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 involve blasting a two-by-four at the window to verify glass remains intact. We use our hurricane cannon to propel the wood, which covers 50 feet per second.
It Started with Hurricane Testing
We thought, if we could create a hurricane window with impact-resistant glass, surely we could find a solution that could stop home runs from Major League Baseball teams.
When Pella was contacted to help outfit a historic building outside of Wrigley Field with home run-resistant windows, that’s exactly what we did.
We retrofitted 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 withstood the hits best because it’s tougher 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 scenario, we determined the baseballs would be traveling at about 60 mph upon impact with 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 worried about an MLB home run propelling toward 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 added level of security from their windows or patio doors. Or those who are bringing up the next great baseball player.
Consider the advantages and highlights of Pella tempered glass options:
- Strong glass like what is used in car windows.
- Used where damages from broken glass are a concern.
- Normally fragments into small, square fragments instead of sharp shards if broken.
- Glass doesn’t fall 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 San Antonio at (210) 622-8673. Or, request a free, in-home consultation online.
