Certain Pella® windows can stop speeding 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 include blasting a two-by-four at the window to ensure glass keeps 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 create a hurricane window with impact-resistant glass, surely we could find a fix that could stop home runs from Major League Baseball teams.
When Pella was asked to help equip a historic building near Wrigley Field with home run-resistant windows, that’s exactly what we did.
We retrofitted our hurricane cannon to evaluate the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would recreate the force of a home run.
Our tempered glass withstood the hits 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 exceeding 100 feet to shoot a baseball out of the park.
In Wrigley’s scenario, we determined the baseballs would be going at about 60 mph upon hitting 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 propelling toward your home, there are a variety of reasons to select durable, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an additional level of security from their windows or patio doors. Or those who are developing the next great baseball player.
Look at the benefits 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 pieces 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 discover more about impact windows and if they may be right for your home, call Pella of Washington DC at (202) 810-6799. Or, request a free, in-home consultation online.
