Certain Pella® windows can halt fast-moving 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 include firing 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 figured, if we could create a hurricane window with impact-resistant glass, surely we could find a solution that could halt home runs from Major League Baseball teams.
When Pella was asked to help outfit a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.
We overhauled our hurricane cannon to test the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would recreate the speed of a home run.
Our tempered glass withstood the hits best because it’s more durable and safer than generally used annealed glass.
All About Physics
It warrants a speed surpassing 100 mph and a height greater than 100 feet to launch a baseball out of the park.
In Wrigley’s scenario, we found the baseballs would be traveling at about 60 mph upon hitting 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 concerned about an MLB home run propelling toward your windows, there are a lot of reasons to use durable, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an extra level of safety from their windows or patio doors. Or those who are developing the next great baseball player.
Look at the strengths and highlights of Pella tempered glass options:
- Durable glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Usually shatters into small, square parts as opposed to sharp shards if broken.
- Glass doesn’t fall 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 Tucson at 520-989-3300. Or, book a free, in-home consultation online.
