Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can put a stop to flying 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 include firing a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to launch the wood, which travels 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 discover a fix that could stop home runs from Major League Baseball teams.
When Pella was contacted to help supply a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.
We overhauled 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 speed of a home run.
Our tempered glass resisted the hits best because it’s tougher and safer than generally used annealed glass.
All About Physics
It warrants a speed faster than 100 mph and a height exceeding 100 feet to shoot a baseball out of the park.
In Wrigley’s case, we found the baseballs would be going at about 60 mph upon impact with windows.
But we did more than what was expected 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 choose tough, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an additional level of protection from their windows or patio doors. Or those who are bringing up the next great baseball player.
Review the strengths 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 parts 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 learn more about impact windows and if they may be right for your home, call Pella of Edmonton at 780-439-9344. Or, request a free, in-home consultation online.
