Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can stop fast-moving baseballs and others can withstand hurricane-force winds. How?
When it comes to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are thoroughly tested for impact resistance.
Tests consist of blasting a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to launch the wood, which covers 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 come up with a solution that could protect from 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 exactly 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 force of a home run.
Our tempered glass withstood the home runs best because it’s tougher and safer than standard annealed glass.
All About Physics
It warrants a speed surpassing 100 mph and a height exceeding 100 feet to shoot a baseball out of the park.
In Wrigley’s case, we determined the baseballs would be going at about 60 mph upon impact with 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 a lot of reasons to select strong, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an additional level of protection from their windows or patio doors. Or those who are developing the next great baseball player.
Consider the benefits 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.
- Normally fragments into small, square parts rather than 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 Mankato at 507-625-6933. Or, schedule a free, in-home consultation online.
