Yes, all windows installed by Acadian Windows meet or exceed current City of Mobile and Mobile County building codes for wind-borne debris protection.
Mobile and Baldwin County fall within specific wind zones that require windows to meet stringent impact resistance standards. Alabama’s coastal building codes mandate protection against wind-borne debris for all new construction and replacement window projects in designated hurricane zones.
Understanding Wind Zone Requirements for Mobile Area
The City of Mobile and surrounding coastal communities are located in Wind Zone 2, which requires a higher level of wind resistance for building components. This designation means windows must withstand sustained wind speeds of up to 100 mph, along with the impact of airborne debris generated during hurricane-force winds.
Building codes in these areas specifically reference the International Residential Code (IRC) and International Building Code (IBC), which set minimum standards for window performance. FEMA guidelines emphasize that protecting wall openings like windows is one of the most critical factors in preventing catastrophic home damage during hurricanes.
| Wind Zone | Areas Affected | Required Wind Speed Rating |
|---|---|---|
| Zone III | None | Up to 110 mph |
| Zone II | Baldwin and Mobile counties | Up to 100 mph |
| Zone I | Autauga, Barbour, Bibb, Blount, Bullock, Butler, Calhoun, Chambers, Cherokee, Chilton, Choctaw, Clarke, Clay, Cleburne, Coffee, Colbert, Conecuh, Coosa, Covington, Crenshaw, Cullman, Dale, Dallas, DeKalb, Elmore, Escambia, Etowah, Fayette, Franklin, Geneva, Greene, Hale, Henry, Houston, Jackson, Jefferson, Lamar, Lauderdale, Lawrence, Lee, Limestone, Lowndes, Macon, Madison, Marengo, Marion, Marshall, Monroe, Montgomery, Morgan, Perry, Pickens, Pike, Randolph, Russell, St. Clair, Shelby, Sumter, Talladega, Tallapoosa, Tuscaloosa, Walker, Washington, Wilcox, and Winston counties | Up to 70 mph |
Impact-Resistant Windows for Code Compliance
Our impact-resistant hurricane windows combine heavy-duty aluminum frames with specially engineered glass. The glass undergoes a special silicone glazing process that keeps it from shattering upon impact. While the outer layer may crack when struck by debris, the inner layer works to keep the glass intact, helping prevent wind and rain from entering your home. These windows have been tested and certified to meet the most stringent coastal building code requirements in the country.
Hurricane Shutters as an Alternative Compliance Method
Mobile and Mobile County building codes also allow hurricane shutters as an approved method of wind-borne debris protection. Our aluminum hurricane shutters are powder-coated and available in colonial, Bahama, and board and batten styles. Each style meets local code requirements when properly installed.
Shutters offer the advantage of protecting standard windows while providing the same level of code compliance as impact-resistant glass. Many homeowners choose this option for its cost-effectiveness and the added security benefits shutters provide year-round.
Design Pressure Ratings Explained
Beyond impact resistance, windows must meet specific design pressure (DP) ratings that indicate their ability to withstand wind pressure without failing. Mobile County typically requires DP ratings between 30 and 50, depending on the home’s distance from the coastline and its height.
Every window we install carries documentation showing its DP rating and impact resistance certification. This documentation is required when pulling building permits and ensures your windows meet all applicable codes.
Our Compliance Process
When you choose Acadian Windows for your Mobile window installation project, we handle all aspects of code compliance. Our team stays current with any changes to local building codes and ensures every product we install meets or exceeds current requirements.
We work directly with local building departments to verify specifications and obtain proper approvals. Our installers follow manufacturer specifications precisely, as improper installation can void certifications even when code-compliant products are used.
Visit our Mobile showroom at 920 Lakeside Dr, Unit A, Mobile, AL 36693 to review product certifications and discuss which code-compliant options work best for your home’s specific location and wind zone designation.
Frequently Asked Questions
Do I need impact windows if my home is not directly on the beach?
It depends on your exact location. Homes within one mile of the coast in Mobile County typically require either impact-resistant windows or approved hurricane shutters. Inland properties may have different requirements based on their specific wind zone.
Will impact windows protect my home better than HURRICANE shutters?
Both options provide strong protection when properly installed and maintained. Impact windows offer the advantage of continuous protection without deployment, while hurricane shutters must be closed before a storm but cost less initially.
How do I know what wind zone my Mobile home is in?
The City of Mobile Building Department can provide wind zone information for your specific address. Baldwin and Mobile counties are the only counties in Alabama in Wind Zone 2. All other counties are designated Wind Zone 1.
Do replacement windows need to meet the same codes as new construction?
Yes, replacement windows in Mobile County must meet current building codes for wind-borne debris protection, even if your existing windows were grandfathered under older standards.
Can I install regular windows with shutters to meet code?
Yes, standard windows paired with code-compliant hurricane shutters satisfy Mobile County building code requirements for wind-borne debris protection.
