Certain Pella® windows can stop speeding baseballs and others can withstand 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 shooting a two-by-four at the window to ensure glass stays intact. We use our hurricane cannon to propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could design a hurricane window with impact-resistant glass, surely we could discover a resolution that could protect from home runs from Major League Baseball teams.
When Pella was contacted to help supply a historic building near Wrigley Field with home run-resistant windows, that’s just what we did.
We retrofitted 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 requires 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 situation, we determined the baseballs would be traveling at about 60 mph upon hitting 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 worried about an MLB home run hurling at your residence, there are a lot of reasons to select durable, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an added level of security from their windows or patio doors. Or those who are bringing up the next great baseball player.
Look at the benefits and highlights of Pella tempered glass options:
- Durable glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Generally breaks into small, square fragments as opposed to sharp shards if broken.
- Glass doesn’t break apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To find out more about impact windows and if they may be right for your home, call Pella of Beltsville at (301) 685-1715. Or, schedule a free, in-home consultation online.
