Impact Windows FAQ
What is an impact window?
Impact windows are windows designed to resist impact and violent wind speeds. Impact windows are typically two or three glass panels laminated together with a PVB interlayer within an aluminum or vinyl frame.
Can impact windows protect against tornadoes and hurricanes?
Yes, impact windows are tested to resist wind speed and pressures that are superior to category 5 hurricanes. Keep in mind that the most vulnerable structural components of your home are your window and door openings. The majority of damage comes from a breach from one of those openings, which can result in the worst-case scenario of a roof being blown off.
What's the difference between impact windows and hurricane windows?
There is no difference between impact windows and hurricane windows. Here in South Florida, impact windows are at times marketed as hurricane windows to have a greater appeal, but they are essentially the same thing.
Do impact windows reduce insurance fees?
Most insurances offer rebates for impact window and doors, but you should check with your provider.
What category of hurricane can impact windows withstand?
Impact windows are tested to withstand specific design pressures. For example, at the base thickness of 5/16", windows usually have a design pressure of +65/-65, which translates to 161 mph. Based on the Saffir-Simpson Hurricane Wind Scale (a scale used to categorize hurricanes), a category 5 hurricane has wind speeds of 157 MPH or higher, which means the window is rated to withstand a category 5 hurricane.
Should you board up impact windows for a hurricane?
It is not necessary to board up impact windows for a hurricane.
Do impact windows cost more than regular windows?
Yes, but the added security and protection can help you avoid unnecessary costs from property damage or burglary.
Do impact windows raise the value of a house?
Here in South Florida, they most definitely do. Speaking anecdotally based on our conversations with customers and real estate investors, impact windows are the best bang for your buck to raise your home's value.
Do impact windows protect against burglars?
Impact windows make it more challenging to break into a home and make it almost impossible to break in unnoticed. The double-pane glass and PVB interlayer make it extremely difficult to trespass and practically impossible to shatter. By the time they can breach into your home, you or a neighbor will likely have heard them banging against the glass. More often, they just give up. Impact windows are not a replacement for burglary alarms or any type of home security, but they can add another layer of protection.
