Certain Pella® windows can put a stop to fast-moving baseballs and others can withstand 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 include firing a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to launch the wood, which covers 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 find a solution that could halt 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 just what we did.
We retrofitted our hurricane cannon to test the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would mimic the force of a home run.
Our tempered glass resisted the baseballs best because it’s tougher 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 launch a baseball out of the park.
In Wrigley’s scenario, we determined the baseballs would be traveling at about 60 mph upon hitting windows.
But we went above and beyond and tested 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 propelling toward your residence, there are a lot of reasons to select durable, tempered glass in your Pella windows and doors.
It’s great 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:
- Toughened glass much like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Normally fragments into small, square fragments instead of sharp shards if broken.
- Glass doesn’t break apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To find out more about impact windows and if they may be right for your home, call Pella of Kalamazoo at 269-215-4157. Or, schedule a free, in-home consultation online.
