Certain Pella® windows can stop speeding baseballs and others can resist hurricane-force winds. How?
When it comes to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are rigorously tested for impact resistance.
Tests involve blasting a two-by-four at the window to verify glass keeps intact. We use our hurricane cannon to fire the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We figured, if we could create a hurricane window with impact-resistant glass, surely we could find a resolution that could halt home runs from Major League Baseball teams.
When Pella was approached to help outfit a historic building by 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 shot baseballs from the cannon at an angle and speed that would reconstruct the force of a home run.
Our tempered glass withstood the baseballs best because it’s tougher and safer than standard annealed glass.
All About Physics
It takes 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 scenario, we determined the baseballs would be going at about 60 mph upon striking windows.
But we did more than what was expected and checked impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not thinking about an MLB home run hurling at your residence, there are a variety of reasons to select tough, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an extra level of security from their windows or patio doors. Or those who are developing the next great baseball player.
Look at the benefits and highlights of Pella tempered glass options:
- Toughened glass much like what is used in car windows.
- Used where damages from broken glass are a concern.
- Normally fragments into small, square fragments instead of 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 Murray at 270-216-5253. Or, schedule a free, in-home consultation online.
