Certain Pella® windows can put a stop to fast-moving baseballs and others can weather 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 shooting a two-by-four at the window to verify glass keeps intact. We use our hurricane cannon to launch the wood, which covers 50 feet per second.
It Started with Hurricane Testing
We figured, if we could design a hurricane window with impact-resistant glass, surely we could come up with a solution that could protect from 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 just what we did.
We retrofitted our hurricane cannon to experiment on the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would mimic the force of a home run.
Our tempered glass weathered the home runs best because it’s more durable 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 moving at about 60 mph upon hitting 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 propelling toward your windows, there are many reasons to choose tough, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an added level of safety from their windows or patio doors. Or those who are raising the next great baseball player.
Review the strengths 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.
- 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 Albany at 518-414-5302. Or, request a free, in-home consultation online.
