Certain Pella® windows can halt flying baseballs and others can resist hurricane-force winds. How?
As far as hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are thoroughly tested for impact resistance.
Tests involve firing a two-by-four at the window to ensure glass stays intact. We use our hurricane cannon to propel the wood, which travels 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 solution that could halt home runs from Major League Baseball teams.
When Pella was contacted to help equip a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.
We retrofitted our hurricane cannon to test the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would reconstruct the force of a home run.
Our tempered glass resisted the baseballs best because it’s more durable 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 launch a baseball out of the park.
In Wrigley’s scenario, we determined the baseballs would be moving at about 60 mph upon impact with windows.
But we went above and beyond and evaluated 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 being launched at your residence, there are a lot of reasons to choose tough, 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 developing the next great baseball player.
Consider the benefits and highlights of Pella tempered glass options:
- Durable glass much like what is used in car windows.
- Used where damages from broken glass are a concern.
- Generally breaks 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 Roanoke at 540-466-1918. Or, schedule a free, in-home consultation online.
