Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can stop speeding baseballs and others can withstand 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 firing a two-by-four at the window to verify glass stays intact. We use our hurricane cannon to launch the wood, which covers 50 feet per second.

It Started with Hurricane Testing

We concluded, if we could create 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 supply a historic building near Wrigley Field with home run-resistant windows, that’s just what we did.

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

Our tempered glass weathered the hits 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 of more than 100 feet to send a baseball out of the park.

In Wrigley’s situation, we found the baseballs would be moving at about 60 mph upon hitting windows.

But we went above and beyond 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 hurling at your windows, there are a lot of reasons to select tough, tempered glass in your Pella windows and doors.

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

Look at the strengths and highlights of Pella tempered glass options:

  • Toughened glass much like what is used in car windows.
  • Used where cuts from broken glass are a concern.
  • Usually shatters 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 find out more about impact windows and if they may be right for your home, call Pella of Gaithersburg at 202-810-6722. Or, book a free, in-home consultation online.
