Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can stop 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 rigorously tested for impact resistance.
Tests consist of blasting a two-by-four at the window to make sure glass keeps intact. We use our hurricane cannon to fire the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could create a hurricane window with impact-resistant glass, surely we could come up with a fix that could halt home runs from Major League Baseball teams.
When Pella was asked to help outfit a historic building near Wrigley Field with home run-resistant windows, that’s exactly what we did.
We overhauled 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 speed of a home run.
Our tempered glass withstood 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 of more than 100 feet to shoot a baseball out of the park.
In Wrigley’s situation, we found the baseballs would be traveling at about 60 mph upon hitting windows.
But we exceeded requirements 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 being launched at your residence, there are a lot of reasons to select strong, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an added level of protection 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:
- Toughened glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Normally fragments into small, square pieces instead of sharp shards if broken.
- Glass doesn’t come apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To learn more about impact windows and if they may be right for your home, call Pella of Kelowna at 250-863-7902. Or, schedule a free, in-home consultation online.
