Hurricane Windows vs Impact Windows: What's the Difference?
Many Melbourne FL homeowners ask: "What's the difference between hurricane windows and impact windows?" The short answer: they're the same thing. But there's more to understand about terminology, Florida building codes, and making the right choice for your Brevard County home.
Key Takeaways
- ✓"Hurricane windows" and "impact windows" are two names for the same product
- ✓All must meet Florida Building Code requirements for wind resistance
- ✓Melbourne homes require impact-rated windows per Brevard County codes
- ✓Both terms refer to laminated glass designed to withstand debris impact
Understanding the Terminology
What Are Impact Windows?
Impact windows, also called impact-resistant windows, are specially engineered windows featuring laminated glass with a strong interlayer (typically polyvinyl butyral or PVB). This construction allows the window to absorb impacts from flying debris without shattering, maintaining the building envelope's integrity during hurricanes.
What Are Hurricane Windows?
Hurricane windows are windows designed to withstand hurricane-force winds and flying debris. They use the exact same laminated glass technology as impact windows. The terms are interchangeable - manufacturers and contractors use both names to describe the identical product.
Industry Terminology
In the window industry, you'll hear various terms: impact windows, hurricane windows, impact-resistant windows, storm windows, and wind-resistant windows. In Florida, these all typically refer to the same product: windows that meet Florida Building Code requirements for wind-borne debris regions.

Florida Building Code Requirements
What Does Florida Law Require?
Florida Building Code (FBC) divides the state into wind zones. Melbourne and Brevard County fall under the Wind-Borne Debris Region, which requires all new construction and window replacements to meet specific impact resistance standards.
Brevard County Requirements:
- Design Pressure: Minimum DP40-DP50 rating required
- Impact Testing: Must pass ASTM E1886 and E1996 standards
- Product Approval: Florida Product Approval number required
- Installation: Must be performed by licensed, insured contractors
- Permits: Building permits and inspections mandatory
Testing Standards Explained
All impact/hurricane windows sold in Florida must pass rigorous testing:
Large Missile Impact Test
A 9-pound 2x4 lumber projectile is fired at the window at 50 feet per second (equivalent to 175+ mph winds). The window must remain intact without penetration.
Cyclic Pressure Testing
After impact, windows undergo 9,000 pressure cycles simulating hurricane wind loads to ensure they maintain structural integrity throughout the storm.
Types of Impact/Hurricane Windows
While the base technology is the same, impact windows come in different configurations:
1. Standard Impact Windows
Basic laminated glass meeting minimum Florida Building Code requirements. Good for budget-conscious homeowners.
2. High-Performance Impact Windows
Enhanced laminated glass with Low-E coating, argon gas fill, and superior frames. Better energy efficiency and noise reduction.
3. Miami-Dade NOA Certified Windows
Highest level of impact protection. Tested to most stringent standards. While not required in Brevard County, these provide maximum protection and best insurance discounts.
When to Choose Each Option
Choose Impact/Hurricane Windows If:
- ✓You live in Brevard County or any coastal Florida area
- ✓You're building a new home or doing major renovations
- ✓You want maximum hurricane protection and peace of mind
- ✓You want to maximize insurance discounts (20-40% savings)
- ✓You value noise reduction and energy efficiency
- ✓You want year-round protection without shutters
- ✓You're concerned about home security
Avoid Standard Windows If:
- ✗You live anywhere in Florida (not code-compliant)
- ✗You're replacing windows on a coastal property
- ✗You want insurance discounts
- ✗You need building permits (won't be approved)
- ✗You value your home and family's safety
- ✗You want to maintain property value
- ✗You care about long-term cost savings

