Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can stop flying baseballs and others can resist hurricane-force winds. How?

As far as hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.

Tests include shooting a two-by-four at the window to verify glass stays 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 engineer a hurricane window with impact-resistant glass, surely we could discover a resolution that could stop 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 exactly what we did.

We overhauled our hurricane cannon to test the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would mimic the power of a home run.

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

All About Physics

It requires a speed surpassing 100 mph and a height exceeding 100 feet to launch a baseball out of the park.

In Wrigley’s situation, we determined the baseballs would be moving 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 concerned about an MLB home run propelling toward your home, there are a lot of reasons to select tough, tempered glass in your Pella windows and doors.

It’s ideal for homeowners who want an additional level of protection from their windows or patio doors. Or those who are bringing up the next great baseball player.

Consider the advantages and highlights of Pella tempered glass options:

  • Strong glass similar to what is used in car windows.
  • Used where damages from broken glass are a concern.
  • Normally fragments into small, square pieces as opposed to 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 Davenport at 563-202-8576. Or, request a free, in-home consultation online.
