Certain Pella® windows can halt flying baseballs and others can weather hurricane-force winds. How?
In regard 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 remains intact. We use our hurricane cannon to launch the wood, which covers 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could design a hurricane window with impact-resistant glass, surely we could find a resolution that could protect from home runs from Major League Baseball teams.
When Pella was contacted to help outfit a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.
We retrofitted our hurricane cannon to test the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would reconstruct the power of a home run.
Our tempered glass resisted the home runs best because it’s more durable and safer than commonly used annealed glass.
All About Physics
It warrants a speed surpassing 100 mph and a height exceeding 100 feet to send a baseball out of the park.
In Wrigley’s scenario, we found the baseballs would be moving at about 60 mph upon striking windows.
But we went above and beyond 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 hurling at your windows, there are a lot of reasons to choose durable, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an extra level of safety from their windows or patio doors. Or those who are raising the next great baseball player.
Consider the advantages and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where injuries from broken glass are a concern.
- Normally fragments into small, square fragments rather than sharp shards if broken.
- Glass doesn’t fall apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To learn more about impact windows and if they may be right for your home, call Pella of Timonium at 301-354-3633. Or, book a free, in-home consultation online.
