If you’ve worked along the Gulf Coast or in Louisiana, you know humidity and weather are constant challenges. For contractors and glazing professionals, choosing the right aluminum door system can make the difference between years of reliable performance and costly replacements. High moisture, salt air, and storms can all impact durability. Fortunately, aluminum remains one of the best materials for storefront and entry systems when designed with humid climates in mind.
Why Aluminum Works in Humid Climates
Unlike steel, aluminum does not rust. This makes it a natural choice for areas where constant moisture is present. However, untreated aluminum can corrode over time, especially when exposed to salt air. That’s why protective finishes matter. Powder coating or anodizing creates a barrier against corrosion while also offering design flexibility. Contractors across Louisiana and the Gulf often recommend dark anodized finishes because they resist spotting and wear in high-traffic environments.
The Role of Thermal Breaks
Hot, humid climates put extra stress on cooling systems in commercial buildings. Aluminum conducts heat, which can increase energy costs if left unchecked. Modern aluminum door systems often include thermal breaks—plastic barriers within the frame that reduce heat transfer. Pairing thermal breaks with insulated or Low-E glass helps keep interiors cooler, which is especially important in places like New Orleans, Baton Rouge, or Houston where summer temperatures soar.
Choosing the Right Hardware
Hardware is just as important as the frame. In humid areas, contractors should select corrosion-resistant materials such as stainless steel or brass for locks, closers, and pivots. High-traffic entries, like retail shops or office buildings, require heavy-duty closers and panic hardware to withstand constant use. A strong frame paired with the right hardware ensures doors stay aligned and operate smoothly even with daily wear.
Glass Options That Perform in the Gulf
Glass selection also plays a key role in door system performance. Laminated glass adds an extra layer of security and storm resistance, making it a smart choice for Gulf Coast projects. Insulated glass units (IGUs) with Low-E coatings help reduce heat transfer and improve energy efficiency. For storefronts in coastal towns, laminated hurricane-rated glass is often the safest choice to meet code and protect against high winds.
Maintenance Considerations
Even the best aluminum systems need some upkeep in humid climates. Contractors should recommend routine inspections for weatherstripping, gaskets, and hardware. Cleaning frames with mild, non-abrasive cleaners prevents salt or mineral buildup, extending the life of the finish. Regular maintenance not only protects the system but also reassures building owners that their investment will last.
Meeting Building Codes in Coastal Areas
Local building codes across Louisiana, Texas, and other Gulf states may require impact-rated systems in hurricane zones. Contractors should confirm these requirements early in the project to avoid delays. Many aluminum door systems are tested for wind and impact resistance, making them compliant with coastal codes when paired with the correct glass.
Conclusion
When it comes to humid climates, aluminum door systems remain a top choice for contractors thanks to their durability, design flexibility, and resistance to corrosion. The key is selecting the right finish, hardware, and glass to meet both performance needs and local codes.
