Certain Pella® windows can halt speeding 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 thoroughly tested for impact resistance.
Tests consist of shooting a two-by-four at the window to ensure glass remains intact. We use our hurricane cannon to propel the wood, which covers 50 feet per second.
It Started with Hurricane Testing
We thought, if we could engineer a hurricane window with impact-resistant glass, surely we could come up with a resolution that could halt home runs from Major League Baseball teams.
When Pella was approached 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 shot baseballs from the cannon at an angle and speed that would reconstruct the speed of a home run.
Our tempered glass withstood the baseballs best because it’s stronger and safer than generally used annealed glass.
All About Physics
It warrants a speed surpassing 100 mph and a height exceeding 100 feet to launch a baseball out of the park.
In Wrigley’s situation, we determined 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 concerned about an MLB home run propelling toward your residence, 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 raising the next great baseball player.
Look at the strengths and highlights of Pella tempered glass options:
- Strong glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Usually shatters into small, square pieces 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 Mt. Pleasant at 989-317-2558. Or, request a free, in-home consultation online.
