Certain Pella® windows can stop flying baseballs and others can resist hurricane-force winds. How?
In regard to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are thoroughly tested for impact resistance.
Tests include shooting a two-by-four at the window to make sure glass remains intact. We use our hurricane cannon to launch 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 fix that could stop 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 test the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would recreate the speed of a home run.
Our tempered glass resisted the home runs best because it’s tougher and safer than standard annealed glass.
All About Physics
It warrants a speed of more than 100 mph and a height greater than 100 feet to send a baseball out of the park.
In Wrigley’s scenario, we learned the baseballs would be traveling at about 60 mph upon impact with windows.
But we exceeded requirements 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 residence, there are a variety of reasons to select durable, 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 bringing up the next great baseball player.
Look at the advantages and highlights of Pella tempered glass options:
- Durable glass similar to what is used in car windows.
- Used where injuries from broken glass are a concern.
- Normally fragments into small, square fragments rather than sharp shards if broken.
- Glass doesn’t come 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 Northern Virginia at 571-292-3519. Or, schedule a free, in-home consultation online.
