Certain Pella® windows can stop fast-moving baseballs and others can weather hurricane-force winds. How?
As far as hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.
Tests consist of blasting a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, if we could design a hurricane window with impact-resistant glass, surely we could come up with a fix that could halt home runs from Major League Baseball teams.
When Pella was contacted to help outfit a historic building near Wrigley Field with home run-resistant windows, that’s just what we did.
We overhauled our hurricane cannon to test the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would reconstruct the speed of a home run.
Our tempered glass weathered the hits best because it’s stronger and safer than generally used annealed glass.
All About Physics
It requires a speed of more than 100 mph and a height greater than 100 feet to send a baseball out of the park.
In Wrigley’s situation, we determined the baseballs would be going at about 60 mph upon hitting windows.
But we exceeded requirements and tested 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 hurling at your home, there are a variety of reasons to use durable, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an additional level of safety from their windows or patio doors. Or those who are raising the next great baseball player.
Consider the strengths and highlights of Pella tempered glass options:
- Toughened glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Usually shatters into small, square pieces as opposed to sharp shards if broken.
- Glass doesn’t fall 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 Traverse City at 231-538-2175. Or, schedule a free, in-home consultation online.
