While impact windows aren't indestructible, they are very hard to break. To get through, a burglar would create a ruckus and likely be caught. Breaking through impact windows typically proves to be considerable work and energy, forcing burglars to move on.
In the general sense, impact-resistant windows are not a 100% deterrent to crime. However, they are far harder to break and can make gaining entry to your home far more difficult for burglars. The reason for this is due to the unique design impact windows use.
The biggest drawback of impact windows is their cost, which is why they are typically only used in high-risk areas. However, it is beneficial in the long run because they last much longer than other types of glass.
Impact Windows Are Just for Looks
Knowing that your home has permanent protection against hurricanes, tornadoes, and other storms at any given time also provides peace of mind. Ultimately, hurricane-resistant windows are capable of withstanding winds of up to 200 miles per hour.
Installing these windows significantly lowers your chances of major damage to your home. Hurricane impact windows have advanced to the point where they can withstand Category 5 wind conditions, and the debris that goes with it. So next time a hurricane hits your neighborhood, don't be caught unprotected.
While replacing your home's windows is a costly project, it can pay off by adding value to your home. According to the Remodeling's 2023 Cost vs. Value report, replacing vinyl windows adds an average of $13,766 in value to a home — about 69% of the cost of the project.
Hurricane impact windows definitely add value to your home. It may not be immediate monetary value, but you can save hundreds in energy costs and potential storm damage.
Many impact windows are rated to function properly from 10 to 25 years, depending on the brand and materials.
Most older homes have windows that do not latch, close, or operate properly which can be a nuisance and could also be dangerous in hurricanes; even with hurricane shutters on. With impact hurricane windows and doors you do not need hurricane shutters.
Category 4 Hurricane
These winds can destroy a home's roof structure and exterior walls, topple most trees and power lines, and cause damage that will last for months. Category 4 hurricanes cause extreme harm to glass windows and doors for homes and businesses.
Impact windows are able to withstand all wind-blown debris, forced entry attempts, and wind speeds of up to 175 mph. This is the equivalent wind speed of a Category 5 hurricane.
A Category 4 hurricane will blow out most windows on high-rise buildings, uproot most trees and will likely down many power lines. Power outages can last for weeks or even months after storms of this level.
Hurricane Windows & Impact Windows Are Not the Same
To be considered a hurricane window, a product simply needs to provide a certain level of wind resistance. An impact window, on the other hand, will offer wind resistance as well as protection from impacts.
In plain terms, yes, impact glass can break. However, as these glass structures receive impact, the inner layer of PVB keeps the structure from breaking down—it keeps the window standing even though the glass shatters. There are varying types of impact glass.
Impact glass is comprised of two different types of glass, one of which is called tempered glass, also known as safety glass. Tempered glass is manufactured in a way that makes it up to four times stronger than annealed (standard) glass.
Because impact windows can help protect your home from high winds and flying debris, your insurance company may give you a discount on your premium. In some cases, the discount can be as much as 20 to 30 percent. That can add up to significant savings over the life of your policy.
No, impact windows are not soundproof. If there are extremely loud noises outside, like a fire truck or scream, you're likely to hear them. And the closer the noise is to the window, the more likely you are to hear it. According to PGT, there's a 65% reduction in sound with PGT impact windows.
Impact windows are made from laminated glass or laminated insulating glass, which helps provide insulation and protection from unwanted heat loss and heat gain.
Installation of hurricane-proof windows can actually give you an excellent return on your investment – between 75-85% – if you plan to sell or even refinance your home in the near future.
The FBC requires windows to be impact-resistant or protected with shutters if located within one mile of the coast where the wind speed is 140 mph or greater during a storm. (Of course, even if your home is not located in this area, impact windows are getting to be the norm in all of South Florida.)
Hurricane impact windows, while stronger and more water resistant than ordinary windows, will still let wind driven rain intrude. Resistance to water leakage is one of the performance standards hurricane windows are tested for to ensure they meet national standard requirements.
While old windows might still be functional, there's a good chance they're not very efficient. Windows that are over 20 years old should be replaced. If you've lived in your home for decades and have never replaced the windows, they are likely original to the house.
