Certain Pella® windows can stop speeding baseballs and others can weather hurricane-force winds. How?
When it comes to 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 make sure glass stays intact. We use our hurricane cannon to fire the wood, which covers 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 find a resolution that could protect from home runs from Major League Baseball teams.
When Pella was asked to help equip a historic building outside of Wrigley Field with home run-resistant windows, that’s just what we did.
We overhauled our hurricane cannon to experiment on the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would reconstruct the force of a home run.
Our tempered glass resisted the home runs best because it’s tougher and safer than commonly used annealed glass.
All About Physics
It warrants a speed of more than 100 mph and a height of more than 100 feet to launch a baseball out of the park.
In Wrigley’s scenario, we found the baseballs would be traveling at about 60 mph upon hitting windows.
But we went above and beyond 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 being launched at your home, there are many reasons to choose tough, tempered glass in your Pella windows and doors.
It’s ideal 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.
Consider the advantages and highlights of Pella tempered glass options:
- Toughened glass similar to what is used in car windows.
- Used where injuries from broken glass are a concern.
- Generally breaks into small, square fragments rather than 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 Springfield at 217-793-0550. Or, request a free, in-home consultation online.
