Certain Pella® windows can halt speeding baseballs and others can weather hurricane-force winds. How?
As far as hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.
Tests involve shooting a two-by-four at the window to ensure glass stays intact. We use our hurricane cannon to propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, 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 just what we did.
We retrofitted our hurricane cannon to evaluate the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would recreate the power of a home run.
Our tempered glass weathered the baseballs best because it’s stronger and safer than standard annealed glass.
All About Physics
It takes a speed of more than 100 mph and a height of more than 100 feet to launch a baseball out of the park.
In Wrigley’s case, we found the baseballs would be moving at about 60 mph upon striking windows.
But we did more than what was expected and checked 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 propelling toward your windows, there are a variety of reasons to use tough, tempered glass in your Pella windows and doors.
It’s ideal for homeowners who want an additional level of security from their windows or patio doors. Or those who are developing the next great baseball player.
Review the strengths and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Generally breaks into small, square pieces as opposed to 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 South Portland at 207-253-1856. Or, book a free, in-home consultation online.
