Certain Pella® windows can halt flying 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 meticulously tested for impact resistance.
Tests involve firing a two-by-four at the window to ensure glass remains intact. We use our hurricane cannon to propel the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We figured, if we could engineer a hurricane window with impact-resistant glass, surely we could discover a solution that could halt home runs from Major League Baseball teams.
When Pella was contacted to help outfit a historic building near Wrigley Field with home run-resistant windows, that’s precisely what we did.
We retrofitted our hurricane cannon to experiment on the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would recreate the force 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 requires a speed faster than 100 mph and a height greater than 100 feet to launch a baseball out of the park.
In Wrigley’s scenario, 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 being launched at your windows, there are many reasons to choose tough, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an extra level of protection from their windows or patio doors. Or those who are bringing up the next great baseball player.
Look at the strengths and highlights of Pella tempered glass options:
- Strong glass much like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Generally breaks 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 find out more about impact windows and if they may be right for your home, call Pella of Cape Cod at 508-638-5897. Or, request a free, in-home consultation online.
