane season poses a real threat to homes across the region. That’s why so many homeowners are turning to Impact windows and South Florida impact doors to safeguard their property. But here’s the catch—not all windows labeled as impact-resistant are truly hurricane-rated.
So how can you tell if your windows are the real deal? Whether you're considering a Miami Lakes window replacement or simply want to verify the protection your current windows offer, understanding what makes a window truly hurricane-rated is critical. In this blog post, we'll walk you through everything you need to know, so you can protect your home with confidence.
What Does Hurricane-Rated Actually Mean?
A hurricane-rated window is specifically designed and tested to withstand the extreme conditions produced by a hurricane—high-speed winds, air pressure changes, and flying debris. These windows must meet specific standards set by governing bodies, particularly in places like Miami-Dade County, which has some of the strictest building codes in the nation.
A hurricane-rated window typically includes:
Laminated impact-resistant glass (two glass panes bonded with an inner plastic layer)
Reinforced frames made from aluminum, vinyl, or fiberglass
Advanced locking mechanisms to prevent failure under pressure
Seals and anchoring systems designed to hold firm during intense storms
Why Proper Certification Matters
You may come across many products marketed as storm-proof or impact-resistant, but that doesn't guarantee they're Miami-Dade County approved or meet HVHZ (High-Velocity Hurricane Zone) standards. Products that aren’t properly tested and certified may fail during a storm, putting your home and family at risk.
That’s why working with a trusted provider like Prestige Windows & Doors is essential. We only install certified Impact windows and South Florida impact doors that meet or exceed all local and state regulations.
How to Tell If Your Windows Are Truly Hurricane-Rated
Let’s break down the specific ways you can confirm whether your windows are genuinely hurricane-rated:
1. Look for a Permanent Mark or Label
All certified impact windows should have a permanent mark or etched label on the glass. This label often includes:
The manufacturer's name
Certification numbers
The glass type (e.g., laminated, tempered)
Compliance codes (e.g., Miami-Dade County or ASTM)
Tip: Check the corners of the windowpane for a small, etched logo or writing—it may be hard to spot but should be visible upon close inspection.
2. Check for Product Approvals
The State of Florida maintains a searchable online database of approved building products, including impact windows. You can search for your specific window brand and model at the Florida Product Approval website or check the Miami-Dade NOA (Notice of Acceptance) database.
Steps to Verify:
Find the manufacturer and model number on the window label.
Search the product approval number on the Florida Building Code website.
Ensure the window is rated for use in a High-Velocity Hurricane Zone (HVHZ).
Prestige Windows & Doors always provides documentation of certification for every product we install, ensuring you're fully compliant and protected.
3. Examine the Glass Composition
True Impact windows use laminated glass, often referred to as safety glass. Laminated glass consists of two panes bonded together with a durable plastic interlayer. In the event of impact, the outer pane may crack, but the interlayer holds the pieces in place.
To tell if your windows have laminated glass:
Tap the glass—laminated glass often sounds slightly duller than standard glass.
Visually inspect the edge of the glass for the laminated layer.
Ask the installer or builder to confirm the glass composition.
If you're unsure, it's best to contact an expert like Prestige Windows & Doors for a free inspection.
4. Evaluate the Window Frame
The frame is just as important as the glass when it comes to impact resistance. Hurricane-rated windows feature reinforced frames that are tightly sealed and anchored to your home’s structure.
Materials to look for:
Aluminum: Very strong and commonly used in large window openings.
Vinyl: Excellent for insulation and corrosion resistance.
Fiberglass: Highly durable and thermally efficient.
Flimsy or corroded frames may indicate that your window is not up to hurricane standards, even if the glass is laminated.
5. Ask for Documentation
If your windows were installed by a builder or previous homeowner, and you're unsure of their quality, ask for:
Product specification sheets
Warranty information
Building permits from the installation
Inspection reports from past renovations
Companies like Prestige Windows & Doors always provide detailed documentation for all Miami Lakes window replacement projects, including product specs, certifications, and warranty coverage.
The Risks of Uncertified Windows
If your windows aren’t truly hurricane-rated, you’re not just risking physical damage—you may also face:
Higher insurance premiums
Code violations during home inspections
Potential denial of claims after a storm
Lower property value
Don't wait for a hurricane warning to find out your windows aren’t compliant. A proper inspection and upgrade can save you thousands in repairs and insurance costs.
