Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can halt speeding baseballs and others can resist hurricane-force winds. How?
In regard to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.
Tests consist of shooting a two-by-four at the window to make sure glass remains intact. We use our hurricane cannon to fire the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We figured, if we could design a hurricane window with impact-resistant glass, surely we could find a resolution that could halt home runs from Major League Baseball teams.
When Pella was approached to help outfit a historic building outside of Wrigley Field with home run-resistant windows, that’s exactly what we did.
We modified our hurricane cannon to evaluate 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 withstood the baseballs best because it’s more durable and safer than commonly used annealed glass.
All About Physics
It takes a speed of more than 100 mph and a height greater than 100 feet to shoot a baseball out of the park.
In Wrigley’s situation, we learned the baseballs would be traveling at about 60 mph upon striking windows.
But we did more than what was expected and evaluated impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not thinking about an MLB home run being launched at your residence, there are a variety of reasons to choose strong, 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.
Review the benefits and highlights of Pella tempered glass options:
- Strong glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Normally fragments into small, square fragments rather than sharp shards if broken.
- Glass doesn’t break 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 Casper at 307-234-1518. Or, request a free, in-home consultation online.
