Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can stop speeding baseballs and others can withstand hurricane-force winds. How?
As far as hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.
Tests include blasting a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to launch the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, if we could design a hurricane window with impact-resistant glass, surely we could find a resolution that could stop home runs from Major League Baseball teams.
When Pella was approached to help outfit a historic building near Wrigley Field with home run-resistant windows, that’s precisely what we did.
We modified our hurricane cannon to test 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 resisted the home runs best because it’s more durable and safer than generally used annealed glass.
All About Physics
It takes a speed surpassing 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 moving at about 60 mph upon hitting windows.
But we did more than what was expected and tested 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 propelling toward your residence, there are a variety of reasons to use 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.
Review the strengths and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Normally fragments into small, square parts rather than 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 Jackson at 307-733-0535. Or, book a free, in-home consultation online.
