How to Tell if Your Windows Are Hurricane Proof?
Determining if your windows are truly hurricane proof requires a careful examination of their certifications, construction, and installation. Simply put, if your windows are properly certified and installed impact-resistant windows or are protected by properly installed hurricane shutters, they are likely providing the intended level of hurricane protection.
Understanding Hurricane-Resistant Windows
Hurricane-resistant windows, also known as impact-resistant windows, are designed to withstand the extreme forces of hurricanes. They are engineered to resist shattering and remain intact even when struck by flying debris. This is crucial because a breach in a window allows wind and rain to enter the building, potentially causing significant structural damage.
The Importance of Certification and Testing
The first step in determining if your windows are hurricane proof is to check for proper certifications. Look for windows that meet or exceed standards set by reputable organizations such as:
- Miami-Dade County Notice of Acceptance (NOA): Considered one of the most stringent certifications for hurricane-prone areas.
- Florida Building Code (FBC): Another key certification, demonstrating compliance with Florida’s building standards.
- American Society for Testing and Materials (ASTM): Look for specific ASTM standards related to impact resistance.
These certifications indicate that the windows have been rigorously tested and have met specific performance criteria related to wind resistance, impact resistance, and water infiltration. The presence of these certifications on the window’s labeling or from the manufacturer’s documentation provides strong evidence of its hurricane-resistant capabilities.
Examining the Construction of the Window
Beyond certifications, a close examination of the window’s construction can provide further clues:
- Laminated Glass: Hurricane-resistant windows typically feature laminated glass, which consists of two or more layers of glass bonded together with a strong interlayer, usually polyvinyl butyral (PVB). This interlayer holds the glass fragments together even when the glass is broken, preventing shattering.
- Reinforced Frames: The window frame is equally important. Look for frames made of durable materials like aluminum or reinforced vinyl. These materials are designed to withstand high wind pressures and prevent the glass from dislodging.
- Proper Installation: Even the best windows are ineffective if improperly installed. Professional installation by certified contractors is essential to ensure the window is securely anchored to the building’s structure.
Alternative Protection: Hurricane Shutters
If you don’t have impact-resistant windows, hurricane shutters provide an alternative method of protection. However, the effectiveness of shutters depends on their type, installation, and maintenance.
Types of Hurricane Shutters
There are several types of hurricane shutters available, each offering varying levels of protection:
- Accordion Shutters: These shutters fold to the side when not in use and can be quickly deployed during a storm.
- Roll-Down Shutters: These shutters roll down from a housing above the window and offer convenient operation.
- Bahama Shutters: These shutters provide both storm protection and aesthetic appeal.
- Colonial Shutters: Similar to Bahama shutters, but they fold outward from the sides of the window.
- Storm Panels: These panels are typically made of aluminum or polycarbonate and are attached to the window using tracks or fasteners.
Assessing Shutter Quality and Installation
Regardless of the type, ensure your shutters are:
- Certified: Like windows, shutters should be certified to meet relevant building codes and standards.
- Properly Installed: Professional installation is crucial for shutters to perform as intended. Check that the shutters are securely anchored to the building’s structure.
- Well-Maintained: Regularly inspect shutters for signs of damage, corrosion, or wear. Repair or replace any damaged components promptly.
FAQs: Your Guide to Hurricane Window Safety
1. What is the difference between impact-resistant windows and regular windows?
Impact-resistant windows are specifically designed to withstand the impact of flying debris and high winds during hurricanes. They feature laminated glass and reinforced frames. Regular windows do not have these features and are likely to shatter during a storm, allowing wind and rain to enter the building.
2. How do I find the certification information on my windows?
Certification information is typically found on a sticker or label located on the window frame. It may also be included in the manufacturer’s documentation. Look for markings indicating compliance with Miami-Dade NOA, Florida Building Code, or ASTM standards.
3. Can I install impact-resistant windows myself?
While DIY installation might seem tempting, it is strongly discouraged. Professional installation is crucial to ensure the windows are properly anchored to the building’s structure and meet all relevant building codes. Improper installation can compromise the window’s ability to withstand hurricane forces.
4. Are all laminated glass windows hurricane proof?
No. While laminated glass is a key component of hurricane-resistant windows, the specific type of laminate, the thickness of the glass, and the frame construction all contribute to the window’s overall performance. Simply having laminated glass does not guarantee hurricane resistance.
5. What is the lifespan of hurricane-resistant windows?
The lifespan of hurricane-resistant windows can vary depending on factors like the quality of the materials, the installation, and the climate. However, high-quality impact windows properly installed can last for 20 years or more.
6. Are there any tax incentives for installing hurricane-resistant windows?
Tax incentives can vary depending on your location and the current regulations. Check with your local government or a qualified tax professional to determine if any tax incentives are available for installing hurricane-resistant windows or shutters.
7. My shutters are old and rusty. Can I still use them?
Old and rusty shutters may not provide adequate protection during a hurricane. Inspect them carefully for signs of damage, corrosion, or wear. If they are significantly damaged, it is best to replace them with new, certified shutters.
8. How often should I inspect my hurricane shutters?
Inspect your hurricane shutters at least twice a year, ideally before and after hurricane season. Check for any signs of damage, corrosion, or wear and repair or replace any damaged components promptly.
9. Are storm panels as effective as impact-resistant windows?
Storm panels can provide a reasonable level of protection when properly installed, but they are generally not as convenient or aesthetically pleasing as impact-resistant windows. Impact windows offer continuous protection, while storm panels require manual installation before each storm.
10. Can I reinforce my existing windows to make them hurricane proof?
While some products claim to reinforce existing windows, they are generally not as effective as impact-resistant windows or hurricane shutters. These products may provide some level of protection against smaller debris, but they are unlikely to withstand the full force of a hurricane.
11. What is the cost difference between impact-resistant windows and regular windows?
Impact-resistant windows are typically more expensive than regular windows. However, the added cost is offset by the increased protection and potential savings on insurance premiums. The exact cost difference will vary depending on the window size, style, and manufacturer.
12. Will hurricane-resistant windows reduce noise and energy costs?
Yes, hurricane-resistant windows can provide added benefits beyond storm protection. The laminated glass and airtight seals can help reduce noise transmission and improve energy efficiency, leading to lower heating and cooling costs.
