Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can halt fast-moving baseballs and others can withstand 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 firing a two-by-four at the window to verify glass keeps intact. We use our hurricane cannon to propel the wood, which travels 50 feet per second.

It Started with Hurricane Testing

We concluded, if we could engineer a hurricane window with impact-resistant glass, surely we could find a resolution that could halt home runs from Major League Baseball teams.

When Pella was contacted to help outfit a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.

We overhauled our hurricane cannon to experiment on the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would mimic the force of a home run.

Our tempered glass resisted the home runs best because it’s stronger and safer than generally used annealed glass.

All About Physics

It takes a speed surpassing 100 mph and a height of more than 100 feet to shoot a baseball out of the park.

In Wrigley’s scenario, we determined the baseballs would be traveling at about 60 mph upon striking 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 strong, tempered glass in your Pella windows and doors.

It’s good for homeowners who want an extra level of protection from their windows or patio doors. Or those who are raising the next great baseball player.

Review the benefits and highlights of Pella tempered glass options:

  • Strong glass like what is used in car windows.
  • Used where injuries from broken glass are a concern.
  • Normally fragments into small, square fragments rather than sharp shards if broken.
  • Glass doesn’t break 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 Denver at (888) 841-5667. Or, schedule a free, in-home consultation online.
