According to the National Oceanic and Atmospheric Administration (NOAA), an average Atlantic hurricane season has 14 named storms, seven hurricanes, and three major hurricanes. This means that homes and businesses alike in the affected areas must be designed to withstand inclement weather. Otherwise, both people and properties face hazards and safety risks, which can be damaging and costly.
When designing a property, architects must specify hurricane windows that will withstand harsh weather. This is how you can do so in 2026.
Understand Wind Maps and Site Exposure Requirements
First, you must have a clear understanding of regional wind maps and site exposure classifications. Consult with the latest building codes (e.g., ASCE 7) to determine the basic wind speed for the specific project location. Then, identify whether the structure falls within Exposure B, C, or D.
Usually, coastal properties will face higher wind loads since there’s unobstructed terrain. Therefore, this will influence the performance requirements needed of the hurricane windows. You should also consider:
- Topography
- Building height
- Surrounding structures
After understanding the local area better, you can make climate-specific product choices that fit both safety standards and code compliance. Not only that, but you can also have smoother replacement workflows and select the best window repair in Jacksonville possible in the future.
Address Energy Codes, Submittals, and Field Quality Assurance
The hurricane windows you select should also fit with energy efficiency requirements. You can ensure compliance with the current energy codes by picking windows with appropriate:
- U-values
- Solar heat gain coefficients (SHGC)
- Air leakage ratings
In addition, you need a thorough submittal and field quality assurance (QA) process. These checklists should include:
- Product approvals
- Test reports
- Shop drawings
- Installation instructions
During construction, have field QA to verify proper installation, anchoring, and sealing.
Afterward, make sure to have regular inspections. These can help ensure that the hurricane windows are performing as intended.
Calculate Design Pressures for Accurate Window Performance
After you’ve gathered wind data, the next step is design pressure (DP) calculations. This helps you determine the forces that the hurricane windows must withstand. These calculations factor in:
- Wind speed
- Building height
- Zone location on the structure
- Internal pressure conditions
Keep in mind that both positive and negative pressures should be evaluated since the windows have to resist inward and outward forces during a storm.
With the right DP rating, you can have peace of mind knowing that the selected window assemblies can maintain structural integrity, even under extreme conditions. To improve accuracy, consider collaborating with structural engineers or using certified calculation tools.
It can be beneficial to have clear documentation of your calculations. They can help guide manufacturers in producing compliant and project-specific window systems.
Specify Impact Resistance Standards
It’s imperative that hurricane windows meet impact resistance standards, as they must protect against flying debris. You should specify compliance with ASTM standards, such as ASTM E1886 and ASTM E1996. There are also regional protocols, such as Florida-specific TAS 201, 202, and 203.
All of the above evaluate a window’s ability to withstand both large missile impacts and cyclic wind pressures. If you choose products that are tested and certified to these strict benchmarks, then you’ll ensure that the glazing and framing systems stay intact during hurricanes.
Don’t forget to verify:
- Labeling
- Certification documentation
- Approved product lists
Doing so will enhance safety, as well as streamline permitting and inspection processes.
Choose Durable Frame Materials and Plan for Water Management
It’s obvious that the materials you select play an essential role in long-term window performance, but this is especially true in coastal environments. The salt air and humidity can quickly degrade inferior materials and compromise window performance over time, so you should prioritize frame materials that resist corrosion, such as:
- Vinyl
- Fiberglass
- Properly treated aluminum with protective coatings
Also, there must be proper water management integrated into the window design. To prevent water intrusion during wind-driven rain events, architects should specify effective:
- Flashing systems
- Sealants
- Drainage paths
If you want to further enhance performance, consider detailing sill pans and weep systems. The ultimate goal is to not only resist storm damage but also to prevent moisture-related issues, such as mold and structural deterioration.
Pick the Right Hurricane Windows for Each Project
The right hurricane windows are needed for each property, or else you face costly failures. Not only that, but you risk your reputation as an architect, too.
Luckily, you can avoid these negative experiences by carefully specifying hurricane windows. By understanding wind maps, addressing energy codes and field QA, calculating DP, and specifying impact resistance standards, you’ll be better able to choose the right frame materials and plan for water management. As a result, you’ll successfully tailor your projects to your clients’ needs.
