Certain Pella® windows can stop speeding 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 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 travels 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could engineer 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 contacted to help equip a historic building outside of Wrigley Field with home run-resistant windows, that’s just what we did.
We modified our hurricane cannon to test the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would mimic the power of a home run.
Our tempered glass resisted the hits best because it’s stronger and safer than standard 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 determined the baseballs would be going 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 concerned about an MLB home run hurling at your home, there are a variety of reasons to select strong, tempered glass in your Pella windows and doors.
It’s ideal for homeowners who want an extra level of safety from their windows or patio doors. Or those who are developing the next great baseball player.
Consider the benefits and highlights of Pella tempered glass options:
- Strong glass much like what is used in car windows.
- Used where injuries from broken glass are a concern.
- Generally breaks into small, square pieces 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 discover more about impact windows and if they may be right for your home, call Pella of North Carolina at 866-539-4196. Or, schedule a free, in-home consultation online.
