Certain Pella® windows can put a stop to flying 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 make sure glass remains intact. We use our hurricane cannon to fire the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We thought, if we could design a hurricane window with impact-resistant glass, surely we could discover a solution that could stop home runs from Major League Baseball teams.
When Pella was approached to help equip a historic building near Wrigley Field with home run-resistant windows, that’s precisely 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 reconstruct the power 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 requires a speed surpassing 100 mph and a height exceeding 100 feet to send a baseball out of the park.
In Wrigley’s situation, we determined the baseballs would be traveling 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 concerned about an MLB home run hurling at your residence, there are many reasons to choose durable, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an added level of protection from their windows or patio doors. Or those who are developing the next great baseball player.
Consider the advantages 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.
- Generally breaks into small, square pieces as opposed to sharp shards if broken.
- Glass doesn’t come 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 Tysons Corner at 301-354-3689. Or, book a free, in-home consultation online.
