Hurricane Windows vs Impact Windows: Are They the Same?
Short answer: yes — they're the exact same product. "Hurricane windows" and "impact windows" are two names for the same impact-resistant glass. Here's what actually matters when you buy.
The one-sentence answer
Both terms describe windows made with laminated impact-resistant glass and reinforced frames, certified to survive hurricane-force winds and flying debris. The industry calls them "impact windows"; homeowners often say "hurricane windows." Same glass, same certification, same protection.
Side-by-Side (Spoiler: They Match)
| Attribute | "Impact Windows" | "Hurricane Windows" |
|---|---|---|
| Also called | Impact-resistant windows | Hurricane-resistant windows |
| The product | Laminated impact glass + reinforced frame | Laminated impact glass + reinforced frame |
| Glass | PVB/SGP interlayer (holds together) | PVB/SGP interlayer (holds together) |
| Certification | Miami-Dade NOA / FL Approval | Miami-Dade NOA / FL Approval |
| HVHZ code | Compliant | Compliant |
| Insurance discount | 30-45% windstorm | 30-45% windstorm |
| Difference | — none — | — none — |
What to Look for Instead of the Name
Stop comparing "hurricane" vs "impact" — they're identical. These are the three specs that actually determine protection and code compliance in South Florida:
Notice of Acceptance — the certification required for the HVHZ (Miami-Dade & Broward). Florida Product Approval alone isn't enough here.
How much wind load the window withstands. +/-50 PSF meets code for most homes; coastal/high-rise needs more (ESW starts at +/-80).
Large-missile rating (9-lb 2x4 at 50 ft/sec) is required for most South Florida residential openings.
Why Are There Two Names?
"Impact-resistant window" is the technical term used in the Florida Building Code, manufacturer spec sheets, and NOA documents. "Hurricane window" is the marketing and everyday term — it describes what the product protects against. Some companies use "hurricane windows" in ads because that's what homeowners search for. There is no certification, glass type, or performance difference between a window labeled "hurricane" and one labeled "impact."
The only related term that is different is hurricane window film — a stick-on film that is not the same as impact glass and does not meet Florida code on its own.
Frequently Asked Questions
Are hurricane windows and impact windows the same thing?
Yes. 'Hurricane windows' and 'impact windows' are two names for the exact same product: windows built with laminated impact-resistant glass and reinforced frames that withstand hurricane-force winds and flying debris. The industry term is 'impact windows' (or 'impact-resistant windows'); 'hurricane windows' is the common consumer term. There is no difference in the product, certification, or protection.
What is the difference between hurricane windows and regular windows?
Regular windows shatter on impact. Hurricane/impact windows use a laminated glass with a PVB or SGP interlayer that holds together when struck — like a car windshield — so the opening stays sealed even if the glass cracks. They also have heavier frames anchored to the structure. This protects your home from the pressure changes and debris that cause most hurricane damage.
Do I need hurricane windows or impact windows in Florida?
They're the same thing, and in South Florida's High-Velocity Hurricane Zone (Miami-Dade and Broward), any new or replacement window must be impact-rated with a Miami-Dade NOA — OR the opening must be protected by approved shutters. Impact windows satisfy the code permanently with no operation needed during a storm, which is why most homeowners choose them.
Are hurricane impact windows worth the cost?
Yes — for most South Florida homeowners they pay for themselves in 4-8 years through 30-45% windstorm insurance discounts ($1,500-$3,500/year), plus energy savings and higher home value. Buying in-stock through Windows Stock Market cuts the upfront cost 30-60% versus custom orders.
What should I actually look for instead of the name?
Ignore 'hurricane' vs 'impact' marketing and check three things: (1) a valid Miami-Dade NOA or Florida Product Approval, (2) the design pressure rating (PSF) for your home's exposure, and (3) the missile impact level (large-missile for most South Florida homes). All windows on Windows Stock Market meet these for HVHZ installation.
How much do hurricane impact windows cost in South Florida?
Installed in 2026, expect roughly $400-$650 per window for Mr. Glass, $500-$800 for ESW, and $650-$1,100 for PGT. A typical 10-window home runs $8,000-$22,000 installed with in-stock inventory versus $18,000-$28,000+ through a custom showroom.
