Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can halt speeding baseballs and others can resist 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 involve blasting a two-by-four at the window to ensure glass stays intact. We use our hurricane cannon to launch 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 find a fix that could stop home runs from Major League Baseball teams.

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

We modified our hurricane cannon to test 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 weathered the hits best because it’s more durable and safer than commonly used annealed glass.

All About Physics

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

In Wrigley’s scenario, we learned the baseballs would be moving at about 60 mph upon striking windows.

But we exceeded requirements and tested 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 windows, there are many reasons to use durable, tempered glass in your Pella windows and doors.

It’s great for homeowners who want an extra level of protection 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:

  • Strong glass similar to what is used in car windows.
  • Used where injuries from broken glass are a concern.
  • Usually shatters into small, square parts 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 Minneapolis at 612-249-7371. Or, schedule a free, in-home consultation online.
