Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can stop flying 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 stays intact. We use our hurricane cannon to propel 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 discover a fix that could protect from home runs from Major League Baseball teams.
When Pella was approached to help outfit a historic building by Wrigley Field with home run-resistant windows, that’s exactly what we did.
We modified our hurricane cannon to experiment on the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would mimic the power of a home run.
Our tempered glass weathered the hits best because it’s tougher and safer than commonly used annealed glass.
All About Physics
It requires a speed faster than 100 mph and a height exceeding 100 feet to shoot a baseball out of the park.
In Wrigley’s situation, we learned the baseballs would be moving at about 60 mph upon hitting windows.
But we exceeded requirements and checked impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not thinking about an MLB home run being launched at your residence, there are many reasons to use strong, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an extra level of security from their windows or patio doors. Or those who are developing the next great baseball player.
Review 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 pieces 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 discover more about impact windows and if they may be right for your home, call Pella of Greenville, NC at 252-294-6432. Or, request a free, in-home consultation online.