HVHZ vs Non-HVHZ: What Melbourne Homeowners Need to Know
Florida's building codes divide coastal areas into two protection zones, and understanding which zone your home falls in directly affects which impact windows you need and what you'll pay:
HVHZ (High-Velocity Hurricane Zone)
The strictest standard in Florida. Originally only applied to Miami-Dade and Broward counties, but coastal Brevard County properties within 1 mile of the ocean must also meet enhanced standards.
- •Large missile impact test (9 lb 2x4 at 50 fps)
- •Must carry Miami-Dade NOA (Notice of Acceptance)
- •Design pressure DP50+ required
- •Applies to: Cocoa Beach, Cape Canaveral, Satellite Beach, Indian Harbour Beach, beachside Melbourne
Wind-Borne Debris Region (Non-HVHZ)
Still requires impact protection, but with slightly less stringent testing standards. Covers most mainland Brevard County properties.
- •Florida Product Approval (FPA) required
- •ASTM E1886/E1996 testing standards
- •Design pressure DP40+ typically sufficient
- •Applies to: Melbourne, Palm Bay, Viera, Rockledge, West Melbourne, Titusville
Our Recommendation for Brevard County
Even if your property isn't technically in the HVHZ, we recommend installing Miami-Dade approved impact windows whenever possible. The cost difference is typically 10-15% more, but you get the highest level of protection and the best insurance discounts. Many insurance companies give larger premium reductions for Miami-Dade certified products regardless of your zone.

Common Questions
Can I use regular windows with hurricane shutters instead?
While shutters provide protection, they must be installed before each storm, stored when not in use, block natural light, and don't provide year-round benefits like energy efficiency, noise reduction, or security. Impact windows are "install and forget" protection.
Do impact windows need shutters?
No. Impact windows provide complete hurricane protection without shutters. This is one of their primary advantages - continuous protection with unobstructed views and natural light.
Are impact windows required in Melbourne FL?
Yes. Melbourne is in a wind-borne debris region. All new construction and window replacements must use impact-rated windows or have approved shutters. Impact windows are the preferred modern solution.
How long do impact windows last?
Quality impact windows last 20-30+ years with minimal maintenance. The laminated glass doesn't degrade like shutters or other temporary protection systems.
Do impact windows reduce noise from outside?
Yes, significantly. Impact windows reduce outside noise by up to 50 decibels thanks to the laminated glass construction. Homeowners near airports (Melbourne Orlando International), highways (I-95, US-1), or busy streets notice an immediate difference. Many Melbourne homeowners cite noise reduction as an unexpected benefit they didn't anticipate when purchasing for hurricane protection.
Can impact windows be broken into?
Impact windows are extremely difficult to breach. The laminated glass construction that resists hurricane debris also resists break-in attempts. Even if the outer glass layer cracks, the PVB interlayer holds the glass together, preventing entry. Police departments across Florida report that homes with impact windows experience significantly fewer break-ins.
What's the difference between aluminum and vinyl impact window frames?
Aluminum frames are stronger and thinner (better views) but conduct more heat. Vinyl frames offer better insulation and are lower maintenance but are slightly bulkier. For coastal Brevard County homes, we often recommend aluminum for ocean-facing windows (strength) and vinyl for inland-facing windows (efficiency). Read our aluminum vs vinyl comparison for details.
Buying Impact/Hurricane Windows in Melbourne FL: What to Know
As Melbourne's trusted impact window installer, here's our practical advice for Brevard County homeowners ready to purchase:
Choose the Right Brand for Your Location
Cocoa Beach, Satellite Beach, Cape Canaveral (barrier island): PGT or ES Windows with Miami-Dade NOA certification. These oceanfront areas need the highest protection and qualify for the best insurance discounts with NOA-certified products.
Melbourne, Palm Bay, West Melbourne (mainland): ES Windows offers the best value for most family homes. Miami-Dade NOA available but not required — still recommended for better insurance discounts.
Viera, Rockledge (inland): Any brand works. Consider vinyl frames for maximum energy efficiency. ECO is a great budget option for inland properties with less salt exposure.
Apply for the MSFH Grant Before Buying
The My Safe Florida Home program provides up to $10,000 in matching grants. The state pays $2 for every $1 you spend. Apply BEFORE you start your project — doing work before grant approval disqualifies you. We're an approved MSFH contractor and help with the entire application process. Read our complete MSFH guide.
Install Before Hurricane Season
Hurricane season runs June 1 - November 30. The best time to install is January through May when lead times are shortest (2-6 weeks vs 8-12 during season), contractors are most available, and you're protected before any storms form. Melbourne averages a significant hurricane impact every 3-4 years — don't gamble with your home.
