Everything You Need to Know about Impact-resistant Windows

Impact-resistant windows, also known as laminated glass, hurricane windows, or impact windows, feature an interlayer design to withstand the force of high-speed winds. They also dampen sound and protect homes from ultraviolet rays that can damage photographs, floors, furniture, and carpets.

How Impact-Resistant Windows Work?

The laminated glass in these windows is made from two glass pieces reinforced with a flexible and strong polymer in between that remains intact even when the windows are shattered due to flying debris. This polymer layer also prevents laminated glass from breaking into large, sharp pieces that can be dangerous for anyone in the home.

Benefits of Impact-Resistant Windows

Some top benefits of installing impact-resistant windows are as follows:

• Energy Efficiency:

These windows' inherent insulation properties keep temperatures in check and prevent air leaks during summer and winter, thus reducing energy bills.

• Theft Prevention:

These windows make breaking into homes difficult because of the construction of several layers of glass.

• Noise-Free Home:

The PVB layer in hurricane windows absorbs outside noise and keeps storm debris away.

• Permanent Protection against storms and hurricanes:

Impact windows are extremely strong and protect against strong winds and heavy rain.

• UV Damage Protection:

Double glazing, low E glass and window tinting features of these windows reduce the damaging effects of ultra-violet rays.

Factors to Consider When Choosing Impact-Resistant Windows

• The design pressure of the window or the amount of pressure it can withstand during heavy storms.

• The window's SHGC or Solar Heat Gain Coefficient measures how well it can block solar heat. Find this information on the window's fenestration label.

• Window manufacturer is an important concern. Always get hurricane windows from recognised manufacturers, considering factors like price, timeline, structure type, and location.

• Consider the visible transmittance of the window or the amount of natural light it allows to pass through it.

• Also, ensure that the company you buy the window from offers superior-quality installation.

Installation Process

Here's a step-by-step guide on hurricane window installation:

• Remove your existing window from its frame after inspecting it for damage or rotting.

• Next, measure and remeasure varied dimensions before dry-fitting the impact window into the frame's empty opening. Dry fitting before caulking ensures you have bought the right-sized window.

• Now remove the entire unit and apply proper sealant to the external frame.

• Next, insert the window into the frame using a hammer or nail gun.

• For extra security, you can use silicone caulking on the edge of the frame. This ensures the window does not leak air or invite moisture during adverse weather conditions.

• Double-check all areas for proper sealing.

Maintenance and Care

With proper care and maintenance, the impact windows will provide several years of security and protection without getting damaged. Here's everything you must know about caring for and maintaining your hurricane windows:

• Deep clean the windows regularly by wiping down the frames and removing the window screens.

• The window seals, carefully engineered to keep excessive moisture, insects and dust out, may gradually wear with time. Therefore, check them periodically for signs of damage, like fog or condensation. If you notice any deterioration sign, replace the windows immediately.

• Since hurricane windows feature an exclusive construction, do not use abrasive materials, such as abrasive cleaners or paper towels, to clean them. Instead, use non-abrasive, gentle cleaners, microfiber towels, and a squeegee.

• Repair the windows occasionally, especially after a storm. Quick action repair is necessary if you notice chips, abrasions, or small cracks.

Cost Considerations

Impact windows can secure homes from wind and water damage and prevent theft, thanks to their multi-layer glass design. Hence, they cost twice as much as the standard, single-pane windows. Some key factors influencing the cost of hurricane windows include:

• Window shape and size:

Larger windows may require more labour and material, subsequently adding to the cost.

• The installation location of the windows:

Window installations in hard-to-reach areas or higher floors may be more expensive because of safety considerations and complexities.

• The type of glass used in the window frame:

Options range from laminated glass to insulated laminated glass that offers added noise reduction and energy efficiency.

• Frame material:

Options include wood, vinyl, and aluminium, each with varied benefits and price points. The most popular choice is an aluminium frame because of its durability and strength.

Home Insurance Implications

Major insurance companies recognise the value of hurricane windows and thus offer discounts on home insurance to those who upgrade to these windows. Many homeowners with impact window may also qualify for wind mitigation insurance rebates.

FAQs

1. Do impact windows work?

Yes, these windows are specifically tested and designed to offer hurricane protection by withstanding up to a category five hurricane and impacts of flying debris.

2. Is tempered glass impact-resistant?

No, although tempered glass is string than standard glass, it is not impact resistant.

3. Can impact glass break?

Yes, impact glass can easily withstand the pressure of a hurricane. Laminated glass may fracture if hit hard, but the impact glass in hurricane windows remains intact due to its high-strength polymer interlayer.

Conclusion

Impact-resistant windows are a boon for homeowners in areas prone to adverse weather conditions. By investing in them, you can safeguard your home or business and enjoy other benefits, such as reduced energy bills, insurance discounts, theft prevention, and UV protection. So, don't wait until it's late—protect your property with impact windows today!
