Certain Pella® windows can put a stop to fast-moving baseballs and others can weather 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 propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could create a hurricane window with impact-resistant glass, surely we could come up with a fix that could halt home runs from Major League Baseball teams.
When Pella was contacted to help outfit a historic building by 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 speed of a home run.
Our tempered glass withstood the hits best because it’s stronger and safer than commonly used annealed glass.
All About Physics
It warrants 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 found the baseballs would be going at about 60 mph upon hitting 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 being launched at your home, there are a variety of reasons to select strong, tempered glass in your Pella windows and doors.
It’s good 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.
Consider the strengths and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where cuts from broken glass are a concern.
- Normally fragments into small, square parts 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 Grand Rapids at 616-201-0206. Or, schedule a free, in-home consultation online.
