Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can halt fast-moving baseballs and others can withstand hurricane-force winds. How?
When it comes to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are thoroughly tested for impact resistance.
Tests involve firing a two-by-four at the window to make sure glass stays intact. We use our hurricane cannon to launch the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We thought, if we could create a hurricane window with impact-resistant glass, surely we could come up with a fix that could stop home runs from Major League Baseball teams.
When Pella was asked to help outfit a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.
We overhauled our hurricane cannon to test the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would recreate the force of a home run.
Our tempered glass weathered the hits best because it’s stronger and safer than generally used annealed glass.
All About Physics
It requires a speed of more than 100 mph and a height exceeding 100 feet to launch a baseball out of the park.
In Wrigley’s situation, we found the baseballs would be going at about 60 mph upon hitting windows.
But we exceeded requirements and tested impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not worried about an MLB home run being launched at your residence, there are a lot of reasons to use tough, tempered glass in your Pella windows and doors.
It’s ideal for homeowners who want an extra level of protection from their windows or patio doors. Or those who are developing the next great baseball player.
Look at the benefits and highlights of Pella tempered glass options:
- Strong glass much like what is used in car windows.
- Used where damages from broken glass are a concern.
- Usually shatters into small, square fragments instead of sharp shards if broken.
- Glass doesn’t fall apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To learn more about impact windows and if they may be right for your home, call Pella of Owensboro at 270-684-3028. Or, request a free, in-home consultation online.
