What is the Difference Between Impact Windows and Hurricane Windows?

Introduction

Living in a hurricane-prone area requires taking precautions to protect your home and loved ones. Two popular options for safeguarding your property are impact windows and hurricane windows. While these terms are often used interchangeably, they are not the same. In this article, we will explore the key differences between impact windows and hurricane windows, helping you make an informed decision about which option best suits your needs.

Impact Windows

Impact windows, also known as impact-resistant windows or storm windows, are specially designed to withstand the strong winds and debris associated with hurricanes. These windows feature a laminated glass that is held together by an interlayer, typically made of polyvinyl butyral (PVB). The interlayer keeps the glass intact even if it shatters, preventing shards from flying into your home, which can cause injuries and further damage.

One of the significant advantages of impact windows is their ability to provide continuous protection against hurricanes, even during power outages. Since the glass remains intact, intruders find it difficult to break into your home, enhancing your security. Additionally, impact windows offer excellent noise reduction, heat insulation, and UV protection, making them a valuable investment for homeowners.

Hurricane Windows

Hurricane windows, also known as hurricane-proof windows or high-impact windows, are specifically engineered to withstand the extreme forces generated by hurricanes. These windows undergo rigorous testing to ensure their ability to resist high winds, flying debris, and intense pressure changes during a storm.

Unlike impact windows, hurricane windows feature an interlayer made of ethylene-vinyl acetate (EVA) or thermoplastic polyurethane (TPU). This interlayer is sandwiched between two layers of glass, creating a strong barrier against the elements. If the glass breaks, the interlayer adheres to the shards, preventing them from dislodging or scattering.

Key Differences

While both impact windows and hurricane windows provide protection during severe weather events, they have a few key differences:

1. Construction

The construction of impact windows involves a single layer of glass with a PVB interlayer, while hurricane windows consist of two layers of glass with an EVA or TPU interlayer.

2. Resistance

Hurricane windows are specifically designed to withstand higher wind speeds and pressure changes compared to impact windows.

3. Shattering

If the glass in impact windows shatters, it remains intact due to the PVB interlayer, while hurricane windows have an interlayer that adheres to the shards, preventing them from dislodging.

4. Security

Impact windows provide added security benefits due to their shatter-resistant glass, which is difficult to break even for potential intruders.

5. Noise Reduction

Both impact windows and hurricane windows offer excellent noise reduction capabilities compared to standard windows, but impact windows generally provide slightly better noise reduction due to their laminated glass construction.

Conclusion

When considering impact windows versus hurricane windows, it’s important to evaluate your specific needs, budget, and the level of protection required. Impact windows offer continuous protection, enhanced security, and additional benefits such as noise reduction and UV protection. On the other hand, hurricane windows are designed to withstand extreme weather conditions and provide superior resistance to high winds and pressure changes. Consulting with a professional in the field can help you make an informed decision that suits your unique circumstances.

Frequently Asked Questions

1. Are impact windows hurricane-proof?

While impact windows are designed to withstand hurricane-force winds and flying debris, they are not considered completely hurricane-proof. However, they provide a high level of protection compared to standard windows.

2. Can I install impact or hurricane windows myself?

It is recommended to hire a professional for the installation of impact or hurricane windows. Proper installation is crucial to ensure the windows perform as intended during a hurricane or severe weather event.

3. Do impact windows provide energy efficiency?

Yes, impact windows offer excellent energy efficiency. Their laminated glass construction and interlayer help to reduce heat transfer, resulting in lower energy consumption and reduced utility bills.

4. How long do impact windows last?

The lifespan of impact windows can vary depending on various factors such as manufacturer, maintenance, and climate conditions. However, high-quality impact windows can last for decades with proper care.

5. Are impact or hurricane windows eligible for insurance discounts?

Many insurance companies offer discounts on homeowners’ insurance premiums for installing impact or hurricane windows. Contact your insurance provider to inquire about potential discounts and requirements.
