Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can stop speeding baseballs and others can weather 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 consist of firing a two-by-four at the window to make sure glass stays intact. We use our hurricane cannon to launch 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 find a fix that could stop home runs from Major League Baseball teams.
When Pella was asked to help equip a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.
We modified our hurricane cannon to evaluate 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 tougher and safer than generally used annealed glass.
All About Physics
It takes a speed of more than 100 mph and a height exceeding 100 feet to send 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 exceeded requirements and checked 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 windows, there are a variety of reasons to use tough, tempered glass in your Pella windows and doors.
It’s great 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.
Review the benefits and highlights of Pella tempered glass options:
- Durable glass much like what is used in car windows.
- Used where injuries from broken glass are a concern.
- Generally breaks into small, square parts 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 Eau Claire at 715-836-9301. Or, schedule a free, in-home consultation online.
