Certain Pella® windows can stop 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 consist of shooting a two-by-four at the window to make sure glass remains intact. We use our hurricane cannon to fire the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We thought, if we could create a hurricane window with impact-resistant glass, surely we could find a solution that could halt 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 just 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 speed of a home run.
Our tempered glass resisted the hits best because it’s tougher and safer than standard annealed glass.
All About Physics
It requires a speed surpassing 100 mph and a height exceeding 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 impact with windows.
But we did more than what was expected and evaluated 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 home, there are a lot of reasons to use 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 raising the next great baseball player.
Consider the benefits and highlights of Pella tempered glass options:
- Strong glass much like what is used in car windows.
- Used where damages from broken glass are a concern.
- Normally fragments into small, square fragments rather than sharp shards if broken.
- Glass doesn’t break 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 Baltimore at 301-637-0762. Or, request a free, in-home consultation online.
