How Do I Know if I Have Hurricane Windows?

Determining whether you have hurricane windows is crucial for protecting your home from severe weather. Hurricane windows, also known as impact-resistant windows, are specifically designed to withstand high winds and flying debris, offering superior protection compared to standard windows during a hurricane.

Identifying Hurricane Windows: Key Indicators

The easiest way to identify hurricane windows is by looking for specific markings and features. Consider the following:

• Permanent Labeling: Look for a permanent label or etching directly on the glass. This label typically includes codes that indicate the window meets specific impact-resistant standards. These codes may include designations like ASTM E1996 and ASTM E1886, or Miami-Dade County Notice of Acceptance (NOA). The labeling will often be near a corner of the glass.
• Visible Interlayer: Many hurricane windows have a visible interlayer between the panes of glass. This interlayer, typically made of polyvinyl butyral (PVB) or SentryGlas®, holds the glass together even if it cracks. If you examine the edge of the glass, you may be able to see this thin layer.
• Thickness: Hurricane windows are significantly thicker than standard windows. Measure the overall thickness of the glass. If it is notably thicker than typical window glass, it is a strong indicator it is impact-resistant.
• Frame Material: While not definitive, some hurricane windows are installed with reinforced frames made of aluminum or vinyl. These frames are designed to withstand high wind pressures. Examine the frames for reinforcement or heavier gauge materials.
• Documentation: Check your home’s documentation, such as invoices from window installations, warranties, or homeowner’s insurance policies. These documents may explicitly state whether hurricane windows were installed.
• Professional Inspection: If you’re unsure after checking these indicators, consult a qualified window contractor or inspector. They can assess your windows and provide a definitive answer.

Understanding Impact-Resistant Standards

Knowing the relevant standards is vital in confirming hurricane window protection.

ASTM E1996 and ASTM E1886

These are two of the most common ASTM (American Society for Testing and Materials) standards for impact-resistant windows. They specify testing procedures to simulate the impact of windborne debris and the resulting pressure fluctuations. A window meeting these standards will be labelled as such.

Miami-Dade County Notice of Acceptance (NOA)

For homes in Florida, particularly in Miami-Dade County, a Miami-Dade County NOA is a crucial certification. It indicates that the window has met the stringent requirements of Miami-Dade County’s building codes, known for their rigorous hurricane protection standards.

Frequently Asked Questions (FAQs)

FAQ 1: What’s the difference between hurricane windows and hurricane shutters?

Hurricane windows offer permanent protection, being constantly in place. Hurricane shutters, on the other hand, are installed before a storm and removed afterward. Windows provide convenience and aesthetics, while shutters offer an alternative for existing windows or situations where cost is a major factor.

FAQ 2: Can I install hurricane windows myself, or do I need a professional?

While it’s technically possible to install hurricane windows yourself, it’s highly recommended to hire a qualified professional. Proper installation is critical for the windows to perform as intended during a hurricane. Incorrect installation can compromise their impact resistance and lead to water intrusion or structural damage.

FAQ 3: Are hurricane windows more expensive than regular windows?

Yes, hurricane windows are generally more expensive than standard windows due to the specialized materials and construction required to meet impact-resistant standards. However, the added protection, potential insurance discounts, and long-term peace of mind can make them a worthwhile investment.

FAQ 4: Do hurricane windows protect against noise?

Yes, hurricane windows often provide improved sound insulation compared to regular windows. The thicker glass and interlayer help to dampen external noise, creating a quieter indoor environment.

FAQ 5: Will hurricane windows increase my home’s value?

Yes, installing hurricane windows can increase your home’s value, especially in hurricane-prone areas. They are a desirable feature for potential buyers, providing peace of mind and protection against severe weather.

FAQ 6: How long do hurricane windows last?

With proper maintenance, hurricane windows can last for 20 years or more. The lifespan depends on factors like the quality of the windows, the climate, and the frequency of exposure to severe weather events.

FAQ 7: What kind of maintenance do hurricane windows require?

Hurricane windows require minimal maintenance. Regularly clean the glass and frames with mild soap and water. Inspect the windows periodically for any signs of damage, such as cracks or seal failure. Lubricate moving parts as needed.

FAQ 8: Can I get hurricane windows for sliding glass doors?

Yes, hurricane-resistant sliding glass doors are available. They are designed and tested to meet the same impact-resistant standards as hurricane windows, providing protection against high winds and flying debris.

FAQ 9: Do hurricane windows qualify for insurance discounts?

Yes, many insurance companies offer discounts to homeowners who install hurricane windows. The amount of the discount varies depending on the insurance company and the specific windows installed. Check with your insurance provider for details.

FAQ 10: What if my hurricane window cracks during a storm?

Hurricane windows are designed to crack but not shatter. The interlayer holds the glass fragments in place, preventing them from becoming projectiles and protecting the interior of your home. After the storm, contact a professional to repair or replace the damaged window.

FAQ 11: Can I retrofit existing windows with hurricane protection?

While replacing existing windows with hurricane windows is the most effective solution, you can retrofit them with hurricane shutters or impact-resistant film. However, these options may not offer the same level of protection as hurricane windows.

FAQ 12: Where can I find reputable installers of hurricane windows?

To find reputable installers, check with your local Better Business Bureau, search online directories, and ask for referrals from friends or neighbors. Be sure to verify the installer’s license and insurance before hiring them. Get multiple quotes and compare the quality of the windows and the installation services offered.

By carefully examining your windows and understanding the key indicators, you can determine whether you have hurricane windows and ensure your home is adequately protected against severe weather. Consulting with a professional is always recommended for a definitive assessment.
