impact-resistant windows

Do you reside in an area with frequent rain, hail, or thunderstorms? In California, rain and thunderstorms are common and can damage the integrity of the windows in your home. Impact-resistant windows might be the right choice if you live in areas with these climatic situations. 

Impact-resistant windows (also known as hurricane impact-resistant windows) are designed to stand tough against flying debris and high winds during storms. Unlike regular windows that can easily shatter, these windows have special features like a double layer of glass and heavy-duty frames that keep them intact even when hit hard. 

In this blog post, we’ll go over everything about impact-resistant windows, including what they are and how they are rated. 

If you are unsure about the right windows for your building, call us at (951) 501-4479. Our experts are here to listen and answer your questions. 

👉 How Does An Impact-Resistant Window Work?

Impact-Resistant Window Work

Impact-resistant windows are manufactured differently than regular windows. At their core, these windows feature a multi-layer construction that’s key to their strength and durability. 

Most impact-resistant windows have an additional layer sandwiched between two layers of glass. This middle layer, made of a material called polyvinyl butyral (PVB), gives impact-resistant windows their unique properties.

When debris strikes an impact-resistant window during a storm, the outer layer of glass might crack, but it won’t shatter. Instead, the PVB layer holds the broken pieces in place, preventing them from flying into your home.

This design keeps wind and rain from entering your house, even if the outer layer is damaged.

The benefits of impact-resistant windows extend beyond storm protection. The PVB layer acts as a noise barrier, reducing outdoor sound, and it blocks harmful UV rays, protecting your furniture and carpets from sun damage.

👉 Why Do You Need Impact-Resistant Windows?

Impact-resistant windows offer various qualities that make them a great choice for both commercial and residential buildings, including: 

#1 Improved Home Security

Impact-resistant windows don’t just protect you from weather, they also deter burglars. The tough construction of these windows makes them hard to break even with considerable force.

This added layer of security will provide your home with better protection against intruders.

#2 Energy Efficiency

Impact-resistant windows provide excellent insulation, helping to maintain a comfortable temperature inside your home year-round. 

#3 Noise Reduction

If you live in a noisy area, impact-resistant windows can be helpful. The multi-layer design of these windows provides a quieter and more peaceful environment inside your home by blocking outside noise. 

Whether it’s traffic, construction, or noisy neighbors, you’ll notice a significant reduction in sound penetration.

#4 UV Protection

Impact-resistant windows may block up to 99% of harmful UV rays, helping to preserve your belongings and maintain the beauty of your home’s interior. 

This feature is particularly valuable if you live in a sunny climate where UV damage is a constant concern.

#5 Potential Insurance Benefits

You might get discounts on your homeowner’s insurance premiums after installing these windows. While the specifics vary by insurer and location, you can discuss it with your insurance provider to see what savings are available.

#6 Protection from Extreme Weather

If you live in an area prone to hurricanes or severe storms, impact-resistant windows are a smart investment. 

These windows can stand tough against wind speeds up to 200 mph, depending on the brand, and protect your home from flying debris. 

What Are The Security Standards and Specifications for Impact-Resistant Windows?

So now that you have an idea about impact-resistant windows and their benefits, it is crucial to understand the security standards and certifications that make these windows impact-resistant.

➡ ASTM Guidelines For Impact-Resistant Windows

Impact-resistant windows must be rated and labeled per specific standards set by the American Society for Testing and Materials (ASTM). The two key standards are:

1. ASTM E 1996 

This standard specifies the performance of exterior windows, doors, curtain walls, and storm shutters impacted by windborne debris in hurricanes.

2. ASTM E 1886

This standard outlines the testing method for the performance of exterior windows, curtain walls, storm shutters, and doors impacted by missiles and exposed to cyclic pressure differentials.

Additionally, windows may be certified under AAMA 506-23, which is a standard set by the Fenestration & Glazing Industry Alliance (FGIA) for hurricane impact and cycle testing.

When shopping for impact-resistant windows, always look for labels or certifications indicating compliance with these standards. This ensures that the windows have undergone rigorous testing to prove their ability to withstand severe weather conditions.

➡ General California Building Code Guidelines For Windows

If you’re in California, there are additional guidelines to consider when installing new  windows:

#1 Glass Edge Clearance

For fixed openings with glass higher than 3 feet, the edge clearance on all sides must be at least 3/16 inch.  

#2 Resilient Setting Material

Windows must use resilient setting materials, such as preformed rubber or vinyl plastic gaskets. These materials help absorb shock and prevent glass breakage.

#3 Safety Glass Requirements

Windows that are within 36 inches of a walkway, have a bottom edge less than 18 inches above the ground, or have a top edge greater than 36 inches above the ground must use safety glass. Additionally, for fixed or operable panels larger than 9 square feet, safety glass is required. 

How Much Do Impact-Resistant Windows Cost?

The average cost of impact-resistant windows can range anywhere between $1,900 to $10,000. Initially, you’ll find that impact-resistant windows are more expensive than traditional windows. 

The exact cost can vary depending on factors like window size, frame material, and the specific features you choose.

However, it’s crucial to view this as an investment in your home’s safety and efficiency. 

Over time, the energy savings from improved insulation can recover a significant portion of the initial cost. Additionally, the potential insurance discounts and the money you’ll save by not needing to buy and install storm shutters or plywood during severe weather can further justify the cost.

Final Thoughts

After installing impact-resistant windows, you’ll notice an immediate difference in your home’s comfort and security. 

During storms, you’ll no longer need to scramble to board up your windows or worry about flying debris. The reduced noise from outside will create a more peaceful living environment, and you may even see a decrease in your energy bills.

It’s important to note that while impact-resistant windows are extremely durable, they’re not indestructible. Regular maintenance, such as cleaning and checking seals, will help ensure they continue to perform optimally for years to come.

A. There are a few ways to check whether your existing windows are impact-resistant:
Look for a permanent mark or label on the window, usually in one of the corners, that indicates it meets impact resistance standards. You might also see a label mentioning laminated glass or references to hurricane codes.
Another major sign is the thickness of the glass. Impact-resistant windows typically have thicker glass than standard windows.

A. While you might want to save money by installing impact-resistant windows yourself, professional installation is crucial for ensuring their effectiveness. These windows are heavier than standard windows and often require structural reinforcements to the window frames and surrounding walls.
During the installation process, the experts will carefully remove your old windows, prepare the openings, and install the new impact-resistant windows. They’ll also make sure that all seals are tight and that the windows are properly anchored to withstand high winds and impacts.
