Certain Pella® windows can halt 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 thoroughly tested for impact resistance.
Tests involve shooting a two-by-four at the window to verify glass stays intact. We use our hurricane cannon to propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, if we could engineer a hurricane window with impact-resistant glass, surely we could come up with a solution that could halt 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 overhauled our hurricane cannon to evaluate 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 resisted the home runs best because it’s more durable and safer than standard annealed glass.
All About Physics
It takes a speed surpassing 100 mph and a height of more than 100 feet to send a baseball out of the park.
In Wrigley’s scenario, we determined the baseballs would be going at about 60 mph upon impact with 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 worried about an MLB home run propelling toward your windows, there are many reasons to choose durable, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an additional level of safety from their windows or patio doors. Or those who are developing the next great baseball player.
Consider the strengths and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Normally fragments into small, square pieces instead of 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 Boone at 828-202-8489. Or, request a free, in-home consultation online.
