Certain Pella® windows can stop fast-moving baseballs and others can resist 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 include blasting a two-by-four at the window to make sure glass stays intact. We use our hurricane cannon to fire the wood, which moves 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 discover a fix that could stop home runs from Major League Baseball teams.
When Pella was asked to help supply a historic building outside of 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 fired baseballs from the cannon at an angle and speed that would mimic the speed of a home run.
Our tempered glass resisted the home runs best because it’s tougher and safer than standard annealed glass.
All About Physics
It warrants a speed faster than 100 mph and a height of more than 100 feet to launch a baseball out of the park.
In Wrigley’s situation, we found the baseballs would be traveling at about 60 mph upon striking windows.
But we went above and beyond and checked 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 windows, 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 extra level of safety from their windows or patio doors. Or those who are bringing up the next great baseball player.
Consider the strengths and highlights of Pella tempered glass options:
- Durable glass much like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Generally breaks into small, square pieces as opposed to 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 Providence at 508-413-3004. Or, schedule a free, in-home consultation online.
