Up to Code: Hurricane Windows and More

As we begin yet another hurricane season here on the Gulf Coast, we thought it appropriate to look into some of the steps that custom builders take to protect your house and family. When you build a new custom home in Florida (or decide to renovate your older home), you will be required to ensure that your windows are up to code. After Hurricane Andrew in 1992, the state implemented sweeping code changes to better protect residents and their homes. While these codes address wind and impact resistance, they also set standards for energy efficiency and safety.

In Florida, the codes and regulations governing windows in new homes are primarily dictated by the Florida Building Code (FBC). The FBC sets forth comprehensive standards to ensure the safety, durability, and efficiency of windows in a variety of environmental conditions across the state. Here’s an in-depth look at the key aspects of Florida’s window codes for new homes:

1. Wind Load Requirements

Florida's susceptibility to hurricanes and strong winds necessitates strict wind load requirements for windows. The FBC outlines specific design pressures that windows must withstand based on their location within the state. These pressures are calculated to ensure windows can endure the force of high-speed winds and flying debris during storms. Coastal areas - including many areas in Sarasota and Manatee County - generally have higher wind load requirements compared to inland regions, reflecting the increased risk of hurricane exposure.

2. Impact Resistance

Coastal regions and certain inland areas designated as high-velocity hurricane zones (HVHZ) require windows to be impact-resistant or protected by impact-resistant coverings such as shutters or laminated glass. These measures are crucial for mitigating damage from wind-borne debris during hurricanes, enhancing the safety and resilience of homes in vulnerable areas.


3. Energy Efficiency

Energy efficiency standards outlined in the FBC aim to reduce heating and cooling costs and enhance comfort within homes. Windows must meet minimum U-factor and Solar Heat Gain Coefficient (SHGC) ratings, which vary depending on the climate zone within Florida. These ratings ensure that windows effectively insulate against heat transfer and minimize solar heat gain, contributing to overall energy savings and environmental sustainability.

4. Egress Requirements

Windows serving as emergency exits, known as egress windows, must comply with specific size and height requirements to facilitate safe exit in the event of a fire or other emergencies. These requirements are critical for ensuring occupant safety and compliance with building codes that prioritize life safety measures.

5. Installation Standards

Proper installation of windows is essential to their performance and longevity. The FBC mandates adherence to specific installation practices to prevent water intrusion, ensure structural integrity, and maintain energy efficiency. Correct installation techniques, including appropriate sealing and anchoring methods, are crucial for meeting code requirements and maximizing the effectiveness of windows in new homes.

6. Documentation and Compliance

Compliance with the FBC involves documentation and permitting processes to verify that windows installed in new homes meet all applicable codes and standards. Builders and contractors must submit documentation demonstrating compliance with wind load, impact resistance, energy efficiency, and egress requirements to local building authorities for review and approval.
