Certain Pella® windows can stop 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 thoroughly tested for impact resistance.
Tests include blasting a two-by-four at the window to verify glass stays intact. We use our hurricane cannon to launch the wood, which moves 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 discover a fix that could protect from home runs from Major League Baseball teams.
When Pella was approached to help outfit a historic building outside of Wrigley Field with home run-resistant windows, that’s just what we did.
We retrofitted our hurricane cannon to evaluate the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would reconstruct the force of a home run.
Our tempered glass withstood the home runs best because it’s stronger and safer than commonly used annealed glass.
All About Physics
It requires a speed of more than 100 mph and a height exceeding 100 feet to launch a baseball out of the park.
In Wrigley’s situation, we found the baseballs would be traveling at about 60 mph upon impact with 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 thinking about an MLB home run being launched at your residence, there are a variety of reasons to use tough, 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.
Review the strengths and highlights of Pella tempered glass options:
- Strong glass much like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Normally fragments into small, square parts 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 discover more about impact windows and if they may be right for your home, call Pella of Westerly at 401-315-7032. Or, book a free, in-home consultation online.
