Certain Pella® windows can stop fast-moving 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 involve blasting a two-by-four at the window to make sure glass remains intact. We use our hurricane cannon to fire the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could create a hurricane window with impact-resistant glass, surely we could come up with a resolution that could stop home runs from Major League Baseball teams.
When Pella was contacted to help equip a historic building by Wrigley Field with home run-resistant windows, that’s just what we did.
We retrofitted our hurricane cannon to evaluate 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 resisted the hits best because it’s stronger and safer than generally used annealed glass.
All About Physics
It takes 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 learned the baseballs would be going at about 60 mph upon hitting windows.
But we went above and beyond and tested 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 propelling toward your residence, there are many reasons to use tough, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an additional 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:
- Durable glass much like what is used in car windows.
- Used where injuries from broken glass are a concern.
- Normally fragments into small, square parts 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 discover more about impact windows and if they may be right for your home, call Pella of Nashville at 615-348-8786. Or, book a free, in-home consultation online.
