Yes, Acadian Windows sells impact-rated windows specifically certified to meet South Alabama hurricane requirements for all designated wind zones.
South Alabama’s proximity to the Gulf of Mexico places most coastal communities in high-velocity hurricane zones that mandate specific window performance standards. Our impact-rated windows undergo rigorous testing protocols that meet or exceed the minimum requirements for the most demanding wind zones in the region.
What “Impact Rated” Means for Hurricane Protection
Impact-rated windows must pass two critical tests established by building codes. The large missile impact test simulates a 9-pound 2×4 lumber piece striking the window at 50 feet per second—the equivalent of debris flying in 130+ mph hurricane winds. The small missile impact test involves shooting ball bearings at the glass to simulate gravel and other small debris carried by extreme winds.
After impact testing, windows must then withstand 9,000 cycles of positive and negative pressure changes that replicate the fluctuating forces during a hurricane. This ensures that even if the outer glass layer cracks, the window assembly remains intact and prevents wind and water intrusion into your home.

Our Impact Window Technology
Our impact-resistant windows combine heavy-duty aluminum frames with laminated glass manufactured using a special silicone glazing process. The glass consists of two panes bonded together with a clear PVB (polyvinyl butyral) laminate layer. This construction is similar to automotive windshield glass that’s designed to remain intact during collisions.
When debris strikes an impact window, the outer glass may crack, but the inner vinyl layer holds all the glass fragments in place. This prevents the window from becoming a gaping hole that allows hurricane-force winds to pressurize your home’s interior—a scenario that often leads to roof failure and catastrophic structural damage.
NOAA’s Hurricane Research Division confirms that protecting window and door openings is among the most important steps homeowners can take to prevent major damage during hurricanes.
Certifications and Approvals
Our impact-resistant hurricane windows use Cardinal’s Sea-Storm® laminated glass, which resists blunt force as well as puncture impacts. This glass passes even the most demanding county building codes’ requirements, and it contributes to compliance with the TAS 201, TAS 203, ASTM E1886, and ASTM E1996 testing protocols as well.
All of our windows are ENERGY STAR certified and AAMA (American Architectural Manufacturers Association) Approved, meaning they not only meet criteria for energy efficiency, but also structural integrity and sealing.
Beyond Hurricane Protection
Impact-rated windows provide benefits beyond storm protection. The laminated glass dramatically reduces outside noise transmission, making your home quieter and more peaceful. This is especially valuable if you live near busy roads, airports, or commercial areas.
The windows also help block harmful UV rays that fade furniture, artwork, carpeting, and hardwood floors. This protection extends the life of your interior furnishings while reducing heat gain that forces your air conditioning system to work harder.
Impact windows serve as a deterrent to break-ins year-round. The laminated glass is extremely difficult to penetrate, discouraging burglars who rely on quickly breaking glass to gain entry. Many homeowners in South Alabama install impact windows as much for home security as for hurricane protection.
Alternatives to Impact Windows
While impact-rated windows provide continuous protection, some homeowners prefer the lower initial cost of standard windows protected by hurricane shutters. Our aluminum hurricane shutters in the Gulf South offer strong wind and debris protection when properly deployed before a storm.
The choice between impact windows and storm shutters often comes down to lifestyle preferences and budget considerations. Impact windows require no action before a storm and maintain your view and natural light year-round. Shutters must be closed before each storm but cost less initially and can be added to existing windows without full replacement.
Professional Installation Matters
Even the highest-rated impact windows will fail if improperly installed. Our certified installation teams follow manufacturer specifications precisely, using the correct fasteners, sealants, and flashing techniques that ensure the window assembly performs as tested and certified.
Improper installation voids product warranties and certifications, leaving your home vulnerable during hurricanes. We document our installations with photos and detailed records that prove code compliance and protect your investment.

Frequently Asked Questions
How long do impact-rated windows typically last in coastal environments?
Impact windows typically last 20-30 years in coastal South Alabama with minimal maintenance. The aluminum frames resist corrosion from salt air, and the laminated glass maintains its integrity far longer than traditional windows.
Can impact windows break during a hurricane?
The outer glass layer may crack upon impact, but the inner laminate layer helps keeps the glass intact and prevents penetration in most circumstances. The window remains sealed and continues protecting your home even after visible damage to the outer surface.
Do I still need hurricane shutters if I have impact windows?
No, impact-rated windows provide complete hurricane protection without storm shutters. However, some homeowners add hurricane shutters for extra security, additional storm protection, or to qualify for higher insurance discounts.
Are impact windows required for all homes in South Alabama?
Not all homes require impact windows, but homes in designated wind-borne debris regions near the coast typically must have either impact-rated windows or approved hurricane shutters. Your local building department can confirm requirements for your specific address.
What’s the price difference between impact windows and regular windows with shutters?
Impact windows typically carry a higher upfront cost, usually around 20-35% more than standard windows. But when you factor in the potential cost of damages to your window, roof, house, and belongings during a hurricane, the cost of impact windows is far less substantial than what you stand to lose due to inadequate hurricane protection.
