Hurricane season in Florida and other parts of the United States is not just a seasonal concern; it is a constant reality that demands high-performance architectural solutions. For architects, contractors, and property owners committed to safety, efficiency, and regulatory compliance, choosing certified aluminum and glass doors and windows is essential.

1. Beyond aesthetics: Functionality and safety against Hurricanes 🚧

Modern aluminum and glass systems offer more than just sleek design; they provide a solid defense against extreme weather conditions. Aluminum is known for its durability and corrosion resistance, while laminated glass serves as a reliable barrier against impact.

These solutions are engineered to withstand high-speed winds and flying debris typically encountered during hurricanes, protecting both the building’s structural integrity and its occupants. The aluminum and glass combination not only aligns with contemporary architectural trends but also enhances safety during extreme weather events.

2. Regulatory compliance and certifications

(⚠️ Non-negotiable in Florida)

In Florida, particularly in areas like Miami-Dade County, building codes are strict due to high hurricane exposure. Windows and doors must meet certifications such as the Miami-Dade Notice of Acceptance (NOA), which are essential for validating their resistance.

At UNI-K Fenestration, we don’t just meet these standards — we exceed them. All our products are tested in accredited laboratories and certified by the relevant agencies, delivering high-performance solutions.

🔒 LMI and SMI Certifications: Why Are They Critical?

LMI (Large Missile Impact) and SMI (Small Missile Impact) certifications are fundamental for projects in high-risk areas like South Florida.

Large Missile Impact, evaluates the system’s ability to withstand impacts from large objects such as wood planks or roof tiles during a hurricane. Certified products must also endure cycles of positive and negative pressure that simulate wind forces post-impact.

Small Missile Impact, measures resistance to small, high-speed debris like stones, branches, or metal fragments.

Choosing systems with these hurricane certifications not only protects occupants but also ensures legal compliance and structural longevity.

For architects and builders working in HVHZ (High Velocity Hurricane Zone) areas, UNI-K Fenestration solutions offer a secure, modern, and dependable alternative.

3. Additional benefits: Energy efficiency and added value 🏡

In addition to hurricane resistance, our systems provide:

🌡️ Energy Efficiency: With Low-E glass and thermally broken aluminum profiles, they help maintain indoor temperatures, reduce air conditioning use, and lower energy bills, potentially even leading to insurance benefits.

🎧 Noise Reduction: Laminated glass also acts as an acoustic insulator, making it ideal for dense urban areas or locations near airports.

💰 Increased Property Value: Installing hurricane-certified doors and windows adds value through enhanced safety and improved energy efficiency.

4. Technical considerations for professionals 🛠️

If you're an architect or contractor, keep in mind:

🌬️ Wind Load: It’s essential to calculate appropriate design pressure based on the building’s location and height.

🪟 Glass Selection: Laminated glass with various configurations offers improved impact performance.

🔧 Frame Design: Aluminum frames should include internal reinforcements and efficient drainage to prevent water infiltration.

Investing in SMI (Small Missile Impact) or LMI (Large Missile Impact) certified aluminum doors and windows is not just about protecting a structure; it is about building with long-term vision. In states like Florida, where hurricanes are a constant threat, making responsible architectural decisions is not just advisable; it is essential.
