Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can halt flying baseballs and others can resist hurricane-force winds. How?
In regard 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 ensure glass keeps 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 fix that could stop home runs from Major League Baseball teams.
When Pella was approached to help supply a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.
We modified our hurricane cannon to test the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would mimic the speed of a home run.
Our tempered glass weathered the hits best because it’s tougher and safer than generally used annealed glass.
All About Physics
It takes a speed of more than 100 mph and a height greater than 100 feet to send a baseball out of the park.
In Wrigley’s scenario, we determined the baseballs would be traveling at about 60 mph upon impact with windows.
But we exceeded requirements 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 propelling toward your residence, there are a variety of reasons to choose durable, 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 raising the next great baseball player.
Consider the strengths and highlights of Pella tempered glass options:
- Toughened glass much like what is used in car windows.
- Used where injuries from broken glass are a concern.
- Usually shatters into small, square parts rather than sharp shards if broken.
- Glass doesn’t come 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 Peoria at 309-306-3893. Or, request a free, in-home consultation online.
